USO - no geostationary satellite28 Mar 2018 13:23
The government today published the results of OfCom's consultation into the forthcoming Universal Service Obligation - including a minimum service specification - which will define future government strategy.
The USO will be a legal right for every premises to have access to a broadband service of minimum 10 Mbps download and 1 Mbps upload for free (up to a maximum cost of �3,400 for provisioning the premises - with industry expected to fully fund that cost). Any additional cost over and above that will need to be paid by the premises owner. No government funding is being made available.
As expected, geostationary satellite-delivered broadband has been specifically excluded as a feasible technology to deploy because of the maximum latency criteria (max 200ms). The speed of light (300,000 km per second) means that a round communication trip from say London to a geostationary satellite above the equator and back (40,000 km x 2) is going to take 266ms - and that's without any other lagging factors. (Typically in the real world, satellite broadband latency ranges between 600-900 ms).
Short term, the slightly better news is that the existing subsidised 2 Mbps Universal Service Commitment scheme is set to continue for at least another 9 months - and probably beyond that, because it's going to take a couple of years to decide how to implement the USO, now it's been defined both technically and commercially.
However, the UK at least is going to see an ever more rapidly -increasing marginalisation of satellite (and thus decreasing of number of properties provisioned) over the next few years. SSW's Quickline acquisition had better pretty rapidly step into the forthcoming breach.

Section 4 (page 23) of the document states:-
"Ofcom�s December 2016 technical advice to Government was that a wide range of current technologies could meet the proposed specification: fixed (notably Fibre To The Premise (FTTP)28, and Fibre To The Cabinet (FTTC)29, fixed wireless, and mobile technologies. The technologies that Ofcom looked at were selected because they were available and in use at that time; offered the opportunity to provide coverage across the UK; and the costs associated with them were relatively well understood.
We understand from Ofcom�s 2016 technical advice, that based on its current capabilities, particularly on latency, current satellite broadband services, which use satellites on a geostationary orbit could not meet our proposed specification."
