The machine rope jump, also known as a bungee, is a very exciting outdoor recreational activity that has emerged in recent years. The skipper stands more than about 40 meters (a high bridge, a tower top, a high building, a crane or even a hot air balloon, ties a long rubber strip fixed at one end at the ankle joint, then stretches the two arms, closes the two legs, and jumps with the head down.
The rubber band attached to the ankle of the jumper is long enough to allow the jumper to enjoy a few seconds of "free fall" in the air. When the human body falls to a certain distance from the ground, the rubber rope is pulled and tightened to prevent the human body from continuously falling, when the human body reaches the lowest point, the rubber is bounced again, the human body is pulled, and then the human body falls again, so that the bungee jumping process is repeated for many times until the elasticity of the rubber rope disappears.
At present, the mechanical cable jumping is used as a high-risk amusement project, and the accident probability that the human body falls off the protective rope body which is maintained by the mechanical cable jumping exists in multiple operations is caused by the aging of equipment and manual misoperation.

The characteristics and communication benefits of mobile communication systems employing different duplex modes are different. The uplink and downlink channels in the TDD mode mobile communication system use the same frequency, and thus have reciprocity of the uplink and downlink channels, which brings many advantages to the TDD mode mobile communication system.
In TDD mode, the transmission of information in uplink and downlink can be performed on the same carrier frequency, i.e. the transmission of information in uplink and the transmission of information in downlink are realized by time division on the same carrier.
