Xiaobian today to organize the current under the four major LPWA technology, namely NB-IoT, LTE eMTC, LoRa and SigFox.
NB-IoT
The Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything. Constructed in a cellular network, the NB-IoT consumes only about 180 KHz bandwidth and can be directly deployed on a GSM network, a UMTS network or an LTE network to reduce the deployment cost and achieve a smooth upgrade.
LTE eMTC
The Internet of Things (IoT) access technology based on LTE evolution uses licensed spectrum like the NB-IoT, with enhanced coverage (15dB), high-speed mobile reliability and congestion control, and supports independent positioning. Compared with NB-IoT, eMTC has greater advantage in delay and throughput.
LoRa
LoRa is a low-power wide area network wireless communication technology developed by Semtech. The LoRa Alliance was established in March 2015 and currently has more than 290 members. Including operators, systems, software, chips, modules, cloud services, application vendors, constitute a complete ecosystem.
LoRa industry chain mature earlier than NB-IoT, for the rapid development of IoT business needs and technology window period, some operators choose to deploy LoRa as a supplement to the cellular Internet of things, such as Orange, SKT, KPN, Swisscom and so on.
Sigfox
Sigfox The French-based Sigfox builds a wireless network dedicated to IoT devices using Ultra Narrow Band (UNB) technology. Sigfox aims to become a global IoT operator by providing its customers with object networking, API interfaces and cloud computing Web services through self-built and cooperative network deployment with operators and other parties. Customers can pack up to about $ 1 per device per year Price to buy service. Sigfox is relatively closed, the ecosystem is relatively slow to build. Sigfox offers technology free to chipmakers and encourages chipmakers to integrate Sigfox technology in their products. TI, Intel, Atmel, SiliconLab and other companies are producing a variety of chips to support Sigfox technology. Sigfox network has covered France, Spain throughout the country, the United States, the Netherlands and the United Kingdom in some cities.
