o2 LTE frequencies

[Anonymous]

I'm in the Northwest of England. Following some googling I've come to the conclusion LTE / 4G is served by O2 round here, on the following frequencies:

852MHz - 862MHz uplink, 811MHz - 821MHz downlink in the 800mhz FDD band 20

.. or maybe

around 1713MHz & 1808MHz in the 1800MHz paired band

Am I correct, are these the correct figures to base buying decisions and antenna design considerations on?

If it works I'll send you a Blue Peter Badge....:smileywink:

Higher frequencies can carry more traffic and will penetrate buildings better so all swings and roundabouts.

I Thought the lower the frequency the better the bulding penetration and lower capacity  higher frequencies had greater capacity and poor building penetration?

Yeah, one way or t'other - it's all a trade off either way

@Anonymous Remember that you need the antennas to be wide band as the divice will be using mimo  so each will be recieving and transmitting so a wide band design will be better and most also use cross polarisation between the 2 antennas for full mimo effect.

I wasn't sure if O2 actually did use cross-polarisation / MIMO? A question I'll have to look into..


I'm now wondering whether I'd be better with a pair of 6-element collinears cut as best as possible for the centre of the LTE frequencies of interest.. say 835MHz

Would they be likely to be more wideband?


Not as directional as Yagis, but still with some gain and the possible added benefit of being slightly better for getting the 3G towers at all points of the compass? (although the 3G frequencies would be totally wrong for the antennas I guess)

[adamtemp64]

If tuned to Center frequency it may not have a wide enough bandwidth and good Vswr to prevent damage to the transmitter. (Worth checking the impedance required as well)

I can say I have used an external mimo antenna purchased from eBay (also covered 3G frequencies) on the o2 e8278 dongle and the performance was really good form 5 mb to 25mb download speed

ooh.. have you got more details?

There are so many on ebay, it's hard to know which are any good and which just have a pair of SMA connectors, connected to nothing, with sheets of toilet paper inside the antenna lol

It would be good to be able to purchase something that someone else has actually had some form of positive experience with!

Mine requires ts9 connectors so cannot give exact details  but was one of many advertised made by eternal comms find one that matches your dongle
