T-Mobile recently submitted to the FCC a study comparing Managed Access Systems (“MAS”) and precision jamming systems (micro-jamming) as potential solutions to prevent contraband phone use in correctional facilities. This study was submitted to Docket 13-111, Promoting Technological Solutions to Combat Contraband Wireless Device Use in Correctional Facilities. The study provides an overview of MAS and micro-jamming solutions examining both technical and cost considerations. The paper finds that the cost to deploy and operate the […]
