BT and Huawei have been busy at the annual Mobile World Congress (MWC) in Barcelona this year, unveiling details of their 5G network slicing research.

Network slicing allows specific ‘slices’ within an IP-based network to be ring-fenced and reserved for particular activities. This allows individual services to remain unaffected by bandwidth demands on the network as a whole, and to have specific policies applied to traffic being carried over a particular ‘slice’ – especially relevant when services are business-critical. BT’s CEO of Technology, Service & Operations Howard Watson and Chief Architect Neil McRae explained more about the exciting opportunities 5G presents for mobile during a visit to MWC.

5G is a big focus for BT, which last year also announced that it would be working with Nokia on research into 5G technologies.


Integrating the best capabilities of fixed and mobile networks, 5G will deliver seamless connectivity which is even more capable than today’s 4G technologies. It will deliver greatly improved ultra-fast speeds to mobile users and target peak rates of multiple gigabits and latency in the range of one millisecond.
