Is Britain really worse at 4G than Peru?

300mbps 4G in the UK

300mbps 4G is readily available on EE in the UK if you can find a quiet mast in an urban location: https://twitter.com/PedroClarke1/status/853930150299398144 The maximum theoretical speed for that service is over 400mbps but the site being center of a city means it's rarely all that quiet. I regularly observe speeds of over 200mbps on Vodafone too. These are all obtained using 2x2 MIMO and 64QAM so with new devices able to better use what's deployed, the available speeds will improve even further, leading us to at least one network in the UK being able to do gigabit class 4G.

The Opensignal report does not break down the 4G results by operator which is sad considering one of the UK's networks really lets the side down

So is it 4.5G or LTE-Advanced Pro? Either way, it’s pretty damn quick

EE does CA on 1800MHz and 2600MHz, they only have 2X5MHZ on the 800MHz band.

They might, in future, use all three bands though.

White LED lies: It's great, but Nobel physics prize-winning great?

Re: Let there be light!

LED street lanterns tend to use more energy than the sodium ones they replaced. 35w sodium=35w+9w (ballast lossed)=44w. 60w LED +5w gear losses=65w. The main energy saving is the potential to dim them down yes, but unfortunately the GSM based control system is about the most unreliable system the human race has developed.

Re: LED Lighting: RGB vs UV/Blue + White/Yellow Phosphor

You are indeed correct. For an image, see here: http://www.lamptech.co.uk/Images/LED%20Lamps/LEDi%20230-12K58RP830-B22d%20Philips%20open%20lighted.jpg
