More than 10Gbit/s @ more than 100GHz!

Over the last decades, wireless communications have evolved in order to support an ever-increasing throughput thanks to higher bandwidth, spatial multiplexing, and improved implementation of advanced communication schemes. Currently this is peaking on the cellular side with upcoming 5G networks and on the local access side with IEEE 802.11ac/ax and 802.11ad/ay standards, at frequencies of 5-6 GHz and 60 GHz, respectively.


While those standards deliver a high throughput - around 7 Gbit/s for 11ac and 11ad - there are applications for which this is either not sufficient in throughput or coming at an excessive power consumption. IMEC is working on applications requiring a throughput possibly larger than 10 Gbit/s. In some scenarios multiple users may use the same technology in the same room, further boosting the throughput requirements. Moreover, battery-powered devices will not be able to support the power consumption of existing solutions and drastic improvements are required.


In this topic, we propose to revisit communication schemes targeting those applications by considering the following options or constraints:

  • Use of higher frequencies - such as 140 or 300 GHz - where a very wide bandwidth is available
  • Hardware-asymmetric links where the mobile terminal is power constrained and the access point is much less power constrained
  • Simplified communication schemes, such as non-coherent modulations or receiver architectures without equalization
  • Investigation and optimization of analog/digital partitioning trade-offs based on technology evolution
