Abstract
A wireless device includes a baseband unit and front-end units that are provided in individual housings. The baseband unit and the front-end units are connected to each other by wire. A transmitter for synchronization that converts a signal based on a reference clock into a radio signal and transmits the radio signal as a clock synchronization signal is provided in any one of the housings, and receivers for synchronization that receive the signal for the clock synchronization and PLLs that generate a clock synchronized with a reference clock signal which is obtained from the received clock synchronization signal are provided in the housings other than the housing having the transmitter provided therein. In order to simultaneously process a plurality of wireless devices having different symbol rates, it is preferable to provide the transmitter, the receiver, and the PLL for each reference clock.
