TopMachine-To-Machine Communication Infrastructure
M2M communication is broadly uses wireless communication technologies, both licensed and license exempt spectrum bands, short-range wireless communication technologies, and cellular system. M2M communications system over cellular network is already deployed and perhaps will become the longest consumer of wireless bandwidth in the future.
Key Terms in this Chapter
Machine to Machine (M2M): Any technology that enables networked devices to exchange information and perform actions without human’s interaction.
Wi-Fi: A wireless networking technology that uses radio waves in the 2.4 GHz and 5 GHz bands to provide wireless high-speed Internet and network connections. Wi-Fi is a trademark name,that represents a type of wireless local area network (LAN) protocol based on the 802.11 IEEE network standard.
Smart Grid: A modernized electrical grid used to supply electricity to consumers via two-way digital communication in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.
Green Energy: Energy production from sources that are renewable, and are environmentally friendly compared to fossil fuels like coal, oil and natural gas. Wind, solar, and ocean waves are examples of green energy.
ZigBee: A wireless protocol based on IEEE 802.15.4 standard for low data rate networks. With a maximum speed of 250 Kbps at 2.4 GHz, ZigBee is a specification for wireless personal area networks (WPANs), but it designed for low power, so, the transmission range is roughly 50 meters.
Telematics: A term refer to automation in automobiles includes but is not limited to Global Positioning System technology integrated with computers and mobile communications technology in automotive navigation systems.
RFID: A wireless data collection technology that uses electronic tags for storing data, for the purposes of automatically identifying and tracking tags attached to objects. RFID tags do not require line of sight, and may be embedded in the tracked object.
