Sprint is still running tests to see what kinds of speeds people can expect when they attend the Super Bowl at Mercedes-Benz Stadium for the big game on Feb. 4, but suffice it to say its network will be able to carry more people at high speeds, so the average user experience will be more consistent. Latency—a key tenant of 5G—is improving with Massive MIMO, but it will get really “fantastic” when 5G gets rolled out, she said.The infrastructure in Atlanta is being supplied by Ericsson, and the small cells are coming from a variety of vendors. Sprint has also doubled network capacity at Hartsfield-Jackson International Airport and is providing service for the Metropolitan Atlanta Rapid Transit Authority. Major traffic corridors have been upgraded with tri-band gear: 800 MHz, 1.9 GHz and 2.5 GHz, and it’s installing Massive MIMO on those sites. Dozens of small cells have been deployed for more capacity downtown, and distributed antenna systems (DAS) have been added to key hotels.These are split mode radios that are capable of providing both 4G and 5G service, with 128 antenna elements. That compares to the typical cell site equipment that has only eight transceivers and eight transmitters. And even though they’re called “massive,” they are far from it, she said. “It’s actually smaller in size than our current 2.5 deployment,” and the radio and antenna are combined into one box, making them more aesthetically pleasing—and generally better accepted in most jurisdictions.Atlanta will be one of the first commercial 5G markets for Sprint in the first half of this year. “That’s not a coincidence,” she noted. As part of Sprint’s strategic planning for 5G, it considered the Super Bowl, the size of markets and more. “It’s not a coincidence we have Massive MIMO ready for the Super Bowl and that Atlanta is one of our first markets. This is very intentional” and shows the extent of investment it’s making in Atlanta.It’s worth noting the upgrades are designed to be permanent, so residents will get the benefits long after the big game is over. Of course, it’s anybody’s guess what happens if and/or when T-Mobile’s combination with Sprint gets approved and executed, but Sprint until that time has to act as its own entity, and the plan is for the upgrades to stay put. The 5G part does require 5G-capable phones to use the 5G signal; Sprint will launch 5G phones this year, but it’s not saying anything more about that now. -- ???????? | |||
