3. Home network(1/2) Devices Application Requirements
May 2004
Home network(1/2)
Devices
WLAN AP, Desktop PC, Laptop PC, TV, Settop box ,DVD/VCR player..
Application
HDTV, VoIP, Web browsing, ..
Requirements
High throughput
Radio aware mesh routing

Home network(2/2)
ESS mesh functionality will be implemented into CE devices, not limited to Access Point Device
Consumer devices may have a single WLAN interface
One WLAN interface may handle both of “AP-STA link” and “AP-AP link” simultaneously.
ESS mesh should support low mobility (walking speed)
Satisfactory Connection throughout the entire home environment.
Easy user interface (not as a part of infrastructure but end-user device)

6. Enterprise network(2/2)
May 2004
Enterprise network(2/2)
There will be multiple ESS mesh domain in the network. Each ESS mesh domains are connected by IEEE802.3 Wired LAN.
Conformance with IEEE802.3 newtork
VLAN support
Multiple entrances to Wired LAN
Wired LAN（802.3)
ESS mesh #1
First floor
ESS mesh #2
Second floor
