Radio Transmitters |
The frequency spectrum is divided into segments for specific use. These frequency allocations are determined by international organisations (eg World Administrative Radio Conference), and may vary slightly between large geographical regions. For example, in the UK the FM broadcast band is in the range 88-108MHz, while in parts of Eastern Europe it extends down to 76MHz. In urban environments, the electric field strength due to radio transmissions may be around 200mV/m. A few selected examples from the frequency spectrum are :
