Which countries have 4G?

Are we quite far behind with 4G technology, or is it relatively new?

After doing some research to write article about it, which never materialized, I only know of Verizon LTE network on 700Mhz band in US that can be called 4G. While it's not a real 4G network as it meant to be, it gets quite close. Don't know what actual speeds are, but they seem fairly quick to be considered next generation. Major difference between HSDPA+ and Verizon LTE is latency. Internet communication feels very responsive and its sometimes difficult to believe you are on wireless. Feels like you are on WiFi. Since most of the time phone pulls 5-10KB packets at regular intervals latency becomes more important than bandwidth.

If you go to wikipedia and search 4G, you'll get loadsa info.

I'm posting this from a phone, so I keep this short.
Actually, 4G is not a well/firmly defined standard.
Some contries' 3.5 G is on par with some US networks' "4G"....

Frankly, I don't care much. As long as coverage isn't 100%, "potential" speeds are meaningless...

Jan's right, even LTE isn't true 4G, only LTE Advanced meets true 4G speeds.

As for HSDPA+, that's sort of 3.75G...at best...the term 4G is thrown around way to much. Word is, OFCOM in the UK, won't allow anything below LTE to be branded as 4G.

In the US it's a bit of a free for all, anything over standard HSDPA can be legally banded as 4G, even when it clearly isn't, technology or speed wise.

In fact, the ominous DARPA thought up the dream of "4G" for better military communications.... oh *cough* feck, Robin....

GPS, which helped breed Sat-Nav technology, was a military thing too. It's surprising how much consumer tech originates in the world of war or sport.

CTPAHHIK (god that's difficult to write out :p), having not been to the US since they developed their 4G networks I've never experienced 1st hand, the differentiation in latency between WiMax, HSDPA+ and LTE. How big is the difference?

I can help you with the official speeds that 4G has to be able to achieve before it can officially be classed as 4G.

High Mobility (cars, trains etc): 100Mbp/s down
Low Mobility (walking, jogging etc): 1Gbp/s down

So LTE, (as in the type you can currently use in the USA), is a very long way off fulfilling the true definition of 4G.

Latency is key. Even a 20 MB connection can feel slow if your ping is in the hundreds.

I wonder if there's a limit to how fast you can get a 3G connection (latency-wise), because I'm sure a lot of people would prefer a solid, nationwide, stable 3G connection, than a spotty 3G connection here and there, then the odd place with 4G.

matt101101 / MOD  Sep. 12, 2011 at 21:38

Blizzard, my HSDPA (Nottingham, UK, T-Mobile), pings around 85 to 100m/s on average. I don't know how fast that is in 3G terms. It's pretty slow compared to my broadband which is sub 20m/s pretty much every time, even when it's being a b*tch. What's your 3G like? And I agree, I'd rather have a quality 3G network with 99.99999% coverage than a patchy 3G/4G network like with have with 2G/3G atm.

matt101101 / MOD  Sep. 12, 2011 at 21:44

Decided to do a ping test on my Virgin Broadband, apparently 15m/s is pretty good, well it tells me I have an "A" grade line.

4 bars @ HSDPA - 1.5 Mbps down/ 0.4 Mbps Up, 164 ms Ping
In other words, serviceable, but pretty rubbish. I get a lot better results in the town centre.

matt101101 / MOD  Sep. 12, 2011 at 22:13

For some reason when I go to one of the suburbs of Nottingham I get HSDPA+, I posted a question about it the other day. I have no idea why I get it, I didn't realise we had HSDPA+ in the UK? I get about the same download speeds as you, but faster ping. I can just about stream a 720p YouTube video...on a good day...

CTPAHHIK  Sep. 13, 2011 at 08:15

Speeds and latency are dependent on network load. It would be great, if latency is not affected and only speed becomes slow.
Here are 3 UK results from same place @ different time:
21/8/2011 10:43 PM GMT
188.29.17.238
5.02 Mb/s
1.47 Mb/s
62 ms

1/9/2011 8:20 PM GMT
188.28.139.118
0.54 Mb/s
0.11 Mb/s
151 ms

@matt101101
I have never used WiMAX. On Verizon LTE I only had a phone and not USB dongle. Latencies were around 30ms - 35ms. I could not do a proper bandwidth test as you need a laptop for that. Keep in mind that it's brand new and only a few phones support it. There is no load on the network right now. It might be quite different a year from now and could be just as slow as 3G.

CTPAHHIK  Sep. 14, 2011 at 11:59

@matt101101
I have 17ms with O2

matt101101 / MOD  Sep. 14, 2011 at 13:57

Broadband, not 3G, I assume with a 17ms ping :)?

CTPAHHIK  Sep. 14, 2011 at 17:06

Yes, obviously, broadband.

blizzard7  Sep. 14, 2011 at 17:38

30ms is enough for a fairly good gaming experience. Then again, as you said early days. Cheers for the info.

Use of 3G kills my battery time (e.g. by around 50%). I would love the extra speed but not worth it if i'm not going to want to use it. I.e. I always tend to disable data on my SGS2 cos I would rather get an extra days use out it. Besides, I am never too far away from the internet anyway!
