    Abstract: 隨著物聯網技術的快速發展以及智能裝置大量的被使用,物與物互相彼此的連接,日後邁向萬物互聯是必然的結果,而NB-IOT在這當中扮演相當重要一環,它是技術更迭和市場需求的綜合產物,在未來的市場一致的被看好。
    ;With the rapid development of Internet of Things and the large number of intelligent devices are used, devices and devices connected with each other. In the future, Each devices will connected is the inevitable result. NB-IOT play a very important part of this. It is by technology change and market demand synthesis product and the market consider it have a bright future.
    NB-IOT is proposed by 3GPP in Rel-13 and has many advantages. Such as wide coverage, low cost, low power consumption and can use authorized spectrum. It has less interference, and support in-band, guard-band, and stand-alone. Because NB-IOT hope to achieve one of the objectives is a large number of devices can be connected. So how to effectively allocate these devices into different frequency bands is to research in this paper. In this paper proposed AHP band selection algorithm to select a more appropriate frequency band to the device. The algorithm in the choice of frequency band will not only consider the device for each band of channel quality measurement parameters, but also choose the situation in band. The final simulation results will show a better throughput tan the other methods proposed.
