A story of telecoms journalists chasing satellites in moist Snowdonia
In Disney’s 1940 movie Pinocchio, prime hat-wearing conscience-incarnate Jiminy Cricket famously sang: “Whenever you want upon a star, makes no distinction who you might be”. As we found on a current Virgin Media O2 (VMO2) journey to Wales, nevertheless, once you want upon a Starlink satellite tv for pc, it appears it does matter the place you might be – not less than somewhat.
VMO2 launched its industrial O2 Satellite tv for pc providing February, providing prospects the prospect to entry direct-to-device (D2D) satellite tv for pc connectivity for £3 per thirty days by way of a partnership with SpaceX’s Starlink.
Roughly eight months later, VMO2’s Director of Cellular Entry Engineering, Rob Joyce, led a gaggle of journalists on a moist trek into the hills of Snowdonia to check the service for ourselves.
Rain stops play?
Our first mission – which proved trickier than anticipated – was discovering a ‘not-spot’.
Unsurprisingly, given its geography, Snowdonia is suffering from not-spots, starting from small sections of distant street to giant swaths of the mountains (take a look at O2’s protection checker for a better look).
Nevertheless, for our outing to the gorgeous Aber Falls (pictured), terrestrial protection remained strong for longer than anticipated. Solely after just a few kilometres off the crushed monitor have been we lastly seemingly out of vary of O2’s cellular community.
At this level the O2 handsets supplied for us ought to have robotically switched to the satellite tv for pc community, however no. As we stood within the rain below a closely overcast sky, we puzzled whether or not the climate was impacting the service.
Water absorbs microwave radiation at completely different ranges at numerous frequencies; a microwave oven, for instance, sometimes operates at a frequency of round 2.45 GHz, a frequency chosen particularly to dump most of its power into the water molecules inside meals.
O2 Satellite tv for pc makes use of spectrum within the 1,800 MHz band. In heavy rain, may this trigger sufficient disruption to cease us connecting?
“Rain ought to trigger little or no attenuation at 1,800 MHz,” defined Joyce, noting that this band is already extensively used for terrestrial 4G LTE providers. If rain have been to intrude with spectrum at this frequency, terrestrial providers would have felt it much more intensely than satellite tv for pc connections.
“In spite of everything, a sign coming from a cellular tower a kilometre away would go by way of far more water than the satellite tv for pc sign coming down from above,” added Joyce.
The most probably rationalization for the connection failure, Joyce defined, was that the units have been nonetheless making an attempt to connect with the terrestrial community that they had so lately had entry to.
A short time later, at a well known not-spot at Pen-y-Go – the start line for numerous climbs up Yr Wyddfa (Snowdon) – our telephones started to show the SAT image indicating satellite tv for pc connection.

The service itself was intermittent however efficient. Utilizing the Satellite tv for pc Tracker app from Star Stroll, we watched Starlink satellites hurtle throughout the sky above us at 17,000 mph, our connection blinking out and in at common intervals. This was greater than sufficient to ship texts, use numerous apps, and conduct Web-based voice calls.
For now, Starlink’s service is proscribed to simply fundamental information providers, with every satellite tv for pc able to delivering round 50 spot beams, every protecting a diameter of roughly 50km and delivering roughly 4Mbps throughout its person base.
Nonetheless, in an space the place there would beforehand have been no connection in any respect, that is transformative for customers. Whereas O2 Satellite tv for pc subscribers is not going to be downloading Netflix exhibits or cloud gaming over the service any time quickly, they are going to definitely be capable to message family members from among the UK’s most distant areas.
“Clearly, it’s not meant but for doing high-bandwidth purposes. It’s there for reassurance of protection past the present mobile footprint,” mentioned Joyce, noting that satellite tv for pc has elevated O2’s general community protection from 89% of the UK to 95%. “That’s why we’re not promoting it as a substitute mobile service. It’s bought as a service that reassures you that you’ve protection once you want it for these moments that matter.”
Huge plans for the long run
Joyce’s ‘but’ is vital right here.
Starlink’s D2D service is presently reliant on round 650 satellites, however this is not going to be the case for lengthy. SpaceX is predicted to start launching its V2 satellites subsequent yr, with roughly 20x the throughput functionality of their V1 predecessors. The Starlink web site guarantees ‘full 5G mobile connectivity with a comparable expertise to present terrestrial service’.
“In model two of the satellites […] we’re going to have much more bandwidth. I feel the determine is 20-times or 100-times the capability, relying on how a lot spectrum you deploy,” defined Joyce. “Service may then be similar to terrestrial.”
SpaceX has additionally lately purchased 14MHz of 800MHz spectrum within the US. If the brand new Starlink satellites can use this spectrum, then O2 will doubtless be capable to make use of the 10MHz of spectrum it owns in the identical band, too.
Taken collectively, this might imply that O2 quickly has much more dependable protection and an enormous enhance in capability.
Regardless of this, Joyce stays extremely sceptical that satellite tv for pc may ever actually exchange cellular providers.
“You’re not going to have the protection deep indoors […] and also you’re not going to have the capability to ship a service to the quantity of visitors that’s now provided to a mobile community,” mentioned Joyce. “The legal guidelines of physics say that due to the spectrum and due to the propagation, the satellite tv for pc can’t exchange mobile […] I feel it would at all times be a complementary expertise.”
For now, O2’s fledgling satellite tv for pc providers stay restricted in scope, if not in protection. However maybe it is not going to be lengthy earlier than they’ll serenade their prospects with the promise that once you want upon a Starlink your goals will come true.
