1.2.2 Pre‐pandemic/Long‐term Requirements for Stadiums

Оглавление

For stadiums, a target of one million connections per square kilometer (also definable as 1 connection per m2 or one connection every 10 ft2) has been suggested by some researchers [2]. In the bleachers, the density could be high, even multiple individuals (say 2–3) every 10 ft2. Requirements include high‐capacity data and video access, IoT automation support, which also includes surveillance. The requirements are generally consistent with Table 1.2, with the coverage extending to parking lots. The services span more tightly defined time intervals (as contrasted to airports), possibly giving rise to a challenge in achieving certain goals for the Return on Investment on the infrastructure and the core‐network connectivity. The communication session may span the entire sporting event and a specified interval before and after the event.

A football field encompasses 57 600 ft2 (1.32 acres) but the bleachers may extend the area of coverage to two acres; the parking lots can cover several acres, but the traffic is sparser. Indoor sporting arenas could be smaller. The largest US stadium is the Michigan Stadium in Ann Arbor, Michigan, that seats about 115 000 spectators – about 10 stadiums in the United States can seat over 100 000 people. There are about 90 football stadiums that seat between 50 000 and 99 999 people, and there are about 50 stadiums that seat between 28 500 and 49 999 people. See Table 1.4. There are many other types of sporting venues (e.g. basketball courts, baseball fields, hockey arenas, soccer fields). Soccer field dimensions are somewhat wider than the regulation American football field, being 100–110 m long and 64–73 m wide.
