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.
