Re: [802.19] Conference Call on TVWS Coexistence



Steve,

I agree with your point about not using the term "media independent". However, I would venture that wireless technologies utilize a number of different physical media. The physical layer is often called the "physical medium dependent" layer in the standards documents for this reason.

At the RF level you are correct, there is one medium through which the electromagnetic waves travel. However, the PHY layer of wireless protocols create from this single medium physical media that are dependent upon PHY layer characteristics.

Vivik,

My point is that for the wireless technologies there are not multiple Media, there is only one: Air. We are not dealing with multiple media. In 21 you also dealt with Cable so you had multiple media.

Steve and All,

802.21 WG is named as Media Independent Handovers (MIH) and yes media independent is a very widely used term in this group. However that does not mean that other groups cannot use this term, if it makes sense.

Co-existence does span across different media types and that's why this term probably keeps coming up a lot. Media Access Independent is fine too in that sense.

Best Regards
-Vivek

Sanislav et. al.,

Sorry I was unable to make the conference call this morning. I heard that there was some good discussion.

I was looking over your comments and you use the phrase "media access independent." I wanted to comment a bit on that phrase.

The term "media independent" has been used a lot in 802.21. To me "media" means either the Air for wireless systems or a cable for wired systems. So I don't think "media independent" is the best phrase for our purposes. You modified it to "media access independent" which to me means "MAC independent." I think that is much better. However, I think there may still be better terms. Some possibilities are,

1.	Wireless Technology Independent
2.	Wireless Standard Independent

There may be others. I tend to use #1. In that context a wireless technology is associated with a specific standard (e.g. 802.11, 802.16, 802.22, WCDMA, etc.)

	I am glad to see you and others providing comments.

Thanks,
Steve

Dear Steve,

We have reviewed the draft PAR suggested to the group and we would like to make a presentation regarding our comments to the draft PAR during the teleconference.

Unfortunately at the moment we cannot upload our comments to the Mentor system, so we have attached the comments and a PAR suggestion resolving these comments to this email.

Could you please consider allocating us a time slot for the presentation?

Thank you.

Best regards, Stanislav Filin and Tuncer Baykas @ NICT, Japan.
