We present our vision for a departure from the established way of architecting and assessing
communication networks, by incorporating the semantics of information, defined not …

With numerous ongoing deployments owned by private companies and startups, dense
satellite constellations deployed in low Earth orbit (LEO) will play a major role in the near future …

The classical definition of network delay has been recently augmented by the concept of
information timeliness, or Age of Information (AoI). We analyze the network delay and the AoI in …

The next frontier towards truly ubiquitous connectivity is the use of Low Earth Orbit (LEO)
small-satellite constellations to support 5G and Beyond-5G (B5G) networks. Besides enhanced …

With the advent of 5G technology, the notion of latency got a prominent role in wireless
connectivity, serving as a proxy term for addressing the requirements for real-time communication…

We address the fundamental tradeoffs among latency, reliability and throughput in a cellular
network. The most important elements influencing the KPIs in a 4G network are identified, …

The promise of ubiquitous and super-fast connectivity for the upcoming years will be in large
part fulfilled by the addition of base stations and spectral aggregation. The resulting very …

Massive MIMO is considered to be one of the key technologies in the emerging 5G systems,
but also a concept applicable to other wireless systems. Exploiting the large number of …

In high-resolution Earth observation imagery, Low Earth Orbit (LEO) satellites capture and
transmit images to ground to create an updated map of an area of interest. Such maps provide …

Ultra-reliable low-latency communications (URLLC) entail the transmission of sporadic and
small packets, with low latency and very high reliability. Among many potential areas of …
