§  Problem to Solve §  Innovation & Disruption §  Solution Details §  Q&A

Agenda


§  80% traffic indoor §  our focus : delivering precise timing to indoor enterprise 3G/

LTE/LTE-A small cells cost effectively

Market Driver


§  Most small cells being deployed are LTE §  Most small cells being deployed are indoor §  LTE requires very stringent time/phase : 1.5µs §  Phase is required even for LTE FDD because of interference

issues. Any type of coordination leads to phase requirement (eICIC, CoMP, etc)

§  Options • GNSS : indoor hurdles, GNSS & Radio signals & site

survey considerations • NTP : not adequate (only ok for residential) • Macro sniff : not always usable when coverage issue • PTP 1588 : deployment considerations

Problem to Solve


Key Synchronization Requirements §  Small Cells require accurate timing §  Timing is dependent on GNSS

Critical Problems

Challenges for Small Cell Deployment

High Cost of GPS antenna cabling Roof access/rental fees Installation Costs through several floors Operators requesting less devices to deploy and manage – combining functions into single device

Offices with Small Cell

1588 Grandmaster in Server Room

GNSS Antenna


Traditional model - CAPEX & OPEX

CAPEX

§  PTP Grandmaster cost §  GPS Antenna •  Permits •  Space on roof •  Surge / Lightning protection

§  L1 coax cabling •  Amplifiers •  Splitters •  One time installation cost

OPEX §  Power, cooling, cage space §  Roof rental for Antenna §  L1 cable run rental costs §  Monitoring & Management


Problem Statement

• Customers complaining of poor voice coverage in building • Lobby & Meeting Rooms at 5th Floor • 16 Floor of Guest rooms • Other floors are apartments • GPS required • How to get signal to all small cells ?


Creativity and …luck…

Small outdoor patio at 5th floor for GPS Antenna instead of

rooftop

No permit needed as not visible from

public


GNSS Cable issue

Size difference between GPS conduit (white) and Ethernet cable (orange)

Lots of work and cost to bring GPS Cable/Conduit from 5th Floor terrace through building to 5th floor server

cabinet

Most use cases would have to go all the way to rooftop


Other Floors set up

Each floor has 1 small cell Small cell secured in closet, not visible from customers

Each floor has 4 or 5 antennas Antenna visible from public on ceiling next to smoke detector Each antenna connected to floor small cell via coax


In the context of Enterprise Small Cell deployments: How significant are costs for external GPS antenna?

Key message

Innovation Market Disruption

Integrated GNSS Master

Reduce Deployment Costs


IGM-1100i Disruptive Integrated GNSS Master Solution

Deployed Indoors Integration, Form Factor, Cost

Ethernet cable •  No L1 coax cable installation issues

Powered over Ethernet •  Reduces cost •  Widest portfolio of PoE solutions from the inventors of PoE

Plug-N-Play Configuration Common management for GNSS antennae and PoE


Capex Average Comparison

Typical scenario 20 floors

Typical Scenario Integrated GNSS Master Traditional PTP GM # Devices 2 1

Cost of Devices around $2,900 includes GNSS Antenna & Receiver

Around $1,000 + cost of Antenna + Cost of Receiver + Cabling

Deployment Costs associated to GNSS antenna connection

Very Low, similar to Wifi access point

North America : $15K-$25K Europe : $10K-$25K APAC : up to $65K (average, depends on building and geography) Lower Deployment Cost is the key differentiation
