Paratek To Launch Multi-Beam, Electronically Scanning Antenna For GSM/GPRS and EDGE at 3GSM WORLD CONGRESS.Business Editors/Hi-Tech Writers COLUMBIA, Md.--(BUSINESS WIRE)--Feb. 15, 2002 Paratek Microwave, Inc., a manufacturer of electronically tunable components and scanning antennas for wireless original equipment manufacturers and service providers, will premiere the DRWiN(TM) (Dynamically Reconfigurable Wireless Networks) GSM (Global System for Mobile Communications) A digital cellular phone technology based on TDMA that is the predominant system in Europe, but also used worldwide. Developed in the 1980s, GSM was first deployed in seven European countries in 1992. antenna at the 3GSM World Congress, (Stand G17, Hall 2) in Cannes, France (February 19 - 22, 2002). DRWiN GSM is the first antenna to support GSM, GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations. and EDGE with a simple interface into the base station. It uses analog phase shifters to produce multiple simultaneous beams, independently steerable in each time slot Continuously repeating interval of time or a time period in which two devices are able to interconnect. . These phase shifters are made from Paratek's revolutionary Parascan(TM) materials technology. President and chief executive officer Ali Pourtaheri explains, "Instead of pursuing the traditional approach of digital beam forming, Paratek has developed the DRWiN antenna which forms beams in the RF domain. Studies have shown that the cost-to-performance advantage of this solution far exceeds any existing smart antenna Smart antenna (also known as adaptive array antennas, multiple antennas and recently MIMO) refers to a system of antenna arrays with smart signal processing algorithms that are used to identify spatial signal signature such as the direction of arrival (DOA) of the signal, and use solution in the market. Furthermore, the beam controller of the DRWiN GSM antenna reduces integration risk to the network operators. Operators will have a strong business case for incorporating the DRWiN GSM antenna into their networks." Unique DRWiN GSM Antenna Advantages -- Delivers greater than 21 dBi of receive gain and greater than 18 dBi of transmit gain -- Provides 50% greater coverage for a greenfield installation -- Supports multiple (up to 24) independently steerable narrow beams with selectable beamwidths -- Increases Carrier-to-Interference Ratio by 10 dB -- Improves frequency reuse from 9 to 4 and doubles the capacity -- Lowers cost and risk of integration with existing base stations About DRWiN(TM) GSM Antenna The DRWiN GSM antenna consists of a receive (RX) antenna panel, multiple transmit (TX) antenna panels and a multi-beam controller (MBC (Multimedia Benchmark Committee) A graphics benchmark that provides MPEG-2 and other tests. See GPC. ). This design supports up to 12 carriers with dual polarization, providing polarization diversity. The width of each RX beam can be adjusted. The transmit antenna consists of multiple antenna panels (up to six per sector), each panel capable of providing two orthogonally or·thog·o·nal adj. 1. Relating to or composed of right angles. 2. Mathematics a. Of or relating to a matrix whose transpose equals its inverse. b. polarized A one-way direction of a signal or the molecules within a material pointing in one direction. , electronically scanning beams and a single, fixed sector beam. The two scanning beams are designed to support two independent carriers and the single sector beam provides full sector coverage for the GSM control channel. The MBC controls the beam directions of the RX and TX antennas as well as the RX beamwidths through an interface with the base station. Information such as framing and frequency-hopping schedules are provided to the MBC to compute the angle to point the beams at the appropriate customer.
