A method and signal therfor embodied in a carrier wave for sending information from transmit stations to receive stations over a transmission medium of a frame-based communications network. The information is sent in transmit frames having a frame format comprising a fixed rate header, followed by a variable rate payload, followed by a fixed rate trailer. The fixed rate header includes a preamble. The preamble has a repetition of four symbol sequences for facilitating power estimation, gain control, baud frequency offset estimation, equalizer training, carrier sensing and collision detection. The preamble also includes a frame control field. The frame control field has scrambler control information for frame scrambling initialization, a priority field to determine the absolute priority a transmit frame will have when determining access to the transmission medium, a payload encoding field which determines constellation encoding of payload bits in the variable rate payload, and a header check sequence for providing a cyclic redundancy check. The variable rate payload is transmitted pursuant to dynamic adjustable frame encoding parameters for improving transmission performance for a transmit frame being transmitted from a transmitting station to a receiving station. The header also includes a destination address field, a source address field and an ethertype field.

A method for interoperability of a network interface protocol with an Internet interface protocol begins by receiving a scan channel request of a plurality of channels that are in accordance with the network interface protocol. The method then continues by determining whether an Internet packet is being received via one of the plurality of channels when the channel scan request is received (i. e. , is a higher layer protocol supporting a current transmission). If so, the method continues by scanning at least one channel of the plurality of channels, but does not scan all of the plurality of channels at one time. The method continues after the scanning by tuning to the channel supporting the higher layer protocol communication to transmit at least one outbound Internet packet. The method then continues by scanning at least another channel of the plurality of channels.

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. 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.

A wireless interface circuit transceives packetized data between a host module and a first external device using a frequency spectrum, wherein the packetized data is formatted in accordance with a first wireless communication protocol and wherein the packetized data includes a request from the first external device to use at least a potion of the frequency spectrum for communication via a second wireless communication protocol. A coexistence management module generates a wireless interface schedule that includes a least one contention free period reserved for communication via the second wireless communication protocol, and generates schedule data, based on the wireless interface schedule, for transmission to a plurality of external devices including the first external device.

Aspects of a method and system for bridging and routing offload in a multiport wireless system are presented. Various aspects of the system may include a wireless network interface subsystem that enables transcoding of at least a portion of a data packet received by the wireless network interface subsystem. The wireless network interface subsystem may enable transfer of the transcoded portion of the data packet from the wireless network interface subsystem to a wired network interface subsystem that is communicatively coupled thereto. The transcoded portion of the data packet may be compliant with a format utilized by the wired network interface subsystem.

Certain aspects of a method for enabling exchange of information in a secure communication network may comprise encapsulating authentication enablement information comprising data for configuring at least one 802.11 client station. One or more 802.11 client stations may be configured without disrupting access to any other 802.11 client station that is already communicatively coupled to the network. The encapsulated authentication enablement information may be authenticated using an extensible authentication protocol (EAP).
