The most trusted open software for mobile wireless networks.

We’re unique in making our 4G & 5G UE & RAN source code available for fine-grained commercial customisation.

Our licensing model supports the full pathway from initial R&D exploration, through rapid prototyping to robust production network deployments.

We have developed our own UE and RAN solutions from the ground up for both 4G and 5G.

Benefits of Choosing SRS

Transparent Code

Software is not more trustworthy simply by virtue of being open. However, software which is open can be openly tested and audited by anyone. Our open software is used around the world. Greater scrutiny, feedback and continuous improvement increases the trustworthiness of our software.

Customisable

Well-written open software transforms the efficiency of engineering teams. Open software removes friction and barriers to innovation by allowing everyone to look under the hood. This means our customers can move faster to develop and launch innovative products and services.

Performant

However you compose your hardware, we have a high-performance software solution which runs on it. By providing complete applications for both UE and RAN, we have ownership of the entire system performance for the air interface of your network.

Portable

Our software is written in C/C++ with hardware-specific SIMD optimizations for platforms including x86, ARM and PowerPC. Our FPGA SoC solutions reuse the same portable C/C++ codebase on the processing system, adding high-performance DSP chains on the programmable logic to boost performance.

Licensing Pathway

Whether you’re carrying out early stage R&D, product prototyping or large scale deployment, our flexible licensing options will meet your needs at every stage of the journey. Our srsRAN project allows anyone to get started while our commercial source-code licenses support development and delivery of commercial products and services.

Expertise

At SRS, we have developed our own UE and RAN solutions from the ground up for both 4G and 5G. This gives us an unmatched level of insight into the complete mobile wireless network as well as the best tools to rapidly analyse, diagnose and address performance issues in any part of the network.

Deployable

Our software provides levels of robustness and stability required for commercial deployments. We achieve this reliability through exhaustive testing of our solutions at every stage of development and at every level from in-code unit-tests to end-to-end system testing, code analysis testing and conformance testing.

Test & Measurement

Our software suite contains every building block needed to construct any 4G/5G wireless application you can imagine. We exploit this to build our own instruments and test harnesses to isolate any network element for analysis. Current solutions include AirScope and CoreScope.
