The development of educational information processes and information technology has made it possible to build a remote learning environment for English education. The application of fifth-generation communication (5G) has carried out revolutions in education for both teachers and students. In this study, an optimization approach is presented for English teaching mode to overcome the limits of current college English teaching settings and broaden the span of 5G technology. The proposed optimization technique varies from traditional college English teaching methods in that it integrates 5G, which considerably increases the communication of college English classes. Furthermore, the optimization technique can promote the standard of English teaching in several ways while completely and systematically following the teaching principle of "teach students according to their capabilities." In addition, a Bat Optimization Algorithm (BOA) is employed to enhance the process of transmission and measure the students' cognitive skills. The experimental results show that the proposed method addresses the limitations of the traditional English teaching model in colleges while enhancing students' cognitive skills in a variety of areas, including listening, speaking, reading, and writing.
