Vodafone Fiji needed a solution to provide over 2 Gbps of capacity over a distance of more than 6.5 kilometers, but there was only one problem: lack of frequency spectrum. Vodafone only had a single 80 MHz channel allocation in the 11 GHz band. Aviat was able to design a link using their WTM 4000 all-outdoor radio platform, employing Line-of-Sight (LOS) MIMO to quadruple the efficiency of the single available frequency channel.

The wave of virtualization is catching up in every vertical of technology, and new protocols are being defined to improve functionality and management of emerging technologies. Software-defined Networking, or SDN, is one of those technologies. SDN was first used in data centers to configure network devices connecting virtual machines amongst themselves and the internet on a massive scale and is now being adapted into other applications and technologies.

Segment Routing is a new routing paradigm that aims to optimize, simplify, and improve the scalability of IP/MPLS based networks. Segment Routing utilizes source-based routing scheme where a network node steers a packet based on a list of instructions carried in the packet header (called “segments”). The list of segments carried in the packet header provide a strict or a loose specification of the required network path or tunnel eliminating the need for transit nodes to hold and maintain that path/tunnel information.

For new entrants and smaller WISPs, cost is often the major factor in infrastructure procurement. However, many WISPs who used to be in those categories are today enjoying significant growth, prompting them to rethink infrastructure investments as part of their overall business plan.

In an era of growing security threats from terrorism, border security and immigration, attacks on critical infrastructure and general public unrest, the issue of security in communication networks is more important than ever. The new generation of IP-based wireless technology is an enabler for applications such as mobile commerce, voice over IP (VoIP) and high-definition video delivery to smartphones, but it has also opened some sinkholes in the foundation that pre-LTE architectures and applications have established.

The new and exciting news in Government Funding – The latest round of CAF-II has been awarded and now WISPs and Rural Operators are expanding their coverage into rural areas that have little or no Internet access.
What comprises complex rural networks? A combination of microwave Point-to-Point and Point-to-Multipoint technologies are being used to reach remote WISP and Rural Operator customers and deliver high-speed internet: up to 20 Gbps on the backbone and hundreds of megabits per household.

Commercial mobile networks in the US are morphing into critical infrastructure as homeowners abandon their landline phones and rely instead on their mobile phones. Critical alerts, evacuation information, and family reconnections are relying on mobile networks in times of disasters. Unfortunately, those are exactly the times that the mobile network infrastructure is most severely tested and in recent past has shown it cannot stand up to the rigors of these disasters. The US Federal Government (FCC) and state/regional entities are looking at ways to limit the impacts of these disasters.

Papua New Guinea, or PNG, is one half of the island of New Guinea, along with offshore islands, located in the South Pacific immediately to the north of the Australian continent. The country is rugged and heavily covered by dense rainforest, which presents enormous challenges when it comes to establishing a national communications infrastructure. In most cases, deploying fiber routes is simply not practical nor affordable. Wireless is the only answer in these cases.
When people think of mobile security, they usually think of encryption for their smartphones, tablet computers such as the BlackBerry PlayBook or other wireless devices. Or they think of a remote “wipe” capability that can render any lost device blank of any data if some unauthorized party did in fact try to enter the device illegally. These wireless solutions are all state-of-the-art thinking in the mobile security community. And many wireless equipment OEMs and third-party mobile security providers offer them.

In every school across America, children are taught to revere the era of the “Space Race” and its impact on the human footprint. Whether it was in the private or public sector, the world was electric with an insatiable desire to push the boundaries of technology and human capabilities. Today, the next “Space Race” is already afoot, down on the ground.
