doc.: IEEE n Submission September 2003 Rahul Malik et al/ PanasonicSlide 2 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

doc.: IEEE n Submission September 2003 Rahul Malik et al/ PanasonicSlide 3 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

doc.: IEEE n Submission September 2003 Rahul Malik et al/ PanasonicSlide 4 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

doc.: IEEE n Submission September 2003 Rahul Malik et al/ PanasonicSlide 6 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)

doc.: IEEE n Submission September 2003 Rahul Malik et al/ PanasonicSlide 7 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

doc.: IEEE n Submission September 2003 Rahul Malik et al/ PanasonicSlide 8 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 replacement
