The first 5G compatible smartphones are now a step closer after Qualcomm revealed it has made the world’s first mmWave antennas and sub-6Ghz RF modules available to device manufacturers.

5G networks will use a mixture of spectrum, including the long-range, low-level 700MHz band, the mid-range 3.4GHz band, and high range millimetre Wave (mmWave) spectrum that had previously been considered too challenging for mobile communications.
