UK- India Testbed Technical Report (UKI-FNI project)


The UKI-FNI project will support the design, deployment and operation of joint testbeds for field trials of new Open-RAN systems, management software and components in diverse regulatory regimes. The testbed connecting India and UK will be used to develop advanced algorithms test innovative solutions in hardware, software and protocols that will support the future integration of high-speed mobile systems with metro and core optical communications networks. This testbed enables researchers to test the performance of new emerging Open RAN technology and beyond applications based on latency, bandwidth, quality of experience, signalling and various traffic, safeguard policy and security interests. It gives researchers, the ability to test new 6G algorithms before they are used in live commercial networks. This report provides some details about the UK-India testbed architecture, its topology, the hardware components, the communication protocols and link speeds. It also gives some information about the availability of test bed, how to access it and the types of experiments it could support.

Surrey Testbed Architecture

The 5G/6G Innovation Centre testbed covers four square kilometres of the University of Surrey campus, as shown in Figure 1, and offers 5G infrastructure including 4G and 5G core network and 4G and 5G radio access.

5G/6G Innovation Centre Testbed
Figure 1: 5G/6G Innovation Centre Testbed

The testbed supports domestic (UK) projects as well as European and International projects. Small and medium enterprises (SMEs) are in a partnership with the centre, in order to use the testbed to test different aspects of 5G technologies, such as 5G applications, cyber-security on 5G technology and 5G network slicing.

The testbed offers a multi-RAT facility covering the University Surrey campus, featuring both outdoor and indoor radio deployments, supporting for 4G/LTE and 5G/NR, both in non-standalone (NSA) and standalone (SA) modes.

As shown in Figure 1 the RAN is distributed over 44 outdoor sites, each providing either 4G/LTE, 5G/NR, or a possible combination of both. These are connected to the BBUs distributed across two machine rooms in the 5G/6GIC centre.

Regarding 4G, these include an outdoor coverage by an ultra-dense centralised RAN (C-RAN) consisting of 40 4G-TDD sites distributed into 56 cells of which 3 macro cells of 3 cells each. These 4G sites support 2.6GHz band, carrier aggregation (2CA) and 4×4 MIMO.

Concerning 5G, the testbed includes an outdoor coverage by a distributed RAN (D-RAN) consisting of 7 5G-TDD sites distributed in 9 cells with 3 BBUs, including support for enhanced Mobile Broadband (eMBB) communications and of ultra-reliable low latency communications (URLLC) RAN on one site of a single cell. These 5G sites support 3.5GHz band and advanced 64×64 MIMO.

Concerning indoor in the 5G/6GIC, the testbed supports coverage by a C-RAN consisting of 3 4G-TDD cells and a single 5G NSA pair, distributed across two floors in the ICS, covering 2.6GHz and 3.5GHz bands.

Concerning the core network, the testbed also features a 3GPP Release 15 and Release 16 4G and 5G compatible cores, designed and developed both for E-UTRA/NR dual connectivity (EN-DC) NSA control-plane user-plane separation evolved packet core (CUPS-EPC) and SA 5G scenarios, deployable as CNF/VNF.

With regards to infrastructure, the testbed hosts two server machine rooms hosting multiple physical computing facilities and broadband units (BBUs) for 4G and 5G.

The 5G/6GIC testbed is interconnected with the India Institute of Science (IISc) testbed via the topology reported in Figure 2. The radio architecture is based on 5G distributed RAN with RRU interconnected via CPRI optical cables to BBUs hosted in the 5G/6GIC datacentre. These have 10Gbit links to a 10Gbit SDN network patched up to our 5G core network and network operation centre deployed as VNF and linked up via JANET to the Internet.

The core network running at 5G/6GIC is running in the internal datacentre on a Dell PowerEdge R640 (see Figure 3) featuring two Intel Xeon Gold 5218 processors, twelve 64GB modules of RAM, two 1.92TB 12Gbps SSD drives and two 10GbE plus two 1GbE network ports.

The core network server runs an Ubuntu 20.04LTS operating system and is linked via an internal Palo Alto PA-5220 firewall through an IPSec tunnel with the IISc Sophos XG750 firewall, to form a virtual private network, as shown in Figure 4, with further plans to upgrade to a Netpath+/L2 VPN managed by JISC.
