New frontier of mobile broadband — mobilizing mmWave
Sub-6 GHz(e.g., 3.5 GHz)
6 GHz 24 GHz 100 GHz
Increased capacityWith dense spatial reuse
Multi-Gbps data ratesWith large bandwidths (100s of MHz)
Vast amount of bandwidth that is ~25x more than what’s being used for 3G/4G today
Millimeter wave (mmWave)(e.g., 24.25-27.5 GHz, 27.5-29.5 GHz)
Lower latencyWith shorter slot duration (e.g., 125µs), bringing new opportunities

Completed three mmWave auctions so far, including 24, 28, 37, 39, and 47 GHz
28 GHz auction completed in Jun. 2018; each operator assigned 800 MHz; plan to secure additional spectrum in 2021
Assigned 28 GHz mmWave spectrum in Apr. 2019; technical rules for additional spectrum (e.g., 26.6-27 GHz and 39.5-43.5 GHz planned for 2021
Auction completed in Feb. 2020 with a total of 1.6 GHz in 28 GHz band awarded to 4 operators
5G spectrum auction completed in Sep. 2018 with right of use starting January 1st, 2019
26 GHz auction completed in Q4 2018 to enable 2019+ commercial deployments
26 GHz spectrum award planned for Q4 2020
Finland, UK have also made mmWave spectrum available

We are overcoming the mobile mmWave challengeProving the skeptics wrong who said that mmWave could never be used for mobile
1 LOS: Line of sight, NLOS: Non-line-of-sight
Limited coverage and too costly
Significant path loss means coverage limited to just a
few hundred feet, thus requiring too many base stations
Significant coverage with co-siting
Analog beamforming w/ narrow beam width to overcome path
loss. Comprehensive system simulations reusing existing sites.
Works only line-of-sight (LOS)1
Blockage from hand, body, walls, foliage, rain etc.
severely limits signal propagation
Operating in LOS and NLOS1
Pioneered advanced beamforming, beam tracking leveraging
path diversity and reflections.
Only viable for fixed use
As proven commercial mmWave deployments are for
wireless backhauls and satellites
Supporting robust mobility
Robustness and handoff with adaptive beam steering and
switching to overcome blockage from hand, head, body, foliage.
Requiring large formfactor
mmWave is intrinsically more power hungry due to wider
bandwidth with thermal challenges in small formfactor
Commercializing smartphone
Announced modem, RF, and antenna products to meet
formfactor and thermal constraints, plus device innovations.
