May, 2000 doc. : IEEE 802. 15 -<doc#> Who we are • Bluetooth Special

May, 2000 doc. : IEEE 802. 15 -<doc#> Who we are • Bluetooth Special Interest Group (SIG) is a group of 9 Promoter Companies and over 1800 Adopter Companies committed to seeing Bluetooth be a ubiquitous, easy to use, wireless connectivity tool. • The SIG has Working Groups which are charged to investigate areas of interest, draft working models, and draft specifications. • The Working Groups are staffed by people from the 9 promoter companies and (in the future) by a select number of representatives from Associate Members in some of the Working Groups.

May, 2000 doc. : IEEE 802. 15 -<doc#> Coexistence Working Group Charter · Work

May, 2000 doc. : IEEE 802. 15 -<doc#> Coexistence Working Group Charter · Work within the Bluetooth™ community as well as with cross industry groups (e. g. IEEE) to quantify the detrimental effects which Bluetooth™ and other wireless products will have on the performance of both. This information will be imperative for members of the Bluetooth community to advise their customers of the realistic performance one can expect in different environments as well a build products which span between Bluetooth™ and other wireless products. In addition, it will be used to disseminate SIG sponsored information on issues of coexistence to regulatory bodies. · Develop methods of Bluetooth™ operation that will be used to improve coexistence between systems in the shared radio band. These will be issued as Best Practices white papers, improvements to the Bluetooth™ specifications, or formal profiles as necessary. · To work closely with the Radio 2. 0 Working Group to evaluate coexistence issues in new proposed radio designs.

May, 2000 doc. : IEEE 802. 15 -<doc#> Areas we will investigate(1) • Performance

May, 2000 doc. : IEEE 802. 15 -<doc#> Areas we will investigate(1) • Performance impact when Bluetooth and another device are operating in the 2. 4 GHz band. Environments: Interfering systems: • General Residential • Apartment Building • Business, closed office • Business open/cubical office • Airport, Shopping Mall, factory floor • Outdoors Submission • Bluetooth • 802. 11 Frequency Hop • 802. 11 CCK • Home. RF • NPRM Home. RF Proposal • DECT • Microwave Ovens • etc. 5 Tod Sizer, Lucent Technologies / Bell Laboratories

May, 2000 doc. : IEEE 802. 15 -<doc#> Areas we will investigate(2) • Develop

May, 2000 doc. : IEEE 802. 15 -<doc#> Areas we will investigate(2) • Develop Best Practices to optimize coexistence – Special case: Bluetooth and another WLAN standard in the same enclosure. • If additions/changes in the Bluetooth specification can make a significant difference in coexistence, this will be proposed as a Bluetooth Profile. • Work with the Radio 2. 0 group who are charged with looking at higher rate radio options. Our work will ensure that coexistence issues are in the forefront when architectures are developed. Submission 6 Tod Sizer, Lucent Technologies / Bell Laboratories

May, 2000 doc. : IEEE 802. 15 -<doc#> Areas we will not investigate •

May, 2000 doc. : IEEE 802. 15 -<doc#> Areas we will not investigate • Implementation specific issues – will make the job unmanageable. – Hopefully will not make a significant impact on the conclusions of our studies. – Several companies ARE developing simulations based on their particular implementation and can be used to check with the WG general results. Submission 7 Tod Sizer, Lucent Technologies / Bell Laboratories

May, 2000 doc. : IEEE 802. 15 -<doc#> Progress to date • Met Face-to-Face

May, 2000 doc. : IEEE 802. 15 -<doc#> Progress to date • Met Face-to-Face in April, since then weekly by teleconference • Have agreed to use Matlab as the common simulation platform. • Now developing assumptions to be used in simulations - e. g. fading statistics, path loss models. • First simulation results are imminent.
