RF design tools and optimization software help engineers design and analyze radio networks in order to ensure that they meet stringent quality and reliability requirements per ITU and other industry standards.
Gaithersburg, Maryland (PRWEB) August 04, 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 Design Tools– that help engineers to design commercial and public safety land mobile radio systems and microwave networks.
Speaking to the press, Mr. Vijay Kulkarni, CEO of the company said, “RF design tools and optimization software help engineers design and analyze radio networks in order to ensure that they meet stringent quality and reliability requirements per ITU and other industry standards. Some of the important RF design tools are: RF Propagation Studies, Microwave Path Profiles and Intermodulation Interference Studies.”
He explained, “RF propagation is the transmission of radio signals from a transmitter to a receiver. The characteristics of a propagating RF signal largely depends on the radio frequency, geographic terrain, foliage, buildings, and varying weather conditions. Radio network designers would like to predict RF coverage based on a set of proposed system requirements that also include proposed site locations, antennas, and radiating power and other such parameters. Such a prediction helps determine whether the intended service objectives can be met.
Microwave Path Profiles: In designing a microwave link, engineers consider if the terrain/path between two ends of a link is likely to interfere with the propagation. A path profile uses topographical information and Fresnel diffraction impact to plot ground elevation in the path between two microwave sites. Using the path profile tool, antenna placement and its elevation can be determined to provide a line of sight with the desired level of reliability. Computer generated plots help determine a line of sight path, thus avoiding time consuming plots by hand and reducing the need for detailed site surveys. Once a suitable path is established and it has to be verified by "walking the path", or performing a path survey, to ensure that vegetation, buildings, and other obstructions do not interfere with the microwave link path.
Intermodulation interference (IM) is a common cause of interference in radio systems. It may occur when a receiver receives two or more signals at different frequencies. Due to non-linear characteristics of receiver components, in addition to the signal at the desired frequency, undesired signals are produced at frequencies that are sum and difference of the input frequencies. These undesired signals are called IM products. IM analysis should be performed when more than one frequency is transmitted from a platform and whenever new transmit or receive frequencies are added to a platform.”
Mr. Kulkarni further added, “In addition to the above tools, GL has developed, in house, an extensive array of advanced wireless system design tools. They include Geographic Plotting of GPS based data for drive testing and evaluations, microwave Inter-connect, erlang calculator, RF coverage, 2D and 3D terrain maps, service area boundary contours study, TV station Grade-B contour interference analysis, adjacent and co-channels interference analysis, carrier-to-Interferer Ratio Plots.”
