HC Security Network News NB-IoT refers to a narrow band of things (NarrowBand-InternetofThings) technology, quite literally, NB-IoT use of existing base station communicates, users need not wire, having a stronger signal than a cell phone coverage It also supports low-power management, achieving a wider range of IoT signal coverage communication in a low-cost, low-power mode. The NB-IOT door lock is to connect the device to the Internet of Things and remotely monitor the door lock. Management, NB-IOT is recognized as the most promising future IoT communication solution. Imagine that the home's lights, refrigerators, curtains, air conditioners, toilets, dogs... can easily be controlled by NB-IOT. Isn't it NB?
Major telecom companies in the world are already running and deploying NB-IOT networks. China Telecom and Huawei will cooperate in September 2017 to open the NB-IOT network nationwide. The first pilot unit of Beijing Telecom is Tsinghua University. Various departments of Tsinghua University work together to create a national model project for NB-IOT applications in universities. The first phase selects smart water meters and smart trash cans (yes, smart garbage) Bucket), smart bicycle and NB-IOT door lock.
With the positioning of the first school apartment locks and the outstanding performance of more than 100 wireless networked door lock users, AnXuntong has become the preferred cooperative development partner of Tsinghua University NB-IOT door locks.
Demonstration of NB-IOT door locks for leaders of Tsinghua University, Beijing Telecom and Huawei Group is equivalent to our big test, real-time monitoring of door lock status, use of NB-IOT to issue permissions, when the network is abnormal, the right to send via Bluetooth via mobile phone, remote Unlocking, emergency alarms, data acquisition and analysis, low-power testing, student self-charging... All functions are demonstrated once!
“It’s very excitingâ€, “the industry’s firstâ€, “the university’s leadingâ€, “this is a company worthy of cooperationâ€... The leaders’ praise and wide praise are the high priority and fully affirmed the technology of AnXuntong. At the same time, it also means that the first real NB-IOT door lock in the country was officially born!
