In today's fiery hardware, I believe there are many people to catch up with fashion trends, wearable products can not get rid of the dependence on mobile phones, high frequency mobile phone charging also affects the long-term wear enthusiasm, coupled with inaccurate measurement indicators can not be continuous Monitoring and other factors, the user's viscosity is gradually reduced. Under the theme of "NB-IoT-Based Smart Wearable Products" at the "2nd China NB-IoT Industry Alliance Summit Forum" held in Shenzhen Convention & Exhibition Center, smart-wearable products based on NB-IoT technology do not have Rely on smart phones, battery life, do not lose the characteristics of data and solve the current drawbacks of relying on WiFi, Bluetooth communication means. Today's smart wearable and tracker are based on 2G and 3G, power consumption is a big problem. These networks and chips are all customized products for mobile phones. The applications of mobile phones have tended to be more high-speed and high-bandwidth LTE, resulting in technical bottlenecks such as large power consumption and large chip area for intelligent wearable products. With the gradual withdrawal of 3G and 2G networks, the path of smart wearable independent terminal development is even more confused. Low power consumption, small size, low speed and low cost have become the requirements of smart wearable communication technologies. B-IoT technology has five major advantages: 1, large capacity Compared with 2G / 3G / 4G, NB-IoT has an uplink capacity increase of 50 to 100 times, which means that the same base station can use this technology to increase access time by 50 to 100 times than existing wireless technologies. 2, wide coverage NB-IoT than the original LTE connection to enhance the gain of 20dB, equivalent to a 100-fold increase in transmit power, so more penetrating, covering the underground garage and so on. 3, low power consumption The energy consumption of communication devices is closely related to the amount of data or rate, and the NB-IoT focuses on small data rates and small rate applications. It also introduces ultra-long DRX (Discontinuous Reception) and PSM power saving technologies, which greatly reduce power consumption . The power consumption of NB-IoT is only 1/10 of GSM. 4, low cost Due to the low rate and low bandwidth, the required RF, PA and other requirements will be lower, and the cost of the chip will be significantly reduced. Meanwhile, because IoT can be directly deployed in GSM, UMTS, LTE networks, existing base station reuse can also reduce the deployment cost. 5, high stability NB-IoT uses a separate band of 180KHz, which does not occupy the voice and data bandwidth of the existing network and can better ensure that the future IoT and traditional services can be simultaneously and stably performed. Huawei colleagues briefed us on the NB-IoT situation, we have no hesitation to follow and try, we think this is the smart wearable device technology (low power consumption + independent terminal). NB-IoT technology allows us to see the hope: to make similar millet bracelets or Apple Watch products and mobile phones can be used independently, independent of the phone, it may last for more than 30 days. Deep coverage technology can make wearing the product antenna easier, in the wearable product small antenna can also get good results. In addition to wear on the person, positioning and tracking and other needs of the application is also very clear. NB-IoT intelligent wear and tracker Tracker pioneer. Consumer electronics and medical products that deal with people, pets, object tracking, and emotions can be added to these applications that allow users to spend and increase APU values. The replacement of these products further drives the sales volume of NB-IoT products, which eventually leads to the rapid cost reduction of NB-IoT and makes the development of NB-IoT products easier.
