Re: [gaia] Fixes to "Alternative Network Deployments" Internet Draft

[Arjuna Sathiaseelan <[e-mail]>]

Hello Steve,
  I think this is a good suggestion and we should also add 802.22.

Also I think we need to add more details on TVWS. We will work with
Marco and Ermanno on this.

Thanks once again Steve.

Regards
