Today, we talk about the wired and wireless IoT Communication Technologies, the simple 13 common communication technologies in IoT.
We have compiled and summarized the commonly used wired and wireless communication methods of IoT for future reference.
Communication frequency band: license-free frequency band. Use Industrial Scientific Medical (ISM) frequency band, 915MHz (U.S.), 868MHz (Europe), 2. 4GHz (Global)
NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth, and can be directly deployed on a GSM network, UMTS network, or LTE network.
Communication frequency band: ISM frequency band including 433MHz, 868MHz, 915MHz, etc.
Communication distance: 2-5 km for towns, 15 km for suburbs
