IEEE P802.15 Working Group for Wireless Personal Area Networks July 8, 1999 IEEE P802.15 Working Group for Wireless Personal Area Networks Coexistence and Interoperability Study Group Steve Shellhammer, Symbol Technologies

The Importance of Coexistence July 8, 1999 The Importance of Coexistence Coexistence of 802.15 WPAN and 802.11 WLAN was mandated by the 802 Executive Committee. It is likely that WPAN and WLAN devices will operate in the same ISM band. WPAN devices are likely to operate in locations where WLANs are installed. Steve Shellhammer, Symbol Technologies

The Importance of Interoperability July 8, 1999 The Importance of Interoperability It is important that two devices that conform to the 802.15 standard interoperate with one another at the Physical Layer. It may also be desirable to have WPAN and WLAN devices interoperate at some higher layer. Steve Shellhammer, Symbol Technologies

July 8, 1999 Proposal We propose the formation of a Coexistence and Interoperability Study Group. The Study Group would write a Project Authorization Request (PAR) defining the objectives and scope of the Coexistence and Interoperability Task Group. The Study Group would exist from July 1999 to November 1999. Steve Shellhammer, Symbol Technologies

July 8, 1999 Coexistence There are many devices with which a WPAN must coexist. The following is a partial list. 802.11 1 & 2 Mbps FHSS 802.11 1 & 2 Mbps DSSS 802.11 5.5 & 11 Mbps DSSS Other 802.15 WPAN devices, of potentially a different type. Steve Shellhammer, Symbol Technologies

Potential deliverables of the Task Group July 8, 1999 Potential deliverables of the Task Group A series of reports describing the impact of a WPAN on a WLAN in the same vicinity, and visa versa. A set of recommended practices for both the WPAN and WLAN to maximize coexistence Possibly, some recommended modifications or extensions to the WPAN and/or WLAN standards to improve coexistence. Steve Shellhammer, Symbol Technologies

Interoperability There are many levels of interoperability July 8, 1999 Interoperability There are many levels of interoperability 802.15 to 802.15 devices (PHY layer) 802.15 to 802.11 devices (higher layer) The Study Group will define what type of interoperability to address as a Task Group. Comments from the WG? Steve Shellhammer, Symbol Technologies

July 8, 1999 Liaison with 802.11 It seems likely that the Task Group would likely set up a liaison with 802.11 to facilitate communication on the topics of coexistence and interoperability. Steve Shellhammer, Symbol Technologies

July 8, 1999 Study Group Schedule Start to think about what to include in PAR over the next two months. I will send out material via email. Complete PAR at Santa Rosa. At Santa Rosa we will decide if we should include Interoperability. Task Group work starts in Hawaii. Steve Shellhammer, Symbol Technologies
