2G / 3G Critical requirements
Requirements Details
Differentiation for eachtype of service - QoS
Two classes of services at least:• SCADA (high priority)
• AMM (low priority)
Management • Supervision integration
• Service inventory
• Traffic reports
• Logistic adaptation

Notes
Mobile technology
roadmap
3G coverage will probably reach existing
2G coverage in the next two years
Base Station / Node B
battery autonomy
Require new investment
Minimum bandwidth
guaranteed
Not possible to guarantee
Only a maximum probability in which
bandwidth is less than 4 kbps could beoffered
Differentiation for each
type of service - QoS
Not possible. It should be resolved in
the customer side
Management Covered by new mobile M2M platforms

2G/3G could be used for SG but there is a long way to go
• Regarding mobile technology, 3G will be used where available
•New mobile platforms adapted to M2M provide required managementcapabilities
• Required investment in Base Station / Node B batteries could be high
• There are the following pending issues:
• Prioritization mechanisms in 2G/3G are not adapted to SCADA
requirements
• There are not QoS capabilities
