Abstract
A transceiver capable of handling both UWB and narrowband calls includes a mechanism for detecting when a signal from one of the narrowband systems will interfere the UWB communication and switching the UWB data connection link to the alternative data path.
Claims46
A system for transmitting and receiving data over a wireless interface, the system comprising:
- an ultra wide band (UWB) transceiver for transmitting and receiving radio frequency (RF) radiation along a path through an original channel in an UWB band;
- at least one narrowband transceiver for transmitting and receiving RF radiation in at least one RF band having potential to cause interference with at least a portion of the original channel;
- and
- data shifting means for shifting UWB data from said original channel to an alternative path when UWB link quality of the original channel decreases below a threshold value, the alternative path predetermined to be less affected than the original channel to interference caused by operation of the at least one narrowband transceiver.
A method for transmitting and receiving data over a wireless interface, the method comprising:
- passing ultra wide band (UWB) data through a path through an original channel in an UWB band;
- communicating RF radiation in at least one RF band having potential to cause interference with at least a portion of the original channel;
- shifting said UWB data from said original channel to an alternative path when UWB link quality of the original channel is less than a threshold value, the path predetermined to be less affected than the original channel to the interference caused by the communication in the at least one RF band;
- and
- communicating said UWB data through the alternative path.
An article of manufacture comprising a program storage medium readable by a computer, the medium embodying instructions executable by the computer for performing the operations of:
- passing ultra wide band (UWB) data through a path through an original channel in a UWB band;
- communicating RF radiation in at least one RF band having potential to cause interference with at least a portion of the original channel;
- shifting the UWB data from the original channel to an alternative path when UWB link quality of the original channel is less than a threshold value, the path predetermined to be less affected than the original channel to the interference caused by the communication in the at least one RF band;
- and
- communicating the UWB data through the alternative path.
An apparatus comprising:
- means for passing ultra wide band (UWB) data through a path through an original channel in a UWB band;
- means for communicating RF radiation in at least one RF band having potential to cause interference with at least a portion of the original channel;
- means for shifting the UWB data from the original channel to an alternative path when UWB link quality of the original channel is less than a threshold value, the path predetermined to be less affected than the original channel to the interference caused by the communication in the at least one RF band;
- and
- means for communicating the UWB data through the alternative path.
A device for transmitting and receiving data over a wireless interface, the device comprising:
- an ultra wide band (UWB) transceiver adapted to communicate radio frequency (RF) radiation in at least one of a plurality of UWB bands, the at least one channel comprising an original path, the at least one UWB band carrying UWB data;
- at least one narrowband transceiver adapted to communicate RF radiation in at least one RF band, the at least one narrowband transceiver known to cause interference with the at least one UWB band when the at least one narrowband transceiver performs at least one communication operation of transmitting and receiving;
- and
- at least one data processing unit adapted to determine that the at least one communication operation is occurring and in response to the occurrence of the at least one communication operation is adapted to shift the UWB data to an alternative path.
