Nokia operates an LTE/5G test network in Ulm, Germany. Four antenna sites are connected with optical cables to the 5G base station (gNB) located in the Nokia laboratory. The 5G core’s UPFs, which are responsible for routing and forwarding user data between the gNBs
and the external Data Networks (DN), are also located in the Nokia laboratory. So is the EDGE Server, on which Data Networks (DNs) for
5G-IANA are hosted.
The EDGE Server provides computing resources at the “edge” of the mobile network and close to the mobile user. Due to the co-location of gNB, UPF(s), and EDGE Server, and the use of optical fibre between gNB and the antenna sites, the latency of user data traffic between an antenna site and the EDGE Server is below 1ms.
Network Slicing is used to allocate network resources to fulfil the requirements of specific services. Nokia will provide two preconfigured network slices – one for Enhanced Mobile Broadband (eMBB) and one for Vehicular to Everything (V2X).
The area at antenna site “DRK Ulm” will be used for the 5G-IANA use case testing. Figure 2 indicates the two currently available sector cells of this site, and the enclosed parking area near this antenna site, which can be booked on weekends for use case testing. Each cell sector operates in the frequency range from 2575-2615MHz (band b38 resp. band b41/TDD) with an UL/DL radio resource split of 30/70. Figure 2 also indicates maximum uplink and downlink cell throughput rates available at the parking spot.
