November 1999 M68333 Rev. A Tel-Link PMP - Sector Terminal Installation & Maintenance Manual 2-12.0 Sector Terminal OverviewThe PMP network is composed of one or more base stations that are strategically located within the desiredcoverage area (refer to Figure 2-1). Base Station/Sector Terminals are located at the center of each celland have a radius of up to 10 Km depending on the RF frequency, climate type, desired network availabil-ity, line-of-sight profiles, and traffic capacity requirements. The Base Station consists of 1 to 24 Sectors. Asectorized area of a Base Station/Sector Terminal is supported by 1 to 5 Sector Indoor Units (IDUs),depending on the number of Remote Terminals located in that sector. Each Sector communicates directlywith the Remote Terminal within a sector area of 22.5° to 90° of coverage within the 360° area around thebase station. Each base station also interfaces to the Public Switched Network (PSN) through a high-speedbackbone link. Figure 2-1 - Example of Simplified Base Station SiteThe system utilizes an ATM cell-multiplexed, continuous carrier to transmit data from the base station to theRemote Terminals. Each sector uses one or more downlink carriers to deliver these cells to the RemoteTerminals. These carriers are transmitted at different frequencies to avoid interference. Either a FDMA orTDMA scheme is used by the Remote Terminals to transmit information to the Base Station. When FDMAuplinks are used from the Remote Terminals, each Terminal communicates on a separate frequency chan-nel with a demodulator at the Base Station for each channel. When TDMA uplinks are used from theRemote Terminals, multiple remotes share a single carrier by transmitting in designated time slots.
