Freeing Spectrum from Jammers

January 21

The practice of jamming cell phone signals is illegal in the United States, but that does not mean it does not exist. Recently, wideband interference from a jammer in a Mexico prison near the border was noticed by multiple US wireless carriers. Unfortunately, while jammers prevent the use of unauthorized phones inside prisons, they create problems outside the prison walls by interfering with normal cellular traffic that uses the same frequencies as the phones inside. In this case, even with the jammer’s transmission power reduced in response to regulatory intervention, performance was degraded at many cell sites in the area. ISCO’s Dynamic Spectrum Recovery significantly improved KPIs on all sectors, most notably increasing connected users and downlink volume and throughput by over 100%.
