Introduction
• Communicate among machines, sensors, devices or “things”
• Over wired or wireless communication network • No human intervention whilst devices are
communicating end-to-end
Motivation
• Efficiency & Productivity• Mature Technology
• Wireless Communication (e.g. 4G)• Rise of Cloud
• Lower cost• Electronic devices • Connectivity
• Regulatory Mandates

Communication - Data Transmission
Access Network • Wired Solution - dedicated cabling between sensor and gateway
(E.G. cable, xDSL, PLC, optical, etc.)• Wireless Capillary Solution - short-range link
(E.G. Wi-Fi, RFID, Bluetooth, WLAN, ZigBee, etc.)• Wireless Cellular Solution - cellular link
(E.G. GSM, GPRS, EDGE, 3G, LTE-M, WiMAX, etc.)

Communication - Data Transmission
Gateway • Connect access and core networks• Network address translation• Packet fragmentation/defragmentation
Core Network • Connect to computer system• IPv6-enabled Internet
Management - Data Analysis
Data Assessment • Enterprise software application• Standalone system
Response• Automate a business process by automating the flow of data• Right data, right place, and right way
Example:• Data Normalization - Extract data and convert into standard format• Rules Engine - Apply rules to data for modelling• Device intelligence - Add intelligence to device for control
Cloud – Scalability, Flexibility & Security

M2M is in a growing trend...
Connections• Global M2M connections reached 195 million in 2013,
growing at almost 40% per year (38% CAGR) • M2M connections now account for 2.8% of all global
mobile connections, double the 1.4% share recorded in 2010
Device• 12.5 million M2M-capable devices by 2020
Revenue• 23 percent annual growth rate, rising from $121 billion in
annually derived revenue in 2012 to become a $948 billion business by 2020
