Telecommunications Strategy
 Use internal network infrastructure – pilot cables, fibre optics
– Fibre optics network for backbone traffic – SDH, DWDM
– IP MPLS data network for data
– Separate network for critical real time applications – teleprotection,
PMU, IEC61850, SCADA
 Build & Operate private access network
– AMI Network
• RF Mesh for dispersed residences/premises
• PLC for dense residences/apartments/condominiums
– DA Network
• Licensed/Unlicensed wireless network




Use public network when internal networks unavailable
Use single integrated network for AMI, SCADA, DA etc
Monitor/manage network 24X7 from NOC
Outsource operations/maintenance

Wireless Network: Public vs Private
•
•
•
•
Public Network
No SLG/SLA
Unreliable for control applications
Designed for mass public requirements
Catered for mobile communications, broadband, social networking,
internet access, gaming etc
• Unsuitable for legacy low bandwidth services
• Cost effective for small deployment
• Utilities tied down with telco technology lifecycle
Licensed Wireless Network
• Higher reliability
• Suitable for control applications
• Designed for utility legacy and low bandwidth applications
• Cost effective for large deployment
• Longer life cycle
• Frequency and license availability and constraints
Private Network
License Free Wireless Network
• Cost effective solution
• Self healing technology
• Suitable for non control applications
• Subject to interference
