1. Needless to say, now in the Internet of Things industry, NB-IOT is definitely the communication technology standing on the cusp. With the NB-IOT standard determined in 2016, everyone is also predicting that this year will be the first year of NB-IOT technology commercialization. As far as the current market is concerned, large companies related to IoT applications are concerned about NB- IOT application technology.

2. It is worth noting that the NB-IOT is implemented by the operator's unified deployment and coverage of the network base station. In the future, the domestic NB-IOT network will be operated by the three major operators, and now the fastest network is telecommunications. Operated by the operator, the problem of network charging is followed. The application of NB-IOT technology also requires a SIM card, and the incidental cost is a problem.

Is it a consumer? Still a manufacturer? Or an operator?

This problem is not a big problem, but it should be combined with market demand pain points and positioning pre-consideration and input-related business communication.

3. Someone asked: "Is this nbiot radiation low, or is the sim card communication radiation low?".

NB-IOT is a SIM card. . . .

For the amount of radiation, the amount of radiation from all currently applied wireless communication technologies is negligible for humans. This problem is a false proposition.

For NB-IOT, everyone is more concerned about power consumption, because power consumption directly determines the battery life and the user's charging frequency. The power consumption of NB-IOT is one order of magnitude lower than that of the previous 2G GPRS module (GPRS sleep current ≤ 50uA, NB-IOT module power consumption ≤ 5uA), which is indeed much lower. But it is still much higher than BLE.

At present, smart wearable products have more BLE technologies, so in the case of the same battery capacity, the number of products used by NB-IOT is definitely less than that of BLE.

4, NB-IOT itself communication rate is relatively low, so it is not recommended for products that require large data volume transmission.

5. The problem directly caused by power consumption and rate is that NB-IOT technology is not recommended for applications with high real-time data uploading.

6, the future cost of NB-IOT module, of course, if the market yields, the price of NB-IOT chips and modules will drop significantly. And there are currently subsidies from operators.

7, say some advantages of the application of NB-IOT: can solve the problem that BLE technology can not be separated from the mobile terminal. NB-IOT is an independent upload terminal. Smart wearable products can be used independently from mobile phones, and there is no dependence on mobile phones. And it consumes less power than a traditional 2G network.

8. The current NB-IOT module cannot be located, and even if there is a base station positioning later.

9, the current release of the protocol version, NB-IOT module intelligent active timing report, temporarily can not meet the downward copy.

10. Currently, the size of a module is larger than that of a NB-IOT on the market.

11, expensive

In summary: If the subject is now evaluating the application of smart bracelets and watches: the frequency requirements for uploading, real-time performance is not so high, and some application scenarios of customers can get rid of the mobile phone, and if the user is on the same mobile phone with the smart device Bluetooth If there are some obstacles in WIFI pairing (such as the elderly), then NB-IOT technology may be the best solution for you.

Another: There are many smart wearable applications based on NB-IOT technology on the market. However, they are also forward-looking products. In the future, mass production and applications still need full network coverage.

However, the core of smart wearable products is still the use of scenes and user demand pain points. NB-IOT these LPWAN technologies are only means, and creativity is the core.
