They did.... DC-HSPA+ is classed as 4G

DC-HSPA+ is not a 4G technology, the ITU did not say it was, that was T-Mobile USA being silly.

I do find that O2 has excellent 3G coverage in Hampshire and on the train now, I think they may be giving EE a run for their money UK-wide soon!

Did you even read the link?

They announced in December 2010 and then January 2012 that DC-HSPA+ can be classed as 4G.

I'm not making this up. It's right there in black and white.

At the end of the day, EDGE comes under 3G according to the ITU and DC-HSPA+ comes under 4G according to the ITU.

As mentioned on the previous page, EDGE is an evolution of 2G and deployed on 2G sites, DC-HSPA+ is an evolution of 3G and deployed on 3G sites. Even though the ITU classes them differently.

No EDGE is 3G, it is classed as such by the ITU. GPRS is 2.5G.

If EDGE was 2G it would say so on the websites of O2, etc.

No.... UK networks class EDGE as under the 2G umbrella. In the same way that we class DC-HSPA+ as 3G.

Here is what O2 say themselves. So I'm not sure where exactly you're getting your information from.

“If you have chosen the £10 Big Bundle, you can use O2 UK's 2G (GPRS and Edge) and 3G data networks when using your inclusive data allowance.”

O2 quite clearly define EDGE as a 2G technology.

I really can't comprehend why you're not able to understand this? It's not hard.

The ITU class EDGE under 3G spec and DC-HSPA+ under 4G spec. Whilst the definition can be said to mean it's 3rd generation (in terms of providing similar speeds to UMTS, the actual technology is not.

In terms of actualities, EDGE is an evolved version of 2G tech and DC-HSPA+ is an evolved version of 3G tech.

O2 class 2G as GPRS, EDGE is not classed as such.

DC-HSPA+ is also not 4G, it's very clearly 3G, which by the way O2 also support on all of their network, unlike some other networks...

Are you trolling now?

It says in my post above that EDGE is 2G. direct from the O2 website. Also O2 don't have DC-HSPA+ on "all of their network".

I give up....

O2 does have DC-HSPA+ on their network, I usually get at least 10Mbps on 3G, 30+ on 4G.

On Three (if I have a signal) I get maybe 2 on 3G and 10 on 4G - 4G being incredibly rare as the roll-out is so slow.

Three need to increase the money being put into their network ASAP otherwise they're going to be left behind...

I like how you've failed to admit you're wrong. What is it with people on this forum and not admitting when they've got something wrong.

Three's 3G speeds are terrible, as is their 4G coverage, even in central London it's spotty. The same cannot be said for O2 which has 4G all over London and in Hampshire.

And I'm not wrong, EDGE is a 3G technology.

EDGE is 3G! You yourself are wrong, everybody else disagrees with you.

EDGE is 3G, 2G is GPRS, 4G is LTE, etc.

Why are you so hard to convince?

If you agree that the ITU defines EDGE as 3G then you should also agree that the ITU define DC-HSPA+ as 4G. You can't pick and choose what to believe.

Also you still haven't answered my question about O2? You said without a doubt that O2 class EDGE as 3G. Yet they don't. So can you please provide evidence where they do?

When will Three roll-out more 4G? They're miles behind O2 and Vodafone. They're going to continue losing customers if they don't invest in their network soon.

On an app for my old Windows phone it used to display:

EDGE = 2.5G

HSDPA = 3.5G

Yeah HSPA was 3.5G, UMTS was 3G as we came to know it and was used on 2100MHz.

Regardless if EDGE is 2G or not, I will do better tests later over a longer period of time. From what I have researched 2G is better to use when the dominant use is calls/standby. 3G/4G better when dominant use is internet. I think its silly for people to tell me to get a 10 year old phone just because I want to be power efficient on my device.

What I will probably do is automate the change as manually adjusting is annoying, I will use tasker to enable LTE when I turn on mobile data, and to enable 2G when mobile data is turned off.

MY signal strength on LTE is 84%, and its 99-100% on EDGE.

I think you should do your research, EDGE satisfies the requirements for a 3G technology . There is no argument about that.

The issue here, is how the networks market it. Clearly, in the UK service providers marketed it as an extension to existing GSM networks and we habitually associate 3G with UMTS.

Part of the issue here is the use of wooly language like "classed as" - that only makes sense if you define who is making the distinction and on what basis.

In the US the situation can be even more confusing as some service providers have been using the term 4G (for marketing purposes) before it was even officially defined. Leading to some technologies being associated in the publics mind with 4G whereas we would consider them to be 3G.

Fact is the UK networks class Edge as 2G and everything above is either 3G or 4G. Edge is also similar to GPRS in battery drain. That's all that matters.

Do your own research and try reading first.

EDGE is 3G, if an operator chooses to market it otherwise that is their call.

Take your own selection of handsets, various makes and operating systems. On all of them turn off 3G and 4G. You will still connect to EDGE signals (E or EDGE symbol) as well as GPRS. Something like 80% of smartphones use a Qualcomm radio chip and in 2G mode these chips connect to EDGE signals.

The confusion is the ITU have been "led" my marketing departments (mostly AT&T in the USA) to use the terms "3G" and "4G" for *data throughput* speeds. I suspect its all caused by Apple because the iPhone doesn't show the different 3G modes (3G, H, H+ etc) - so AT&T got Apple to show the 4G symbol on the iPhone 4S for any cell site with HSPA+. This started the insanity. (With a UK SIM card, in the US, iPhones show 4G for LTE to really confuse !).

EDGE in the UK hardly ever gets any faster than 50kbps on Voda or EE. However in the USA I've seen 120kbps on T-Mobile EDGE. (Similar to ISDN dual channel).

Technically speaking you are correct in relation to EDGE, however Jabba is right in respect of DC-HSPA, ITU have allowed the technology to be classed as 4G. In practice most operators worldwide didn't follow T-Mobile USA's lead. Looking outside of the USA market and you will find DC-HSPA classed as a 3G technology, I don't think there is a network in Europe that has classed it as 4G mind you.

If we ignore the technicalities then I think you are very much correct. Fortunately European networks have avoided confusing legacy and modern technology. At the moment there is a fight surrounding the terminalogy of carrier agregation between EE and Vodafone, eventually that will settle. I am thankful that networks here have avoided confusion and generally making things a bit more clear.

Having worked in the industry EDGE was always referred to as a 2G technology, when O2 got first dibs on the iPhone it more or less upgraded its entire network to EDGE within the space of a few months. 3G technology and its varients only really began to find its feet in this country when MBNL was setup with the target of expanding the availability. For a period or 12-18 months Orange and MBNL operators were tusseling ober who had the widest coverage (even though measurements weren't the same it was recognised MBNL has the largest).

However though I have went off on a tangent, point remains 3.75G or maybe 3.9G DC-HSPA has been allowed to be classed as 4G, yet most networks world wide recognised it wasn't really in spirit but more a play on words. I think there is some arguement that LTE isn't true 4G either (though I will defer to Jabba's better judgement on that one).
