Network engineering strategies for guaranteeing unbroken physiological telemetry across busy hospital wards.
Hospital corridors are saturated with RF interference from smartphones, medical cart tablets, mobile X-ray units, and metal equipment racks, creating multipath fading and localized signal shadows.
Clinical telemetry transmitters must tag packets with DSCP Expedited Forwarding (EF) and utilize WMM Voice (AC_VO) queues to ensure APs transmit life-critical telemetry ahead of routine web browsing or video calls.
As an ambulatory patient walks through hospital hallways, their telemetry transmitter must execute sub-50ms handoffs between access points using IEEE 802.11r fast transition keys, preventing heartbeat dropouts.
