"Difficult parking " has always been one of the urban traffic problems, with the popularity of urban vehicles, traffic pressure increased significantly, the parking problem has become a lot of city lingering trouble. From October 30 - November 1, "NB-IoT smart car park" system made a stage pose on the 2016 World Internet of Things Expo which held in Wuxi, has brought a new dawn for alleviating the old problem of parking.

Some people driving to the public will be inadvertently found some delicate changes of the parking area outside the exhibition hall while parking, each location of parking space is installed with a new equipment, cannot help but cause the owner's attention. It is equipped with NB-IoT network and NB-IoT intelligent car detector, as long as the vehicle parked on the parking spaces, NB-IoT intelligent car detector will automatically collect and spread the signal of vehicle's location, status, etc. and to achieve information exchange with the owners of the APP, the parking lot background management system, traffic control departments etc., making the participants can easily view the number of free parking spaces and the status of the specific parking spaces on the phone, to achieve the intelligent parking business functions of reserving the parking spaces in advance, looking for cars with guidance in the parking lot, but also to more dynamically and fully master the parking lot information through the parking lot management departments and traffic control department, to achieve efficient dispatch and supervision.

It is understood that the intelligent parking based on NB-IoT business is Wuxi Mobile's first standardized end-to-end NB-IoT network application project, will effectively promote the popularity of intelligent parking management for the majority of owners to bring practical convenience. In fact, many owners are not unfamiliar with intelligent parking, there is no lack of some intelligent parking system like "automatic gate" and "self-help payment". What is the main difference between NB-IoT smart parking and general intelligent parking technology?

"Mystery" lies in the smart parking business launched by Wuxi Mobile which to creat based on NB-IoT technology. NB-IoT (Narrow Band Internet of things) is a cellular-based narrowband networking technology, is the key access technology in the field of Internet of things in the future, with four major features: first, wide coverage, which will provide improved indoor network coverage, in the same frequency band, NB-IoT will expand 100 times than the existing network coverage area; second, with the ability to support massive connections, a sector of NB-IoT can support 100,000 connections; third, with lower power consumption, NB-IoT terminal module standby time can be up to 10 years; fourth, with the lower module cost, the expected single connection module does not exceed $ 5.

Careful citizens may find that the "intelligent" level of the indoor parking lot in the previous shopping mall will be relatively high, while the open air parking lot relying on manual guidance and manual charges. A main reason is that the operation of various intelligent devices needs to be with high stability, covering a wide range of networks, and the layout of the open parking lot is much more difficult than the indoor because of wiring restrictions. However the generation of NB-IoT intelligent parking system, relying on the advantages of NB-IoT technology in the wide coverage, strong accessing, low power consumption and low cost, just to solve the "intelligent" problem of the open outdoor parking lot.
