Other Fixed or Mobile Wireless Communications Frequency

» Digital cordless phone: The Digital Enhanced Cordless Telecommunications (DECT) standard in Europe defi nes the use of the frequency band 1880 – 1990 MHz for digital cordless phone communication. In the United States, cordless phones use three frequency bands: 900 MHz, 2.4 GHz, and 5.8 GHz, each of which is also intensively used by other short-range wireless communication technologies.

» Global positioning system (GPS): GPS satellites use the frequency bands 1575.42 MHz (referred to as L1) and 1227.60 MHz (L2) to transmit signals.

» Meteorological satellite services: The UHF band from 1530 to 1650 MHz (the L band) is commonly used by meteorological satellites, as well as some global environmental monitoring satellites. Part of the UHF and SHF bands are used for military satellite communication.

» Radio-frequency remote control, such as remote keyless entry systems and garage door openers. These short-range wireless systems, commonly used for automobiles, operate at 27, 128, 418, 433, and 868 MHz in the United States; 315 and 915 MHz in Europe; and 426 and 868 MHz in Japan.
