Why do we Need 4G Network?• 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• Location awareness

Private 4G vs. Commercial Infrastructure

Why Private Networks for 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”
