Abstract
A wireless device, for use in an ad hoc network and a communication system therefor having ad hoc networks feature one or more such devices having a transceiver including a receiver portion which simultaneously correlates (33, 34 in FIG. 3) an access code of an incoming data packet against that associated with plural wireless protocol versions, supported by that wireless device (BT), in a manner permitting a linkup between that wireless device and any of the other devices, the other devices including ones which are programmed to correlate against any single one of the protocol versions, as well as ones which are programmed to simultaneously correlate against the referred-to plural protocol versions. As an example, the receiver portion employs as many parallel-connected correlators as are the number of wireless protocol versions such wireless device supports simultaneously. There is also featured a method for facilitating an ad hoc connection between different ones of plural wireless transceiver devices which are supported by different protocol versions.
