Abstract
A propagation relay, attached to an enclosure, receives a wireless signal. The signal is sent from a base station over a downlink frequency. The propagation relay converts the downlink signal and transmits it wirelessly, using a different frequency, to mobile station interface ports located within the enclosure. The mobile station interface ports convert the signal back into one at the downlink frequency and send it, via a wireless link, to mobile stations inside the enclosure. Communication from the mobile stations to the base station occurs in the same manner.
Claims30
A propagation system for extending into an enclosure a wireless coverage area provided by a base station located outside of the enclosure, the propagation system comprising:
- a propagation relay, the propagation relay including at least one antenna for transmitting to and receiving from the base station wireless signals in a first set of frequencies, and for transmitting into and receiving from inside of the enclosure wireless signals in a second set of frequencies, and a frequency converter for converting between the first set of frequencies and the second set of frequencies;
- and
- at least one mobile station interface port located in the enclosure, the at least one mobile station interface port including at least one antenna for transmitting and receiving wireless signals in the first set of frequencies and in the second set of frequencies, the at least one mobile station interface port including a frequency converter for converting between the first set of frequencies and the second set of frequencies.
A propagation system for providing wireless communications between at least one mobile station located in an enclosure and a base station located outside of the enclosure, the base station transmitting wireless signals at a first downlink frequency and receiving wireless signals at a first uplink frequency, the mobile station transmitting wireless signals at the first uplink frequency and receiving wireless signals at the first downlink frequency, the propagation system comprising:
- at least one propagation relay, the at least one propagation relay transmitting within the enclosure at a second downlink frequency wireless signals received from the base station at the first downlink frequency, the at least one propagation relay transmitting to the base station at the first uplink frequency wireless signals received from inside of the enclosure at a second uplink frequency;
- and
- at least one mobile station interface port located in the enclosure, the at least one mobile station interface port transmitting at the second uplink frequency wireless signals received from the at least one mobile station at the first uplink frequency, the at least one mobile station interface port transmitting to the at least one mobile station at the first downlink frequency wireless signals received at the second downlink frequency.
A method for providing wireless communications between a mobile station located in an enclosure and a base station located outside of the enclosure, the method comprising:
- receiving wireless signals at a first downlink frequency transmitted by the base station;
- converting the wireless signals at the first downlink frequency into wireless signals at a second downlink frequency;
- transmitting into the enclosure the wireless signals at the second downlink frequency;
- receiving the wireless signals at the second downlink frequency;
- converting the wireless signals at the second downlink frequency into recovered wireless signals at the first downlink frequency;
- and
- transmitting to the mobile station the recovered wireless signals at the first downlink frequency.
