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 Metering, Billing/CRM Asia 2013, 22-23 May, Bangkok, Thailand
