Local Multipoint Distribution Service (LMDS)
This is a survey paper on LMDS. With a introduction on LMDS and then a discussion on fixed wireless networks, this paper looks into different ways fixed wireless communication can be achieved and then gives a brief description on the various broadbands available for communication. It also discusses technical and design issues involved with LMDS. See also: Other Reports on Recent Advances in Net...
متن کاملLocal Multipoint Distribution System (LMDS)
As a result of the propagation characteristics of signals in this frequency range, LMDS systems use a cellular-like network architecture, though services provided are fixed, not mobile. In the United States, 1.3 MHz of bandwidth (27.5 B 28.35 GHz, 29.1 B 29.25 GHz, 31.075 B 31.225 GHz, 31 B 31.075 GHz, and 31.225 B 31.3 GHz) has been allocated for LMDS to deliver broadband services in a point-t...
متن کاملRecommendation on Channel Propagation Model for Local Multipoint Distribution Service
Abstract We recommend a flexible channel propagation model, which includes no more than three taps and has flexible tap gains and tap delays. The tap gains have a progressive decrease relationship, while the tap delays have a progressive increase one. The model is valid under the following assumptions: (1) there is line-of-sight propagation, (2) highly directional antennas are used at least at ...
متن کاملClassification of Statistical Channel Models for Local Multipoint Distribution Service Using Antenna Height and Directivity
Abstract The antenna height and directivity are used in the classification of statistical channel models for local multipoint distribution service (LMDS). When directional antennas are used and the antennas are sufficiently high providing a line-of-sight (LOS) propagation path between the transmitter and receiver, the statistics of the radio channel can be described by the lognormal or Nakagami...
