Method and apparatus for band-to-band translation in a wireless communication system
First Claim
1. A wireless communication system comprising:
- a base station with an antenna, the base station configured to predominantly communicate with customer equipment in a first wireless frequency band;
a first translator system having as an input first RF signals located in the first wireless communication frequency band and having as an output second RF signals located in a second wireless communication frequency band;
the antenna coupled for transceiving the second RF signals associated with the translator system;
a remote system including a remote antenna for transceiving the second RF signals associated with the base station, the remote system having a first path and a second path, the first path including a second translator system having as an input the second RF signals, and operable to translate the frequency of the second RF signals to output RF signals located back in the first wireless communication frequency band for communicating with the customer equipment, the second path operable for outputting the second RF signals directly in the second wireless communication frequency band without frequency translation for communicating with additional customer equipment not operating in the first wireless communication frequency band.

Abstract
A translator for translating RF signals from one wireless frequency band to another wireless frequency band in a wireless communications system including a base station, a remote antenna, and remote customer premises equipment. The base station is an existing legacy base station, such as a PCS base station, modified to include a translator for translating RF signals in a first wireless frequency band to RF signals in a second wireless frequency band. The base station transmits RF signals in the second band to a remote antenna, which includes a translator for translating the RF signals in the second band back to RF signals in the first band. The remote antenna may be located in a building or neighborhood with a coverage area as small as a picocell. A CPE (such as a mobile phone) communicates with the antenna in a first wireless frequency band, and the antenna communicates with the base station in a second wireless frequency band.
