Patent ID: 6973304

Claim:
An allocation device which communicates with a local base station by radio and comprises a shared antenna, a frequency division multiplexer, and a link unit, and is configured so that: said shared antenna is configured to receive a shared frequency band of radio signals radiated from said local base station, said shared frequency band including different shared frequency bandwidth portions, each different shared frequency bandwidth portion being associated with a different service, each different service being associated with a separate service frequency band; said frequency division multiplexer is configured to division-convert the shared frequency band of radio signals received by said shared antenna into plural kinds of signals in respective frequency bands which do not overlap with one another and which each correspond to a different separate service frequency band; and said link unit is configured to link to external receivers that are associated with the different services to send the plural kinds of signals in the respective frequency bands which do not overlap with one another and which each correspond to a different separate service frequency band to each said external receiver as a signal in a frequency band corresponding to the different separate service frequency band associated with each said external receiver.
