What is needed in stadiums Case: Superbowl

2012 Lucas Oil Stadium > Indianapolis 68,658 fans in the stadium

> 215 GBytes of wireless data through mobile systems

> Uploads accounted for 125 GBytes against 90 GBytes in

downlink: 58/42 % UL/DL ratio

Devices are meanwhile getting better and picture

and video files larger

2013 Mercedes-Benz Superdome New Orleans, 71,024 fans in the stadium

> 388 GBytes of AT&T 3G/4G data

> 80% more data year-on-year

60% 80%

NSN Centralized RAN C-RAN turns harmful interference into useful gain

C-RAN Co-operative clusters

> Multiple Aperture Antenna Selection

> UpLink Co-operative MultiPoint

C-RAN maximizes capacity, throughput and

makes super-cell intelligence to mitigate

> The highest traffic and worst interference problem > social media uploads, video feeds

> game statistics and home team portal

> other games and whole league information services

> Operator game portal

> Goals generate in-game peaks

> Prevent handovers to/from macro

> Idle mode while no events > power down most cells

> energy saving

Stadium bowl Sizes 10 000 to 250 000 people

Stadium concession areas Typically below or behind and isolated from the bowl

> Peaks during pre-game and breaks

> Food / beverage / fan merchandise sales

and restrooms

> Lower capacity and density than the bowl but still

significant capacity needed

> Prevent handovers to/from macro

Stadium parking lot and tailgate party

> Tailgate party before the event and during it

> Video feed from the game

> Different parameter sets: no game / before

game / during game / after game

> Macro cells potentially pointing away from the

Stadium; installed in the stadium structure

> Immediate vicinity macro cells connected to

NSN LTE for stadium to optimize and automate
