RE: stds-802-mobility: Differences between 802.16 SG and EC-SG mobility PARs
Marianna-
I do not understand your distinction between a "mobile device" and "mobile
feeding". If I use the analogy of a cable network and extending your
definitions, a cable modem connects to the "fixed device". But the user can
have a router as the device, and a network connected to the router. For
this case, is the cable modem doing (as you define it) "fixed feeding"? And
what is the difference to the protocol on the cable system?

PARs
Hi,
I address this e-mail to both Mobility Study Groups, as we have
to clarify together the differences between our PARs, in order
to help EC to make a decision. Should be clear that the
purpose is not to show which PAR is more attractive, but to
better define the actual PAR targets.
I see the main differences between the 2 PARs as being:
1. The targeted radio bandwidth:
- EC SG: 1.25MHz, up to 5MHz
- 802.16 SG: 3-28MHz
2. Targeted applications
- EC SG: user mobile device
- 802.16 SG: user mobile device and mobile feeding.
802.16 has mobile feeding capabilities due to the larger radio BW.
3. max. 250km/h issue:
- EC SG: user mobile device
- 802.16: train mobile feeding; inside the train can be anything,
including WLANs.
I propose to work together, in order to have, before the November
meeting, a clear idea of how can we improve the PAR texts.
This e-mail just start the process. Please comment.
Regards,
Marianna
