Gaithersburg, Maryland (PRWEB) July 31, 2012
GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of its RF Propagation Tool – a Radio Frequency (RF) design tool.
Speaking to the press, Mr. Vijay Kulkarni, CEO of the company said, “Radio propagation studies are important to engineers for planning wireless systems. With applications of WiFi, WiMAX and other wireless technologies becoming more ubiquitous, RF propagation studies have become critical, more than ever, to insure highly reliable networks. For example, one of the key outcomes of an RF propagation study would be prediction of coverage area of a transmitter. It would help a network planner optimize the location of the transmitters to achieve service reliability in a cost effective manner.”
He added, “RF propagation is transmission of radio signals from a transmitter to a receiver. Propagation of RF signals depends on the radio frequency, geographic terrain, foliage, buildings, and varying weather conditions. Radio network designers predict RF coverage based on a set of system requirements that include proposed site locations, antennas, radiating power and various other parameters. Such a prediction is crucial to determine whether intended service objectives can be met.”
Mr. Kulkarni further added, “GL's RF propagation tool supports Cellular, PCS, Land Mobile Radio and other radio network planners in predicting the coverage of their proposed networks or in evaluating the coverage of existing radio systems. RF propagation studies are divided into two categories, Downlink (Talk-Out) and Uplink (Talk-Back) analysis. With inputs such as site locations, antenna types, AGL (Above Ground Level) and AMSL (Above Mean Sea Level), the tool can analyze the links, predict the coverage, and point out deficiencies and dead spots. The tool also provides expected RSSI levels in different regions of coverage.”
