Hi CB,

> Is there a summary of why mobile networks are special and require treatment that is above and beyond dsl / cable / enterprise networks?
You’re right, this needs to be more explicit. All are regulated networks (mobile/DSL/cable by licencing authority(s), enterprise by company), so for me the key distinction for mobile is radio signal volatility and rapid ingress/egress to the network. The resulting increased packet loss and cell congestion bursts arguably make queue management more important in radio: i.e. queuing the content by type so that it can be delivered according to latency/bandwidth requirements. The content type is harder (or not possible) to infer when encrypted. Would be good to know to what extent this is also a problem in  DSL/cable.

> I understand spectrum is precious, but so is copper and fiber plants.
Agreed, I don’t think that is a valid reason to distinguish mobile.

> I read the gsma document, but i found it to be unhelpful
This document was the basis for [1]: happy to take comments/issues at [2].
