The unlocking command is transmitted by the mobile network, that is, in the cloud server of China Mobile, China Telecom and China Unicom.

Positioning relies on GPS

Thank you very much. Is the electric bicycle equipped with a CAT1 module, NB-IOT module or 4G module? What type of IoT card does it use?

4G or NB, I feel that NB is more commonly used because of its low power consumption.

There should be more NBs, and some can be unlocked with Bluetooth assistance

There should be no need for low power consumption, the battery on the bike is so big, and the shared bikes also have solar panels

The oldest one has GSM module communication

GPRS, 3G module

Later there was nbiot+bluetooth

There should also be a 4G CAT1 module at the back. I heard that Hello is using it.

It actually uses 4G modules and Bluetooth modules. 4G can be positioned, and mobile phones provide positioning API interfaces, but you have to pay for it.

I feel that it continues the framework of shared bicycles.
