摘要： A method for multiple protocol wireless communications begins by determining protocols of wireless communication devices within a proximal region. The method then continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by, when the protocols of the wireless communication devices within the proximal region are not of a like protocol, selecting a protocol of the protocols of the wireless communication devices within the proximal region based on a protocol ordering to produce a selected protocol. The method continues by utilizing the selected protocol by the wireless communication devices within the proximal region to set up a wireless communication within the proximal region.

摘要： A method and apparatus for dynamic frequency selection in a wireless communication system or network includes processing that begins when an access point determines interference on a wireless channel that is being used by the access point. When the interference exceeds an interference threshold, the access point provides a request packet to affiliated stations being serviced by the access point for channel spectrum information. The processing continues as the affiliated stations generate the channel spectrum information regarding each of the wireless channels in the wireless communication network. The processing proceeds then as the affiliated stations provide the channel spectrum information to the access point via the current wireless channel. The access point interprets the channel spectrum information to determine a desired wireless channel of the plurality of wireless channels within the wireless communication network. The access point then provides a selection packet to the affiliated stations via the current wireless channel to indicate that the access point will begin using the desired wireless channel at a particular future time.

摘要： An integrated circuit radio transceiver and associated method comprises a multi-mode device operable to support personal area network communications as well as traditional wireless local area network communications. In one embodiment, IEEE 802.11 protocol IBSS communications are used to transport Bluetooth communication data packets. In another embodiment, a direct link comprising direct packet transfers without beaconing is performed between the multi-mode device and another multi-mode device. Thus, the multi-mode device is operable to establish traditional BSS communications with an Access Point in addition to establishing peer-to-peer communications with another multi-mode device to transport the Bluetooth communications over the 802.11 IBSS communication link or over an IEEE 802.11 direct communication link.
