O2's Dire 3G Network?
I took this today http://oi62.tinypic.com/2dhh1z5.jpg This is not a one time thing, this is what I get every day on H+ O2 0.25mb Anyone else getting this?

It's caled having a network based on 900 frequency and only having 2100 as a 3G frequency for capacity, then hobbling 2g voice quality to squeeze in some token 3G.
Give it ten years and the 4g will be solid. |

I had the same thing on Vodafone where I was getting fairly decent 3G speeds in Harlow town centre until one day (around the time they started rolling out 4G) it dropped down to a download speed of .1meg and it did not change for the remaining 5+ months of my contract however many faults I logged with Vodafone (this was on my own phone and also my works phone so it was defiantly the network).
I left them just over a year ago (even though I was getting 20% discount through who I work for) for Three and could not be happier (decent 3G everywhere and can stream high quality internet radio from Poole to Harlow and also Basildon to Norwich with no issues (apart from dropping out for 30 secs on the Basildon to Norwich journey).. |

I constantly had even worse results than this on O2.
Switched to EE last August and never looked back. As of 2 weeks ago EE launched 4G here as well. Checked with my next door neighbour who still sticks with O2 (contract I suppose) and situation hasn't changed for him. |

How can that even be called 3G, EDGE would be better

I used to regularly register 0.01Mbit down, 0.00Mbit up and a ping of over 800ms with 5 bars 3G.... I was let out of my contract...

3G over 900MHz is typically MUCH slower than on the 2100 band

I find this really weird.
They have to be using 5Mhz (minimum on 3G) and 900 is only slightly less than half that of 2100 so why so slow??? Even if a 2100 cell was doing only 2 Mbps then surely a 900 cell should be able to manage nearly 1 Mbps??? Must be back-haul surely? EDIT: Have we tested the 3G900 on a 4G enabled cell anyone? |

so 0.05Mbps down, 0.02Mbps up, 1000ms+ latency. I think they've found a really bad dialup line and are using that for backhaul. Someone pointed out that perhaps it was done to keep Vodafone within any coverage obligations but without dramatically increasing rollout cost (presumably they can use the 900MHz antennas they have for GSM). Who cares what the performance is like as long as the 3G indicator shows up on the phone. Even the nearby O2 site can do 10Mbps+ (might be a 2100Mhz one) and of course EE/3 win with 20+Mbps and 4G imminent |

Maybe I'm lucky but I've only once did a speed test on O2's 3G network where the download speed was less than 1 Mbps - and that was 0.9 Mbps. O2's 3G network I generally find it to be consistently decent - not amazingly fast but good enough for general smartphone use on a day to day basis - and the 900Mhz HSPA does be a great help especially for in building penetration.
In my experience no network is perfect, I know of a Vodafone cell locally that has horrends data problems with 2G data in general being poor, Three is known to have congestion problems in many urban areas even outside of peak times (all networks can suffer from this in localised cases but Three are well noted for this problem) while in my experience EE's network is just not reliable enough for indoor coverage in the places I mainly visit. For me O2's network works out for me as the best all rounder, but for others EE, Vodafone or Three may work out better. |

If the fallback is to 3g900 then could we make a call then end it and before it goes up to 4g run a test, or am I just over complicating things
?

That sounds like limited MHz allocated to the 900 band.

More then likely they setup some QoS so the 4G users get first dibs lol

does DC-HSPA on O2 or Voda Use 2x5mhz on 2100 or can it use 900/2100 at the same time??

DC uses 2 lots of spectrum and aggregates them together.
So it would use 2x5 + 2x5. Requires 10Mhz in total. Not a problem on 2100 but as Redcoat says on 900 it wouldn't leave a lot for 2G since they only have about 17.5 Mhz of 2G spectrum I think. |

Unlike LTE where allocations can be as low as 1.4Mhz, 3G must be in 5Mhz slices so the minimum they can use on 900 is 5Mhz. So as I said before, let's say 5Mhz on Vodafone's 2100 is giving you 2Mbps, if you halved the frequency, then you should be getting at least some kind of usable speed even if it was 800Kbps or so. Hell, even if it was 300Kbps it would work, so it doesn't explain why the speeds like dial-up. Has to be backhaul. |

?LTE reselection after a call normally occurs in less than 5 seconds. On my iPhone on EE it can be literally 2 seconds after hanging up. |

I just ran a test 3.63Mbps down and 2.4 Mbps up on o2 H+
I'll see if I can run a 4g test later |
