Full tx power and rx sensitivity data for MT radios?

Can we get complete information on the transmit power and receive sensitivity for recent radios? I'm particularly interested in the NetMetal5 SHP. Spec sheets on the web site look like they provide this information at first glance, but only a subset (and an obfuscated subset at that, I believe). e.g...

Re: MT alternatives for 17Km link?

Airfiber 5 need 8w 24v?????
AF5 need 42~58v up to 40w
According to spec AF5XHD runs on 24-50V @ 12W max (6W min, so 8W typ would make sense).

Much less than AF5 and more solar friendly. I have a 24V nominal power power system at the site.

Re: Wifi keeps mobile device awake? [keepalive packets]

Any news on this? I came on this thread after spending many days tracking down the reason for "push fail" on iOS devices using our WiFi network. Since I'm running 6.33.1 presumably I'm affected by the "fix wasn't implemented for virtual APs" issue.

Any Plans for IPv6 Policy Routing?

I just had to abandon IPv6 support in a project because policy routing is absent from the current release.
Are there any plans to add this missing feature? It appears to have been supported in the kernel for some time now : http://itkia.com/ipv6-policy-routing-linux-gotchas/

Thanks.

Re: How to label clients connected to an AP (non-WISP scenar

Think I figured it out : the clients are gone from the registration list because something about adding them to the access list causes dis-association. The client than takes a minute or two to come back and re-associate. Once it has done so, it is of course back in the registration list, with comment.
