8. doc.: IEEE 802.15-13-0433-00-004q Submission ETRI July 2013 Medical Frequency Band of 401-406 MHz The medical device is a representative application requiring the ULP technology. The MICS band and the adjacent frequencies are required as the ULP band. –MICS band : 402-405 MHz –MedRadio/MEDS band : 401-402 MHz, 405-406 MHz –The IEEE 802.15.6 has already completed the channel model of MICS.

9. doc.: IEEE 802.15-13-0433-00-004q Submission ETRI July 2013 Summary The ULP technology is useful for applications including the implantable medical device. –The implantable medical device has essentially the characteristic of ultra low power consumption. The ULP should support the data rate of less than 10 kbps. –Most implantable medical devices do not need the high data rate of 1 Mbps. The additional frequency bands of the ULP are required. –MICS band (401-406 MHz) –MedRadio/MEDS band (401-402 MHz, 405-406 MHz) Slide 9
