Abstract The invention defines a combined and harmonized protocol for wireless LANs based on the combination of ETSI BRAN HiperLAN/2 protocols with IEEE 802.11 a protocols. The new HipeLAN/2 enhanced AP (H/2eAP) will—in addition to its standard HiperLAN/2 operation— also work as Point Coordinator of 802.11 a, or is supported by a cooperative Point Coordinator of 802.11. The H/2eAP sends a corporate beacon at the H/2 Target Beacon Transmission Time (H/2 TBTT) with setting the CfpDurRemaining parameter to (a multiple of) 2 ms. Upon receiving this beacon by stations of the 802.11 a BSS, the stations recognize it as a foreign BSS beacon, extract and evaluate the CfpDurRemaining parameter and thus set timers to the appropriate duration, not to initiate any data transmission during the respective time. After sending this beacon the H/2eAP is able to initiate the transmission
