Common Understanding (1 of 2)two PHY types

• a low rate PHY to service long range applications ( < 1 Mbps, > 10 m )• a high rate PHY to service short range applications (> 1 Mbps, < 10 m)

the two PHY types should coexist while not requiring interoperability. 

• PHY and MAC headers that minimize the overhead for low rate PHY applications• meeting the more demanding needs of the high rate PHY applications.

a common VLC frame structure

single MAC protocol design that can service both the High Rate and Low Rate PHY designs

Common Understanding (2 of 2)

VLC application modes : P2P, VLAN (without backhaul, including infrastructure illumination), IB/VB broadcasting and visibility support.

• Infrastructure continuous illumination and point-and-shoot support using visibility

frame formats (Beacon, Acknowledgement, Management, Data, Visibility) and related MAC commands.

frame flicker compensation via the use of compensating visibility idle patterns.

To accommodate light dimming , the ideal solution when possible, is to intercept the dimming command at the MAC frame format level and adjust the frames and visibility idle patterns accordingly
