This microwave digital radio from NEC was designed to meet the requirements of IP networks used in 4G (LTE/WiMAX) mobile backhaul. The small but innovative components of this radio allow for super speedy deployment. The design concept focuses on reducing not only CAPEX, but also OPEX. Ideally, in a highly evolved L2/L3 network, the wireless transmission route should be as straightforward as possible, but feature a high capacity and high reliability. iPASOLINK AX makes this evolution possible by providing the necessary functions while removing less-used functions. iPASOLINK AX is also forward compatible and can support MPLS and L3 evolution.
