28 GHz Local Multipoint Distribution Service (LMDS): Strengths and Challengessystem design information was gathered from the FCC Negotiated Rulemaking Committee (NRMC) on co-frequency sharing in the 28 GHz band between LMDS and satellite services. This paper also describes some of the challenges that face LMDS such as a “fragile” propagation environment. The results of a pro

PCS System Design Issues in the Presence of Microwave OFSe study is provided to exemplify the discussed supposition that microcell (base stations well below the surrounding buildings clutter with low transmitter power) system design minimizes microwave OFS interference and their immediate relocation. Practical interference calculations between different w

Performance of RSS-, SIR-based Handoff and Soft Handoff in Microcellular Environmentsn reduce the handoff rate by 50% with the same signal quality as compared to the RSS-based scheme. For the RSS-based, and the SIR-based handoff schemes, the corner effect limits the maximum allowed speed around the corner for a given signal quality due to signal outages in the uplink. The receiver d
