Subject: [Ecrit] airport 802.11 example

Just wanted to mention that the example that James gave with location determination in a multiple 802.11 AP environments is solved by using LLDP-MED.  In roaming situations, at registration of a mobile IP phone with a new AP the LLDP-MED location TLV will transfer the new location info from the AP to the IP phone. The reason the 802.11 folks may have not mentioned the solution is that LLDP-MED is higher than the MAC layer (their scope) but yet below the IP layer. 

Still, the requirements document has an important role in translating the regulatory requirements for accuracy and timing into component requirements for ecrit.  

Regards,

Dan
