Mobile Internet of Things technical characteristics, applicability and development path

Commonly used Internet of Things technology includes: 2G, 3G, 4G, satellite communications, LoRa, SigFox, eMTC, NB-IoT and other technologies.

Internet of Things application scenarios

LPWA technology in the field of low power consumption and wide coverage of IoT is most favored by operators to meet the market demand of operators in open areas and at low cost and broad coverage of IoT. In the market, LPWA technology based on unlicensed spectrum, mainly LoRa, SigFox dominated.

Internet of Things technology development track

Unauthorized spectrum to seize the initiative, access to a range of uses

LoRa, SigFox technologies are all unlicensed spectrum, making connections on the public spectrum. Public spectrum is like a public road. Everyone can use it without authorization. Unlike the 2G / 3G / 4G network of telecom operators, it belongs to the exclusive channel and needs to be licensed for use.

LoRa started to be deployed in some countries in 2013. LoRa Union was subsequently established, making the industrial chain has been greatly developed, the international well-known enterprises and operators to join, page enhanced the alliance's strength and influence.

SigFox commercial time later than LoRa some, but in the international community has also been a certain amount of applications, the operators are Orange France, South Korea SK Telecom and so on.

Licensed spectrum come from behind, and gradually lead the market

LoRa and SigFox got the operator's choice because they appeared earlier and were more mature than the LPWA technology based on the licensed spectrum. They were also available on a large scale and could meet the needs of some users at that time.

As technology advances and evolves, by 2016, two technologies, NB-IoT and eMTC, have emerged, and both have adopted a unified 3GPP standard to extend the Internet of Things. This technology has industry-standard attributes, is open, and the technology used is a gradual evolution toward the 5G, with standards constantly evolving and evolving.

In recent years, with the deepening application of information technology in the industry, the society and the industry have gradually deepened their understanding of information security. NB-IoT and eMTC based on licensed spectrum can provide higher security. Access to the industry's mainstream technology vendors extensive support, users can make the technical capital and product investment to obtain basic protection, with product technical support and service continuity, continuity.

Relying on technology, security, service and other factors, will make NB-IoT and eMTC technology more and more leading market position.

They also have different characteristics for both NB-IoT and eMTC technologies.
