The company on Monday unveiled its new QTM052 millimeter wave and QPM56xx sub-6GHz radio frequency antenna module families. They work alongside Qualcomm's Snapdragon X50 5G to bring superfast network speeds to smartphones. The modules will let phone makers cover the gamut of 5G airwaves, including the shorter range but faster millimeter wave spectrum and the more reliable but slower sub-6GHz airwaves.

The modules will show up in mobile hotspots later this year and smartphones in the first half of 2019. The potential peak download speed could be up to 5Gbps for the millimeter wave variant, though the more realistic speed you'll see in phones is closer to 1.4Gbps, Qualcomm said. That's much faster than today's 4G, which is about 70Mbps, and even faster than the sub-6Ghz's expected speeds of 400Mbps to 500Mbps, the company noted.
