The world is now using the 4-G wireless systems but the research community is already hard at work creating the next generation 5-G wireless systems, expected to arrive by 2020. What sets the future 5-G apart from the current 4-G? It will have a data capacity 1000 times greater, connecting up 1000 times more devices with energy efficiency 1000 times better, translating into faster bit rate and significantly lower latency. In addition, it will support new application scenarios such as machine-to-machine communications. Such goals are not easily achievable. Earlier speaking in the HKUST’s Science-for-Lunch Talk, Prof Vincent Lau has shared the new vision and applications as well as technical challenges and opportunities.
