5. Why do we Need 4G for the Rural SmartGrid WAN? WiMAX today, LTE tomorrow 5 - 8 miles coverage 25-45 Mbps capacity Flat All-IP network Low Latency Utility applications that demand sub 100ms latency Real-time consumption measurement by the utility call center QoS Allow real-time activation of critical DA devices Voice & Data applications Mobility Line truck crews connectivity to Smart Grid applications

6. 4G Wireless Architecture for Rural Smart Grid

7. Platform options Carrier-class WiMAX 802.16e certified platform Wide range of frequencies (2.X GHz, 3.X GHz…) Data, Voice and Video – Fixed & Mobile Security: AES128, NERC-CIP Deployment options Macro and all-outdoor Micro BST Outdoor remote RF heads Scalable platform with up to 6 sectors Coverage & Capacity Optimized air link coverage and capacity 2 nd /4 th order diversity, MIMO and Beamforming Performance <100MSec roundtrip configuration QoS levels for different applications 4G Requirements for Rural Smart Grid Key Attributes

8. Private 4G vs. Commercial Infrastructure Why Private Networks for Rural Smart Grid Commercial Operators can’t guarantee QoS Commercial Operators provide limited Coverage SPG is Mission Critical not Commercial Ability to add applications- Not a point fix solution “ …in the future, most utilities will rely as much, if not more, on private, internal networks that can be built and maintained to their standards” [UTC Report January 2009]

9. Business Case Analysis for 4G Rural Smart Grid Use business case tools to analyze and understand the key technology and financial trade offs for an rural utility’s particular deployment needs Examine trade offs for network deployment approach; build your own network vs. partner with existing operator Analyze technical deployment issues; cost differences with manufacturers, different architecture approaches, impact of additional services Analyze financial trade offs; understand payback scenarios, maximize returns Case studies using the WiROI business case tool Dashboard GUI for Sensitivity Analysis and “What If” Scenarios to maximize a rural smart grid deployment The WiROI™ Tool demo is available free at: www.wireless2020.com

10. Comparison Build your Own Network vs, Lease From Broadband Wireless Operator Example of Large Rural Deployment; estimate 40K sq km of coverage area Total Cost over 10 Years Lease Option- $203M Build Option- $154M Build Option requires CapEx to complete the network in first two years Lease Option requires higher OpEx continuing through out 10 year period Payback crossover estimate Year 5-6. Additional Benefits for owning network Coverage where it is needed Other internal and external service when network is in place Communication network for distribution automation and demand response Service vehicle broadband communication Long term value of network asset
