rbs 2106 and rbs 2206 radio configurations 3 definitions tower mounted amplifier (tma) the tma compensates for signal loss in the receiver antenna cables, reduces system noise and improves uplink sensitivity. the tma can consist of a duplex filter. duplex is the function that allows communication in two directions (sending and receiving) on one channel. the tma used for 12 trx products is dual duplex tma (ddtma). some configurations can use a tma designed for reception only (rtma). antenna reference point the antenna reference point is the point where the radio signal crosses the rbs border, that is, the connector for the antenna feeder. see the figure below. note: the tma is inside the rbs border. +'/ # %$%&' 1 2 -&) # 3&*)&2&)&!&(+ &* fi gure 3 antenna reference point antenna system the antenna system is constituted by all rf transmission and reception a ntennas, directed to cover the same area or multi-casting configurations. antenna sharing unit (asu) an asu is used for sharing rx antennas between rbss. 5(58) en/lzt 720 0318 uen r2a free datasheet http://
rbs 2106 and rbs 2206 radio configurations base transceiver station (bts) a bts is a unit operating on a set of frequencies in one cell. basic configuration a basic configuration is a specified set of transceivers, cdus, and in some cases, tmas, connected to one antenna system. a basic configuration can be multiplied or used in combination with other basic configurations to build the needed site equipment. variations of a basic configuration may exist, differing in cable lengths. this depends on factors such as implementation in different cabinets. radio base station (rbs) an rbs is all equipment in an ericsson base station, and may be comprised of several btss. each rbs has one dxu, controlling a maximum of 12 trxs. site cell configuration (scc) the scc is a geographical concept describing how an area around one rbs site is divided into radio traffic areas. the following types of site are defined: omni-site radio coverage in one 360 degree sector, that is in one area, using one bts. 2-sector site radio coverage in two sectors, that is two distinct areas, using two btss. 3-sector site radio coverage in three sectors, that is three distinct areas, using three btss. 3.1 cabinet types rbs 2106 outdoor cabinet with a maximum of six dtrus/12 trxs per cabinet rbs 2206 indoor cabinet with a maximum of six dtrus/12 trxs per cabinet 6(58) en/lzt 720 0318 uen r2a free datasheet http://

rbs 2106 and rbs 2206 radio configurations 8.2 one duplex antenna rx/tx the tdma rbs may be equipped with only one tx/rx antenna. the recommendation in this case is to add two antennas for the dtru based rbs. one rx signal from the dtru based rbs is supplied to the tdma rbs, thus adding rx diversity to the tdma rbs. b +

rbs 2106 and rbs 2206 radio configurations 8.4 one rx and one duplex antenna if the original antenna arrangement is tx/rx + rx, the recommendation differs for configurations where the duplex filter is mounted internally, without the possibility to access the tx and rx ports separately, and configurations where therxpathisaccessible. internal duplex filter if the duplex filter is internal and the rx path is not accessible, the recommendation is to add one antenna and rebuild the configuration in the same way as in the case with tx + rx + rx in section 8.1 on page 51 . bb +

% & *%& figure 22 internal duplex filter a special case is where only one tx/rx and one rx port are accessible from the outside of the cabinet. in that case the solution stated below can be used. note that the three duplex filters in series (one internal and two external) will degrade the tx performance of the co-sited rbs. 55 ( 58 ) en/lzt 720 0318 uen r2a free datasheet http://
