Overview
Ubiquisys, the developer of intelligent cells, and the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), the leading research organization in communication technologies, are working together to develop the world’s first open source product-oriented LTE network simulator.
The simulator will provide a common platform for LTE femto vendors and LTE macro vendors to evaluate their different solutions. The advantage for operators is that they can be sure that large and small cells from different vendors will work harmoniously before they are deployed.
In WCDMA networks, femtocells and macro cells work independently, but in LTE all cells work together as a single SON. This means that the adaptive behaviour of femtocells and macro cells is interdependent.
Simulators are important because they can evaluate product behaviour in a mature, densely deployed and heavily used network, at a time when real deployments are in their infancy. Ubiquisys made extensive use of a WCDMA network simulator during the development of its first generation of intelligent femtocells.
The open source LTE simulator is based on the popular ns-3 network simulator for internet systems. The development of the LTE simulator is open to the community in order to foster early adoption and contributions by industrial and academic partners.
Development
Source Code Repositories
The source code released by the LENA project is available at http://lena.cttc.es/hg/lena/
You can download the latest release of the code using this command:
hg clone http://lena.cttc.es/hg/lena/
Model Documentation
The LTE-EPC model developed within the LENA project comes with the following documentation:
- design documentation
- user documentation
- testing documentation
- profiling documentation
This documentation is available both in html format and in pdf format.
Following the ns-3 guidelines, the source of the documentation is maintained in .rst format and is stored in the mercurial repository alongside with the source code.
API Documentation
The API documentation of the code implementing the LTE-EPC model is also available html format. This is generated using doxygen following the ns-3 guidelines, hence it includes not only the LTE-EPC API but also the complete ns-3 API.
How to contribute
The development of the ns-3 LTE module is still ongoing and open to contributions by the community.
If you are interested in collaborating feel free to drop an email to Nicola Baldo, the LENA project leader at CTTC (nbaldo at cttc dot es).
