IEEE Approves Standard to Support Low-Frequency, Narrowband Power-Line Communications and Smart-Grid Applications
The IEEE announced today that it has approved IEEE 1901.2, “Standard for Low-Frequency (less than 500kHz) Narrowband Power-Line Communications for Smart-Grid Applications.” The achievement was driven and sponsored by the Power-Line Communications Standards Committee of the IEEE Communications Society (ComSoc). “Created to specify secure PLC at data rates up to 500kbps and at … [Read more...]
Robot Arm Aids in High Frequency Antenna Calibration Breakthrough
A new antenna testing method from researchers at the Physical Measurement Laboratory (PML) in Colorado could lead to greater accuracy in the characterization and calibration of antennas for use at 50 GHz to 500 GHz. Currently, “there are no international reference standards for antennas at these frequencies,” team member David Novotny of the Radio-Frequency Fields Group in … [Read more...]
Analysis on Shielding Effectiveness of Board Level Shielding with Apertures
Brian She Laird Technologies ABSTRACT There is a growing need to evaluate the shielding effectiveness (SE) of board level shielding (BLS). By means of a reverberation chamber, we performed a series of shielding effectiveness test for board level shielding products with different apertures. In addition, an analytical SE formulation has been developed in comparison with … [Read more...]
