Summary:A method is provided for reducing the search space of an acquiring ultra wideband (UWB) device seeking to join an UWB communication system, such as a Multi-band orthogonal frequency divisional multiplexing (OFDM) UWB system, by providing wireless network information, such as the hopping pattern or Time-Frequency Code (TFC), timing and frequency information to the acquiring UWB device. The wireless network information is provided using a short range wireless module such as Bluetooth that may coexist with a UWB device. For example, an assisting UWB device, via a short range Bluetooth device module, may convey initial synchronization information, to the acquiring UWB device that also may have a coexisting UWB module. By knowing the TFC, timing and frequency information the acquiring UWB device may know the approximate beginning of the superframes of the UWB devices in the UWB communication system which may help reduce power consumption and probability of false alarm.
