APPENDIX II

Wireless Technology

RF wireless technology is used in the communication between an
OPTIMIZER Lite Implantable Pulse Generator (IPG) and the
Vesta Charger. It occurs through an encrypted channel over an
RF link that complies with the requirements of the Medical Implant
Communication System (MICS) (range specified to 2 m, 402–405
MHz) of the MedRadio Band.
RF wireless technology is also used to transcutaneously transmit
energy from the Vesta Charger to recharge the OPTIMIZER Lite
IPG at the 13.56 MHz ISM frequency. The transmission range is
specified at a maximum of 1.5 inches between the Charger's coil
and the IPG's receiving coil. Control over the recharge process,
as well as the communications of alert messages from the IPG to
the Charger take place over the encrypted MICS channel.
