With NB-IoT technology in the wake of the wind in the field of IoT and the popularity and slow sales of wearable smartwatches and wristbands, it is often seen that NB-IoT technology addresses the pain points of smart wearable devices, Meet each other late.
But is that really the case? Do we really need NB-IoT for wearable devices or does NB-IoT really be a big fix for smart wearable devices? That may not be the case.
According to our review, such views are mainly that NB-IoT low power consumption, low cost, strong coverage, just can solve the smart wearable device using time is short, high prices, strong dependence on mobile phones and other pain points.
First of all, the wrist smart wearable device in the market can be divided into three categories: bracelet (without long-distance connection function), call watch (call available), smart watch (with LTE call and connection function, and loadable application)
Power consumption
Said NB-IoT low power consumption, it is relative to the existing LTE or 3G, 2G devices, so for the original hand ring without 2G / 3G / 4G connectivity, an NB-IoT communication module, Will only increase power consumption, reduce the use of time. Therefore, to extend the use of time is obviously not aimed at the wristbands such devices, only possible compared to call watches and smart watches.
However, NB-IoT does not support voice calls at all, so calls are apparently not available. Even at the expense of call features, used in LTE smart watches, because of the low power consumption of NB-IoT is mainly based on a long time "strike" to the outside world do not ask for a change, which means that others send you a WeChat message For example), you may have to wait for thirty-five minutes to receive, such a bad experience who is willing to use?
Cost
As with power consumption, adding an NB-IoT communication module to a wristband that does not have 2G / 3G / 4G connectivity adds cost and no cost reduction. Because it does not support voice, call the watch certainly can not be used, unless you engage in a NB-IoT and GSM dual-mode, this is obviously only higher than the single GSM costs will be higher. Finally, look at LTE smart watches, compared to the existing LTE communication module, NB-IoT module costs have indeed dropped significantly, but in addition to the aforementioned ultra-high latency, NB-IoT very low rate (<250Kbps), does not support voice calls , These will determine the NB-IoT can not replace the LTE module on existing smart watches.
3 separate from the phone to use
The current wearable devices do depend heavily on mobile phones. In particular, wristbands require communication with mobile phones and management APPs via Bluetooth. The NB-IoT can do the same with existing 4G / 3G / 2G phones and smartwatches for the long-distance communication watch and smartwatch itself. (Speed, real-time, etc.). Therefore, the only hope is to add the NB-IoT communication module to the bracelet product. However, the application of the wristband product can not only upload the motion data and so on to the cloud server independently but also independently receive the SMS, Not to mention adding SIM cards, antennas, etc., and the resulting cost, size, and design impact.
In summary, we believe that NB-IoT can solve the smart wearable device using a short time, high prices, the phone is dependent on the strong point of pain is completely true.
That if the user is willing to pay (fare increase), NB-IoT technology used in smart wearable devices, there will be other surprises? And voice-enabled eMTC technology, applied to the smart wearable device can solve the pain points or bring any surprise Soon, let's try to answer these questions.
First, the unlocking method is to use a two-dimensional code to open, whether it supports other unlocking methods, such as mechanical keys or cards or fingerprints, these can be negotiated with us.
Second, convenience. It`s easy to lose keys and proximity cards. It`s troublesome to go out for a run, but mobile phones have become as important as our organs. When we use our mobile phones to get the QR code to open the door, we won`t lose them. Open it directly and swipe the door very convenient. If you share the key with your friends, you can set the number of unlocking times, the time limit for unlocking, etc. Anyway, who can open it and how long it will last is all up to you. No more silly going downstairs to pick up guests.
The third is to facilitate management. Its software has functions such as key sharing, management, access control record viewing, and role unlocking authority. It is suitable for places such as hotel apartments that require strict management of a large number of entrance guards and rooms.
