- 초록
- In the building outside, the requirement about the sensor network applications increases, but it is difficult to build the sensor network in the building outside the frequency problem. The frequency band issued for the IEEE802.15.4 processed with the physical layer of the sensor network and standard of the MAC layer is 2.4GHz and 868 / 915MHz. As to the frequency, which we can use within Korea, 2.4GHz is unique. 2.4GHz node is difficult to operate in the building outside. In Korea, the frequency band that we can use as the narrow band is 424 and 447MHz band. Therefore, the sensor node of 424 or 447MHz band can operate in Korea was needed.
