9. doc.: IEEE 802.15-08-0xxx-00-004e Submission March 14, 2008 Huawei, Telecom Italia Slide 9 Information Service Public information service: shopping mall discount information, public news Customized information service: stock market, weather forecast Location based service: tour guide, zone billing Operator Network Operator Network 0101010 Characters: -Portability and Fast association: <1s re-association -Low latency: 1~2s is ok but shorter for single hop – MAC layer latency (<1s) -Broadcast and multicast -Security required -Localization feature

10. doc.: IEEE 802.15-08-0xxx-00-004e Submission March 14, 2008 Huawei, Telecom Italia Slide 10 M-commerce Mobile payment -Payment in the supermarket -Highway toll station -Parking lots Operator Network Operator Network Charging server Characters: -High security: e.g. public key mechanism. Most important requirement -Variable radio range: for different payment scenarios

11. doc.: IEEE 802.15-08-0xxx-00-004e Submission March 14, 2008 Huawei, Telecom Italia Slide 11 File Sharing Sharing data between two devices -File synchronization -Rings or small pictures sharing Characters: -Bulk transfer: tens of KB file transfer in a few seconds (bandwidth increase according to requirements) -Reliability -Peer to peer Address book synchronization Small picture sharing

12. doc.: IEEE 802.15-08-0xxx-00-004e Submission March 14, 2008 Huawei, Telecom Italia Slide 12 Gaming and Chat Ad Hoc gaming/chat Infrastructure-based gaming/chat Characters: -Peer to peer: especially for Ad Hoc mode -Low latency for control messages: <1s -Multicast: users may form a group for the same game or chat topic -Security for multicast Game/chat server

13. doc.: IEEE 802.15-08-0xxx-00-004e Submission March 14, 2008 Huawei, Telecom Italia Slide 13 Telecom Applications Requirements Lower latency: current GTS mechanism is not enough Portability and fast association: association and re-association method should be optimized Peer to peer: not support well in 15.4-2006 yet Broadcast & multicast: current broadcast capability is limited, multicast support is lacked Bulk transfer: the related issues should be considered Enhanced security: e.g. enhanced authentication, public key, multicast security Reliability: packets conflict should be decreased Controllable radio range: power control capability? Localization: it would be a companion feature for many scenarios Various services coexistence: mechanisms to be introduced to make the services peacefully coexist, i.e. one doesn’t impact others much, and flexibly accommodate different service types

14. doc.: IEEE 802.15-08-0xxx-00-004e Submission March 14, 2008 Huawei, Telecom Italia Slide 14 Conclusions TA PTG of ZigBee Alliance is introduced Some telecom applications are introduced Some telecom applications need the MAC layer to be enhanced and optimized
