J-Shield is a robust filter on Javad GNSS antennas that blocks out-of-band interference (Figure 1). In particular, J-Shield blocks signals that are near the GNSS bands, including the proposed Ligado ...

Interference filters are frequently employed in transmissive configurations where the light passes through the filter to produce a specific effect (band-pass, long-pass, short-pass, among others).

Based upon lessons learned from the LightSquared situation, the author identifies important considerations for GPS spectrum interference standards, recommended by the PNT EXCOM for future commercial ...

Interference is becoming more common and more severe in today’s increasingly crowded wireless spectrum. Given the complex and dynamic nature of many wireless signals, equally dynamic measurement tools ...

Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, ...

Widespread availability of Wi-Fi functionality on smart devices, the potential for an overall improved quality of service (QoS), and the ability to stream video to smartphones in dense environments ...

The telecom regulator has decided to allocate additional lower-band spectrum to mobile operators through an auction process, aiming to improve network coverage, indoor connectivity and rural service ...
