本标准定义了无线个人区域网（WPAN）对等感知通信（PAC）的PHY和MAC机制，该通信针对具有完全分布式协调的对等和无基础设施通信进行了优化。PAC功能包括:无关联的对等信息发现、发现信令速率通常大于100 kbps、发现网络中的设备数量、可扩展的数据传输速率（通常高达10 Mbps）、多个组中同时具有成员身份的组通信（通常高达10 Mbps）、相对定位、多跳中继、安全性、，并可在11 GHz以下的选定全球可用未授权/授权频段运行，能够支持这些要求。

This standard defines PHY and MAC mechanism for Wireless Personal Area Networks (WPAN) Peer Aware Communications (PAC) optimized for peer to peer and infrastructureless communications with fully distributed coordination. PAC features include: discovery for peer information without association, discovery signaling rate typically greater than 100 kbps, discovery of the number of devices in the network, scalable data transmission rates, typically up to 10 Mbps, group communications with simultaneous membership in multiple groups, typically up to 10, relative positioning, multihop relay, security, and operational in selected globally available unlicensed/licensed bands below 11 GHz capable of supporting these requirements.
