- 초록
- The 3GPP Release-13 has introduced a Narrowband Internet of Things (NB-IOT) which is capable of Low Power Wide Area (LPWA) IoT service. NB-IoT can interfere with LTE cellular because the NB-IoT uses the license band differently from the LPWA IoT (Sig-fox, LoRa, and so on) using the unlicensed band. In this paper, it is shown that NB-IoT can cause interference even though subcarrier frequency 15 kHz like LTE is used, and the degree of interference is shown through testing. The test results show how to suppress NB-IoT interference for LTE and LTE resource allocation.
