The latest research report “authorized low-power cellular connectivity of the Internet of things by vertical market” released by strategy analytics predicts that although the start-up is slow outside China, the number of authorized low-power lpwa connections will increase to nearly 900 million by 2025, which will greatly exceed the unlicensed lpwa connections in the same period.

Many IOT applications run efficiently without high bandwidth or ultra-low latency. Therefore, 2G technology is still effective for many Internet of things applications. As the world moves to 5g, low-power solutions are also evolving to meet the needs of the Internet of things. 4G LTE has been able to support cat 0 and cat 1. However, in the 3GPP release 13 standard defined in 2016 / 2017, specific versions of LTE (i.e. LTE m and Nb IOT) are defined, so that Internet of things applications can be used safely and with low power.

Strategy analytics provides OEM technology to make IOT applications safe and low-power

Andrew brown, executive director of enterprise and IOT research at strategy analytics, said: “there are more than 92 Nb iots and more than 36 LTE m networks, and this number has been growing, and there are a number of service providers and module OEMs supporting these two technologies. With the roaming problem around NB IOT effectively solved, the future seems optimistic. “

“Driven by China’s huge infrastructure projects, as well as NB IOT’s strong indoor coverage, extremely low cost and long battery life, Nb IOT has become the leading technology, and LTE m will continue to play an important role in applications and voice support with significant downlink requirements, as well as FOTA (air firmware) support. With the phasing out of 2G and 3G networks, authorized low-power technologies running on 4G and 5g networks will be crucial in IOT deployment. NB IOT and cat m will be covered by 5g and will be the preferred technology for mmtc (mass machine communication) in 5g. 5g NR (new radio) is designed to support multiple deployment modes. Starting from 5g NR, 3GPP may make it possible for LTE m and Nb IOT transmission to be placed directly in 5g NR band. This only requires ran support on the core network. With cellular networks, we believe that in the long run, these technology opportunities are extremely feasible. “
