Case study: BBNet Chooses Aviat for Rural Broadband in Ireland
The biggest deployment challenge for the Aviat link was the region’s topology and configuration of the system for optimal reliability as it transmitted over hilly terrain and farmland. The link also crosses over the Shannon Estuary, which constitutes 16 percent
of the path. Reflection is the biggest challenge when transmitting radio frequency over water. It can result in multi-path signals, which can slow the network down considerably. Tidal patterns also were considerations, as changing tides alter thermal conditions and vary the degree of reflection. It is challenging to install a high-capacity link with a high modulation scheme over water.

Case study: How Africell Sierra Leone enhanced the capacity of its 26 link backbone with 4x4 MIMO
Africell Sierra Leone struggled with the lack of spectrum in their region and their subsequent inability to provide high capacity to their radio access network. They needed a cost-effective alternative to connecting fiber to their sites. Aviat proposed solving the capacity constraint using MIMO technology to get the most out of the available spectrum without degrading any performance of the microwave network.

Application note: WTM 4000 built-in spectrum analyzer
WTM 4000 Spectrum Analyzer feature is a built-in and license-free diagnostic feature to enable the user to check for potential interfering signals and measure the level of interference across the desired frequency range (limited by the diplexer bandwidth) and check the RSL (received signal level) of the interfering signal in 1.4 MHz steps.

Case study: Vodafone Fiji successfully deploys LOS MIMO link using Aviat WTM 4000 solution
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.
