The testbed consists of separately managed 4G and 5G RAN and core-network segments. The 5G segment has been designed to employ the best of evolving NFV and SDN implementations and features. This architecture is able to inter-connect with and support different RAN configurations, C-RAN, D-RAN etc., according to available transmission options. The testbed currently covers the whole of the main campus of the University of Surrey, which spans an area of around 4km². The RAN segment of the testbed is illustrated below.

The Outdoor deployment, consists of 4G ultra-dense C-RAN comprising 3 macro cells (Lte-A TDD, tri-sector), plus 39 Lte-A TDD small-cell sites, all operating at 2.6 GHz (BW = 2x 20 MHz ; 4×4 MIMO) as well as 1x 4G FDD site operating at 700 MHz ; (BW = 10/20 MHz ; 2×2 MIMO), and 8x 5G NR TDD sites, operating at 3.5 GHz (BW = 100 MHz; 64×64 MIMO). Additionally, 28 GHz (PtP), 60GHz (PtMP) mmWave and satellite backhauling are also supported. The Indoor deployment (Lte-A based C-RAN) consists of 6x TDD and 6x FDD cells over 2 floors, and Wi-Fi APs. The Core Network supports separate 4G and 5G core segments.   The 4G segment is based on Rel-14 EPC ‘CUPS’. The 5G segment supports virtualised core functions and Rel-15 features such as Context Awareness and simplified control plane. The testbed also supports edge computing to demonstrate MEC (co-located with the access nodes deployed at the campus) capabilities.
