Comparison of popular LBS tech & PAC <March 2011> 15-11-0194-00-04tv Oct 2011 Comparison of popular LBS tech & PAC GPS/A-GPS/Base station - inaccurate indoor position / need support of operator’s network / local info in server may not be updated timely  Not good user experience NFC - very limited transmission range & discovery capability 802.15 PAC - inaccurate indoor position  no effect on discovery result - good discovery capability  up-to-date and comprehensive local information - independent from operator’s network  easy to implement Slide 4 Betty Zhao etc., Huawei

PAC features for LBS Fully distributed coordination <March 2011> 15-11-0194-00-04tv Oct 2011 PAC features for LBS Fully distributed coordination Peer-to-peer communications - Same as social communication in the real world. Autonomous association Discovery signaling rate: 100kbps Number of devices in discovery: >100 Faster and positive association Two-way discovery - Support sharing more file types, e.g. microfilm, interactive ad Data transmission rate: 10 Mbps - Extend simple one-to-one or one-to-group/all model Group communications: n to m Localization: 10m - Reasonable accuracy Slide 5 Betty Zhao etc., Huawei

<March 2011> 15-11-0194-00-04tv Oct 2011 Chinese LBS market As the popularity of mobile internet and smart phone, the user number of LBS will be increasing as fast as 290.6% between 2010 and 2013. (by iResearch Inc.) There will be estimated 81 million users in 2013. (by iResearch Inc.) How much share of that big market will 802.15 take? Slide 7 Betty Zhao etc., Huawei

<March 2011> 15-11-0194-00-04tv Oct 2011 Questions LBS is a cluster of new applications originated from mobile internet, not mature enough. For LBS, we need to distinguish what functions 802.15 already has and what functions are still needed. There are more interference and less unlicensed bands in the populous areas, heavy usage of LBS may cause delay and affect user experience. Slide 8 Betty Zhao etc., Huawei
