Abstract: This investigation outlines the importance of accurate radio propagation predictions in the planning for UMTS radio networks. The UMTS radio technology based on variable spreading DS-CDMA ...

Abstract: The ray-tracing (RT) algorithm has been used for accurately predicting the site-specific radio propagation characteristics, in spite of its computational intensity. Statistical models, on ...

Ham radio enables two-way communication, for hobby, public service and sports events. To transmit, you need to pass an exam and get a licence from the union government.

The world’s largest amateur radio convention returns to the Greene County Fair and Expo Center this weekend, with a slate of new and classic experiences for ham radio fans of all ages.

Unfortunately, that runs afoul of the physics of ionospheric propagation. Thanks to the physics of the interaction between radio waves and the charged particles between about 50 km and 600 km ...

Coil64 is inductance coil calculator, that allows to calculate the single-layer and multi-layer air core inductors, the ferrite core inductors or chokes, planar coils on PCB etc.
