Low-power wide area networks (LPWANs) will be key drivers for IoT applications. According to the GSMA Industry Paper report, there will be more than 2 billion LPWAN devices connected to the Internet in 2019, which will not only meet the commercial development of the Internet of Things, but also have potential business opportunities. To this end, system vendors and telecom operators are actively engaged in market layout, in addition to grabbing market opportunities, and further accelerate the commercialization of LPWAN.
Zhang Qi, Industry Consultant and Director of MIC Smart Technology and Netcom Research Center, said that the backhaul network will play a key role in LPWAN information transmission. According to the return of network ownership, three service supply models will be distinguished in the future. Mode 1 is for LPWAN operators to have backhaul networks (such as Sigfox in France); Mode 2 is for LPWAN operators to lease operator telecommunications networks (such as Fuhong + Asia Pacific); Mode 3 is for carriers to operate LPWAN and backhaul networks (such as SKT) , Vodafone).
In addition, the backhaul demand of LPWAN information will also drive cable TV, satellite and energy operators, except telecom operators, to use their existing network facilities to combine LPWAN cut-in and enhanced IoT services. For example, Comcast, the largest cable operator in the United States, will announce LoRa commercial services in a year; European media group AlTIce also said it will cooperate with Sigfox to provide backhaul services; Tokyo Electric uses Wi-SUN to provide smart meter services in conjunction with its own network. The above players are expected to become a new force in the LPWAN IoT service.
On the other hand, optimistic about LPWAN development opportunities, STMicroelectronics (ST) also launched a new generation of IoT RF transceiver chip - S2-LP. The product operates in the sub-1GHz band and does not require a license. Its advantages include efficient use of the radio frequency band, transmission of data via low-power signals, reliable communication connections, long transmission distances, and low power consumption for smart networking devices. Can work continuously for up to 10 years without the need to replace the battery. At the same time, the transceiver supports the Sigfox communication protocol, with pre-certified development tools, direct link to the Sigfox network, evaluation of applications and development prototypes, providing a reliable, cost-effective, cost-effective solution for billions of sensors and smart objects. Communication solution.
In summary, traditional cellular applications for IoT applications that require wide-area coverage, relatively low bandwidth, excellent battery life, low hardware and operating costs, and high connection density. The network cannot combine the above technical conditions. As a result, the rise of LPWAN has prompted semiconductor companies, system manufacturers and telecom operators to invest in the development of this technology, hoping to support hundreds of thousands of devices or similar objects that link to base stations through LPWAN without costly. Achieve many applications of the Internet of Things.
