Multi-Band, not microwave or millimeter-wave, is the solution for 5G Backhaul.
Why? Microwave bands are limited in capacity, particularly in countries and bands where spectrum is limited due to congestion. Even if you can get additional frequencies, scaling capacity means aggregating multiple channels that results in high equipment costs and potentially expensive recurring spectrum fees. E-Band alone is not sufficient either. With more bandwidth available that enables higher capacities, E-Band suffers from a number of potential limitations, from short link distances and high susceptibility to rain outage and pole/tower sway to difficult and time-consuming installation/antenna alignment.Read More
Aviat Design, Aviat’s cloud-based link planning application, supports WTM 4800 E-Band and Multi-band designs. Aviat Design is the industry’s first and only integrated Multi-band link design solution showing a combined view of availability and capacity for the link. This enables easy, fast, intuitive E-Band and Multi-Band designs (all specs included, no pathloss files to download or update, easy cloud access). Popular design tools will require 2 separate link calculations for Multi-Band, and will not result in a combined design for the link, making it virtually impossible to understand the expected link performance or capacity or estimate the proper antenna size. Aviat Design is FREE for use at www.aviatcloud.com.Read More
Multi-Band involves combining E-Band (70-80GHz) with traditional microwave (6-42GHz) on a single microwave link, usually with a single antenna on each end. Multi-Band drastically improves availability and distance of E-Band links and addresses other issues like pole sway and antenna alignment. If you are thinking of E-Band or microwave, consider Multi-Band, in particular single-box Multi-Band. Check out our infographic below to find out how single-box Multi-Band means high value at a cost that makes sense.Read More
Most operators of WISP backhaul networks have had difficult experiences with Power over Ethernet (PoE) cabling solutions, affecting both the economics and operations of their networks. Today, Aviat Networks is recommending, with increasing frequency, a dual cable system: fiber to carry data at high speeds, and copper to carry DC power only. This solution offers significant advantages over CAT5 cabling, which carries both data and DC power over a single Ethernet cable.Read More
Earlier this month, Aviat announced that they will now be the exclusive distributor of microwave radio for NEC in North America. Aviat is hopeful for the success of this agreement with NEC and looks forward to expanding their suite of services and offerings.
Many have had questions about what this agreement means for NEC and Aviat moving forward. Read through the questions and answers below to learn how this agreement will impact the future of microwave radio backhaul solutions in the US.Read More
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.Read More

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.Read More
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.Read More

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.Read More
