2. Introduction
Terms
• Next Generation Network
• M2M – Machine to Machine
• IoT – Internet of Things
Current Challenges
• IPv4 Limited addresses – Migration to IPv6
• High power networking
• Lack of standardization
3. M2M Is All About
Helping Humans
M2M Is All About
Real-Time “Big” Data
5. Design considerations
• Power consumption
• Cellular network compliance
• Security and Privacy
• Billing for services
• Troubleshooting and Support
• Lack of standardization
7. Challenges of M2M over Cellular
• Service cost
• Badly behaving applications
• Private address space
• Jamming
• Battery life
8. Advantages of Cellular M2M
• Ubiquitous Coverage
• Mobility & Roaming
• Interference Control
• Service Platforms
Human-to-human (H2H) cellular
• Smaller number of users
• Tolerate delay and jitter
• Charging devices every day
NGN: Full packet communication, All-IP
M2M: full automated machine communication
Machine-to-Machine (M2M) means no human intervention whilst devices are communicating end-to-end
IoT
IPV4 : 32 BIT ~ 4 BILLION
IPV6: 128 BIT ~ SEPTIOLLION 10^24
DEVICES NEED TO BE LOW POWER AS MOST OF THEM WILL NOT BE ACCESIBLE
No standardization on protocols and communication between them.
Wireless Cellular Solution – dedicated cellular link: pros: excellent coverage, mobility, roaming, generally secure, infrastructure cons: expensive operate, not cheap to maintain, not power efficient, delays
Service cost: Overhead is large compared to user plane traffic
• Mobility management
• Billing
• Connection control (e.g. attach and PDP context activation)
Applications:
Badly written M2M Applications can create:
• Congestion
• Superfluous signaling
THE advantage of cellular M2M: Ethernet/WiFi/etc only provides local coverage
Users already familiar with and proven infrastructure
Easier configuration: suitable for short-term deployments
Cellular networks provide today ubiquitous coverage & global connectivity
Mobility and High-Speed Data Transmission
… and, above all, interference can be managed
