BAN

IEEE 802.15.6 defines the high-reliability standard for short-range wireless communication inside or around the human body.

Body Area Network (BAN) technology utilizes low-power nodes (sensors and actuators) to facilitate medical monitoring and consumer electronics. Operating primarily in the 2.4 GHz ISM band or via Medical Body Area Network (MBAN) spectrum (2360-2400 MHz), it supports data rates up to 10 Mbps. Systems like the Medtronic Micra pacemaker or Dexcom G6 glucose monitors leverage these protocols to transmit physiological data to external hubs with minimal latency. The standard prioritizes extreme energy efficiency (extending battery life to years) and stringent security to protect sensitive biometric packets.
