NFL football is big business with team owners spending millions and millions of dollars on single players and raking in millions and millions of dollars in profits each year. With so much money made and spent in the NFL, it's natural for teams to want seriously high tech stadiums for their teams to play in.
One of the newest and most high tech stadiums in the league is Levi's Stadium where the San Francisco 49ers play. The stadium has a very robust wireless infrastructure that will allow the over 70,000 fans that can fill the stadium to all connect to Wi-Fi and 4G networks.
The stadium has 400 miles of cabling inside and 1200 distributed antenna systems for Wi-Fi. The stadium also has an internet backbone that offers 40 gigabits per second of bandwidth, which is 40 times more bandwidth than any other stadium. The stadium also has 1700 beacons to give people directions within the stadium. Other tech features include 2000 Sony TVs and 70 4k TVs in addition to a pair of giant LED displays in each end zone.
