With the continuous development of communication technology, 5G shielding devices will face higher technical challenges. In the future, blockers need to have higher frequency band coverage and stronger interference capabilities to adapt to more complex communication environments. While pursuing technological performance, environmental protection and energy conservation will also become an important direction for the development of 5G shielding devices in the future. By adopting more environmentally friendly materials and energy-saving technologies, the energy consumption and pollution of shielding devices can be reduced, achieving sustainable development. With the development of the Internet of Things and artificial intelligence technology, future blockers will achieve intelligent management. By integrating technologies such as sensors, control systems, and data analysis, remote monitoring, automatic adjustment, and intelligent warning functions can be achieved to improve management efficiency and security. The widespread application of shielding devices requires continuous improvement of relevant laws and regulations. The government should strengthen the supervision and management of shielding devices to ensure that they play a positive role under the premise of legality and compliance. At the same time, it is also necessary to strengthen the protection of personal privacy and communication freedom, and avoid the negative impact caused by the misuse of blockers.
