A medical device comprises a medical imaging, diagnostic, or therapeutic component (10), and an access point (30) operating as a hub for a wireless local area network (WLAN) complying with a wireless communication protocol having a defined set of WLAN channels. The access point includes a radio (32), an electronic processor (34), and a non-transitory storage medium (36) storing a list of one or more critical medical WLANs (40) and instructions executable by the electronic processor. Scan instructions (42) operate the radio to measure traffic on the WLAN channels generated by critical medical WLANs listed on the list (40). Channel selection instructions (44) select a channel based on at least the measured traffic on the WLAN channels generated by critical medical WLANs on the list (40). WLAN operating instructions (46) operate the access point as a hub for a medical device WLAN carrying traffic on the selected WLAN channel.
