Small businesses have a multitude of business technologies now, more than ever, with the advancements of larger companies trickling down to smaller companies. Even Voice over IP (VoIP) phone systems are now well within reach for companies that are looking for enterprise features on a small business budget. Small business phone systems used to be extremely basic: maybe one or two phones with one or two lines and some notepads for taking messages. With VoIP and other types of IP-based telephony, your phone system can be integrated with your data network, providing advanced features and more potential for long-term growth.

An IP-based voice system provides business-class phone solutions at an affordable, convenient and expandable cost than a traditional PBX phone system. A traditional PBX, or private branch exchange, connects all of the telephones within a company and then connects them to the public switched telephone network (PSTN). This is the system that usually requires dialing ‘9’ first to make external calls.

An IP PBX is a private phone system that delivers calls over your IP network. The IP-based voice system can also connect to the PSTN or the IP telephony provider’s network, allowing the business to place and receive calls to any phone number anywhere in the world. When an IP PBX includes VoIP technology, you can make long-distance calls over the Internet.

The introduction of VoIP has been revolutionary, allowing small businesses to get phone service exclusively over the internet. When it comes to VoIP-based systems, there are free or inexpensive services, but those groups are usually only effective with a couple of phone lines and require headset-equipped computers and traditional telephones. Alternatively, you can have a complete IPT solution that integrates voice, video and data. Many small businesses opt for the hybrid system that incorporates VoIP capabilities into your existing phone system, for ease of integration and cost.

IP-based phone systems offer better convenience and expandability versus traditional PBX. A small business IP PBX gives companies more world-class features that would usually be fairly expensive within a regular PBX system. Due to their smaller size and specialized functions, an IP-based voice system designed for small businesses is much easier to set up and maintain. Some of the high-end business features available with an IP voice system include multiple voicemail accounts, call forwarding and call transfer, three-way conferencing, automated attendant (for those that want quick answers without having to talk to a live associate), voicemail to email notifications and a company directory.

In addition to being less expensive to install than a traditional PBX solution, an IP-based voice system is essentially a free long-distance service. With VoIP, your data and phone networks are combined, allowing your employees to make long-distance calls over your Internet connection. Just make sure the network and the Internet bandwidth can handle the increased traffic.

An IP-based phone system offers many inherent benefits for small businesses. In general, they’re easier and cheaper to install. Also, they’re also very versatile, with the ability to integrate analog lines. IP-based phone systems are also more easily expandable than traditional PBX systems. Instead of installing additional landlines in your office, you can add phones as needed, though a switch may be required to support them. If your small business chooses to go into hosted IP, then the IP service provider would have the necessary equipment to expand your IP system as needed. Overall, the IP-based system provides improved customer service through a professional interface. The auto attendant can greet customers with a recorded message and route incoming calls to the correct extension, making a good first impression with your customers.

If many of these features seem extraordinary, then it’s fine to stay with a basic phone system. However, you don’t want your small business to fall behind with your competitors, who are adapting to the changing markets. You also don’t want to stay stagnant; a small business can become a big business in no time with the right phone system giving both their customers and their employees the tools to grow the company and reach for higher heights of economic success.

How to Repair an Alcatel-Lucent MPR9500

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

The Alcatel-Lucent 9500 Microwave Packet Radio (MPR) is one of the best microwave radios on the market, enabling smooth transformation of backhaul networks from TDM to IP and providing a very efficient transport medium for multimedia traffic. However, since Ethernet radios are becoming more commonplace, it’s important to keep the legacy 9500 MPR up and running at optimal performance. Radio techs are being trained to handle more technical challenges, mostly in telecommunications but also in handling microwave radios since, currently, that requires the presence of an expensive specialist. To keep your costs low and become more familiar with the 9500 MPR, it’s best to get an idea of how the device works.

Ethernet technology had the foresight to hybridize the technology to the original TDM matrix so that companies didn’t have to grow faster than their means to maintain their business. The Alcatel-Lucent 9500 MPR has that same hybridization which is why it’s held its; position as a long-life hardware upgrade for small and large businesses alike.

The 9500 MPR integrates aggregate data packing to optimize system upgrades from older networks to more modern Ethernet networking. To cut back on field repairs, the 9500 MPR has monitors that alert it to any data losses, electrical disruptions and weather anomalies that may damage the electronics. This does not replace field repairs, as like all microwave radios, it’s required. However, with the knowledge of the basics of microwave radio repair, those field issues can be a snap. In the case of extensive repair work, it’s best to call in an expert certified to handle the 9500 MPR.

The 9500 MPR has some of the most advanced, upgraded software on the market and that can be downloaded by a qualified IT staff. If the device was purchased through a third party servicer, it’ll be easier to let them handle the upgrades, to preserve the system’s integrity. It’s important to pay attention to the required maintenance upgrades for obsolete operating software (which slows down your system) and maintaining the interoperability with support equipment (to prevent data from being compromised).

Check the User Manual
The 9500 MPR also has a dummy line that is used to test out upgraded software for reliability and corruption; this is outlined in the user’s manual. When software repairs are needed, always test the upgraded software on the dummy line to prevent further data corruption problems down the road.

Perform Regular Maintenance Checks
The 9500 MPR’s life cycle can be extended through regular maintenance checks, on site, of the receiver, transmitter and the antenna system. Best practices include monitoring the MPR’s generators for the MPR, fencing the radio off from outside tampering, camera monitoring, security alarms and protection from the elements. It’s also good to have spare equipment or parts around to make maintenance easier and less costly.

Maintain a Network Checklist
Lastly, maintaining a networking checklist keeps tabs on the MPR throughout its use. This will make any support work and equipment and software implementation easier and faster. The checklist should include:

  • Performing monthly manual switchovers to test the microwave transmitters. Do the same for the physical systems and batteries to make sure nothing was missed.
  • Making sure the support equipment is rated for heavy weather conditions just in case the radio’s location isn’t easily accessible.
  • Maintain a weather checklist so any support equipment can be inspected and replaced as needed.
  • Perform bimonthly checks on the active and redundant systems to maintain response and recovery times during an outage.

If you’re in a bind when it comes to repairing your 9500 MPR system, seek the help of a third party vendor like Single Source Communications.


How to Increase the Bandwidth of Cisco Routers

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

Cisco routerBusinesses with large networks need fast Internet connections to ensure that every computer can use the Internet smoothly. However, your system – either for a small business or home – along with some other systems in the network, may not effectively maximize your connection’s bandwidth. This is especially so if your Cisco router is configured to prioritize certain applications, such as video conferencing. Maximize your network’s bandwidth by disabling the Internet Access Priority feature so every Internet-enabled application can take full advantage of your connection’s full bandwidth capabilities whenever needed.

The bandwidth of a router refers to many different things. If your goal is to increase network speed, then you need to consider more factors than just the router. A router’s bandwidth is measured by your connection to the router, the router’s ability to handle and forward requests, and the outbound bandwidth provided to the router.

The most direct way to increase a router’s speed is to make sure less of its bandwidth is used for overhead, which includes the bits of information attached to every data packet that informs other routers what type of packet it is, where it’s coming from and where it’s going. The fewer individual packets there are, the less overall bandwidth is wasted on overhead. A more efficient packet is one that uses the Maximum Transmission Unit, or MTU. The MTU tells the router how large a piece of data can be before breaking it into another packet. Modifying the MTU to a larger size only increases your router performance when transferring large files – small transactions are virtually unaffected.

Routers often include security or compatibility services for ease of use. Each of these functions consume resources, which can affect overall throughput. Many routers, even, include Stateful Packet Inspection functions, or SPIs, for security. Disabling SPI increases the bandwidth available to your router. However, it’s not recommended to disable this service without having another security measure in place, such as a firewall.

Depending on your router, channel bonding can allow you to make two or more ports act as if they were one, effectively multiplying the available bandwidth, respectively. Channel bonding is used by ISPs to offer speeds beyond what a telephone line or single cable channel normally would. This is also called link aggregation, which works more in line with adding more lanes to travel rather than increasing the actual travel speed.

Increasing speed can also be as simple as setting the performance parameters based on the data traffic’s importance and sensitivity to data delay, or jitter, and latency, especially with a wireless router. Eliminating compatibility for older 802.11b-based devices speeds up the connection for all common 802.11g-based devices that are connected to your router. However, don’t try this with the newer 802.11n-based routers, even though they are backwards compatible with 802.11g devices.

When possible, connect via a wired port instead of through wireless. Wired ports provide an unshared 100-1K Mbps of bandwidth from your PC to the router. With wireless, your total bandwidth is divided between every other wireless device, resulting in a slowdown. Like most of us, wireless is a convenient and preferred mode of sharing bandwidth amongst several devices, so at the very least, secure the wireless frequency, keeping the bandwidth from distributing to unauthorized users, like your neighbors or snoopers on your network.

Reducing Network Latency with an Integrated Microwave Solution

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

Network latency indicates any kind of delay that happens in data communication over a network. Low-latency networks indicates small delays in network connections. Longer delays are called high-latency connections. Latency is important to all network operators. The lower the end‑to‑end delay the better it is for all types of applications.

Reduce network delays with microwave  solutions

Latency is the sum of many factors such as:

  1. Propagation delay – amount of time it takes for the head of the signal to travel from the sender to the receiver.
  2. Serialization delay – the time it takes for a unit of data, such as a packet, to be serialized for transmission on a narrow (or, serial) channel such as a cable.
  3. Routing and switching – In switching, packets are transferred from source to destination using MAC addresses. Switching is done within the network. Routing is a done between two networks using IP addresses.
  4. Queuing and buffering – With queuing, data packets are collected to be transmitted by a network device. Buffering is the temporary placement of data into regions of physical memory storage.

For every packet microwave backhaul connection, an IP router processes the IP packets and forwards them. Along the way, the router adds latency, or delays, which is on top of the latency already applied from switches and microwave radio units, which packets accumulate. Hybrid microwave networks that contain discrete IP routers and microwave radios necessarily have to endure this latency.

Microwave radios add to the lower latency because of the natural propagation of radio waves through air. Terrestrial microwave radio signals travel through the atmosphere near the earth’s surface at very close to the speed of light, approximately 1.5 times faster than fiber optics. This gives microwave networks a huge latency advantage over fiber networks of an equivalent distance, averaging 5.38 vs. 8.44 microseconds per mile. Latency is critically important to mobile network operators (MNOs) for LTE Advanced features like coordinated multi‑point (COMP) and multiple-input and multiple-output (MIMO), which require extremely tight latency. Lower latency is critical for synchronization and HD video transport.

Microwave signals are the best for lower latency because of:

  1. Faster Propagation. Microwave signals travel through the air about 50% faster than light through optical fiber. Latency in a data communications circuit will consequently be longer over a fiber circuit than a microwave circuit of the exact same length.
  2. Straighter Routes. Microwave networks have shorter routes, reducing the total network distance, further improving latency. Microwave links can overcome topographical obstacles such as rivers, mountains and highways while optical networks in many cases have to go around them or follow existing roads or bridges.

Microwave systems do have two disadvantages compared to fiber optic systems. First, microwave radios have significantly lower maximum bandwidth due to their much lower frequencies and longer wavelengths. While most modern long distance microwave radio systems have an (N x 100) Megabits per second payload, electromagnetic physics and regulatory limits on channel sizes prevents them from ever truly matching fiber optics’ consistent 100+ Gigabits per second single carrier bandwidths.

Secondly, since microwave radios require line of sight from one antenna and radio terminal to the next, there’re topographical limitations (approximately 30 – 50 miles) between relay points. So, over thousands of miles, a microwave radio network will require many more relay sites to receive, process and then retransmit a signal. All that digital processing adds latency. Fiber optic networks require the same relay pit stops, just not as many since they don’t run through line of sight.

Regardless, despite the higher number of regeneration points, with a 1.5 X faster propagation velocity advantage, microwave networks continuously prove to be significantly faster than even the fastest available fiber optic networks.

Is Your Business’ LAN Ready for the Future?

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

If you’ve ever done a tricky do it yourself project at home, there’s eventually going to come the urge to just chuck it all out and start it from scratch. However, when it comes to a corporate network, it’s much harder to explain why large parts of the current infrastructure has to be upended to make room for the new and improved. Companies must know what to listen for, how to analyze and interpret the data, and how to respond. What’s more, they must then be able to act quickly on the information. In general, effective digital strategies are less about acquiring and implementing the right technology than about reconfiguring your business to take advantage of the information these technologies give you access to.

Future of LAN for Business

The objectives of a company’s digital strategy also differ depending on digital maturity. Regardless of maturity level, most companies want to use digital technologies to improve customer relationships. Organizational culture is also critical to effectively leveraging digital technologies in the workplace.

As a result, most companies are investing in the development and training of digitally savvy talent. As technology improves, so do the users, but their skills and abilities that aren’t purely technical. One of the most important abilities necessary is knowing the business well, conceptualizing how new digital technologies can impact current business processes.

As companies continue to advance, a shift in corporate mindset must occur to successfully compete. Consider the following:

  1. Do you have a digital strategy for the future that considers the full organization?
  2. Is your company culture allowing your digital initiatives to succeed?
  3. Does your organization have the talent and skills that you need? Are your employees being given the right skills to succeed in a digital environment?
  4. What do employees need to succeed? How might your company’s existing digital infrastructure be impeding your employees’ ability to succeed in a changing competitive environment?

When looking to make the upgrades and you’ve considered what you need, start small and build outwards.

  1. Stick to modular equipment, centralized management. To avoid rip-out upgrades later, consider buying a centralized wireless LAN (WLAN) switch that will let you upgrade access points easily.
  2. Make way for 10G and avoid bottlenecks. 10G is the automatic choice today in data centers. Current wiring closet switches have one or more uploads to the corporate network and nearly every new PC has 1G bit Ethernet adaptability. 10G prevents the bottlenecks and congestion of multiple data packets. It’s best to consider upgrading your network to the higher bandwidth as soon as possible.
  3. Buy flexibility with Power over Ethernet. For added and future deployments of VoIP handsets, wireless access points and security cameras, Power over Ethernet (PoE) technology gives generous flexibility with regard to where the devices can live. In a few years, you’ll see even more devices taking advantage of PoE, such as laptop computers. Luckily, it’s not hard to keep this option open because PoE doesn’t mandate any change to Ethernet cabling. At a basic level, all you need is standard Category 5e wiring.

As you consider your company’s digital strategy, keep in mind that the road map you develop will shift as technology advances and your competitors make their own digital strategies. While it may be very difficult to predict future technologies, business success will depend less on the technologies themselves and more on your company’s ability to implement them innovatively.

TDD Radio Systems: EX-5i vs. EX-2.4i Series

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

Time Division Duplex, or TDD, is used with short burst data transmissions going from the transmitter and receiver. Since the transmission periods are relatively short, no time delays are noticed on voice transmissions resulting from the time delays introduced by using TDD.

The EX-2.4i series of digital microwave radios is the first family of carrier-class TDD radios available in the 2.4 GHz ISM band. It delivers up to 216 Mbps of aggregate user throughput and up to sixteen T1/E1s at distances of up to 30 miles. The EX-2.4i series was designed to meet demanding backhaul requirements of enterprise organizations and service providers seeking the accessibility benefits of an all-indoor configuration.

The EX5i series of digital microwave radios is the first family of triband, carrier-class TDD radios available in the 5.2 – 5.8 GHz bands. The EX-5i series is the most widely used 5 GHz mobile backhaul radio in the North American Tier 1 carrier networks. This series delivers up to 216 Mbps of aggregate user throughput and up to sixteen T1/E1s at distances of up to 25 miles. The EX-5i series is designed to meet demanding backhaul requirements of enterprise organizations and service providers seeking the accessibility benefits of an all-indoor configuration.

Comparing the two series, they have fairly similar attributes. Both the EX-2.4i and the EX-5i series radios combine native TDM and native Ethernet transport with low, fixed latency to deliver guaranteed throughput and high service quality. The Exalt backhaul radio systems are designed to meet the demands of each of three scenarios that many clients see at existing base stations:

  1. The site requires additional capacity due to the rise in data traffic
  2. Interference is affecting the legacy radio link and causing service outages.
  3. Ethernet capability must be added to the backhaul link to accommodate a 3G or future LTE Node.

The radios are capable of ensuring the low, fixed latency required by TDM networks and both guaranteed a 99.999% throughput availability over long ranges. The systems for the 2.4 GHz and 5 GHz bands have exceptional interference resistance and provide the user with a high degree of control over configuration parameters. As a result, the systems minimize the likelihood that any interference will ever affect user traffic. The notable differences between the two radio bands is the range capacity.

Exalt Radio Systems Radio Systems: EX-5i vs. EX-2.4i Series

Range capabilities vary by band and sub-band, with the 2.4 GHz systems offering the greatest range capability (over 30 miles for the EX-2.4i vs. 25 miles for the EX-5i).

The Introduction of a Smart Data Center

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

As the demands of traditional data centers increase so does the need to revamp our approach to systems architecture. Smart data centers are no longer IT focused but rather focus on the needs of the business. Breaking down operational silos and enabling the data center for agility, availability and scalability support the business in a much more effective way than IT practices of the past. As data centers continue to face rigorous demands, future infrastructure must address both the physical and logical layers to accelerate the business value of IT and drive organizational results.

Demands of the data center
Businesses rely on technology. So much so that IT could be termed the backbone of every organization. As the evolution of the IT-Business relationship progresses, IT is faced with accommodating a vast amount of demands from the business:

  • Availability and flexibility
  • Dealing with space limitations
  • Compliance with industry standards
  • Real-time data/services delivery
  • Service delivery over a wide geographical spectrum
  • Service-centric models

Enabling IT to become a service broker for the business is the future of IT practices. Internal customers are increasingly looking to receive the same experience they get from their smart devices at work which means the option to self-serve applications on demand. An agile infrastructure is necessary in order to make this possible and IT professionals are looking for ways to automate these services.

Flexible, end-to-end solutions are infiltrating the data center space. As companies grow increasingly dependent on the technology that supports them, IT professionals are faced with integrating traditional data center infrastructures with proprietary systems which has opened the door for interoperability between all business systems. While implementing such solutions can be challenging, the financial and operational benefits are worth the effort.

Data center management
Ensuring that energy, equipment and square footage are used as efficiently as possible is a primary responsibility for data center managers. Excel spreadsheets and visual spot checking have been replaced with central management systems enabling IT to gain a holistic, single-pain view of the data center. Optimizing asset performance and enabling design and management opportunities through data center management systems is being integrated broadly as the benefits of doing so are vast.

Software defined
As cloud computing and virtualization continue to grow in the data center space, IT professionals are being asked to look for software defined technologies. While we may first think of virtualization when mentioning software defined technologies, these advancements also go a long way in terms of utilizing existing hardware to their full capacity. Administrators are able to create hundreds of instances on a single network component which helps control data center workloads. The primary areas which are moving to the software defined realm are:

  • Software defined networking
  • Software defined security
  • Software defined storage

Cloud utilization
Businesses are taking their data center efficiencies to the next level by moving workloads to the cloud. As it relates to IT administrators, provisioning applications, deciphering which workloads are appropriate to move to the cloud and better using underlying components provide an entirely different spectrum to the profession.

IT leadership and business executives will continue to look for more ways to better utilize their technologies as they relate to the ever changing needs of the organization and the smart data center will be at the forefront of these efforts. 


Telecom Optimization Trends and Opportunities for 2017

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

There’s a relentless pace to the ever changing ICT industry as companies race against one another to stay competitive and modern in the ever-changing technology market. Technology advances at increasing speed with the development of more mobile devices, wearable technologies, such as smartwatches, and better globalized means of connectivity. Many companies see that the current trends and modes of operation are already becoming obsolete. The app-development culture of just a year ago is being rolled over by cloud computing and social media. It’s also getting harder to keep the attention of the younger, newly developed Millennials, who make up the majority of new technology consumers going into 2017.

telecom trends for 2017

The Ericsson Group, a multinational networking and telecommunications services company, has come up with a list of the top five trends that will direct the course of the ICT industry in 2017. According to Ericsson, the key to long-term success lies in a company’s ability to understand change almost before it happens, and then seize the opportunity to shape and evolve technologies to meet the trend. These five key technology trends will stimulate innovation in smart devices, VR and AI techniques and cloud computing and sourcing.

  1. First, technology is going to start spreading intelligence throughout the cloud. Connected smart machines (i.e. robots and autonomous vehicles) comprise the fundamentals to an evolving, networked society. Utilizing an enhanced cloud architecture, that distributes and shares machine intelligence, will connect smart devices together, enabling concerted intellectual performance at much higher levels.
  2. Second, there will be a higher degree of sensory development as technology is combined to increase data collection and analysis. This involves utilizing artificial intelligence techniques, which will ultimately collect massive amounts of data from a massive sensory network. This web of sensors will be merged and processed to create a high-level vantage point to review a given system.
  3. The third trend is an expansion of the first three: a feeling, interactive Internet. The internet is evolving year after year, introducing virtual reality and holographic interfaces to create a more expansive experience for users. 2017 will mark the beginnings of an evolution in web connectivity, where the interactions of humans and machines will begin to add more heightened experiences and sensations, bringing about a more intuitive and personalized Internet experience.
  4. The fourth trend is more in the field of networking and connections-based technologies. Communications networks fall into many categories, from social media to global video conferencing. There will be a definitive trend, according to Ericsson, that will fundamentally alter the way we network with one another and with the rest of the world.
  5. The fifth trend focuses on security and privacy, online. With so much of our personal information online, from our financial records to our favorite recipes, cyber security and general privacy are very serious issues for everyone, especially consumers, corporations and government agencies. With the rise of so many more connected and accessible technologies, as the previous trends point out, all of that convenience needs to be secured and it’s the most vital trend to look out for in the coming year.

Best Practices for Ultra Low Latency Microwave Networks

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

With the speed of the internet and telecommunications reaching an all-time high, there’s a need to reach out to new, developing technologies that will increase performance, lower costs and lead the industry into a new age of possibilities. That new technology is upon in the form of ultra-low latency microwave networks.

Low latency microwave network costs

Microwave technology has been around for over 50 years and has found a home in telecommunications networking across the globe. New developments have optimized microwave products to drive latency performance to the point of surpassing older fiber optic transmitters, especially over longer distances. There are new market opportunities for tapping into these innovations for service providers looking to expand their communications networks.

It’s one thing to have access to low latency technology and it’s another to know how to best use it to your advantage. The applications of low latency microwave technologies require the experience and expertise to design, deploy, operate and support such an advanced network. The beauty of Low Latency Microwave Networks is their speed. The transmission can arrive milliseconds earlier than the fastest fiber networking.

Microwaves move at a faster propagation, moving 50% faster than light when traveling through optical fiber. This technology is the basis behind satellite detection and data signal transmissions and receptors. Latency in data communications, or the time difference between sending a command and receiving the reply, will consequently take longer over a fiber circuit than a microwave circuit. Microwave signals also propagate through air at the same speed as light does in a vacuum, which makes it an ideal form of communication since there’s little chance of interference or refraction due to fiber optic cabling.

Microwave signals also have the benefit of following a straighter path than light. Microwave signals circumvent the topographical obstacles of land formations such as mountains, rivers and man-made constructions. Fiber optic cables are often forced to follow the paths of industry, limiting their versatility and diversity. More lines of cabling is more miles to travel.

Many factors go into determining usable end-to-end latency of a microwave link, however;

  1. The directness of route.
  2. Number of hops in the end-to-end transmission.
  3. The level of availability (high availability or not) in the environment.
  4. Operational efficiency

Network design is critical in ultra-low latency, since the enemy is distance. The longer the path, the longer it will take for microwave communications to reach the end. It’s important to optimize the path plans for ultra-low microwave latency microwave backhaul. Land surveys will tell if a microwave site already exists or if the topography can support a position, or a hop. The best way is to minimize the number of hops as much as possible to build a stronger, faster transmission network.
Once an ultra-low latency network is designed and deployed, the network needs to be up and running at peak performance. Total latency in any network requires additional latency due to data queuing delay, process delays, network design, the equipment’s configuration and, of course, distance.

Despite it all, microwave networks offer the better solution to low-latency communications. It surpasses as a transmission medium and it works in straight line paths. That’s a winning technology.


How to Get More Capacity from Your Tellabs TITAN 5500 System

Warning: getimagesize( [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /data/8/0/112/119/601445/user/613596/htdocs/wp-content/plugins/thrivehive/thrivehive.php on line 1916

Tellabs TITAN 5500 SystemTellabs introduced over a decade ago their Titan 5500 wideband digital cross-connect system in order to integrate voice, data, video and Internet services over a single fiber-optic network. AT the time (early 2000’s), the idea of uniting these mediums through a singular network was unheard of and many believed that Tellabs was biting off more than they could chew. However, the Titan 5500 proved to be a powerhouse, enabling cable and wireless to increase networking strength and efficiency, optimizing its high-speed processors to improve internet connections to both business and customers.

Now, Tellabs has decided to improve on their design. Introducing the Titan 5500 NGX-S Transport switch. The idea for the upgrade helps businesses open up new streams of revenue, dramatically lower their capital and operating costs and simplify their migration into new service delivery modes and methods.

The Tellabs 5500 NGX-S switch supports 100 percent wideband and broadband in single, powerful and compact system. It saves 30 percent in both capital and operational expenditures by fully integrating bandwidth management with transport functions. It also shrinks the floor space usage by 75 percent of its first generation counterpart. The Titan 5500 system is the largest wideband digital cross-connect in the industry. It gives carriers the ability to transport 100 gigabits of data per second, or approximately 688,000 simultaneous Internet calls. Its 2,048-port system allows service providers to improve reliability while reducing equipment and operations costs as their network grows to meet demand.

The Echo Cancellation and Voice Quality Enhancement (VQE) solutions in the 5500 system deliver superior voice quality in long-distance and wireless networks to over 300 customers in 70 countries. Tellabs uses an installed base of echo cancellation circuits to control echo and improve call quality. The Titan 5500’s Digital Cross-Connect System (DCS) Integrated Voice Quality Enhancement (iVQE) allows the higher quality voice operations, making it the system of choice for businesses looking to enhance their customer relations and improve service.

In addition to echo control, the 5500 system provides acoustic control, noise reduction, adaptive gain and voice level controls.

  1. With acoustic control, there’s protection from acoustic echo generated in wireless handsets and hands-free kits. This minimizes the clipping and static of most wireless devices and enhances double-talk performance.
  2. With noise reduction, background noise typically found in wireless environments is reduced, further improving call intelligibility.
  3. Adaptive gain enhances speech clarity in noisy environments by adjusting gain and spectral components of the signal going to and from the mobile user. This gives better quality voice calls with better clarity and cognition.
  4. Voice level controllers in the 5500 system adjust variations found in today’s multi-vendor, interconnected networks. Speech levels are modified and optimized to reduce distortion at lower levels and by bringing out the lower voice levels to higher volume, all while preserving the call integrity. As a result, speech clarity and intelligibility are greatly enhanced by maintaining consistent levels throughout the network. This alone reduces operating, capital and maintenance costs for the long-term.
