RF loading impact on WCDMA jamming

The effect of a mobile jammer on wideband code division multiple access (WCDMA) networks is influenced by radio network loading. A model of the WCDMA access control algorithm was developed and used to investigate network performance under jamming and various loading conditions. Jamming effectiveness was found to become less predictable as the load was increased. Increased loading levels were also found to generally increase the range to target at which jamming occurs. The viability of utilizing high-speed, constant bit rate, circuit-switched data calls as surrogates for multiple low-rate voice calls in a test environment was investigated. High-speed, circuit-switched data calls were determined to be a poor surrogate for multiple low-rate voice calls.
