Detail analysis of the relevant 3GPP technical specifications and scientific literature
Implementation of 3GPP LTE or 5G NR protocols in C/C++
Implementation of high-performance signal-processing algorithms and protocols (L1 to L3)
Use MATLAB as reference implementation for initial validation
Develop proof-of-concept prototypes based on SDR testbeds (e.g. NI USRPs)
System integration and over-the-air trials
Interoperability testing with commercial off-the-shelf devices (USRP – COTS)

OAI software running on GPP can greatly simplify network access, reduce cost, increase flexibility, improve innovation, and accelerate time-to-market.
The OAI code can be adapted to different use cases, making it an ideal platform to explore 5G for new application areas.
OAI software suite enables industrial companies to deploy and operate their own 5G Private network.
OAI provides security in 5G deployments and contributes to sovereignty in 5G technologies.
