The POSEIDON project aims at defining solutions for scalable CF-mMIMO operating in the sub-6GHz frequencybands where the available spectral resources are scarce. In particular, scalable CF-mMIMO architectures must beable to handle i) to support the dramatic increase in wireless traffic demand, which is caused by the exponentialgrowth of connected wireless devices, and ii) the emerging services/applications requiring huge data traffic (e.g.,high-quality video calls, holographic communications and Internet of Things/mMTC). Moreover, as an additionaltarget, POSEIDON will propose architectures that may contribute in the roadmap for the necessary transition togreener solutions and infrastructures. With the ICT sector’s power consumption increasing exponentially throughthe different generations of radio mobile networks, a tenfold increase of the power consumption for the wireless ac-cess is expected over the next decade. Thus, power consumption is among the critical key performance indicators(KPIs) to be optimized in 6G networks. To this end, POSEIDON will provide solutions to satisfy the expected 6G’srequirements with ever-increasingly ubiquitous and reliable wireless connectivity while at the same time steadilyaddressing the crucial reduction of the ecological impact of cellular infrastructures. The project will focus on lowerlayers, physical and access, of CF-mMIMO where the consequences of these aforementioned objectives are di-rect and challenging. WP4 aims at evaluating the benefits of the innovative solutions proposed in WP2 & 3 basedon the scenarios and models defined in WP1. A comparison to the reference cellular co-localized mMIMO is thecornerstone of this assessment. Developing a hardware-based proof-of-concept (PoC) of a CF-mMIMO system ischallenging and requires a heavy investment in time and budget. Thus, it has been preferred to rely on a softwarePoC derived from Siradel tool “S_5GConnect”. The benefits of POSEIDON techniques will be assessed by con-sidering the deployment constraints of both the access and fronthaul layers as well as the evaluation of end-to-endenergy metrics.
