Analysis of Qualcomm LPWAN Multimode Tactics from the Application of Motorcycle

Since last year, a wave of low-power wide area network (LPWAN) has swept the entire communications and even the Internet of Things industry. People have placed great hopes on LPWAN technology. Many people even think that LPWAN technology is the basic guarantee for the development of the Internet of Things industry.

However, so far, LPWAN technology only has some market promotion of non-licensed channel technologies such as LoRa, while the cellular Internet of things technologies such as NB-IOT and eMTC are still in the process of establishing networks. Although the three major domestic carriers are speeding up the network construction , But because the application is still at an early stage and the specific application scenario needs to be tested by the market, it is still too early to talk about billions or even tens of billions of explosions. How to deal with this early market, companies need to explore.

Qualcomm's multi-mode strategy

Compared to Huawei has been pushing NB-IOT, another big wireless communications giant Qualcomm for LPWAN technology choice is the main push NB-IOT / eMTA / GSM multimode products, and has now begun to promote the application.

On May 23, 2017, Qualcomm announced that it plans to collaborate with China Mobile Research Institute and the leading motorcycle sharing company in China to launch China's first eMTC / NB-IoT / GSM (LTE Cat M1 / ​​NB1 and E-GPRS Multimode field test. The outfield test plan takes full advantage of China Mobile's 2G / 4G multimode network to apply Qualcomm's MDM9206 global multimode LTEIoT modem for Internet of Things applications to its smart car locks. With the LTE connectivity and integrated Global Navigation Satellite System (GNSS) positioning capabilities of the MDM9206 LTE IoT modem, Motorcycle users can more accurately identify available bicycles, speed up unlocking of smart locks, and continuously monitor and manage their cycling status in real time .

Qualcomm's multi-mode tactic is a wise choice for now.

For application enterprises, IoT scenarios are complex, a single network can not guarantee demand

IoT scenarios are complex, and for many devices and applications, using a single communication technology is not reliable. As we use the phone, you need to use 2G / 3G / 4G network to meet the conversation, voice, video and other diverse functions, and can be connected to the network in different locations and environments (extreme environment Next, say), so as to meet our needs. The same is true for many IoT scenarios.

At the conference, vice president of technology Li-Xing Xing of Qualcomm Technologies, Inc said that at present the hottest NB-IOT and eMTC technologies actually have different applicable scenarios. Compared with NB-IoT, eMTC has higher reliability and better data volume support. eMTC is better suited for use cases that are relatively sensitive to latency, such as building security, wearables, smart tracking, asset tracking, and critical infrastructure.

For NB-IoT, firstly, it is less sensitive to delay. Second, it requires high cost and data traffic is very low. Some use cases are reported once a month, such as water usage or power usage , This time NB-IoT can be responsible for this use of the scene.

In mobile IoT, eMTC and NB-IoT each have different advantages and disadvantages. Therefore, there may be no way to satisfy all possible usage scenarios with a single technology.

Multimode products in the early days of the Internet of Things is easy to eat more markets, reducing the risk of early investment

In addition to the application-oriented, we know that the realization of cellular Internet of things technology needs to rely on the promotion of operators, and for NB-IOT or eMTC network construction, different operators have made different choices, the three major domestic carriers and Vodafone and other communications giants will give priority to the development of NB-IOT, while Verizon, AT & T and other telecommunications companies will give priority to promoting eMTC networking. Coupled with the major operators of the current operation and maintenance of 2G users can not be ignored, so the introduction of multimode products for the early market for the Internet of Things is undoubtedly a wise choice.

At the press conference, the cycling demonstration demonstrated that the integrated NB-IoT / eMTC / GPRS multi-mode technology test bike is the best demonstration of the current LPWAN application market as it is a multi-million-dollar IoT products companies, cycling in all over the world, therefore, to operate a good bike in different markets need to be able to integrate a different communication technology products, in order to take all the market.

Of course, multimode products should only be a transitional product in the early days of the Internet of Things. After integrated multimode, the added hardware cost and post-operation cost are unaffordable to many application enterprises. I believe that after the market for Internet of Things , Communication hardware products are also toward the simplification and low-cost direction.
