VHT SG – Focus areas
VHT SG should look into features in the following focus areas:
Throughput : Maximum channel bandwidth ~ 80 MHz and Peak Data Rate atleast 2 Gbps
Range - Provide better/higher data rates at longer range than what is available with TGn
Power - Power consumption for traffic upload or download should not be more than half of what it would be when using TGn power save features and at the same range
Co-existence - WLAN system should be able to operate in 20, 40, 80 MHz mode and should be able to co-exist with legacy devices (802.11b, g, n) in the BSS

Specific targets for VHT SG - Throughput
Need for 2 Gbps : Primary usage for high bandwidth
Home : IPTV
Enterprise : Be up to speed with evolution of wired LAN
Hotspot : support multiple traffic streams of users
Improvement by a factor of ~ 4 over TGn

Specific targets for VHT SG - Range
Improved data rate at longer range :
WLAN is no longer just an indoor technology
Home : support for TX/RX of multimedia streams at all corners of the home
Hot spot & Enterprise : Deployments in large campuses
Target : Provide 100 Mbps at MAC SAP at a range of 100 m (expected to provide a factor of “X” improvement over TGn)

6. Specific targets for VHT SG – Co-existence

Specific targets for VHT SG – Co-existence
Should be able to operate in 2.4 and 5 GHz bands :
Flexible bandwidth operation : 20, 40, 80 Mhz
Co-exist with legacy deployments (11b, 11g, 11n)
If VHT ends up in 2.4 GHz band then it should provide mechanisms to co-exist with other technologies in that band (ex: Blue Tooth)

Slides for VHT SG - Device capabilities
Should support devices that can handle 1 to 6 Spatial Streams : This is already possible already with TGn
An AP should be able to support a minimum of 2 antennas and a maximum of 6 antennas
A STA can have any where from 1 (power save devices) to 6 antennas
