A multi-mode WLAN-GSM communications device (100) comprises a WLAN
transmitter (110) that stalls its transmit data and depowers its radio
transmitter whenever a collocated GSM receiver (104) signals it needs to
receive a GSM base-station transmission. If a collocated Bluetooth device
is also included, the Bluetooth receiver can also signal the WLAN
transmitter (110) to be quiet during selected timeslots.
