Abstract
A wireless device is capable of communicating within a local area network (LAN) and a personal area network (PAN) concurrently, using a single wireless networking module or circuit. A wireless access point within an infrastructure-based network is used to manage the creation, maintenance, and termination of PANs within the LAN framework.
Claims21
A method comprising:
- providing access and user authentication at a single wireless access point (AP) to a local area network (LAN) via a Wireless LAN (WLAN) to an at least one wireless device upon receiving a LAN access request from a first wireless device;
- determining at a second wireless device that a personal area network (PAN) segment needs to be established;
- transmitting a PAN segment establishment request by the second wireless device directly to the AP wherein communication using the WLAN employs an authentication protocol that is different from the PAN;
- establishing the requested PAN segment at the AP, wherein the PAN segment is active concurrently with the active LAN coverage;
- receiving a PAN segment establishment response from the AP indicating that a PAN segment has been established;
- detecting at the AP a request to join the PAN by at least one other wireless device that is currently in direct communication with AP;
- joining at the AP the at least one other wireless device to the PAN segment;
- and
- transmitting a PAN segment packet directly from the AP to the at least one other wireless device within the PAN segment, the PAN segment packet including a PAN segment ID field identifying the established PAN segment, wherein the PAN segment is different from the LAN.

An apparatus comprising:
- a radio frequency (RF) transceiver subsystem;
- and
- a controller coupled to the RF transceiver subsystem, the controller is configured to:
- provide an active Wireless Local Area Network (WLAN) coverage to at least one wireless device, wherein the apparatus provides access and user authentication to a local area network (LAN) upon receiving an LAN access request from a first wireless device;
- receive a PAN segment establishment request directly from a second wireless device, via the RF transceiver subsystem while actively providing the WLAN coverage, wherein the second wireless device determines that a personal area network (PAN) segment needs to be established;
- establish the requested PAN segment, wherein the PAN segment is active concurrently with the active WLAN coverage and the WLAN employs an authentication protocol that is different from the PAN;
- transmit a PAN segment establishment response to the second wireless device indicating that a PAN segment has been established;
- detect a request to join a PAN from an at least one other wireless device that is currently in direct communication with the RF transceiver subsystem;
- join the at least one other wireless device to the PAN segment;
- and
- transmit directly cause a PAN segment packet from the apparatus to the at least one other wireless device within the PAN segment, via the RF transceiver subsystem, the PAN segment packet including a PAN segment ID field identifying the established PAN segment, wherein the PAN segment is different from the LAN.

An article comprising a non-transitory computer readable storage medium having instructions stored thereon that, when executed by a computing platform, operate to:
- provide an active Wireless Local Area Network (WLAN) coverage to at least one wireless device, wherein a single wireless access point (AP) provides access and user authentication to a local area network (LAN) upon receiving an LAN access request from a first wireless device;
- receive a PAN segment establishment request directly from a second wireless device via an RF transceiver subsystem for the single wireless access point (AP), wherein communication using said WLAN employs an authentication protocol that is different from said PAN;
- establish the requested PAN segment, wherein the PAN is active concurrently with the active WLAN coverage,
- transmit a PAN segment establishment response to the second wireless device indicating that a PAN segment has been established;
- detect a request to join a PAN from an at least one other wireless device that is currently in direct communication with the AP;
- join the at least one other wireless device to the PAN segment;
- and
- transmit directly a PAN segment packet from the AP to the at least one other wireless device within the PAN segment, via the RF transceiver subsystem, the PAN segment packet including a PAN segment ID field identifying the established PAN segment, wherein the PAN segment is different from the LAN.
