Normally cable channel occupy the 54-550 MHz region in which there is FM radio from 88-108 MHz. To use a cable network for data transmission, we need two key devices: a cable modem (CM) and a cable modem transmission system (CMTS). The CMTS sends a packet to CM, defining its allocated downstream and upstream channels. There are extensive mobile phone and land-line services. applications, operating systems, network card device drivers and networking hardware that enable a system to put a signal on a network cable or out over Wi-Fi or other wireless protocol). PAN may include wireless computer keyboard and mouse, Bluetooth enabled headphones, wireless printers and TV remotes.
