Open a communication hub! "In the late autumn of the northern frontier, as the dawn begins to emerge, with a command, the information support team of a certain brigade of the 81st Group Army begins a full process network information element formation training. The chariot raced rapidly, and the dust was flying. After arriving at the designated area, each station quickly set up antennas, connected links, concealed disguises... In no time, a communication "sky network" was quickly woven. Inside the cabin, keyboards sound, screens flicker, and information flows. The communication network link is interrupted, please handle it quickly. "Upon receiving the special situation report, the operator quickly switched to wireless communication mode. The officers and soldiers went out for investigation and found that the backbone optical cable line had been blown off by the enemy. They immediately launched emergency repairs. After the optical cable line returned to normal, officers and soldiers continued to strengthen line protection and patrol to ensure the safety of the line. As a combat command is transmitted over long distances to the front-line unit, the wireless signal suddenly experiences significant noise. The commander quickly determined that the main frequency used was being interfered by the "enemy", so he quickly ordered the activation of the backup communication channel and switched to frequency hopping anti-interference mode. The smoothness of the combat command chain is related to command effectiveness and affects the outcome of the battlefield. This requires that regular training must be rigorous and organized based on practical needs The leader of the brigade introduced that in order to improve the quality and efficiency of daily training, they have constructed realistic battlefield environments, randomly embedded complex special situations, and carried out regular testing and adversarial training to comprehensively hone the unit's ability to connect networks and chains in complex environments. The location of the basic command post has been detected by an enemy high-altitude drone and immediately transferred As the training progresses, the guidance and adjustment team provides special situations on the spot. All elements respond to orders and work closely together to quickly carry out withdrawal and transfer. As soon as the officers and soldiers arrived at the designated area, the sky suddenly became overcast with dark clouds, and an unexpected heavy rain arrived. Satellite communication is affected by weather, and the signal continues to weaken, making it impossible for the front-line team to establish contact with the command post! "The communication link was interrupted, and the team's officers and soldiers quickly put into tense emergency response work. At the critical moment, communication technician Lu Xiqiang calmly handled the situation and skillfully carried out a series of operations. Quickly, the communication link was restored to smooth flow, and instructions were transmitted through the rain curtain to distant places... After the training ended, the participating officers and soldiers immediately conducted a review and discussion. By replaying videos, analyzing parameters, and other methods, everyone thoroughly investigates and presents problems, and provides suggestions and opinions. The on-site commander introduced that the next step is to continuously optimize the communication network construction plan for diversified battlefield environments, explore the formation of a "one case, one table, flexible and diverse" network information element grouping system, and comprehensively enhance the wartime anti-interference and communication capabilities.
