Editing spectrum data for EE 4G Band 28, O2 5G Band 78 #48

Closed ExperiencersInternational closed 4 months ago

ExperiencersInternational commented 4 months ago

Country two-letter code

GB

JSON spectrum data file

spectrum-data.json

Hoping this should work fine, the spectrum editor isn't easy to use on mobile

What has changed?

Any additional comments?

O2 n78 650976: https://www.ispreview.co.uk/talk/threads/o2-speed-tests.41577/post-368014

EE B28 9460 (used very rarely by the sounds of it, one deployment is for coverage reasons pending installation of a new mast): https://www.ispreview.co.uk/talk/threads/ee-mvno-related-posts.40931/post-368875

Can't be bothered to update the JSON but I've also seen a 40MHz deployment in their lower block in outer London

Not in the area now since I don't live in the area so you'll have to take my word for it (about 2 hours away)

Just to confirm, someone has also just posted an example of the same NRARFCN, the exact point is around 3770MHz so it's clearly the upper 40MHz block (suspect spectrum swap has not occurred).

so it's clearly the upper 40MHz block (suspect spectrum swap has not occurred).

It's likely prep with radios that support post-swap spectrum but prior to the swap occurring in that area. Rare to see such smarts from Telefónica UK.

The 10MHz n78 is likely bad bandwidth data from the Band 1 LTE being applied onto the n78 carrier by Netmonster.

Yeah possibly, should have noticed it honestly. I do recall seeing someone else seeing a 10MHz deployment in the Lake District too.

O2 has been doing some odd stuff though, I have a 5MHz EARFCN 199 deployment near me that was recently added to the last B20-only site (I'm not sure if it's backhaul issues, Vodafone doesn't broadcast 5G n78 by the looks of it and relies on 5G ENDC from other sites) and I've had it show up on 2 sectors and it looks like other people have too on Cellmapper
