Mobile telephony: Leti looking at 5G

The future 5G mobile telephony standard will probably not be operational until 2020. However, Leti—which recently completed two EU-funded research projects on “post 4G” technology—is already shaping tomorrow’s 5G with partners like France Telecom, Alcatel-Lucent, Vodafone, Sagem, and Nokia Siemens Networks.
BeFemto, the first “post 4G” project, looked at femtocell systems, which will one day replace Wi-Fi indoors. Artist4G, the second such project, explored cooperative systems for outdoor deployment. Both projects tackled the ever-present problem of cell-to-cell interfaces. The research has been presented at ten international conferences and three patents have been filed. Further research is already underway.
