Spectrum clash builds around bionic implants

The battle over scarce radio spectrum that has embroiled the mobile broadband world even extends to a little-known type of wireless network that promises to reconnect the human nervous system with paralysed limbs.

At its monthly meeting next week, the US Federal Communications Commission will consider whether four sets of frequencies between 413MHz and 457MHz can be used by networks of sensors implanted in patients who suffer from various forms of paralysis. One intended purpose of these MMNS (medical micropower network systems) is to transmit movement commands from a sensor on a patient’s spinal cord, through a wearable MCU (master control unit), to implants that electrically stimulate nerves. The same wireless technology might be used in devices to restore sight or hearing — via redwolf.newsvine.com
