On February 22nd, ofo announced that it has reached a cooperation with China Telecom and Huawei, and the three parties will jointly develop a shared bicycle intelligent solution based on the new generation of Internet of Things NB-loT technology. According to the cooperation content, China Telecom will provide the most extensive wireless network resources for theo; Huawei will provide NB-IoT chips for ofo and provide network technical support.
According to technology, this is the first application of NB-loT technology in the field of shared bicycles. The NB-IOT shared bicycles of the three parties will have longer battery life, and the service life is 2-3 years. The unlocking is faster and the second can be realized. open. According to the ofo, the NB-IoT technology can achieve no dead angle of the signal, and can still be used normally in the complicated and harsh environment with poor signal and other signals such as underground parking.
The core links involved in sharing bicycles include finding a car, unlocking, returning a car and billing. When the current cellular network coverage is insufficient, the user often locks the car, and the state of the vehicle cannot be timely fed back to the cloud, and the billing and release can be delayed. vehicle. At the same time, the electronic lock using the traditional communication technology has higher power consumption, and the bicycle has to have a built-in micro power generation device, and the user's riding behavior locks the charging, which affects the user's riding experience and increases the probability of failure.
It is understood that the new NB-loT solution jointly developed by ofo and China Telecom and Huawei is composed of smart locks, connection chips, intelligent management systems and cloud services. It is based on the world-leading NB-, which will be commercialized in a few months. The loT network technology has better coverage and ultra-low power consumption than the traditional network, and is the solution that best meets the shared bicycle application scenario in the currently known technology.
Due to the better coverage performance of the NB-IoT, the unlocking response experience of the shared bicycle is very fast, and the “random password†can be realized through data transmission. In addition, the coverage strength of the NB-IoT network is 20 dB higher than that of the existing conventional network signal, which is equivalent to Wear more than 1-2 walls, even if the bicycle is parked in a remote corner and other areas where the signal is difficult to cover, users can easily unlock it.
Focusing on the low-power wide-coverage Internet of Things (IoT) market, NB-IoT is an emerging technology that can be widely used worldwide, with wide coverage, multiple connections, low speed, low cost, low power consumption, and excellent architecture. Technical advantages.
China Telecom operates the world's largest broadband Internet and technology-leading mobile communication network, providing customers with comprehensive information service capabilities and customer service channel systems across geographies and services. Huawei is the world's leading information and communication (ICT) solution. Solution providers, open partners and partners, build end-to-end solution advantages in telecommunications networks, enterprise networks, terminals and cloud computing.
Yu Quan, chief strategy officer of Huawei's wireless network product line, said: "Huawei has been actively promoting the entire NB-IoT technology process since 2013. Shared bicycles are typical low-power wide-area Internet of Things applications, NB-IoT is IoT technology designed for such scenarios. From chip to network, Huawei's end-to-end NB-IOT solution has been proven in more than 20 industry applications."
Yu Quan told the technology that the cost of the NB-IoT chip is very low and will be officially launched with the ofo commercials in a few months. The number of specific cooperation bicycles has not yet been determined. At the same time, he said that this technology is not exclusive and may consider cooperation with other shared bicycles in the future.
