When the Golden State Warriors and the Cleveland Cavaliers tipped off earlier this month in front of 20,000 fans at Oracle Arena, there were at least 20,000 (likely more) wireless devices in the audience. Those lucky enough to have scored the golden ticket didn’t hesitate to text, post on social networks, browse the web and yes, even stream live video during the game. And make no mistake about it, users expected that their messages, posts and videos would process without a hitch.
As anyone who has been to a sporting event, concert, rally or even a large graduation ceremony recently can attest, the absence of even a single bar or two of connectivity can be a frustrating experience. Networks quickly get bogged down when thousands of people with thousands of devices compete for the attention of the local communications infrastructure.
The most extreme example of this is the Super Bowl. In 2015 Verizon handled 7 terabytes of data at Super Bowl XLIX. In 2017, that number was up to 11 terabytes.
Stadiums use a hodgepodge of different methods to deal with the increased traffic. Today, most stadiums (including Oracle) have Wi-Fi — others work with communications companies on temporary solutions around large events.
Recently, we have seen stadiums take a more progressive and effective approach by installing antenna systems made up predominantly of a network of small cells — discreet nodes that can fit under seats or in the rafters. These antennas help build a more robust network inside the arena, specifically densifying the network by adding much needed capacity to deal with increased demand. That’s what U.S. Bank Stadium in Minneapolis did before the most recent Super Bowl. Verizon upped its small cell count to 1,200 from 900, according to the Twin Cities Pioneer Press, and AT&T and Sprint each deployed 800 small cells.
As demand for data grows, these tight-knit small cell networks must be expanded beyond stadiums and venues. Data traffic grew 238% over the last two years driven mostly by video and social networking. Further, traffic per user in North America is set to grow from 7 gigabytes today to 22GB by 2022.
The good news, small cells are already popping up in cities across America. Communications companies are investing heavily in small cell deployment understanding that our infrastructure is the bedrock of present and future connectivity. You see, not only do small cells add much needed capacity to power our current networks, but they are the key to ushering in the era of 5G – which will allow data to move 10 times faster than the current 4G network.
The bad news, largely due too unnecessary and dated regulatory red-tape, antennas are not being deployed quickly enough —a big reason the U.S. currently lags both China and South Korea is the race to 5G.
Just as the Warriors solidified themselves as the basketball dynasty of this generation with their clean sweep of the Cavaliers, America must establish itself as the technology dynasty of this generation by keeping us connected today and winning the race to 5G tomorrow — both of which start with infrastructure.
