According to Apple, O2 UK supports VoLTE.

That does mean a lot of users without VoLTE would lose 800 and that could be devastating.

If only we could turn back the clock and make it so data and voice was independently shown, so 4G could have been full power from the off.
People could see when they had gone beyond 2G or 3G for voice, and as time went on and handsets got VoLTE, the voice coverage would exceed. 4G sites could have been full power from day one. |

4G came just in time to many dense urban areas; if 3G was the data layer today, I would suggest extreme congestion in certain areas.

Or just not release 4G/LTE until voice was actually ready?

With 2G900 and 3G900 covering more areas than 4G800 VO2 SHOULD be fine for full power 4G800 as long as they add the SIP9 flag to all legacy sites that may cover the same areas as 4G800. This should allow VoLTE on applicable handsets while still supporting CSFB to 2G and 3G legacy layers for non VoLTE phones.

Yeah, I wondered this. My 3 Sim often shows 4G but will ring no problem and hop back to 3G if it's there. Why are we of the assumption that VO2 4G800 can't do the same? Or is it the fact that 800 might go a bit further than 900 and you may be in a position where you go to make a call with a signal showing (800) and as there is no 900, it won't work? That would be pretty rare I would think and even then, in marginal areas, people are used to calls not connecting / having to climb a tree etc.
This has the issue that the 3G900 becomes immediately swamped and so has it's coverage footprint on minimum most of the time. Hence the reason 4G800 is on a lower power than it could be. VO2 will have their 4G800 on a low power for some time. Three will as well as they just don't have the capacity. The only network who will be running it at full power is EE. |

Yeah I think that's the issue. They are not doing CSFB to 2G, they are doing it to 3G900 hence why they are rolling that out at the same time. Probably because their 2G kit is legacy and not compatible with CSFB. (This is exactly the reason EE are doing the 2G refresh but initially are doing CSFB to 3G as well)

I am correct to assume that 4G can only happen where there is fibre? Obviously in areas where dishes are allowed that's another method, since we only have Telegraph pole masts allowed because of restrictiions.

O2 speed tests
Just a speed tests, I must say I'm impressed so far....
https://www.dropbox.com/s/5trk8t0vz9...%2013.png?dl=0 https://www.dropbox.com/s/3qtrtkxbtq...%2057.png?dl=0 O2 800 only.... I'll get some day time tests tomorrow and upload. |

O2 Capacity Approaches Video: Six sector masts, 4G 1800MHz, microcells, O2 WiFi
Quite clever use of the spectrum |

Does O2 have a way of doing speed tests without using up data (like Vodafone's Net Perform app, or EE allowing Root Metrics tests)?

Quite clever use of the spectrum The shark fin antennae on the O2 store is receive antenna for the in store 3G2100 microcell - there is a fibre fed 4G800 microcell in there too. The other lamppost site you mentioned (if it's the one on Madeira Drive opp the Pier) is 3G2100 only. Hope that helps! 😊 |

I find it strange that O2 are using that outside fin antenna as a U21 receive antenna, yet they are having L08 run by fiber...
Correct me if I'm wrong, but isn't the backhaul available for the transmitted U21/L08 (for the microcell) dependent on the backhaul it receives? So the L08 will be fine as it is through fiber, but the U21 speed will be dependant on the speed of the U21 outside the shop... which not only will vary as the load on the receiving macrocell throughout the day varies, but also it will be dependant on signal strength, as 3G speeds get slower (by quite a bit) as the signal decreases. Wouldn't it have been better to route the U21 through the same fiber as L08? Because the L08 speed is dependant on the backhaul of the fiber (anything from 50Mbps to 100Mbps+?), yet the U21 speed will depend on what U21 is like outdoors, which won't be much more than about 5Mbps in a congested city? Assuming that the fiber would be good enough to support both U21 and L08, that is. |

They probably had the 3g 2100mhz fin in place long before 800mhz 4g came along, probably just left things as they were,

That's correct - the 4G rollout is seperate to the legacy 3G install and has been overlaid. Why pay to replace a working repeater solution with a new microcell - it's all about cost of replacement.
