China will have a billion machine-to-machine (M2M) connections in use by 2020, with the majority coming from the developing Low Power, Wide Area (LPWA) market, according to GSMA Intelligence and the China Academy of Information and Communications Technology (CAICT).
Cost and low battery consumption are big drivers of thinking about network characteristics for support of Internet of Things apps and devices, particularly industry applications intended to work in rural areas, or in any setting where labor cost to replace batteries affects the business model.
And even if an ideal network might support every conceivable media app and application setting equally well, that is not the case, at present. For such reasons, special-purpose IoT networks such as the several low-power IoT alternatives, based on use of unlicensed spectrum, have been developed.
The report says China is now the world’s largest M2M market with approximately 100 million mobile M2M connections, increasing to 350 million by 2020.
However, an additional 730 million connections will be enabled by LPWA technology, taking the total figure to just over one billion. By 2025, it is expected that half of the world’s 28 billion connected devices will be suitable for connection by LPWA networks.
Also, the installed base of wireless Internet of Things (IoT) devices in industrial automation reached 14.3 million in 2015, according to Berg Insight.
The number of wireless IoT devices in automation networks will grow at a compound annual growth rate of 27.7 percent to reach 62.0 million by 2021, powered by a number of wireless networks, including Wi-Fi and Bluetooth, the most widespread technologies in factory automation.
Mobile networks more typically are used for remote monitoring and backhaul communication between plants, Berg Insight says. It is highly possible that a great percentage--perhaps a preponderant majority--of IoT connections actually will use Wi-Fi or Bluetooth connections, not LoRa or mobile connections, through 2021.
