Satellite jamming and underperforming 5G networks
The year 2023 witnessed a divergence of interests among our visitors. While the stories surrounding Russia's satellite jamming signal operations in Ukraine and the performance issues encountered by 5G technology worldwide attracted significant attention, readers also displayed a strong inclination towards exploring the newest and most exceptional developments in the field. They were particularly eager to learn about the unprecedented data rate records being shattered and the novel approaches employed to safeguard identities and authentications.
Satellite disruption has reached an unparalleled minimum.
Russia’s ongoing invasion of Ukraine has, over its nearly two-year course, has revealed a lot about the current state of electronic warfare. In early 2023, it became clear that one new branch of electronic warfare was the jamming of low Earth orbit (LEO) communications satellites. These satellites—typically CubeSats, and orbiting 2,000 kilometers or lower—have brought new challenges to satellite jamming compared to their bus-sized geostationary brethren.
The need for LEO satellite constellations to regularly transfer signals to the next satellite as it comes into view is a significant aspect. These transfers occur at intervals of approximately 7 to 10 minutes, creating a window for jammers to interfere with the signal. Moreover, LEO satellites generally have limited space, computing resources, and power to implement security measures compared to larger satellites. Additionally, many of these satellites rely on off-the-shelf components, which often come with their own vulnerabilities.
