REISSUED - Opportunity: Single Channel Full Duplex Techniques for Satellite Communications (ARTES FPE 1B.133)

In most satellite communication systems, full duplex operation (i.e., simultaneous transmit and receive functionality) is achieved by using two separate frequency channels with spectral filtering employed to achieve the required isolation between signals. With ever-increasing data volume demands accompanied by pressure to reduce the cost per bit delivered, new techniques to utilise the available radio frequency (RF) spectrum more efficiently are continually needed. Simultaneously transmitting and receiving information in a single frequency channel has already proven a viable approach in other wireless communication application domains and has the potential to double total system throughput. Such systems typically employ a combination of both analogue and digital Self-Interference Cancellation (SIC) techniques, together with a careful antenna design and a suitable placement, to achieve the necessary isolation between transmit and receive signals, and such techniques have therefore advanced rapidly over the last few years. Single channel full duplex operation has consequently been supported within consumer (cable) networks since the release of the Data Over Cable Service Interface Specification (DOCSIS) 4.0 in 2017, and integrated wireless access and backhaul for 5G using full duplex is also now becoming a reality. Long-Term Evolution (LTE) products are already available using full duplex such as LTE User Equipment Relays which enable a small cell LTE eNodeB to backhaul to an LTE macro base station using the same access frequencies for both the small cell and the macro network.

5G end-to-end link first at ESA 5G hub

A demonstration at the ESA/ECSAT facilities in Harwell today achieved the first 5G full end-to-end link through a Low Earth Orbit (LEO) satellite constellation. The event used a super compact electronic antenna terminal, powered by SatixFy UK, to connect to the Low Earth Orbit satellite constellation operated by OneWeb. 

ESA boosts the satellite-enabled 5G media market

Film fans, gamers and future metaverse users will be able to experience high-quality videos, games and extended reality environments live and uninterrupted from anywhere, as satellites link up with terrestrial-based next-generation 5G and 6G connectivity.

Iris system to digitalise airspace goes global

A space-enabled system to help clear congested skies while reducing carbon emissions is going global, following a deal signed today between satellite communications provider Inmarsat and ESA.
