This research project puts focus on modulation and coding schemes for Gbit/s Plesiochronous Digital Hierarchy (PDH) links with a short- to medium-term application horizon, Gigabit Ethernet based microwave radio links and networks, and more long-term research on packet based microwave backhauling networks. In particular, impact and opportunities with the envisioned Coordinated MultiPoint (CoMP) solutions in the next generation RANs will be investigated.
Innovations in the project are expected in the areas: Hardware impairment and compensation techniques; modulation and coding techniques for high speed circuit and packet based links; and improved microwave radio backhaul network topologies for future cellular RANs.
Rapidly increasing data volumes in mobile radio access networks (RANs) puts new challenges on microwave backhauling. The future market requirement for microwave backhauling is expected to move towards more efficient packet based transport solutions, in particular to carry Gigabit Ethernet traffic. There are two possibilities; support Gigabit Ethernet in currently defined frequency bands within 5-38 GHz, and/or design new microwave radio links for carrier frequencies in the range of 70-80 GHz.
The MAGIC project involving Chalmers University of Technology, Ericsson AB and Qamcom Technology AB will in various ways target all three key areas defined in the VINNOVA vision for future faster, smarter and convergent Information and Communication Technologies (ICT): faster backhaul through higher backhaul data rates, smarter backhaul through packet enabled and dynamic CoMP aware backhauling, and convergent backhauling through exploration of interaction mechanisms with the cellular RAN.
