Vodafone first space-based video call from rural Wales

A remote part of mid-Wales has become the backdrop for a major technological milestone, as Vodafone successfully made the world’s first space-based video call using a standard mobile phone and satellites designed to deliver full mobile broadband coverage.

I wonder if that is classed as roaming?

Cheers!

Isn't this just standard mobile but instead of backhauling the connection via a physical line they are doing it via satellite? I would suggest many people with Starlink have made video calls on a standard mobile phone.

I think you would need a Starlink base station to do that, this only requires a mobile phone.

Depends if the satellite is transmitting a Vodafone code and acting as a remote base station on the UK network, or if the satellite is a different LTE network host that is partnering with VF.

Someone needs a Starlink base station to do it the Vodafone way - the only real difference is that Vodafone are providing Starlink as the backhaul. It is just another form of backhaul - it isn't exactly groundbreaking to change one part of the backhaul to satellite.

It is good that it allows them to expand mobile networks without having to put in infrastructure for a wired backhaul but it is essentially no different to someone putting Starlink in at home and could even use a 4G base station to provide 4G to phones - people have been able to do this ever since Starlink became available (technically it could have been done before Starlink but it would have been expensive and the old satellite networks were higher orbit and had higher latency).

I am not belittling the fact Vodafone have done it to connect a remote community but this isn't some amazing technical feat - it is a very basic feat of engineering from what I can see of the solution.

There are actually two stories that I have seen..

I believe the Welsh satellite one requires a mobile phone with satellite capability which isn't that common.

There is also a story about O2 (?) using a Starlink connection as the backhaul for a new phone mast at Craster - previously a mobile not spot. Less high tech really but probably more useful to most people.

I may have mixed up the 2 stories as I have seen both today.

So, it appears Vodafone have actually got their own satellites in orbit that are delivering a 4G/5G signal to the ground - but they also state "space-to-land gateway" which to me sounds like a ground station that bridges the satellite and mobile capabilities - the phones certainly don't have satellite capabilities if they are standard handsets so either they are delivering mobile direct from orbit or they are using a gateway and if they are using a gateway then I believe the solution is as I thought it was.

EDIT: OK, so the register article suggests the space-to-land gateway is to connect the satellite to the mobile network rather than to the end device. I hadn't seen the NTN standard before so this seems to explain it in which case I cancel my previous statement and it does appear it is a direct connection from handset to satellite - so, interesting solution and will others follow the same path or are Vodafone a lone wolf due to the costs involved.

Although "standard" smartphones will work with the satellite service, these must be models compliant with the non-terrestrial network (NTN) capabilities specified in Release 17 and 18 of the 3GPP standards, which older phones might not be, but all devices going forwards will.

As per the article the Starlink connection is supplying a temporary 4G service until the connection to fibre backhaul after which 5G will be available. The printed story in the newspaper adds that Vodafone will bring their services to the mast once the fibre is connected but that EE have no plans as yet.

Because of the topography there was only an area of roughly one mile square without signal but that area probably sees about a quarter of a million visitors each year. We still have a BT phone box because of the necessity for visitors to be able to contact the emergency services if required (although that box will obviously only have a limited life now).

Walking the dog I can see that the civils have been done and the ducting is currently lying in a trench waiting for the fibre to arrive.

It is not quite true though.

For years it has been possible, whilst on an aircraft or ship, to use a standard mobile phone to make a call through an on-board pico cell which is then routed via satellite.

Mobile connectivity has been backhauled across satellite links for 25 years.
