TR-41 VoIP via WLAN Projects

• PN-3-0102, Requirements for a Wireless LAN Based IP Telephony Subsystem– Will address requirements for enabling VoIP

telephony communications via WLAN in a corporate environment.

– Will not address residential and Public Access WLAN environments.

– Will reference and draw heavily upon IEEE 802 layer 1 and 2 requirements while also addressing level 3 and higher requirements.

TR-41 VoIP via WLAN Projects

• PN-3-0103, Requirements for a Wireless LAN Based IP Telephony Endpoint– Will be patterned after TIA/IS-811 but will

cover products with a WLAN interface instead of an Ethernet Interface.

– In addition to WLAN support, it will address requirements for dial, keypad, and telephone feature operation, acoustic performance, EMC, power consumption, control protocol, security, etc.
