Shanghai General Hospital signed an agreement with China Mobile Shanghai branch on Thursday to establish a 5G technology-based treatment center. 5G technology will  improve the efficiency of first aid, in-hospital services and follow-up management as well as long-distance education, consultation and communication, said Dr Zheng Xingdong, president of Shanghai General Hospital. A 5G-based emergency treatment system can greatly improve first aid. The first four minutes are vital in treatment of urgent cerebral-cardio vascular diseases like stroke.
