3Why do we need 4G for the Middle Mile?
Broadband• Video surveillance application to monitor the Grid
• Instant software upgrades
• Instant data collection for Business Intelligence Analysis
• Support future AMI broadband applications
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
