As a non engineer, this is the first I have ever of this as an issue and I have never heard it from customers, very large or very small. Is this a real issue (I have already passed the comments to our PLMs for the product line) for operators? I do know that with firmware version 4.0 these radios support QinQ VLAN, which I've not heard other UL radios supporting. And one VL sector with 4.0 will support 288 concurrent VoIP calls (VoIP only play, 20MHz channel). That compares to 8-10 per Canopy sector and maybe 20 on a Trango sector.

For example, IPSEC. Microtik allowed us to get over the 1512 limit, as long as we were using WDS. Trango of course allowed the 1600, one of the reasons that we chose it 5 years ago. Any plans that Alvarion will make mods to allow larger packets? I'd support Matt's comment, that limited to a 1512 MTU could severally limit its viable use for service providers, allthough Corporate clients likely could care less, as they'd just design around it, since it was for their own network.
