That's what I mean I think lol. So L2100 and L1800 at 5mhz would have a max of 37.5mb does the higher frequency only allow more users on the site. Please don't hand your heads off the wall. I'm a virgin when it comes to frequencies.
Edit I understand high and low from a signal point of view.
The frequency is irrelevant to cell capacity. It's the bandwidth which determines the maximum speed available and the number of users allowed on the cell. For 5Mhz bandwidth it's a theoretical maximum of 37.5Mbps, and that will be the same whether it's on 800, 1800 or 2100 (or whatever other frequency).
Only difference frequency makes is that a lower frequency will propagate better (i.e. 'go further' and penetrate building materials better).

Thanks so my understanding of high and low frequencies was right. Thanks for clearing up the bandwidth for me.
Am I imaging it or is there a pattern here - All the places i've seen O2 roll out L1800 are in the East (O2 area) and the places reported to have Vodafone L2100 are in the west (Vodafone area). Each operator has a bit more "play" with their own kit as well as giving access to the partner network. Perhaps the partner agreement doesn't yet cover 4G other than L800 or it's just taking longer to get sorted - Or I could be taking complete rubbish!!

On the nperf map on O2 it's only the east that has "4G+". Vod only London and west for 4G+. So yeah there seems to be a pattern.
Cellmapper shows O2 1800MHz on the M6 Coventry, Wood Green (London)
Vodafone, 2600MHz, Cell/CI 28 @ wembley stadium, However there are Unknown Bands for Cell/CI 143, 246 what is more then likely 2100MHz?
Vodafone Unknown Bands found on CellMapper?
143, 246 was picked up near Briggate, Leeds, LS1 6LL
Clapham Junction, Cell/CI 193, 195
Brockley Cross, London SE4 2LY Cell/CI 167, 170
Bank Station (Tube Station) London Cell/CI 52,57,58,59,88,92,93 (largest phone mast sector) and another site with Cell/CI 4,65
London SW1V 3JL Cell/CI 14, 34
Bishopsgate, London EC2N 3AQ Cell/CI 15,16,174 with a maximum signal (RSRP) -53 dBm for cell 15, -65 for cell 16, -81 for cell 174
About 2/3 of the masts I've visited in Manchester City centre are L21 enabled. I'll get around to posting a map, but feel free to PM if you want a list. Again speeds of 10-20Mbps, apart from one monopole which gave a peak of 30Mbps.
I've noticed that 2600MHz masts don't appear to be receiving L21 as of yet.
Woopie:)
Now, someone release a phone/tablet/dongle/mifi which has 4 antennas and reasonable power consumption. In the meantime we'll be grateful for the improved cell edge performance and uplink speeds
It'd also be nice if Vodafone would also consider trials outside of Newbury and London mind.
If Vodafone used the 1800,some of 2100 ans 2600 for 4G on every mast then they can use the 4G800 on full power. So priority 4G2600, 4G2100, 4G1800, 4G800 This is just my opinion. Sorry if I am wrong

I agree - what I would be thinking is as follows:
900: 2G/3G with a DC-HSDPA carrier (so 10MHz, not the 5MHz they are using currently)
1800: 4G
2100: 3G/4G (in time becoming 4G only, using the 900 for 3G)
2600: 4G
This clears out 800 for full power VoLTE use.
O2 would be much more difficult as they don't have any 2600; they just have 800, 900, 1800 and 2100. And I doubt that 5MHz of 1800 would work as their main layer. They'd have to roll out a nationwide 2100MHz 4G, and use their 900 for 2G and 3G.
Though No.1 priority is to actually get modern day technology to most places. Thrapston, Northamptonshire isn't that small - and it has EE/3 3G2100.
O2 2G900/1800
No Vodafone mast for Thrapston, but there is some 2G900
C'mon Vod/O2, catch up and get that O2 mast CTIL'ed for 2G900, 3G900, 3G2100, 4G800 and 4G1800! (Though, even 900/900/800 would be better than just 2G GPRS/EDGE on 900 and 1800.)

Most O2 owners until recently probably never knew what 3G was, so O2 can surely make it all 4G with few complaints!
That might be troublesome, from memory Voda only have 5 + 4.6 + 7.5MHz of 900 and it's in 3 non concurrent chunks.
Also, could they afford to only allocate 7MHz to 2G at this stage? A lot of users are still kicked onto 2G fairly regularly.
Didn't know about the non concurrent chunks, which I assume makes it more difficult/impossible to get DC-HSPA on 3G?
If every mast that was getting upgraded, went 3G as well as 2G, then of course they could afford it. What would be used for 2G, would be used for 2G and 3G, and the vast majority of handsets today have some sort of 3G compatibility. Plus, 3G could be used for calls as well as 2G, whilst increasing the data flow for customers.

And when they get VoLTE working nicely, they can reduce 2G to just 5MHz, before finally (in the long term future) making an all 4G (and 5G, when it arrives) network.
They've got to sort out the large %age of customers who still don't own a smartphone, though (doesn't O2 only have about 55% smartphone penetration?).

Question? Is it possible to run 3G and 4G on the same block of frequency or would that be too easy if it was possible and would solve all networks capacity problems?

Question to all? Is it possible to run 3G and 4G on the same frequency block? For example 2150-2160mhz on 3G and 2150-2160 on 4G, or if that was possible would it be too easy and I assume it would solve everyone's spectrum and capacity problems overnight??

I don't really know too much about exactly how the frequencies work, but I'm sure that you'd have to have separate frequency blocks for each technology. If the 2150-2160 was being fully utilized for 4G, you couldn't use the exact same frequency block for 3G.

At least that's how I think it works, anyway...
Your more than likely right it would seem to easy if that was the case. Take 3 for example, they have regularly said they need more spectrum and want to be favoured if you like in the next round of spectrum.

It took 16 years [after the 3G auctions] to get 3G to Raunds, and some places still don't have 3G (let alone 4G), so I wouldn't get my hopes up.
