15Mutual InterferenceProblem: Both IEEE and Bluetooth operate in the same 2.4 GHz ISM Band.Problem: Bluetooth enabled devices will likely be portable and will need to operate in an IEEE WLAN environment.Problem: There will be some level of mutual interference
16Task Group 2 Deliverables Coexistence ModelModel quantifying the effect of the mutual interference of WLAN and WPAN upon one another.Coexistence MechanismsMechanisms or techniques to facilitate coexistence of WLAN and WPAN devices.Both to be documented in an IEEE Recommended Practice
17Coexistence Model The purpose of this Coexistence Model is: To quantity the effect of the mutual interference under varied circumstances.WLAN in Laptop and Bluetooth in nearby PDAWLAN and Bluetooth in the same LaptopTo demonstrate the effectiveness of the adopted Coexistence Mechanism.
18Coexistence Model The Coexistence Model consist of four sections, Physical Layer Models of the and Bluetooth Radios ( )MAC Layer Models of both and BluetoothRF Channel Model of the Radio ChannelData Traffic Models of the traffic over both and Bluetooth networks.
19Coexistence Model Input to the Model Output of the Model Location of and Bluetooth devicesType of Data Traffic flowing over both and Bluetooth networks.Output of the ModelReduction of Network Throughput, for both and Bluetooth.Increase in Network Latency, for both and Bluetooth.
20Coexistence Mechanisms Coexistence Mechanisms Facilitate Coexistence of WPAN & WLAN devicesWe sent out a Call for Submission of Coexistence Mechanisms in September 2000.Presentations are planned forNovember 2000 meeting (last month)January 2001 meeting in Monterey
21Coexistence Mechanisms Collaborative MechanismsSome form of communication between the WLAN and WPAN exists.Use this link to provide fair sharing of medium.Non-Collaborative MechanismsNo communication between WLAN and WPAN exists.Techniques to minimize the effects of the mutual interference
22Task Group 2 Current Status First-order models of and Bluetooth Physical Layers are complete.MAC Layer model for was available. We have added Bluetooth MAC Layer model.We are currently integrating the PHY and MAC Layer Models.
23Task Group 2 Current Status We have received letters of intent from a number of companies to submit their Coexistence Mechanisms.We plan to hear those submissions at the January IEEE meeting in Monterey.We will then evaluate and select a Coexistence Mechanism.
24Task Group 2 Future WorkEnsure proper coexistence of the High-Rate WPAN with both Bluetooth andIssue subsequent releases of IEEE with additional models to include High-Rate WPAN and possibly other wireless devices in the ISM bands

41Low Rate PARTo provide a standard for ultra low complexity, ultra low cost, ultra low power consumption and low data rate wireless connectivity among inexpensive devices. The raw data rate will be high enough (maximum of 200kbs) to satisfy a set of simple needs such as interactive toys, but scaleable down to the needs of sensor and automation needs for wireless communications.The project may also address the location tracking capabilities required to support uses of smart tags and badges.
