Common elements of modern lifestyles, like attending video conferences, streaming TV dramas and shopping online, require an information superhighway to transmit data. However, the high volume of traffic on the highway leads to frequent jams, resulting in data loss and sluggish images. Professor Raymond Yeung Wai-ho’s network coding theory offers a solution. His project “Network Coding for Next Generation Networks” was among the first batch of research projects accepted into the RAISe+ Scheme this year. The project will primarily concentrate on the deployment of BATched Sparse (BATS) code, which greatly increases the network transmission rate and reduces distortion caused by data loss. Professor Yeung’s project targets three critical domains: cellular networks, smart cities and data centres. Besides undertaking the necessary R&D, his team aims to expedite the market introduction of their innovative products by collaborating with industrial partners. He hopes that BATS code will help realise Hong Kong’s smart city vision and its 5G infrastructure-based development, and make it a world-class smart city.
