ZigBee Information Services� ZigBee network covers a

commercial area as CommercialCenter or high densityentertainment areas (e.g. shopsand pubs)

� ZigBee nodes has information (orpoint to remote information)about the shops and activepromotion: updated informationare distributed by a managementplatform

� Users with a Mobile terminal withan integrated ZigBee node (onterminal, SIM or on MMC/SDIO)can customize their tour in thearea selecting shops to visit andreceiving an optimized path

� Selected Shops can point outtheir presence when a userapproaches them

•Reduced cost compared with RFID readers (1%)

•Extended range compared to NFC

Zone Billing concept

�Shops might have special conventions with telco operators

�Whenever staying in the shop or mall area the operator can pro vide specialoffers and/or discounts (location-based services)

�SMS or call promotions can be offered to people waiting in spe cial location(e.g. waiting in unpleasant queues or staying in restaurant s)

�Zone billing can be combined with m-advertising services

Conclusions

� ZigBee application profiles represent a new emerging techn ology for enabling theInternet of Things� Energy and Home applications use ZigBee as consolidated technology in the market place� Commercial Building automation will be probably the next profile to be released� New emerging profiles enable Location Based Services, health care using ZigBee

� ZigBee defines the “building blocks” for designing a wide ra nge of services� Cluster libraries have been designed to be general and reusable by different application areas� ZigBee PRO feature set has been used for different applications and offer a robust stack for industrial,

home and telecom applications

13


� ZigBee PRO stack is a consolidated stack for harsh environments (tested in many deployments)

� ZigBee success is linked to the need of a standard for both sta ck and applicationmessages:� Started from application requirements driven by expert of the specific fields� The standard maximize the reuse of existing features (application and protocol)� Volunteer based organization � interested companies are involved in the specification activities and

participate to the Alliance
