60GHz Spectrum Opportunities

60GHz is a unique new opportunity

1. 14 GHz and 2.16GHz channels offers unmatched capacity.

2. High oxygen attenuation and narrow beams reduces interference between links making it particularly suited for uncoordinated operation.

3. IEEE 802.11ad, or WiGig, and successor standards enable low cost semiconductors and system solutions.

4. Large spectrum footprint already exists for unlicensed indoor operation, enabling a global market for short range communications.

5. Small device footprint and self-aligning, self-install capability makes 60GHz attractive for fixed wireless access and backhaul.

ISG mWT Kick-Off Plenary MeetingETSI premises, Sophia-Antipolis (France)

▪ Launched @ 09.2014, today consists of >50 members, including Operators, System Vendors, Antenna/Components/Instruments Suppliers & Institutes.

▪ Targets to provide a platform and opportunity for companies, organizations and any other stakeholder involved in the traditional MW (6-42 GHz) and mmWave (50-300 GHz and above) industry chain to facilitate the use of this spectrum for large volume applications, such as mobile backhaul/X-Haul, FWA and any other service benefitting from high-speed wireless transmission.

Evolved approach to spectrum sharing at 60GHz

Mult-layer strategy to manage and suppress interference

Pre-deployment Lidar based network planning

Layer 1 Micro-routing 13 dB41 dB of interference

suppressionLayer 2 Interference cancellation 28 dB

Layer 3 Single frequency network

Layer 4 Cloud based routing and route diversity

Employs machine learning, phased array antennas, multi-antenna signal processing and cloud based SDN

Network Planning: 3D City Analysis with LiDAR

• Fully classified 3D City Data fromLiDAR point cloud

• Identify multiple kinds of streetstructures: Poles, buildings, trees, wires, ground…

Physical layer

1. High gain phased array antennas enable steerable narrow beams

2. Power control, beam forming, null steering reduce interference and improve interference rejection

Packet Switched Beams

Red and blue nodes alternate transmit and receive• Even slots: blue transmits on all

faces, red receives• Odd slots: Red transmits all

faces, blue receives• Eliminates need for Tx/Rx

isolation on a node face• Closest interferer that falls in line

of the beam is 15.5 dB lower (600 m)

• 9.5 dB due to free space• 6 dB due to oxygen

Synchronized topology mitigates interference with adaptive TDMA-TDD structure

Open/R L3 Routing Protocol enables Route Diversity

22

Packets are routed around interfered links• Cloud maintains route integrity and pre-computes

alternate routes• Cubic route diversity for full formed network topology• 60 GHz interference directional, bursty and localized• Oxygen attenuation reduces interference• Client Nodes also benefit with alternate path from

neighboring DN

Open/R Custom L3 Routing protocol for fast failure recovery and low latency in wireless networks• Applies Facebook infrastructure and data center innovation• Combines distributed in-network autonomous functions

with centralized controller logic for computing optimum traffic engineered paths in the cloud

ECC (Europe) Regulations

ETSI (BRAN)• Allow fixed outdoor; increase EIRP

• Remove Listen Before Talk (LBT)

• Minimum antenna gain (20 dBi consistent with WiGig)

CEPT SRD/MG & SE-19• Clarify regulatory frame

• Revise 70-03

• Needs updated Harmonized Standard from ETSI BRAN

Next steps

Our goal is a globally harmonized allocation, authorization and rules

Please let me know what we can do together to help make this a reality
