ABSTRACT

Local Multipoint Distribution Service (LMDS) is the broadband wireless point-to-multipoint communication system operating above 20 GHz that can be used to provide two-way voice, data, video services and Internet. Services using LMDS technology include high-speed Internet access, real-time multimedia file transfer, and remote access to corporate local area networks, interactive video, video-on-demand, video conferencing, and telephony among other potential applications. My paper gives a general idea about LMDS, its architecture and applications.
The architecture part mainly deals with the equipments used in base station and customer premise. In the United States, 1.3 MHz of Bandwidth have been allocated for LMDS to deliver Broadband services in a point-to-point or point-to-multipoint configuration to residential and commercial customers. The LMDS has wide range of applications in wireless LAN, Broadband Wireless Local Loop and mainly transmission of video, voice and Internet. As a transport system LMDS can be engineered to provide 99.999 percent availability.
