“The mobile wireless industry requires low, mid and high band spectrum for 5G to reach its full potential. MmWave technology is important to the progress of 5G networks, granting faster data speeds and much higher capacity compared to 4G LTE.”
Chris Pearson
President, 5G Americas

“Once considered impossible to use for mobile wireless communications, mmWave now is an opportunity to utilize massive amounts of spectrum for extreme capacity, high throughput and ultra low latency for services on devices beyond just smartphones and laptops.”
Lola Awoniyi-Oteri, engineer, principal, of Qualcomm Technologies, Inc.
