2. Peer Aware Communications (PAC) Scope, Purpose, and Needs

3. Distinctive features for PAC SG
Peer Aware Communications (PAC)
Key features: Fully Distributed coordination, Infrastructureless and Peer-to-peer Communications
Discovery for peer information without association (peer=device and/or services)
Fast association
Discovery signaling rate -typically 100kbps
The number of devices in the discovery >100
Each device may support several applications
Data Transmission rate -typically 10 Mbps
Group communications: n to m
multi-hop relay
Relative Positioning -typically 10m
Security, Privacy, Trust
Globally available Unlicensed/licensed bands (e.g., below 3GHz, 60 Ghz, UWB)

4. Scope
This standard defines the PHY and MAC specifications for Peer Aware Communications optimized for peer to peer and infrastructureless communications with fully distributed coordination.

5. Purpose
The standard provides peer to peer and infrastructureless communications with fully distributed coordination. It features: discovery for peer information without association, fast association, typical discovery signaling rate of greater than 100 kbps, the number of devices in the discovery of more than 100 devices, scalable data transmission rates of, e.g., typically 10 Mbps, n-to-m group communications, relative positioning, multihop relay, security, and globally available bands.

6. Need
In order to support burgeoning social networking and peer-to-peer applications for mobile devices, the awareness of their proximities for desired services is an important feature for future wireless communications. Current communication infrastructure can support those applications but incurs unbearable signaling overhead and communication latency when to support hundreds of devices in the proximity. Additionally, applications such as social networking requiring security, privacy, and trust will be supported.
Potential applications include social networking, advertising, gaming, streaming, urgent notification, device control, p2p services, internet of things, and etc.
The fully distributed network without infrastructure is not only useful for crowded places such as mall, stadium, campus, amusement park etc. but also isolated places not supported by infrastructure. It is also useful for emergency situations such as flooding, earthquake, fire, and etc.
