5G radio interface: development timeline Today

Millimeter Wave A new radio interface for 5G



mmWave: the bandwidth

• Industry attention for exclusive licensing

• Need to deal with incumbents (e.g. FSS)

• Industry attention on 60 GHz upper part & E-band

• All options on the table for spectrum licensing

• Global harmonization possible

Abundant Millimeter Wave Spectrum can provide fiber-like capacity (multi-Gbps data rates)


mmWave: the range

1 dB/km @70 GHz

Water Vapor

Oxygen

20 dB free space path loss attenuation compared to below < 6 GHz + additional gaseous (Water Vapor / Oxygen) attenuation Inherently short range

Enables X factor of densification

Few Kilometers in outdoor LOS

Few meters in indoor NLOS

mmWave: the beam

2-3 degrees beam width array of antennas for wide angular coverage & multiple simultaneous beams/links @low interference Enables high

multiplexing gain

Electronically steerable phased array antennas to enable dynamic (re)configuration for guaranteed link reliability (in particular in mobile scenarios)

Small form factor (thanks to small antenna aperture and short inter-antenna distance) enabling the support of large number of antennas at the TX and RX


mmWave: the capacity

(20 x 10 x 5) = 1000x capacity increase

Wide contiguous bandwidth

mmWave: the backhaul

• System-oriented approach to develop future

small cell platform

• Wireless backhaul is an enabler

• Extend to cloud based management, edge

caching and other services

• Low Cost & High Capacity

• Leverage high volume WiGig baseband

• Phased Array steerability reduces installation

cost

• > 1 Gbps over 150m+

• Scalable system for outdoor small cell

deployment

• New sites can be added without having

to re-align antenna pointing at old sites

• 1Gbps per channel links provide ample near

term capacity, with future expansion to all four

2GHz unlicensed channels

Few Takeaways



•5G radio interface will need to respond to very challenging and diverse requirements, and is therefore expected to include 2 or more complementary technologies (< and > 6 GHz).

•5G mmW spectrum will include more than one band (e.g. LMDS, V, E bands) with both licensed and unlicensed regimes.

•5G mmW technologies will cover both segments of the small cell network, namely the backhaul and access.

•There is still room for lot of innovations in particular for the mobile access and its joint optimization with the backhaul.
