DSL router uses parts from old phones
A consortium of companies found a clever way to recycle phone parts, showing how reusing electronics can improve sustainability. Electronic waste is a huge environmental problem of which disposed cell phones are a major contributor. Think about it, all that metal, plastic, and working semiconductors go into landfills. Some materials, such as gold from PCB…
FAQ on the Butler matrix for beamforming: part 1
This passive beamforming topology is not well known but is widely used — a common situation in the RF world. For many years, radar applications defined much of the world of directional antennas. These antennas were designed with a fixed directivity or rotated in a steady pattern at a known rate, as seen in Figure…
Standards group to address 6G multiple access
ETSI has established a new Industry Specification Group (ISG) focused on Multiple Access Techniques (MAT) for 6G mobile systems.
