Welcome to the FlexNets Initiative

FlexNets (Flexible Wireless Communications Systems and Networks) is an open-source research initiative that explores new means for leveraging the flexibility in radio communications. It provides a platform for collaborative research efforts on software-defined radio (SDR), cognitive radio, and similar concepts that promote flexibility in wireless communications. The mission of FlexNets is easing the design, development, and deployment of flexible radio communications systems and networks. FlexNets provides software tools for sharing hardware and software resources. It facilitates introducing real-time computing resource management approaches and testing them in different SDR scenarios.

Project Status

This project has evolved to ALOE++ and the Open Source LTE Deployment (OSLD). Please visit our new Web Sites:


ALOE++-0.2 has been released

  • ALOE++ is being designed under the OSLD Project supported by the NLnet Foundation. It will dramatically improve the signal processing performance while reducing the framework overhead. ALOE++ will be much easier to use and develop, encouraging cooperative development.
    • Check out the ALOE++ specs.
  • New ALOE version with OFDM Demo has been relased! Features: improved performance, reduced overhead, USRP support, improved GUI signal visualization, OFDM demo with 2-20 MHz bandwidth allocation

Previous Releases

  • ALOE: Abstraction Layer and Operating Environment (former PHAL-OE - Platform and Hardware Abstraction Layer Operating Environment) is a lightweight middleware that eases the deployment and portability of waveforms on multiprocessing platforms. => Go to QuickStartGuide to download and install ALOE latest version
  • FlexWaves: Flexible Radio Waves is a software repository containing waveform modules. UMTS and WiMAX waveforms are available. LTE is currently developed unde the OSLD Project.
  • FlexCRM: Flexible Computing Resource Management develops a flexible computing resource management framework for managing the distributed and limited computing resources of multiprocessing platforms and the real-time computing requirements of waveforms.
  • aloeUI: Graphical User Interface for ALOE provides a user-friendly control interface for loading and executing waveforms, displaying real-time signal evolution, capturing execution time statistics, etc.
  • ALOEedu: ALOE Education offers educational material on flexible wireless communications, including self-explanatory laboratory sessions.
  • SDR Cloud Simulator is a tool for rapid evaluation and analysis of computing resource management for SDR clouds. Download at Uncompress the file and run gui.m from Matlab to launch the GUI (in the uncompressed directory).
