Samsung Announces 1 Gbps Wireless
While Pretending that '5G' is An Actual Thing
Samsung this week turned heads by announcing that the company had discovered the "world's first 5G mmWave mobile technology." The new technology is capable of transmiting data in the millimeter-wave band at a frequency of 28 GHz at a speed of up to 1.056 Gbps to a distance of up to 2 kilometers.
The shorter wavelengths being used traditionally weren't thought to be useful for wireless transmissions -- but Samsung is overcoming those problems using array transceiver technology with 64 antenna elements to tackle the weaker propagation characteristics of millimeter-wave bands.
"The implementation of a high-speed 5G cellular network requires a broad band of frequencies, much like an increased water flow requires a wider pipe," insists Samsung. "While it was a recognized option, it has been long believed that the millimeter-wave bands had limitations in transmitting data over long distances due to its unfavorable propagation characteristics."
That said, the company doesn't expect the technology to see commercial implementation anytime before 2020 for a number of reasons, most notable the battery power required to make this technology even remotely plausible. There's also nothing stated about the upstream side of the equation.
While promising, Samsung's also playing a little fast and loose with the term 5G, since no standard exists yet. Granted the abuse of the term shouldn't surprise anyone, given that the press, companies and even the ITU abused the term 4G
to the point where everything short of carrier pigeon and cans and string was technically able to carry the moniker.

Re: I want...
said by tshirt:I was just going to say that... I guess in 2020 we'll be back to bag phones with new and improved car battery and have to carry a LOS antenna with it.
Unfortunately, millimeter-wave band at a frequency of 28 GHz is blocked by air, except at extreme power levels, so your Portable phone will need a power cable the size of your arm, and the radiation will be on par with a radar gun/full body scan.
I hope they patent the hell out of it And license everyone but Apple.
Another example of lab experiment to marketing hype LTE and WiMAX can also do 1Gbps with enough spectrum. Backhaul to every cellsite is the real challenge.

said by KrK:I don't know why you don't see third-party cell sites. If you know something about it, why not share?
... and that's also an area where at&t and Verizon heavily abuse a virtual monopoly-like power.
This is simply why you don't see random third party cell sites, which if you think about it, would SEEM like a good business investment.
They would be, until you read up on why they aren't.
Recently AT&T was rumored to be thinking about selling some of its towers; see for example:
