2. Service Coverage Extension
Purpose
STAtions (STAs) experience high path loss in 60 GHz band, and hence, the short transmission range might be a major drawback.
We recognize that new strategies are required of consideration since the existing technologies are not suitable for the 60 GHz band wireless environment, where directional transmission and reception technologies are necessary.
More Considerations for Service Coverage Extension
It is required to modify the existing technologies, including mesh network, WDS, and ad hoc network.
Exclusive relays are useful to extend the service coverage.
Stations’ cooperation contributes to the service coverage extension.

3. Suggested Text for Functional Requirement Document Draft
TGad stations extend their service coverage by the help of either neighbour stations or dedicated relays when the stations either experience poor link quality (i.e., unreachable transmission ranges) or require higher data rates. TGad stations accomplish the service coverage extension with the three scenarios; (1) neighbor stations pass along data frames by building a multi-hop wireless ad hoc network; (2) an elected neighbour device cooperates with source device in order to improve transmission throughput and to make a seamless communication; (3) a relay is utilized to transfer data and management frames to a destination device when there exist unavoidable obstacles including walls, closed or isolated rooms, and other practical entities between the source and the destination devices.
[Req01] The TGad devices build and exploit multi-hop wireless network for service coverage extension.
[Req02] The TGad devices have the ability to participate in transmitting together with a source device in order to improve transmission throughput.
[Req03] A relay is used to increase transmission coverage.
