Why each option
In healthcare environments, RF interference is the paramount design concern because it can disrupt life-critical medical devices and degrade patient monitoring systems.
DFS channels help avoid radar interference but do not address the broader RF environment that affects sensitive medical equipment.
Medical devices such as infusion pumps, telemetry monitors, and wireless ECG systems are highly sensitive to RF interference in the 2.4 GHz and 5 GHz bands. A wireless design that minimizes co-channel and adjacent-channel interference protects both the Wi-Fi network and the medical equipment operating alongside it, which is a patient-safety requirement.
160 MHz channels consume more spectrum and increase the risk of interference - the opposite of what a high-device-density healthcare environment requires.
Maximizing AP transmit power increases signal overlap and co-channel interference, worsening the RF environment for nearby medical devices.
