NICTA, Australia’s Information and Communications Technology (ICT) Research Centre of Excellence, has successfully demonstrated technology that reduces the amount of radio interference in 3G networks with femtocells. The test configuration used a universal radio communication tester from Rohde & Schwarz as one of the 3G devices connected to the femtocell.

Radio interference from other 3G connections is recognized as one of the top issues in femtocell networks and NICTA has developed technology to address such interference. A recent real-time proof-of-concept test in Canberra showed the NICTA femtocell connecting to multiple 3G devices. The test verified that NICTA’s uplink interference cancellation (ULIC) technology successfully and substantially reduced radio interference in the uplink. When integrated into system-on-chip products, this technology will increase service quality for 3G mobile devices, improve coverage and capacity, and minimize the impact on legacy wireless infrastructure.

The test configuration used an R&S®CMU300 universal radio communication tester that provided a test platform for validation of the InterfereX design and made development and testing easier through the graphical user interface and internal signal setup and generation options.

“Through our product portfolio, we support the development of new wireless communications technologies by keeping our finger on the pulse of the market,” said Anton Meßmer, director of Rohde & Schwarz mobile radio testers subdivision. “Our focus is on tracking all existing and new standards at a very early stage in order to cover the entire spectrum from development to mass production with our T&M solutions.”
