Refer to the exhibit. A new wireless deployment with high AP density is experiencing high latency and connectivity issues on the 24 GHz band, despite an initial site survey done by a certified…

Increasing the fragmentation threshold allows larger packets, but this might not resolve issues in a congested environment; smaller packets due to a lower threshold can sometimes be more resilient to interference, so increasing it might worsen issues.

Reducing the beacon period increases the frequency of beacons, which consumes more airtime and could increase RF interference and overhead, worsening the problem rather than reducing it.

Disabling lower data rates, such as 1 Mbps and 2 Mbps, forces wireless clients to associate and communicate at higher, more efficient data rates. In a high-density environment, lower data rates consume significantly more airtime for the same amount of data, leading to increased contention, latency, and overall network congestion, especially on the crowded 2.4 GHz band.

Disabling the short preamble and forcing long preamble would typically increase overhead and consume more airtime, which is counterproductive in a high-density environment experiencing latency and connectivity issues. Short preambles are generally preferred for efficiency.

Disabling 802.11g support would prevent 802.11g clients from connecting and force 802.11b-only operation, which uses even lower data rates and is highly inefficient, exacerbating the issues on the 2.4 GHz band.
