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.

6. The method of claim 1, wherein:

the at least one other wireless device within said PAN segment is not included in within the LAN.

7. The method of claim 1, wherein:

said AP is included within said PAN segment and within the LAN.

8. 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.

9. The apparatus of claim 8, wherein:

said apparatus can maintain a connection to said LAN at the same time that it is part of said PAN segment.

10. The apparatus of claim 8, wherein:

the said apparatus can communicate within the LAN and the PAN segment using a common wireless networking module using the same wireless standard.

11. The apparatus of claim 8, wherein:

said apparatus and said AP are each configured in accordance with an IEEE 802.11x wireless networking standard, wherein said PAN segment packet is an IEEE 802.11x packet that is modified to include said PAN segment ID field.

12. 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.

13. The article of claim 12, wherein:
