The FCC recently announced the end of bidding in the auction of the 600 MHz spectrum and that the results will be released soon. Qualcomm Technologies is ready for the much-awaited deployment of 600 MHz spectrum. We have been involved in the FCC proceedings from the beginning to ensure that the band plan was technically optimal and could be efficiently incorporated into products in a timely and cost effective manner.
This prime, low-band spectrum will bring greater capacity and improved coverage to mobile operators’ networks — important benefits for consumers — but it also comes with new antenna design challenges for OEMs, because it stretches the range of frequencies supported in mobile devices, such as smartphones, to new extremes at the low end of the radio spectrum.
The Qualcomm Snapdragon X20 LTE modem and RF transceiver have been designed with 600 MHz band capability. Our advanced RF Front End (RFFE) technologies, such as dynamic antenna tuning, are designed to minimize the OEM design impact in extending their devices’ frequency range to operate in the 600 MHz band without having to increase antenna size or compromise RF performance. In the evolution towards 5G, dynamic antenna tunability will be critical in accommodating the rapidly expanding frequency range of antennas in mobile devices while minimizing the impact on their form factors.
We are working closely with operators and OEMs to facilitate early launches of 600 MHz-capable 4G multimode/multiband devices, incorporating our industry-leading modem, transceiver, and RFFE technologies as part of our Snapdragon mobile platforms.
