Noticed last month that Openreach had applied the 3db download margin onto my local cabinet (was previously 6db, they're able to do this for Huawei cabinets, not the ECI ones yet) that my modem is syncing the full 40/10 FTTC package I have with EE home BB. Fired in tests with a few different sites to see what they came up with...
The download speeds are reasonably consistent (except the last one) though the uploads vary a bit, especially from the Think Broadband test.
As for LTE, I'm on EE PAYG. On the ground floor of the house reception is poor to non-existent (2G, 3G or 4G) so I've an EE Signal Box to provide coverage around the house. Upstairs is better however, though two different BTS masts give better reception in different rooms.
So at the back upstairs room...
...while at the front upstairs room (notice the weaker signal strength)...
...I reckon in both cases the download speeds could be faster, I think they have a speed cap of 30Mb/s for PAYG users nowadays (Pay monthly users either get a speed cap of 60Mb/s or uncapped for the more expensive packages) - I remember a couple of years ago when EE were giving away free SIMs with two months of 100GB of data a month that I was able to push over 50Mb/s with them. I only seem to be able to get "single speed" with EE for LTE as opposed to "double speed" or "carrier aggregation" the latter of whom gives the fastest potential speeds with the most capable mobile phone in an area with the most spectrum available (EE tout up to 1Gb/s download but that's of course theoretical).
You can get mobile broadband "as home broadband" from EE but the prices aren't cheap, going up to £100 per month for a 200GB data cap for £18 months (100GB is £75, 50GB is £50, all come with free router). 3 OTOH have a 40GB data "homefi" package that is £23-24 a month or down to £21 a month for sim-only if you're willing to stick to a 24 month contract, they reportedly have a 100GB package per month for around £30 but it's not available online, only in-store. Apparently it's only in certain stores because in those which don't have the offer available are in parts of the country where their network is the most congested.
