Project Name: LOOP - Coexistence and Optimization for LTE-RAN and WAN
Research Programme: EUREKA CELTIC
Total Financial Volume:
Duration: 30 months (01.05.2007 – 30.10.2009)
The B3G vision is tending towards a diverse wireless networking world where scenarios define that the user will be able to attain any service, at any time on effectively any network that is optimized for the application at hand. Thus creating a future global infrastructure where several systems can coexist to support transparent end-to-end communications, in an efficient, cost-effective manner (this is also commonly referred to as the so-called ABCS (Always Best Connected Systems) philosophy). The 3GPP vision initiated proceedings on this next generation network in 2004 by setting up a study group on UTRA-UTRAN Long Term Evolution (LTE). The proposed 3GPP System Architecture Evolution (SAE) will encompass an IP core network infrastructure with IP interfaces targeting multiple RATS (Radio Access Technologies), which will not only be restricted to 3GPP legacy systems such as UTRAN or GERAN, but will also have inherent open interfaces to accommodate Wireless Area Networks (WiFi, WiMax), and even wired technologies. Therefore, this motivated the formation of the LOOP project and this collective consortium have a common pre-competitive R&D interest to address interoperability/coexistence solutions, specifically between 3GPP LTE RAN and WAN (WiMAX and WLAN) to ensure their competitive position in the market and to have coexistence solutions in place for eventual commercial launch. In the scope of the LOOP project, we aim to address:
LOOP innovations will be demonstrated on a coexistence demonstration tool and on real WMAN networks, which will serve as a basis for evaluating the product true market potential targeting commercial launch.
In LOOP Sigint is contributing at the physical layer with radio planning and mobility activities.
