w <br />t.' <br />1^- <br />L <br />Ceiluiar <br />Glossaiy <br />Cell. A smaU geographic area served by a <br />low-powered transmitter. 2 to 10 miles in <br />radius. <br />Cell Site. An instailation containing the <br />Transmitters, receivers and control equip­ <br />ment necessary to connect the cellular <br />phone system and the conventional wireline <br />Tciephone network. <br />Cell Splitting. The division of a larger ceil <br />i.atc several smaller ceils to provide more <br />channels within the same geographical area, <br />.ind therefore provide belter .service. <br />Ceiluiar Geuf^rupiiicai Service .Area <br />tCGS.A). A specific geographic area, <br />viipan which a ccilmar system serves ,;ns- <br />.vjmeri. Mobile cu.'lemers are expected to <br />subscribe to cellular service within a civen <br />CGSA. <br />Digital Radio Link. .A radio signal used to <br />connect telephone circuits from a cel! site to <br />the central switching equipment (the <br />MTSO). <br />"nmic Switching System. A computer <br />i lUtomatically routes calls within the cel- <br />luiar system, located at a central .site. <br />Hand-OIT. The automatic switching of a <br />signal from one cell to another, which (veurs <br />within u fraction of a second. <br />Mobile Telephone Switching Office <br />(MTSO) Also known as the MTX or <br />"Switch". The interface between the cell <br />sites ad the cor.veniional wireline tele­ <br />phone network. It serves as the central co ­ <br />ordinator and controller, as well fs housing <br />the switching equipment for a cellular tele* <br />phone system. <br />Radio Common Carrier (RCC). Firms <br />licer^^ed by the Federal Communications <br />Commission (FCO to provide a variety of <br />radio services to the public, including dis­ <br />patch and paging services. .Many RCC's now <br />own cellular licenses. US WEST New Vector <br />is an RCC licensed bv the FCC. <br />Roaming. Tac .ibility to operate a cellular <br />mobile telephone in a mobile service area <br />other than Lhe one from which .service is <br />subscribed ■ for e.\ample, being able to use <br />your cellular phone in Minneapol- <br />though you subscribed originally i;. <br />Sectoriiation. An engineering refinement <br />of a celFs transmission antennas, which im­ <br />proves call quality by reducing cross­ <br />talk/interference. This is done by splitting <br />the coverage of the cell site into three equal <br />sectors, by means of directional antennas. <br />Wireline Telephone Network. The con­ <br />ventional local telephone network which <br />transmits calls over wires rather than radio <br />waves The FCC has ruled that wireline <br />companies or their uffUiates may apply for <br />cellular licenses in those areas w'here they <br />currently provide wireline service.
