5G networks could help connect new sensors such as balloons used in scientific research.

Current to make 5G high speed networks a reality, AT & T will illuminate New Orleans, Houston and San Antonio, Texas; Jacksonville, Florida; and Louisville, Kentucky with new generation mobile technology this year.
The cities will join other cities already announced: Atlanta, Dallas and Waco, Texas; Charlotte and Raleigh, North Carolina; Indianapolis and Oklahoma City – the company said Monday at its Spark event. Patches of some major cities will see 5G in 2019: Las Vegas, Los Angeles, Nashville, Orlando, San Diego, San Francisco and San Jose.
Still on the show, AT & T said its 5G network was mature enough to call a handset using a 5G chip from the next version of Qualcomm.
"We have established a connection between this test device and the production network we are building," said Gordon Mansfield, vice president of Converged Access and Devices at AT & T.
You might already be exhausted by the 5G hype, but that could really mean a major change in our lives. It should enable faster and, perhaps more important, faster data speeds, shorter communication times that can enable technologies such as mobile gaming, car-to-car communication and augmented reality. The first version is expected to arrive in 2019, but subsequent incarnations of 5G technology should extend it to smart traffic lights, smartwatches without too much energy and broadband home. .
AT & T is fighting against Verizon, T-Mobile and Sprint to expand 5G mobile networks as quickly as possible. There are not many ways to stand out from the competition and switch providers, but network transitions offer a chance.
AT & plans to bring 5G coverage to 12 US cities (blue) in the South and Midwest in 2018, then to a portion of seven cities generally more populated (red) in 2019, the year when 5G phones are expected to arrive.

Fast but not so fast
the parade The first 5G shows how eager carriers are to capitalize, but it's better not to get too excited. AT & T 2018 networks will only work with mobile network devices that send your phone or laptop data with free Wi-Fi. The partial coverage in 2019 will not be useful if you do not live or work in the right places. And of course, you will have to buy a new phone.
AT & T's 5G will first use "millimeter-wave" connections – high-frequency radio waves that have been largely untapped until now, as it's hard to send a signal very far through the walls and even the air.
"It does not spread far, but it bounces and reflects well," Mansfield said. For a place like Times Square in New York, "you can cover this whole area with only a handful of strategically placed nodes," he said. The millimeter wavebands are sufficiently streamlined to provide sufficient bandwidth for fast data rates, he added.
Subsequently, AT & T will add 5G connections to lower radio frequency bands. This will support 5G in the suburbs and rural areas.
In another step in the race, Sprint and Nokia network hardware manufacturer announced that they had 5G connections using an antenna amplification technology called massive MIMO – multiple inputs, multiple outputs. Companies will demonstrate at Mobile World Congress Americas in Los Angeles.
AirGig enhancements

AT & T also announced a new step towards the commercialization of the technology called AirGig, which could help broaden broadband Internet access. AT & T's AirGig grafted to power linessaid Mansfield, putting inexpensive antennas every 100 or 200 meters and channeling data along the road at speeds of several gigabits.
AT & T has tested AirGig in Georgia, but is now in "advanced discussions" with manufacturers who will start manufacturing and testing AirGig equipment, he said. "We will probably move on to another series of trials with other features that have progressed in the labs," he said, as these tests are highly likely in 2019.
Fireplaces do not connect directly to the AirGig data stream, but AT & T plans to periodically put wireless stations along the route providing last-mile connections. The idea is to reduce the cost of connecting homes compared to fiber optic lines, which are quick but expensive to bury the ground or string along the telephone poles.
"Getting fiber optic everywhere, especially in rural areas, is very expensive – if you could already use the power grid, you can cut costs faster than existing fiber optics." roads, "said Mansfield.
