Arnold's Bifurcation Principle Applied to Radio Link Failure and Beam Failure Early Warning in Cellular Networks (4G/5G/6G)
Mobile phone connections drop for two related reasons: a narrow mmWave beam gets blocked, or a link of any kind simply fades out because the phone has moved into a weak coverage spot. Both problems are handled today by mechanisms that only react after the signal has already gone bad. This paper describes one small, fix...
