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.
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.
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.

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.
