Considering the characteristics of NB-IoT, NB-IoT technology can meet low-power, deep-coverage, high-capacity low-rate and delay-sensitive services. An NB-IoT base station can build 6 sectors, and a sector can build 50,000 nodes. It has super coverage capability and can be widely used in remote meter reading, intelligent parking, intelligent street lights and other fields.
Huawei plays an important role in the evolution of NB-IoT
On the road to NB-IoT evolution, Huawei and Qualcomm played an extremely important role. In 2015, Huawei and Qualcomm announced an IoT convergence solution that uses FDMA multiple access in the uplink and OFDM multiple access in the downlink. This convergence has shaken the industry.
On June 16, 2016, this was the most important day for the cellular IoT industry. The 72nd meeting of the 3GPP RAN Plenary held in Busan, South Korea, was successfully concluded. NB-IoT (Narrow Band Internet of Things) is an important topic of 3GPP R13, and its corresponding 3GPP protocol-related content has been approved by the RAN Plenary, officially proclaiming this NB-IoT widely supported by the wireless industry. The standard core protocol has been fully completed after more than two years of research.
As the only Chinese equipment manufacturer, Huawei put forward the idea of ​​narrowband design, and theoretically demonstrated that the uplink narrowband can bring a capacity increase above the order of magnitude in the coverage-limited area, laying a solid foundation for the subsequent development of NB-IoT. Its classic narrow-band lifting capacity formula is also widely used. In addition, Huawei also pioneered the concept of uplink 3.75kHz LTE, systematically expounding the design concept of the 180kHz narrowband system and the potential benefits. Including GSM, UMTS, LTE can be deployed together. For example, in the GSM Refarming scenario, this 180 kHz narrowband system can be deployed by taking out a GSM carrier 200 kHz resource. In addition, the 180kHz narrowband system can also be deployed in the LTE protection band, and these design ideas have become the basis of the NB-IoT standard.
