T-Mobile US has focused its 5G talking points around touting its nationwide 600 MHz spectrum portfolio picked up in an FCC auction last year ...
Millimeter waves – Miniature cell phone towers AKA small cells transmit data through millimeter waves. They are called “millimeter waves” because of their narrower than average wavelength.

In a mmWave 5G application, the simple fact of device orientation (holding it, in relations to cell site) can interrupt the millimeter waves. Therefore, multiple millimeter wave antennas are required and arranged in different orientations to ensure a clean signal. This is why most 5G networks will be deployed as ...
It also tapped Samsung as its equipment provider of choice. Verizon's over-the-air Internet service, which is based on high-frequency millimeter waves, doesn't require a clear line of sight between the transmitter and receiver, which was surely a relief. Samsung says a signal from a single radio can reach as high as the 19th ...

Based on 802.11ac standard 5G is actually an umbrella term, according to Ivan Seskar, co-chair of the IEEE 5G Initiative Testbed Working Group and IEEE Senior Member, that represents a multitude of technologies like millimeter waves, beamforming, small cells, massive MIMO and full duplex.
Millimeter waves cover the 30- to 300-GHz range. All sorts of systems use them, especially radar and satellite. The 802.11ad WiGig WLAN products at 60 GHz are now available. Automotive radars use 77 GHz. And many of the forthcoming 5G cellular and fixed wireless access systems use mmWaves.

The bottom line is millimeter waves can enable serious wireless broadband. This is also true for the licensed millimeter wave bands, as well. The second challenge comes from the attenuation -- that is, loss of signal strength -- that occurs in the millimeter wave spectrum at 60 GHz. Oxygen quickly absorbs ...
While this will certainly open up more real estate on the radio wave spectrum for the new services expected with 5G, it comes with the problem that these millimeter waves don't propagate through dense urban environments as well as today's networks. Today's 4G networks use bands lower on the radio ...
To increase the throughput of wireless networks, companies are expanding into higher spectrum bands than ever before to connect everything from smartphones to cars to the internet. The problem is that these millimeter waves can be blocked by buildings and trees and absorbed by oxygen over long ...
Instead, they're focused on the home broadband market, delivering what's known as fixed wireless service over millimeter waves. Millimeter-wave spectrum is freely available for 5G for a reason—it has terrible signal propagation. Any obstacle in a signal's path, including rain, trees, and people, can disrupt it ...
Cities can choose early deployment of wired technologies rather than adding millimeter waves to the already dense electromagnetic environment. In doing so, they will also expose their citizens to fewer security and privacy risks, retain more community wealth, enjoy more local control, and avoid liability for ...
It was widely assumed that emulating millimeter waves was, for all intents and purposes, impossible. Prior to 5G development, standard industry procedure was to use channel emulators to quickly gather a large amount of general data on the technologies being developed, before conducting more refined, ...

First, the network transmits data using millimeter waves with a frequency over 20 GHz, which enable data transmission 100 times faster than existing WiBro backhaul networks. Backhaul networks work as intermediaries, linking receivers on the trains with the public Internet, via radio towers along the tracks.

Communication in 5G networks will be driven by high-frequency millimeter waves. A general 5G cellular network would connect mobile users to a base station, which would be connected to the core network. Although low latency radio interfaces would provide sub-millisecond communication between the ...
The final architecture of 5G cellular networks has yet to be carved in stone. However, it looks as though millimeter waves, with their ability to obtain wider bandwidths, will play an important role in 5G—the next generation of mobile phones. The combination of these bands along with directional phased-array ...
Using computer modeling, optimization software and complex algorithms, the team set out to build metadevices that could bend or focus millimeter waves but that avoided problems with conventional approaches, such low efficiency, narrow bandwidth and the bulkiness of the devices. "What we've achieved ...
Last year, Verizon tested high-frequency millimeter waves for fixed wireless service, which it is now preparing to roll out commercially in Sacramento.

5G likely will use the existing mobile spectrum space and extend it by also tapping higher frequencies, called millimeter waves because they're 1 to 10 mm long. Millimeter waves can carry more data but travel only short distances. So they'll require many small base stations to receive signals and send data.
In October, Qualcomm unveiled the X50 modem as the first chip capable of connecting to the millimeter waves used in 5G networks. Just last week, the company touted an extensive list of partner companies set to use the X50 in their devices, along with carriers that will use it in their 5G testing this fall.
