AT&T has announced the next big step for its growing 5G network: nationwide availability. By the company’s own estimates, its 5G network is currently spread across nearly 400 U.S. markets and blankets just over 250 million Americans. As far as we can tell, AT&T thankfully isn’t including its controversial and misleading 5GE wireless coverage (which is basically just a fancy name for 4G LTE-Advanced) in its 5G declaration. Instead, AT&T says that its ultra-fast mmWave 5G technology is available in 35 markets. Its sub-6GHz “low-band” 5G spectrum is used to cover the rest of the nation (crucially, outside of large city centers). “With AT&T 5G reaching... Read more...
Qualcomm has rolled out the world's first fully-integrated 5G NR millimeter (mmWave) and sub-6 GHz RF modules for smartphones and other mobile devices. The new chips include the QTM052 mmWave antenna and the QPM56xx sub-6GHz RF module family. The new chips have a compact footprint, pair with the Snapdragon X50 5G modem, and deliver modem-to-antenna capability across several spectrum bands.  "Qualcomm Technologies’ early investment in 5G has allowed us to deliver to the industry a working mobile mmWave solution that was previously thought unattainable, as well as a fully-integrated sub-6 GHz RF solution," said Cristiano Amon, President, Qualcomm Incorporated. "With 5G, consumers can... Read more...
The race towards gigabit Internet continues as Google Fiber slowly proliferates and other ISPs work to catch up, but Samsung announced that it’s actually looking at gigabit speeds--for mobile devices. Indeed, Samsung says it has been testing a 5G mobile communications system, the eventual successor to 4G LTE that is capable of up to 1Gbps. The 5G technology, dubbed mmWave, runs in millimeter Ka bands and requires a “broad range” of frequencies but operates at 28GHz, delivering up to 1.056Gbps for up to 2 kilometers. It uses adaptive array transceiver technology with 64 antenna elements. (Image credit: variety.thaiza.com) Of course, this is all in the testing phase, so don’t... Read more...
