Centralized RAN or C-RAN is an architectural shift in RAN (Radio Access Network) design, where the bulk of baseband processing is centralized and aggregated for a large number of distributed radio ...

Grow capacity with Liquid Radio – Centralized RAN •
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
Sizes 10 000 to 250 000 people > 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
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
Tailgate party before the event and during it Video feed from the game Arrival to and departure from the game Handovers to/from macro layer Optimized together with macro parameters
Arrival to and departure from the game > Handovers to/from parking lot to LTE for stadium network > 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 the network performance while crowds are on the move
