To perform critical tasks such as emergency rescue and disaster relief in emergency communication and other scenarios, the Rapid Deployment System (RDS) has been developed to realize rapid construction of on-site network. RDS can be quickly and conveniently installed on regular vehicles (without the need of modification), and provides 4G-based communication services such as voice, dispatching, data transmission and video monitoring along the road and for the task site. At the same time, in scenarios where vehicles cannot reach, the RDS can be transported to the site by means of manual carrying or caster dragging so that the network can be constructed and connected.
