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

� 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
