The Unwired network uses fibre optic transmission at major aggregation sites to transport customer traffic back into the core network for access to the Internet, or to provide VPN connectivity between customer sites.
The Unwired design philosophy is to use one fibre site for backhaul to the core for every seven microwave access sites.
These fibre optic connected sites are connected to other fibre optic sites via high speed microwave links thus providing redundancy to the fibre transmission.
If a fibre connection was to fail, traffic will be diverted over the wireless infrastructure to a secondary fibre site with sufficient capacity to carry the additional traffic load. When the fibre break is restored, traffic will automatically be restored to the repaired fibre optic path.
