WebUsers can send data through a subchannel by modulating it on a carrier wave at the subchannel's frequency. It is used in satellite communication systems and telephone trunklines. FDMA splits the total bandwidth into multiple channels. Each ground station on the earth is allocated a particular frequency group (or a range of frequencies). chehaw state park albany gaWebBitPim is a cross-platform, open source application for managing data on cell phones that use the CDMA mobile telephony protocol .
