From radios to core networks, a consensus is forming that 6G needs to offer more focused technology than 5G, or is it more technology? Energy, spectrum, and AI top the list of what 6G needs. EE World spoke with four engineers who attended the March 3GPP meeting in Korea. Here’s what they had to say. If you ask people, “Has 5G been successful?” you get different answers depending on who you ask.

This passive device lets you steer signal beams for over-the-air wireless test systems. Vaunix Technology, a manufacturer of modular RF/wireless test equipment, has introduced the LBM-7250-4 Lab Brick Butler Matrix, a beamforming tool that works with phased-array antennas to steer beams between transmitters and receivers. The Butler Matrix has four passive inputs and four outputs and can be used for testing both transmitters and receivers.

The MS1130 and MS1150 oscillators from Mixed-Signal Devices use digital architecture to produce low-noise, low-jitter clock signals. Mixed Signal Devices (MSD) has introduced two clock generators designed for synchronizing signals in datacenters, telecom networks, and other digital communications systems. The MS1130 (10 MHz to 1 GHz) and MS1150 (20 MHz to 2 GHz) use a digital architecture that MSD’s Avi Madisetti claims produce low noise clocks.
