Why is mmWave crucial for Multi Gbps speeds

A few months back Fudzilla reported about a 5G reference design of the phone with three mmWave antenna openings, and today, Qualcomm announced the new design with four antennas at half the size. Nick covered this part well, but we wanted to add some additional information about this important step in the development of 5G.

Qualcomm claims the word’s first fully integrated 5G NR (New Radio) millimeter wave (mmWave) and sub-6 GHz RF modules for smartphones and other mobile devices. The Qualcomm QTM052 mmWave antenna module family and the QPM56xx sub-6 GHz RF module family pair with the Snapdragon X50 5G modem to deliver modem-to-antenna capabilities across several spectrum bands, in a very compact footprint that is suited for integration in mobile devices.
mmWave crucial for fast 5G

It is very important to underline how hard is it to do millimeter waves as you need these frequencies to get to really interesting speeds. Qualcomm already demonstrated that 4.51 Gbps is possible with the help of 28 GHz mm waves, but of course many were sceptical about the limitations of these high frequencies in the phone form factor. It is one thing to get the speed in the lab and second is to recreate this in urban environment.
