SRS offers mobile wireless SDR product solutions to suit your needs. Source code access and highly modular architectures make our UE, RAN and instrumentation products highly customisable. Custom APIs can easily be added to support third-party software or hardware modules for e.g. algorithmic extension or hardware acceleration. Fine-grained logging, packet capture and performance metrics provide a deep insight into system functionality and performance.
Each of our SDR solutions are available under commercial source-code license. Whether you are carrying out novel R&D, prototyping an early-stage product or deploying a large-scale network, we can provide a licensing model to fit your requirements.
Our test & measurement instruments, SRS Airscope and SRS CoreScope are available under binary application licenses for off-the-shelf deployment. Commercial source-code licenses are also available to support tight product and systems integration, customization and extension.
SRS UE
The SRS UE is a full-stack software radio User Equipment (UE) solution for 4G LTE and 5G NR.
Implemented in efficient and portable C/C++, the UE supports a wide range of baseband hardware platforms including x86, ARM and PowerPC. The generic baseband I/Q interface allows it to be used with most SDR front-ends including those based on Analog Devices and Lime Microsystems RFICs.
SRS UE supports 4G LTE and 5G NR in Non-Standalone (NSA) mode, with 5G NR Standalone (SA) available Q4 2021. Running in linux userspace, the UE integrates with the network stack and provides a virtual network interface for user applications. The UE supports both hard USIM card integration and soft USIM emulation.
SRS UE Embedded
The full-stack SRS embedded UE solution supports the Xilinx Zynq family of SoC devices. Currently targeting the Ultrascale+ MPSoC and RFSoC architectures, the UE takes advantage of programmable logic to run the high-speed DSP chains of the PHY layer while deploying complex PHY procedures and upper layers on the ARM-based processing system.
The embedded UE provides a powerful low-SWaP solution for mission-critical, custom-built network deployments. The Zynq Ultrascale+ family of devices already feature in a wide range of high-performance SDR platforms targeting low size, weight and power deployments and a broad range of chipsets that provide scalable FPGA resources according to use-case requirements. High-end SoCs provide ample resources for R&D prototyping and third-party module integration, while lower-end devices provide efficiency for large-scale deployments.
SRS ENB
The SRS ENB is a full-stack software radio eNodeB solution for 4G LTE and 5G NR Non-Standalone (NSA) networks.
Implemented in efficient and portable C/C++, the software supports a wide range of baseband hardware platforms including x86, ARM and PowerPC.
Running in userspace on standard linux operating systems, the SRS ENB can be used with any third-party core network supporting standard S1AP and GTP-U interfaces. Within the eNodeB stack itself, functional split interfaces including splits 6, 7 and 8 are supported. The split 8 baseband I/Q interface allows it to be used with most generic SDR front-ends including those based on Analog Devices and Lime Microsystems RFICs. Split 7 supports network deployment using commercial off-the-shelf ORAN RRU devices.
SRS ENB - Embedded
The SRS embedded ENB solution supports the NXP families of Qoriq and Layerscape communication processors.
Providing eNodeB stack layers 2 and 3, the ENB integrates with third-party PHY solutions using standard FAPI interface. The fully integrated solution has been tested and deployed with PHY, RU and EPC within large-scale, high-performance partner networks.
SRS GNB
The SRS GNB is a full-stack software radio gNodeB solution for 5G NR Standalone (SA) which will be commercially available in Q2 2022.
Implemented in efficient and portable C/C++, the GNB supports a wide range of baseband hardware platforms including x86, ARM and PowerPC. Supporting functional splits 7 and 8, the GNB can be deployed with off-the-shelf 5G ORAN RRUs or with generic SDR front-ends using baseband I/Q interfaces.
SRS AirScope
SRS AirScope is a software radio air interface analyzer for mobile wireless networks. Currently supporting 4G networks, 5G network support is coming in Q1 2022.
AirScope provides real-time over-the-air decoding capabilities for network analysis using whitebox compute hardware and generic off-the-shelf SDR frontends. AirScope captures the downlink signal of a local network, decodes the control channel for all active users in the cell and provides detailed cell-wide and per-user statistics via log files, packet captures and trace metrics.
- Observe all network activity, quickly troubleshoot problems and rapidly deploy solutions.
- Passively analyze end-user quality of experience for the complete cell, identify cell-edge users and flag potential coverage, congestion and interference issues.
- Monitor per-user DL and UL traffic volumes, examine cell load distribution and identify bandwidth hogs.
- Easily integrate AirScope with third-party tools using our non-proprietary signal capture formats.
- Wireshark packet captures and text-based logs provided as standard.
SRS AirScope is available under binary application licenses for off-the-shelf deployment. Commercial source-code licenses are also available to support tight product and systems integration, customization and extension.
SRS CoreScope
SRS CoreScope is a special-purpose test and performance analysis tool for 5G core networks.
Deployable as a mobile-edge application, CoreScope supports standard NGAP and GTP-U interfaces to 5G core networks to emulate control and data RAN traffic identical to that generated by real UE and gNodeB devices.
- Exercise core network functionality and analyze key performance metrics to quickly detect and resolve problems.
- Rapidly identify network misconfigurations and highlight bottlenecks.
- Test for security vulnerabilities and easily integrate CoreScope with third-party tools using our non-proprietary logging and packet capture outputs.
SRS CoreScope is available in source code form under an AGPL V3 license.
