Implementing Microwave Networks in Electric UtilitiesFROM TDM TO IP
Microwave Networks – Practical Considerations for Electric Utilities• First Wave Implementation – 1940s to 1960’s – Experimental Voice Grade Circuits
on low capacity 950 and 2 GHz analog baseband
• Second Wave – 1970’s to late 1980’s – low to medium capacity analog baseband systems – still voice grade channels and specialized baseband relaying channel for breaker protection on high voltage systems. Voice applications secondary and not critical
• Third Wave – 1990s to 2008 – Digital Microwave, Conversion from analog. Migration from 2 GHz to 6 GHz for cellular space. T1 and Sonet OC1 and OC3 heavily implemented.
• Fourth Wave – Mid 2000’s to present day – Conversion from T1 and SONET to IP based systems. From Layer 2 to Layer 3 transport, OSPF and MPLS are primary conversions taking place now.

TYPICAL SUBSTATIONSCADA , Relaying and Metering
System Control and Data Acquisition
Perimeter Security systems
Data needs are low less than 0.2 Mbps are typical high side (excluding Video)

DESIGN CONSIDERATIONS – ELECTRICAL UTILITIES
Small Municipalities and Small Electric Coops
- May have smaller needs and budgets
- Or may be required to have high reliability telecommunications networks….
- Distribution Coops
- Transmission Coops
- Generation Coops
- Power Agencies
- Investor Owned Utilities
PLANNING ISSUES
Does the organization/coop have staff to do the SCADA and Telecom Network work?
Some want a contractor to furnish everything
Some want project assistance and then hand off to their internal staff
Many smaller organizations simply do not know how to do planning, design, implementation, and maintenance.
Who is the decision maker or influences the decision makers?
APPROACHES TO CONSIDER
Potential clients are not the same from coop to coop.
- Some will only buy equipment, some will buy an entire network with maintenance
Needs assessment
- You may need to define scope and develop planning for the coop, then do the rest…
- - or some may have partially developed designs and want you to take over
How to approach the network
- Learn about the coop, each one is different in organization and sometimes in functions
- Discover how to become a valuable and reliable partner. It is almost never about lowest cost, but highest value.
