Hi Mark,
Thanks for your efforts. Your suggested usage model of applying the analog repeaters to connect the MMR-BS and RS in the village is worth to be used as an implementation case.
But, I think the usage of analog repeater in MMR network may be out of the scope in MMR usage model document.
Besides, the repeater is usually used to extend the converage area or compensate signal hole of an MMR-BS, so from the aspect of MAC layer, the repeaters belong to MMR-BS. The village case you mentioned could be included in the "Fixed Infrastructure Usage Model".
Best Regards,

主旨： Re: [STDS-802-16] [MMR-AH-UM] Announcing 6/22/06 Meeting of Multihop Relay Usage Model Ad Hoc Group
I have looked at the new usage models and I think there may be one scenario missing. It arises as follows: There may be an area outside a BS coverage area (e.g., a small village outside a town) where it is uneconomical to deploy a BS because of the low amount of traffic in this area. Conventionally, this problem is solved with an analogue repeater, designed to extend the BS range or bypass an obstruction (e.g., a hill) in order to provide coverage for this village. We may then expect similar coverage in the village to that in the town. To improve this level of coverage in the town (e.g., for higher rate services) we may deploy multihop relays. So we would similarly expect to deploy multihop relays in the village in order to provide similar services. But in this case the multihop relays would connect via the analogue repeater to the base station, rather than directly to the base station. Although we could replace the analogue repeater with a multihop relay to avoid this scenario, it may not always be the best option and so for the moment I would like to suggest that it should be included in the usage models.

Mark

Dear Ad Hoc participants,
The next meeting of the Multihop Relay Usage Model Ad Hoc Group will occur on Thursday June 22, 06:00 – 07:45 PDT (13:00 – 15:00 UTC). (Note that we will finish 15 minutes earlier due to conflicts).
The bridge for the meeting is 916-356-2663, Bridge: 2, Passcode: 3578218
I have updated the draft to include modifications to the outline that we agreed to in the June 15 meeting. It can be found in the following location: http://dot16.org/CSUpload//upload/temp_db/C80216j%2d06_UMAHtemp_r4.doc
Please review the changes to make sure they are consistent with what we decided.
The main topics planned for the meeting are:
- Go over any issues identified in the current version of the document
- Discuss the new usage model proposal put forth by Matt Sherman (Matt will upload updated version prior to the meeting
Please send comments and issues that we need to discuss to the mail list prior to Wednesday June 14 8 AM PDT. I will send out a detailed agenda for the meeting on Wendesday.
Regards,
Jerry Sydir
