RE: stds-802-mobility: Hand-off question
There are so many wireless technologies, operation at different
fequencies (900, 1800, 1900, 850, 2400, 3500 MHz) and standards
available. I do not think these standards were designed to take care of
inter-technology handoff. As market need changed, some of the standards
made provision to support inter-technology handoff.
We need to analyze even for existing standard that what is currently
supported in 2G as well as 3G and what is roadmap for these standards.
Also, this needs to be worked very closely with otehr standards bodies
(3GPP, 3GPP2, etc.)
Again if I understand correctly, 802.xx is mainly about developing PHY
and MAC and rest is addressed differently. In the similar argument,
802.11e will suport QoS etc. But suppport of voice (codecs), VoIP (all
signalling) and all new streaming media video application is out of
scope over there.
just my 2c,
Thanks
