In a stadium deployment, which WLAN design approach is most recommended?

Using few APs at maximum power in a high-density environment causes severe co-channel interference and limits total capacity - the 2.4 GHz band also has only 3 non-overlapping channels, making it unsuitable as the primary band for stadium deployments.

In a stadium, thousands of clients are concentrated in a small area, making capacity per AP the critical design constraint. Sectorized directional antennas focus RF energy toward specific seating sections, reduce the coverage overlap between APs, limit co-channel interference, and allow more APs to reuse the same channels. This high-density design pattern places APs close to users (under-seat or in handrails) rather than relying on distant high-power APs.

Ceiling-mounted omnidirectional antennas in a stadium bowl would create massive RF overlap, high co-channel interference, and poor signal-to-noise ratios due to the large number of APs all radiating in all directions simultaneously.

Placing APs only on one side of the stadium results in the opposite side having poor or no coverage, leaving large areas of the venue unserved and failing basic coverage requirements.
