HITS, I take it you didn’t view the webinar. Very strange how you seem not to be able to process simple data and even stranger that you seem to deny the EE project exists. Here are some quotes from EE:
“EE’s contract will see it build more than four hundred new 4G sites and develop a “resilient” core system to support the ESN across the UK. The network will be able to prioritise ESN traffic when required, and EE with partner Avanti will introduce satellite cellular backhaul to over nine hundred fixed base stations and portable base stations across the UK for hard to reach areas, as well as fixed backhaul elsewhere.” So HITS it seems unlikely that EE have invested so far $30m USD in a temporary not fit for purpose as you suggest.
“Mansoor Hanif, director of radio access networks at EE, said Avanti "will play a key part in providing the resilience" and increased coverage the operator is seeking to provide through its 4G network.”
Going by our past conversations even though the evidence is right in front of you I still think you will question it. You seem focused on the latency issue, with the commercial kit being used you will find that 500-600ms access to the core, let’s say 500ms, that’s half a second! I really don’t think your average Joe will even notice half a second and given the fact this is acceptable for the UK home office for our entire Emergency services this confirms you are incorrect again. With advances in technology to assist the traffic I have listed some of the functions below, if you choose to educate yourself then great, if not that’s fine but it does seem like an episode of the vicar of Dibley, you say NO NO NO NO NO whilst the satellite operators and MNO’s say YES.
With regards to speeds, They are not using residential kit capable of 30 down 5 up they are using kit capable of 150mbps and 50mbps up (probably more) with their own hubs installed at the gateways and prioritised traffic and they will be in full control of bandwidth allocation.
And with ref to your distance point, it’s not 80,000km one way as you describe its 36,000 each way so equals 72,000km return hop.
TCP acceleration
Forward Error correction and modulation
Serialization delay
There is some very interesting information on sat backhaul and future 5g information listed on the European space industries website here which may explain it better than I can.
