Companies such as Nokia and Samsung have only reached 10Gbps and 7.5Gbps downlink speeds in their current 5G network tests, but the International Telecommunications Union (ITU) is taking things to the extreme by dictating that download speeds for a single 5G cell should reach 20Gbps. Real-world data rate, however, should see download speeds of 100Mbps and upload speeds of 50Mbps.

The total download capacity for a single 5G cell must be at least 20Gbps, the International Telecommunications Union (ITU) has decided. In contrast, the peak data rate for current LTE cells is about 1Gbps. The incoming 5G standard must also support up to 1 million connected devices per square kilometer, and the standard will require carriers to have at least 100MHz of free spectrum, scaling up to 1GHz where feasible. These requirements come from the ITU's draft report on the technical requirements for IMT-2020 (aka 5G) radio interfaces, which was published Thursday. The document is technically just a draft at this point, but that's underselling its significance: it will likely be approved and finalized in November this year, at which point work begins in earnest on building 5G tech.
 
Something doesn't compute. If real world speed would be 100mb in and 50 out that differs in almost no way from the current 4G I have (120Mb/s in and 35Mb/s out).
 
Under ideal circumstances, 5G networks should offer users a maximum latency of just 4ms, down from about 20ms on LTE cells. The 5G spec also calls for a latency of just 1ms for ultra-reliable low latency communications (URLLC).

What are ideal circumstances? 1 User 2 feet from the cell? Honestly I'm just outright calling bullshit on the latency, especially with LTE being used as an example. I have never once seen LTE approach 20ms, I have never once seen LTE below 500ms. Hell on Average I see LTE being more 1500-2000ms no matter where I've been in the country. 1-4 ms My ass.

Upload speed is terrible, although I don't really need it so it's ok. There's a decent ping.

Here's the best ping I've gotten based on the tests I have saved on my phone.

The worst ping was 75ms out of my tests.
 
No way will they get 1ms latency. You'd have to hardwire your phone to the cell tower.
 
It's going to be expensive I'm talking 100.00 a month at first with a .99 cent phone plan for 3 years.
I'm dabbling in the Cell Phone thing but really it's out of my league. 500.00 a year is just too much for Pokemon Go and a few calls.
 
This is the best I can get where I live. It's on AT&T. Verizon is not any faster though.

Yeah I agree. I would love a lower latency. To me it's more important than download speed. I already get 10mbs where I live down (up is like 2 to 3). Just lower my ping will ya?
 
Carriers: "That seems difficult, how about we just modify the '5G' marketing term so that it's something slightly different and do a little bit faster 4G?"


They've done it every time. We'll see "5G" marketed before being anywhere close to the standards set.
 
Most people don't realize that the problems with latency and speeds on current LTE system is not LTE spec itself but 1. weak or insufficient backhaul at towers and 2. Over capacity. You would be amazed how many cell towers are still using old T2's or T3's for backhauls. Some even don't have direct backhuals and rely on a mesh backhaul from other towers that are close to or over capacity. This is will not change with 5G and you will never see the true potential of the technology.

Pretty much the same thing with home broadband. They do not upgrade the backhauls or nodes and just keep throwing more subscribers on them so the can keep increasing profits. This is one of the main reasons you're seeing a rise in the use of wired data caps.

don't try to bring logic and technology into this argument. That isn't allowed. Also where do you see T2s? T1 and oc3s are normal, but never seen anyone use a T2.
 
I'm guessing wireless connectivity being the norm for all internet connections is the ultimate end goal. Rather like how cell phones have almost entirely replaced landlines for voice calls. Even most power transmission will possibly be wireless one day.

I've got a small cell right outside my office window on the next building over. AT&T LTE 37ms latency. It'll get worse once all the students wake up.

The concern right now is reducing latency. Speed increases and data rate changes will happen in later categories. It's kind of similar to how Cat 10 LTE will allow five carriers to be used at once compared to 9's three or how some Cat 13 devices should be able to last years off of standard batteries due to reduced bitrate requirements.
 
I just did a speed test on my mobile device while riding in a car and got this

Well students are all here and bustling about. latency is 36ms vs 37, download speeds went from 30.18Mbps to 2.37Mbps though. Uploads went from 4.88 to .29. Ah saturation.
 
Speeds and latency I get right now in the rochester NY area on Verizon LTE.

Using App
Ping - 70ms -
Upload - 0.46
Download - 1.02

Network around here sucks and only 70ms? Color me skeptical..So I did speedtest using the browser set to non mobile non flash.
Ping 500-750ms - I did a number of tests.
Speeds 1.2mbps - 3.4mbps - Seriously, fuck this network.

No point in listing individual uploads and downloads..it is damned abysmal. LTE my fucking ass.

edit: Before anyone thinks it is my device..wifi speeds are fine.
20ms ping
100 down
5 up

I wouldn't call that the fault of LTE but the network itself. I know that fixed wireless can get 5 - 10ms ping times. So I would expect that LTE or 5G being used for a deployment to a house vs your cell phone would be much more stable and get you better latency.

How old is your device? Because if it does not support Verizon's LTE advance network I'm not surprised at the speed. It's not 2010 where's no one's using LTE, the majority of their users are on it now, so the only real relief is to use carrier aggregation which is all they are doing anyways.
