Smart Shared Bicycle Lock
Currently, GPRS-based smart locks are widely used in the bicycle sharing industry. However, GPRS-based smart locks offer inadequate user experiences due to the limited coverage of GPRS networks. For example, in some areas with poor network coverage, it takes 5 to 10 seconds to unlock a bicycle and up to 25 seconds to pay for a ride.
Sometimes, the shared bicycles cannot even be unlocked. When the ambient temperature is low, the locks may also fail due to the limited battery capabilities. Moreover, high power consumption of the GPRS-based modules leads to short battery standby time. To maintain a longer battery life, manpower or solar power is required, which results in unpleasant user experience or high bicycle cost.
NB-IoT Enables Smart Shared Bicycle Lock
The NB-IoT-based shared bicycle lock solution provides extensive coverage and good user experiences. It ensures that users can properly unlock a shared bicycle in 3 seconds and pay for a ride within 5 seconds from any place. In addition, NB-IoT-based smart locks can work properly even in harsh environments at temperatures from –40°C to 85°C.
The NB-IoT-based shared bicycle lock solution also solves the problems of high power consumption and short battery life. If each bicycle is unlocked ten times a day, the battery life can last two or three years, almost the same as a bicycle lifecycle. The cost-saving NB-IoT modules reduce the bicycle cost to less than RMB 300 (or about USD $45) each.
Bicycle sharing has changed people’s commuting habits. The IoT platform helps effectively manage shared bicycles, define the business model, and generate healthy profits for operators and vertical industries.
Huawei, China Telecom, and Ofo have collaborated to complete the basic feature and performance tests on NB-IoT-based shared bicycles. One million NB-IoT-based Ofo bicycles are expected to be shared by the end of 2017.
