CROSSNET

Project Overview

Crosslayer Solutions and Network Support for Broadband Wireless Access (CrossNet) is a joint project between the Centre for Wireless Communications (CWC) and the Technical Research Centre of Finland (VTT). The project also has very close co-operation with NetHawk and Elektrobit (EB), which have their parallel related research projects. Other project partners are Nokia Devices and Nokia Siemens Networks. Project started in April 2008 and duration is planned to be two years.

Project Focus and Common Laboratory

The concrete goal of the project is to combine the existing expertise of radio access and networking technology amongst the project partners. The main application system is the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) system and standard. Major target in CrossNet is to create a software model to connect NetHawk’s network simulator and analyzing tools to CWC’s and VTT’s computer simulation models and testing tools and EB’s radio interface test systems. CWC’s main task is to build simulation models of 3GPP LTE MAC and RLC sublayers. Developed models will be connected to existing CWC’s PHY layer simulation model and NetHawk’s network tools. A common goal for all project partners is to build a CrossNet research laboratory. The anticipated integrated platform i.e. CrossNet Common Laboratory consists of existing technology building blocks provided by project partners: NetHawk, EB, VTT, Nokia Siemens Networks, Nokia Devices and CWC.

Wireless Evolution

The project is expected to provide information, understanding and solutions for the wireless system and transceiver technology evolution, and in particular on following issues:

  • Tools to connect L1/L2 simulators and test systems to network analyzers.
  • Support for new network and terminal development and product creation.
  • Support for test equipment development.
  • Tools to support crosslayer optimization and network research.
  • Solutions for testing standard protocols and protocol enhancements in a realistic and complete environment.
  • Understanding and technology basis for future cognitive, topologically varying networks.

Results:

  • Software models for PHY and RLC layers are ready
  • Integration in common laboratory has been started: NetHawk’s EAST LTE simulator, M5 analyzer, NSN’s LTE base station prototype have been connected.
