Automaker Coalition Urges FCC to Test Plans For Vehicle Connectivity Spectrum Sharing
A coalition of automakers has urged the Federal Communications Commission not to move forward with a plan to use part of the wireless spectrum allocated for vehicle connectivity for Internet access until testing can be completed to ensure it won’t interfere with future planned vehicle-to- vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. The Alliance of … [Read more...]
Noise-Removal Technology Could Increase Internet Speed Up to 400Gb/s
Researchers from Bell Laboratories in New Jersey have discovered a method to improve data speeds using twin, mirrored beams of light to strengthen data signal quality over longer distances. Typical fiber optic cables use a single beam of light to transmit information and are limited in power and consequentially, distance. While larger distances require more power to transmit … [Read more...]
Limitation of Voltage Changes, Voltage Fluctuations and Flicker in Public Low-Voltage Supply Systems
From the International Electrotechnical Commission webstore: “IEC 61000-3-3:2013 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by equipment tested under specified conditions and gives guidance on methods of assessment. It is applicable to electrical … [Read more...]
Capacitors for Antenna Tuning and Impedance Matching Applications
Peregrine Semiconductor Corporation, a provider of high-performance radio frequency integrated circuits (RFICs) has released the PE64906, PE64907, PE64908 and PE64909digitally tunable capacitors for wireless applications Featuring a capacitance range of 0.6-7.7 pF and support power handling up to 34dBm into 50 ohms (30 Vpk RF), the new capacitors “provide an easy-to-use … [Read more...]
Togetherness is Another Way of Saying Well Bonded
Electromagnetic compatibility (EMC) is often described in terms of RF coupling phenomena. Usually the big four: Radiated and Conducted Emission and Radiated and Conducted Susceptibility/Immunity. These four elements cover all of the EMC issues in a very broad sense. Occasionally lightning and ESD will be divorced from susceptibility and described as if these two items were … [Read more...]
