AT&T said its users can expect "a better mobile experience" in the city, with technology it's been working on for over a year that combines both permanent and temporary upgrades to the carrier's cellular connectivity. The company's $40 million investment in its Minneapolis wireless network boost includes coverage within the U.S. Bank Stadium (where the game will take place), as well as outside the stadium in hotels, airports, and other venues that will see increased traffic in a few weeks.
- Upgraded in-stadium Distributed Antenna System (DAS) offering "nearly 220% more LTE capacity."
- More than 800 hidden antennas in the stadium to help manage wireless traffic.
- DAS installed at 16 total locations in Minneapolis.
- 10 Cell on Wheels (COWs, or temporary towers) deployed to further support reliability of AT&T's network.
- 5G Evolution with 256 QAM, 4x4 MIMO, and 3-way carrier aggregation in select areas on supported smartphones.
- 24 new permanent cell sites and more than 230 permanent small cell sites.
- Introduction of LTE Advanced features to 4G LTE network "for greater capacity and faster peak data speeds."
- Addition of 48 percent more antennas to DAS inside stadium.
- New neural host DAS in Mall of America to boost network capacity by 900 percent.
- Similar system added to Minneapolis-Saint Paul International Airport to boost network capacity by more than 1,000 percent.
- Boosting network capacity 30x in U.S. Bank Stadium, 35x in the convention center, and 16x in Xcel Energy Center.
- Doubling the amount of LTE spectrum in the Twin Cities, along with carrier aggregation, 256 QAM, and 4x4 MIMO.
- Deploying more than 120 small cells across Minneapolis and surrounding areas.
- Increasing upload speeds up to 40 percent inside the stadium with Centralized Radio Access Network (C-RAN) technology.
Although it won't launch in time for Super Bowl LII, T-Mobile has also provided more details on its own plans for a true 5G network, while commenting on AT&T's "#Fake5G" debut in 2017. T-Mobile said its schedule for 5G hasn't changed, and is still on track to debut nationwide by 2020. The company said it's been "encouraged" by confirmed chipset and OEM plans to launch wider support for 5G smartphones in 2019, which will initiate broad support for a "real 5G" network.
