With 4G/LTE underway, Nokia and NTT DoCoMo talk about 5G
posted by Maxwell R. / Apr 24, 2014, 8:55 PM
While we refer to LTE service as “4G,” there was controversy for a while as LTE, in its current form, does actually meet the standards that have been established as 4G. The ITU-R standards body later bowed to the marketing pressure, and that is why we saw WiMAX, LTE, and even HSPA+ referred to a 4G.
LTE-Advanced meets the true definition of 4G and as such, the insiders refer to LTE-A as “true 4G.” Since LTE-A is already seeing commercial deployment, eyes are already starting to look at what is next. What is in store for us with 5G?
As it happens, the standard for 5G is not yet defined, but NTT DoCoMo CTO, Siezo Onoe, discussed the next generation of wireless communication at a conference in New York, dubbed the “5G Summit.” Since the LTE standard we enjoy today was originally proposed by NTT DoCoMo, when the company has something to say about what might be next, people tend to listen.
Mr. Onoe, along with Nokia Solutions and Networks VP of research and technology, Lauri Oksanen, said there is still a great deal of work to be done just to reach a definition of what 5G will be, but there are some things they both expect to see written into the specification.
5G will most certainly operate with much higher frequency bands and utilize millimeter wave radios. This is based on the expectation that providers will simply need access to more spectrum. With higher bands though (think 28GHz and above) comes the requirement for more densely arrayed antenna systems.
“Early tests have shown that it is possible to build a [millimeter wave] small cell network with the nodes roughly 100 meters apart,” according to Oksanen. However, according to Onoe, “If we deployed that many small cells, we may have some problems, even in Japan,” such as, access to enough fiber optics to handle the backhaul.
That means 5G will definitely have some spec requirements related to the physical facilities on the back end. 5G will have a more comprehensive multi-frequency standard as well, since the lower frequency bands will eventually migrate to the new standard and will be needed for the same reasons they are desirable now. Machine-to-machine communication will be in the picture as well.
Onoe believes the year 2020 may see the first launch of 5G and we may begin seeing testing of the technology as early as 2018. Lab tests of some of the ideas slated for 5G are already being conducted according to Oksanen. There has been no defined data speed set as of yet, but measurements in the realm of gigabits-per-second are part of the conversation.

people arent satisfied with 4g? sure 5g will come as all things improve with time but im in no rush for it

Well with the industry going for higher resolutions, we'll need faster network speeds to get us that higher resolution content even in the same time frames we have now. I'm sure by 2020, 4K (or even higher) will be normal for smartphones and tablets, and it would take about 10 minutes to load a 5 minute 4K YouTube video at 20 Mbps, which is what I think to be an average LTE download speed. You can just forget about movies, that would take ages. Yes, it isn't needed currently, but by the time it actually rolls out, we'll be throwing money at our networks to give it to us because we want our 4K videos to load in less than 5 seconds.

I thought NSN tested it's flex multi radios using 60Mhz spectrum with LTE-A (using 3 20Mhz channels and carrier aggregation) and got speeds exceeding 2Gb/s! Speeds this high will make little difference to end users, YouTube and everything else will run no smoother... Maybe if consumers are replacing home broadband or even full streaming TV, but any of this technology will still be mainly suited to urban areas and if 5G needs radios every 100m... it will not only be costly, but also difficult to get all the zoning & permits. We'll see what time will hold by 2020.

lol still doesn't matter if they limit your data usage. "2 gigabytes a second but only allow 6 gigabytes a month. Enjoy your 3 seconds of internetz"

I've pulled 41 Meg speeds before. With T-Mobile's unlimited data, don't have any problems.

You can thank ATT & Verizon, the duopoly that controls most of the US wireless market, for this paradox. They make a lot of money selling data -- and data overages. There never will be affordable unlimited bandwidth from either of these two companies.

Take your social justice somewhere else dude. I may not have unlimited wireless data, but my U-Verse with AT&T is bringing me 40+Mbps reliably. I pay $65 per month. All my phones and computeres connect. My phone finds Wi-Fi almost everywhere, most of it AT&T hot-spot (unlimited btw). Can Sprint or T-Mobile do the same? Oh wait, no they can't because they have no telco assets. There's already a price war going on, and don't pretend T-Mo and Sprint are some helpless babes. T-Mo's parent Deutsche Telekom is worth $100B+ and Softbank is worth about $50B+ ...there are no hobos in the big wireless game.

meanwhile in the Philippines, we have the slowest internet connection in the southeast asia region - average 2mbps speed on 4g LTE

you'd be lucky to get 1mbps on Sprint's 3g network.
