Citywide M2M Applications
• M2M have many applications with different requirements• Millions M2M devices in a citywide network
– Utilities Smart Metering– Utilities Smart Grid– Fleet Management– Automotive Telemetrics– Property security– Short Range Telemetry– Long Range Telemetry– Video Surveillance– Machine Operation and Control

Service Characteristics
• Traffic- amount of data exchanged over a time period, defined as tonnage (Bytes per hour)
• Availability- percentage of time that service is available (%)
• Latency- communication delay
• Reliability- equipment failure rate (#/time)
• Cost- investment, operation and maintenance

M2M Application Requirements• Low traffic, large latency, regular reliability, regular availability,
Low cost, high volume (millions)– Smart metering– Fleet management– Automotive telematics– Property security
• Low traffic, low latency, high reliability, regular availability, Medium cost, small volume (thousands)– Smart grid– Long Range Telemetry
• High traffic, regular latency, regular reliability, regular availability, High cost, low volume (hundreds)– Video surveillance– Short Range Telemetry
• High traffic , low latency, high reliability, high availability, Very high cost, very low volume (tens)– Machine operation and control
