While the benefits of competing technologies such as the Internet, satellites and television are obvious, the disadvantages of radio communication make it suitable only for certain specific tasks. The frequency of radio waves ranges from 3 kHz to 300 GHz. Is the mention of 16Hz modulation in the Stewart Report significant? This is why commercial radio stations sometimes seem to overlap or blend together, and why Ofcome strictly regulates the use of all publicly owned airwaves. Mountains, hills and rooftops provide inexpensive and accessible bases for microwave transmission towers. As an example the signal may have a . Radio waves are a category of electromagnetic radiation in the electromagnetic spectrum with wavelengths that are longer than infrared light. The SAR limit is set very conservatively in order to ensure the one degree threshold cannot be exceeded. What checks have been done on existing masts? This allows microwave radio systems to transmit thousands of data channels between two points without relying on a physical transmitting medium (optical fibres or metallic cables). Often unclear and is affected by weather. Honda Airwave MS Package price and specification 2010 in pakistan. According to "Electronic Communications System: Fundamentals Through Advanced, 5/e," approximately 35 per cent of all terrestrial communication is maintained by microwave radio relay systems.
