FCC Okays Test of Jamming Devices in DC Correctional Institution
In yet another development regarding the controversy of jamming calls placed by inmates on contraband cell phones, the Federal Communications Commission has granted the District of Columbia Department of Corrections permission to conduct a test on Thursday, January 8, 2009. Despite the legal ban on jamming radio waves within the United States, an FCC official characterized this … [Read more...]
Omni-Directional Antennas Target Broadband Spectrum Monitoring
Models 3180, 3181, and 3182 from ETS-Lindgren are a series of omni-directional, biconical antennas for monitoring broadband spectrum. In addition to receiving signals from every direction around the antenna axis, Models 3180 and 3182 feature optimized elements that forestall any splitting of the main radiation beam in the elevation cut. Models 3180 and 3182 cover the … [Read more...]

The Importance and Methods of Full Wave Simulation Validation
Regardless of the accuracy of the modeling tool, each modeling exercise requires some level of validation before simulation results can be trusted. Bruce Archambeault, Ph.D. and Samuel Connor IBM Research Triangle Park, NC The need to validate simulations and model results has never been more vital. Full-wave and quasi-static simulation tools using many different modeling … [Read more...]
Texas Officials Hope to Resolve Prison Phone Jamming Controversy
As this issue of the eNews was being prepared, Texas politicians and prison authorities were trying to sort out the dilemma of jamming illegal phone calls by incarcerated felons without running afoul of the 1934 federal law that bans interference with radio signals. Earlier this year, officials in South Carolina had conducted a successful test of a jamming device that … [Read more...]

Software Simulation Boosts the Efficacy of PCB Design
Adding an effective package to the design cycle can pinpoint areas critical to EMC compliance Dirk Müller, FlowCAD, Munich, GERMANY Ultimately, electromagnetic compatibility can be validated only in the measurement chamber with existing prototypes. Those tests are time consuming and expensive. There are various ideas for cutting the costs of testing with early software … [Read more...]
Laird Cuts Staffing and Closes Hungarian Plant
Laird plc., a global supplier of EMI shielding devices and antennas, is in the process of cutting its staff by around 5000 or 54 percent. The company is closing its manufacturing facility in Hungary, which has 500 employees, and will close or downsize three of its facilities in the U.S. Production from these sites will be transferred to Mexico and China. These steps will lead … [Read more...]
