Since last year, a low-power wide-area network (LPWAN) has swept the entire communications and even the Internet of Things industry. People have high hopes for LPWAN technology. Many people even think that the maturity of LPWAN technology is the basic guarantee for the development of the Internet of Things industry.
However, so far, LPWAN technology only has some marketing channels such as LoRa and other unlicensed channel technologies, and cellular IoT communication technologies such as NB-IoT and eMTC are still in the network construction stage, although the three major operators in China are accelerating network construction. However, because the application is still in an early stage, the specific application scenarios still need to be tested by the market. It is still too early to talk about billions or even billions of outbreaks. How to deal with the current early market requires companies to explore.
Qualcomm's multi-modal strategy
Compared with Huawei has been pushing NB-IOT, another major wireless communications giant Qualcomm's choice of LPWAN technology is the main push NB-IoT / eMTA / GSM multi-mode products, and has begun to promote applications.
On May 23, 2017, Qualcomm announced that it plans to cooperate with China Mobile Research Institute and China's smart shared bicycle leader Mobike to launch China's first eMTC/NB-IoT/GSM (LTE Cat M1/NB1 and E-GPRS). ) Multimode field test. The field test plan makes full use of China Mobile's 2G/4G multi-mode network to apply Qualcomm's MDM9206 global multi-mode LTIOT modem for IoT applications to the smart car lock of the Mobility bicycle. With the LTE connection and integrated Global Navigation Satellite System (GNSS) positioning function of the MDM9206 LTE IoT modem, Mobike users can more accurately identify available bicycles, speed up the unlocking of smart locks, and continuously monitor and manage the status of bicycles. .
Qualcomm's multi-mode tactics are now a smart choice.
For application companies, the IoT application scenario is complex, and a single network cannot guarantee the demand.
The application scenario of the Internet of Things is very complicated, and for many devices and applications, the use of a single communication technology is not reliable. For the mobile phone we use, we need to use 2G/3G/4G network in combination to meet the various functions of call, voice, video, etc., and to be able to connect to the network in different places and environments (extreme environment) Let's talk about it), in order to meet our needs. The same is true for many IoT applications.
At the press conference, Li Weixing, vice president of technology at Qualcomm Technologies, Inc., said that the hottest NB-IOT and eMTC technologies have different application scenarios. Compared with NB-IoT, eMTC has better reliability and data volume. support. eMTC is more suitable for use cases where latency is relatively sensitive, such as building security, wearables, smart tracking, asset tracking, and critical infrastructure.
For NB-IoT, first of all, it is relatively less sensitive to delay; second, it has high cost requirements, and data traffic is very low. Some use cases are reported once a month, such as water usage or power usage. At this time, NB-IoT can be responsible for this usage scenario.
In the mobile Internet of Things, eMTC and NB-IoT have different advantages and disadvantages, so there is no way to satisfy all possible usage scenarios with a single technology.
Multi-mode products can easily eat more markets in the early days of the Internet of Things, reducing the risk of up-front investment
In addition to the application orientation mentioned above, we know that the implementation of cellular IoT technology needs to rely on the promotion of operators. For NB-IOT or eMTC network construction, different operators have made different choices, and the three major operators in China. Communication giants such as Vodafone will give priority to the development of NB-IOT, while communication companies such as Verizon and AT&T will give priority to eMTC networking. In addition, the major operators have no problem to ignore the operation and maintenance of current 2G users. Therefore, the introduction of multi-mode products is undoubtedly a wise choice for the early days of the Internet of Things.
At the press conference, the integrated NB-IoT/eMTC/GPRS multi-mode technology test bike demonstrated by Mobike Bicycle is the best display for the current LPWAN application market, because Moby is operating as a multi-million-level operation. Internet of Things products companies, bicycles are distributed all over the world, therefore, to operate a bicycle in different markets requires a communication product that can integrate different technologies in order to eat the market.
Of course, multi-mode products should be just a transitional product in the early days of the Internet of Things. After all, multi-mode integration, the increased hardware costs and later operating costs are unwilling to be accepted by many application companies. I believe that after the Internet of Things market is up, Communication hardware products are also developing towards simplicity and low cost.
