The Ligado case tests whether government-issued spectrum licenses amount to protected property rights—and whether blocking their use constitutes a Fifth Amendment taking.

When optical materials (molecules or solid-state semiconductors) are embedded in tiny photonic boxes, known as optical ...

The bandgap defines how insulators absorb light and conduct electricity. XUV high-harmonic interferometry now lets ...

Abstract: A simply structured distributed estimator is described for estimating the state of a continuous-time, jointly observable, input free, multi-channel linear system whose sensed outputs are ...

Abstract: Proximal spectrum sharing allows users to connect to nearby base stations (BSs) of other operators based on SINR, improving spectral efficiency and user experience. However, it raises ...

Four of Peru’s mobile operators – Bitel, Claro, Entel and Integratel - have obtained spectrum for 5G deployment. A fifth, Americatel, which had prequalified for the bidding process, reportedly did not ...
