UHF Communication Studies in Urban Areas

Abstract

This project attempts to provide some insight into the nature of UHF communication in urban areas and how communication varies depends on the terrain and obstructions. Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimeter band as the wavelengths range from one meter to one decimeter. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands.

They are used for UHF are FM radio broadcasting, television broadcasting, emergency, business, private use and military. Cell, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. UHF is widely used by public service agencies for two-way radio communication.

The Global Positioning System also uses UHF. The Global Positioning System consists of 24 satellites, which circle the globe once every 12 hours, to provide worldwide position. GPS makes it possible to precisely identify locations on the earth. GPS allows you to record or create locations from places on the earth and help you navigate to and from those places. In the project path UHF communication signal strength are made in urban area-Hyderabad and the results are analyzed and interpreted to understand the UHF Urban area communications and the factors affection communications.
