Open source NS-3 Network Simulator now has LTE-U capability that supports leading edge features from SpiderCloud’s Enterprise RAN.

Milpitas, California & Barcelona, Spain July 14, 2017 – SpiderCloud Wireless, Inc., the leading provider of scalable small cell systems, and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), the leading resource organization in communication technologies, today announced a successful collaboration that simulates SpiderCloud’s LTE-U performance and includes the developed LTE-U models into the widely used ns-3 network simulator.

In response to requests from USA based mobile operators to demonstrate benefits of SpiderCloud’s LTE-U implementation, SpiderCloud collaborated with the researchers at CTTC who, in 2015, had created the LTE-LAA extensions for the ns-3 simulator (https://www.nsnam.org/wiki/LAA-WiFi-Coexistence). The LTE-U collaboration resulted in modules for:

  • Reference LTE-U implementation based on Carrier-Sensing Adaptive Transmission (CSAT).
  • Wi-Fi baseband listener that replaces the basic energy detection mode defined in LTE-U reference implementation.

“Our collaboration in extending ns-3 will benefit academics, researchers, and technology providers around the globe with transparent and reproducible simulations,” said Lorenza Giupponi, Senior Researcher, CTTC. “The LTE-U simulation proves that the baseline implementation vs SpiderCloud specific implementation plays a dramatic role in improving network performance.”

SpiderCloud has used ns-3 to simulate LTE-U that demonstrates an average 20% performance gain via replacing basic energy detection with an innovative Wi-Fi baseband listener. The listener also improves the SON co-existence capabilities of E-RAN by quadrupling the sensing radius of each LTE-U radio. “SpiderCloud’s collaboration with the world class researchers at CTTC was very positive,” said Behrooz Parsay, Senior Vice-President of Engineering, SpiderCloud Wireless. “We were able to deliver test results to our interested mobile operators that can be independently reproduced and understood.”

The ns-3 network simulator including the LTE-U modules can be obtained at bitbucket.org/cttc-lena/ns-3-lena-dev-lte-u
