WLAN users today
• Primarily PC centric market– Limited data rates in the past– Limited/No QoS facilities– Lack of market readiness/perceived need for a
wireless technology

Submission
WLANs in the future (1)
• Increased consumer awareness of WLAN technology with the WiFi logo & branding
• Newer standards such as 11a & g support higher data rates, paving the way for entry into multi-media applications
• Soon to be released 11e standard expected to further increase the capabilities of WLANs

Submission
WLANs in the future (2)
• In the near future we expect WLANs to have two major target markets:– Traditional PC Market
• PC cards, routers, laptops with integrated WLAN
– Emerging CE Market• Home AV network – TV, VCR, AV server etc
• Public Access Networks – cellular phones and portable devices

CE Market Requirements (2)
• Application domains of WLANs:– Residential– Enterprise– Hotspot
• Today, no single CE application (Residential) requires data rates higher than 28.8Mbps (DV-camcorder)

Submission
HT Technology Requirements
• Adaptable to various environments (markets)– HT WLANs will need to achieve more efficient
medium access, irrespective of use-case
– Total throughput in the BSS must be 100Mbps (PAR)
• Scalable to different STA requirements– Different No. of STAs dependent on use-case
– Different device data rates dependent on use-case
– Power and Form-factor of mobile devices should be accounted for

Submission
Problems to be Addressed
• HT technology must cater for:– Portable handheld devices (cellphone form-
factor)– Large no. of simultaneous users– Aggregate network throughput and capacity
• HT technology must not:– limit itself to being a point to point cable
