The reason for reduced 802.11a connectivity in an X-ray room is due to the significant non-Wi-Fi interference created by X-rays on the 802.11a band.
X-rays generate electromagnetic radiation that can cause interference with radio signals, including Wi-Fi. The 802.11a standard uses the 5 GHz frequency band, which is also used by medical equipment, including X-ray machines.
X-rays have a higher frequency than Wi-Fi signals, and their energy can cause interference with the Wi-Fi signal, resulting in reduced signal strength and quality. This interference can be particularly problematic in areas with sensitive equipment or where the signal strength is already low.
In addition, X-rays within these rooms can cause multipath issues. Multipath occurs when radio signals bounce off walls, ceilings, and other objects, causing multiple signals to arrive at the receiver at different times. This can result in signal interference and degradation, reducing the quality of the Wi-Fi signal.
Lastly, X-ray rooms exhibit increased signal attenuation. Signal attenuation occurs when the signal weakens as it travels through objects such as walls and floors. In X-ray rooms, the thick walls and lead-lined doors that are designed to contain the X-ray radiation can also attenuate the Wi-Fi signal, reducing the coverage area of the access points.
Therefore, to ensure reliable Wi-Fi connectivity in an X-ray room, it is essential to carefully design and deploy the wireless network. This may involve using alternative frequency bands, such as 2.4 GHz or 5 GHz UNII-1 channels, that are less likely to experience interference from X-rays or implementing additional access points to compensate for signal attenuation.
