This reporter learned from Guangdong Mobile, recently, Guangdong Mobile is actively promoting the "big connection" strategy, accelerate the construction of cellular Internet of things and application exploration, has been in Guangzhou, Shenzhen, Zhuhai, Foshan and other places to pilot the opening of the 249 cellular Internet of things site, and take the lead in the completion of the intelligent parking, water quality monitoring and other business application testing.

Cellular IoT is an IoT technology based on existing mobile cellular networks, of which Narrowband IoT (NB-IoT) is one of the important branches. Narrowband IoT has the advantages of wide coverage, multi-connectivity and low power consumption, which can effectively meet the service needs of industry, public and family.

In the IoT application demonstration site in Qianhai, Shenzhen, users can view the available parking spaces in the "Qianhai NB-IoT Demonstration Area" in real time through the cell phone APP, and easily find vacant parking spaces and experience intelligent parking services. According to the staff introduction, compared with other parking management technology, based on the narrowband Internet of Things (NB-IoT) intelligent parking services with carrier-level network security capabilities, greatly improving the reliability, security, and can provide more convenient parking services for the general public.

It is understood that Guangdong Mobile is currently accelerating the construction and testing of cellular IoT, giving full play to the advantages of leading technology, and opened 249 sites in just three months. In the next step, Guangdong Mobile will accelerate the network construction, and actively expand application services in parking, meter reading, smart wearable and other fields, laying a solid foundation for the construction of smart cities.
