This document discusses high capacity radio link solutions for mobile backhaul. It describes the MINI-LINK portfolio which provides scalable, modular solutions from single hops to aggregation nodes. The solutions support smooth migration from TDM to packet-only networks while maximizing capacity through techniques like adaptive modulation, high order modulation, MIMO, and XPIC. The solutions aim to provide technology leadership with the lowest total cost of ownership through features like high spectral efficiency, small sites, low power consumption, and long equipment lifespans.
