Terms 2 Terms Abis Interface between the BTS and the BSC, and between BTSs. Alarm Announcement given to the operating personnel about abnormal functioning of the system, a failure, or an indication of the degradation of the service level or reliability. Alarm Status The current status of the system. Indicates what alarms are active, if any. Backplane Connector board to which the plug in units are connected in the MetroSite BTS, MetroHub and MetroSite BBU. Located at the side of the cabinet.
Glossary Commissioning Tasks performed in order to enable the BTS to be connected to the network. Includes operational tests and configuration of the transmission equipment. Coverage Area see Cell. D-bus Bus between TRXs and transmission units (D1), and for internal communication between the units of the MetroSite BTS (D2). Downlink Diversity The BTS swaps two transmitters on a single channel to obtain improved overall sensitivity in a system which is subject to random fading. See Uplink Diversity.
Terms Macrocell Macrocell applications cover large areas with a cell radius of 1 - 10 km (0.6 - 6 miles). The large coverage area is achieved by means of installing the antenna high up off the ground. See Microcell . Microcell Microcell applications typically cover areas ranging from 100 m to 1 km (330 feet to 0.6 miles). The antennas are installed under the rooftop level. See Macrocell.
Glossary Nokia Smart Radio Concept A Nokia solution for gaining the maximum benefits of EDGE by optimizing the radio link performance with Nokia EDGE base stations. Nokia Q1 Communication protocol used on Q1-buses. Operator A telecommunications company running telecommunications services in a geographical area. PCM time slot 2 Mbit/s PCM circuit is divided into 32 64 kbit/s time slots. 1.5 Mbit/s PCM circuit is divided into 23 64 kbit/s time slots. Point-to-point Transmission between two fixed points.
Terms UL (Uplink) The direction of transmission in which the mobile station is the transmitting facility and the BTS is the receiving facility. Uplink Diversity The BTS uses two antennas and two receivers simultaneously on a single channel to obtain improved overall sensitivity in a system which is subject to random fading. See Downlink Diversity.
