I guess in the spirit of the VR Showcase thread. it's time for me to start posting news articles about 5G. feel free to contribute what you find online too. thanks.
here's what I found in 2 seconds.
What Is 5G?
We've only had 4G cellular networks for a few years, but all the wireless carriers are already talking about 5G. It's actually surprisingly easy to do so, because there isn't any official definition of 5G yet. What's happening now is that all the players in the wireless world, from chipset makers to carriers, are jockeying to be able to define 5G and establish themselves as 5G leaders.
So head with me down the rabbit hole that is 5G as I try to explain what the heck is going on here.
1G, 2G, 3G, 4G, 5G
The G in 5G means it's a generation of wireless technology. While most generations have technically been defined by their data transmission speeds, each has also been marked by a break in encoding methods, or "air interfaces," which make it incompatible with the previous generation.
1G was analog cellular. 2G technologies, such as CDMA, GSM, and TDMA, were the first generation of digital cellular technologies. 3G technologies, such as EVDO, HSPA, and UMTS, brought speeds from 200kbps to a few megabits per second. 4G technologies, such as WiMAX and LTE, were the next incompatible leap forward, and they are now scaling up to hundreds of megabits and even gigabit-level speeds.
What Is 5G?
5G is a new network system that has much higher speeds and capacity, and much lower latency, than existing cellular systems. The technologies to be used in 5G are still being defined, but there are some general themes everyone agrees on.
5G networks will use a type of encoding called OFDM, which is similar to the encoding that LTE uses. The air interface will be designed for much lower latency and greater flexibility than LTE, though.
The new networks can use frequencies as low as old TV channels, or as high as "millimeter wave," which are frequencies that can transmit huge amounts of data, but only a few blocks at a time. 5G may also bring in Wi-Fi as a seamless part of a cellular network, or transmit LTE-encoded data over Wi-Fi frequencies, which is called LTE Unlicensed.
5G networks are much more likely to be networks of small cells, even down to the size of home routers, than to be huge towers radiating great distances. Some of that is because of the nature of the frequencies used, but a lot of that is to expand network capacity.
So 5G networks need to be much smarter than previous systems, as they're juggling many more, smaller cells that can change size and shape. But even with existing macro cells, Qualcomm says 5G will be able to boost capacity by four times over current systems by leveraging wider bandwidths and advanced antenna technologies.
AT&T has also spoken of "edge intelligence" as being part of its 5G vision. With edge intelligence, the individual small cells have much more autonomy to decide how and where to route data, which can greatly lower latency.
The goal is to have far higher speeds available, and far higher capacity per sector, at far lower latency than 4G. The standards bodies involved are aiming at 20Gbps speeds and 1ms latency, at which point very interesting things begin to happen.

Verizon to be first to field-test crazy-fast 5G wireless
How fast is 5G? Verizon's tests have shown a connection speed that is 30 to 50 times faster than its current 4G network.
Ericsson showed a wireless radio link with prototype 5G networking technology at Mobile World Congress in March.
It expects "some level of commercial deployment" to begin by 2017 for next-generation wireless. That's much earlier than the common industry belief that 2020 will mark the start.
Verizon is getting ready to kick its wireless network up another notch.
The nation's largest wireless carrier will begin field trials on so-called fifth-generation, or 5G, technology within the next 12 months, Roger Gurnani, chief information and technology architect for Verizon, said in an interview last week. He expects "some level of commercial deployment" to begin by 2017. That's far earlier than the time frame of 2020 that many in the industry have pegged for the initial adoption of 5G technology.
The trials would make Verizon the world's first carrier to seriously move into 5G. It also represents an initial step toward the broader telecom industry radically transforming wireless service by adding significantly higher speed and responsiveness. Just as the move to today's 4G wireless technology drove an explosion of smartphone adoption and mobile services, 5G could similarly drive its own tech revolution.
"The future is going to bring more stuff that I can't really describe," Gurnani said. "We can't possibly envision the full range of disruptive products and services. But we have some possibilities."

5G networks are coming in 2020: here are the speeds and advantages to expect
I still remember the day when I first accessed the internet from a mobile device. It was in the early 2000's, when I owned a Motorola T720 flip phone. Its data connection allowed me to download ringtones, wallpapers, even games from the web, which was quite an adventure back then. But it was also kind of slow, and even a single image took a long while to load, even when it was the size of a postage stamp.
Today's 4G phone networks are literally over a thousand times faster, but even that won't be able to meet the demand for data traffic of future applications. That is why a whole new generation of cellular communications standards is already in development, and 5G isn't far from becoming the next hottest tech buzzword. But how did we get here and what is 5G going to change? Let us explain.
How fast is 5G, and what do we need it for?
At the typical data speed provided by today's 4G LTE networks (between 10 and 30 megabits per second in a realistic scenario), a high-definition movie can be downloaded in a matter of minutes. That is fast indeed, but when it comes to cellular networks, data speed is just one of the many factors to consider.
In the near future, our smartphones will not be the only devices requiring a 24/7 data connection. Self-driving cars, autonomous drones, IoT appliances, smart wearables, and infrastructure solutions are expected to raise the demand for cellular data, hence next-gen technologies are being developed with capacity in mind. In other words, 5G will be expected to reliably and simultaneously serve a much greater number of connected devices.
At the same time, 5G networks will be designed to be flexible, responding to the particular usage scenario. Some applications might require super-fast data exchange, while others may demand a rock-stable connection with minimum latency. No matter the case, 5G should be able to adapt and deliver the best possible user experience.
Actual 5G data speeds will vary from one application to another, but rates between tens of megabits and tens of gigabits per second are to be achievable. Overkill? By today's standards, probably. Awesome? Most definitely, yes! All of this extra bandwidth will allow the delivery of services that current 4G networks can't quite handle. Think 4K, 8K, 360-degree video streaming, real-time augmented and virtual reality experiences over the web, massive online multiplayer games with zero delay issues, and more.
