21、cification which specifies an interface for enabling remote user interaction of a mobile device via another device. The present document is written having a vehicle head-unit to interact with the mobile device in mind, but it will similarly apply for other devices, which provide a color display, aud

22、io input/output and user input mechanisms. IEEE allows defining vendor-specific Information elements, which are used to carry information not defined in the IEEE standard within a single defined format. The IE (Information Element) is located at the end of management frames, such as the beacon frame

23、 defined in 802.11 specification of IEEE 1. Multiple IEs can be concatenated. Based on the usage of IE, IEEE defines the formats of different kinds of IEs identified by the Element ID. The present document specifies the IEEE 802.11 CCC vendor-specific Information Element. 2 References 2.1 Normative
