thanks for this info, I am on band 3 and also good signal indoors, so band 3 can penetrate also I guess if conditions are right.
Band 3 (1800mhz) is the same frequency that Orange and T-Mobile(formerly one2one) ran their 2G signals on for nearly 20 years. So yes, its the main frequency for EE and its gets indoors in most buildings without problem. Its quite close to 2100 which was used for 3G on all 4 networks for over a decade.
However the 800mhz is quite new, and often only in rural areas for EE. Three has a bit more, but Vodafone and O2 have usefully more and have made it their main 4G transmission.
This is why you'll often see 25mbps on O2 or Vodafone and 80mbps or faster on EE.
For reference the app you mentioned wont run on my S7, it says the base quallcomm driver is needed and missing, however the app 'LTE discovery' told me which band I am on.
No, samsung phones don't have Qualcomm CPU or radio hardware. The NSG app needs Qualcomm radio hardware and also needs the phone to be rooted to do anything useful. Cellmapper is pretty good on non-rooted phones of all types. A Moto E 2nd edition LTE (2015) can often be found on auction sites for peanuts and is easily rooted. (The 3rd edition is not Qualcomm).
There is no standardisation in Android, and so its hard to get the technical details. LTE discovery is okay, but sometimes tells untruth's. Samsung's engineering mode screen is more reliable. (good for how to get there, as its different per phone).
Keeping it broadband related, my Netgear AirCard 810 shows these details on its menu, it also has two antenna sockets on the back for external antenna.s
