Until now, cellular networks have never used frequencies above 6GHz. Several higher bands, including ones around 24-27GHz, 38GHz, and 70GHz as well as 28GHz, have more available bandwidth than today’s lower frequency cellular bands. That means more capacity, so more devices can get faster service. The principles used in developing the new ICs can be applied to other millimeter-wave frequencies, Valdes-Garcia said.
The technology is being announced on Tuesday at the International Solid State Circuits Conference in San Francisco. The 28GHz packages are expected to be used in base stations that will go through trials later this year. Large-scale commercial deployment of 5G networks isn’t expected until 2020.
