Coverage enhancement methods for LMDS.

Coverage enhancement methods for LMDS.

The upper SHF and EHF radio bands (above about 20 GHz) offer abundant available bandwidth for access to metropolitan area networks by fixed broadband wireless access (FBWA) systems. However, these systems must withstand significant propagation impairments, especially shadowing by obstacles and rainf...
