Specialization introduction

Major introduction

It studies how to transmit and process information efficiently and reliably, serving as the core foundation for technologies such as 5G/6G, IoT, and satellite communications.

Program overview

Communication and Information Systems is a core direction under the Information and Communication Engineering discipline. Simply put, it studies 'how to transmit information from point A to point B quickly and accurately.' You will learn courses such as Signals and Systems, Digital Communications, Wireless Communications, Coding Theory, and Network Protocols, and use tools like MATLAB, Python, and FPGA for simulations and experiments. This major suits students who enjoy math and physics, are curious about electronic devices and networks, and are willing to debug code or circuits. Chinese universities have strong research capabilities in 5G/6G, optical communications, satellite internet, etc. Many labs collaborate closely with companies, offering access to cutting-edge projects.

Major prospects

通信行业一直在变，从4G到5G，现在又在推6G、卫星互联网、车联网、工业物联网。中国是全世界最大的通信市场之一，华为、中兴、三大运营商以及大量初创公司都在招人。国际学生如果对无线通信、光通信、信号处理感兴趣，可以关注中国在“新基建”中的5G基站、光纤网络、低轨卫星等项目。另外，人工智能和通信结合（比如智能信号处理、网络优化）也是热门方向，未来十年需求会持续增长。

Career prospects

毕业后可以去通信设备商（如华为、中兴、爱立信）、运营商（中国移动、联通、电信）、互联网公司（如腾讯、阿里做网络架构）、芯片公司（高通、联发科、海思）、研究所（如中国信通院）等。常见岗位有通信算法工程师、射频工程师、网络协议工程师、系统测试工程师、技术支持工程师等。薪资方面，硕士应届生在中国一线城市（北京、上海、深圳）起薪通常在20万-35万人民币/年，有经验的资深工程师可以到50万以上。国际学生如果中文流利，进外企或中企海外部门也有优势。
