This part of ISO/IEC 15149 specifies the physical layer and media access control layer protocols ofwireless network over a magnetic field in a low frequency band (~300 KHz) for wireless communicationin harsh environment (i.e., around metal, underwater, underground, etc.).The physical layer protocol is designed for the following scope:— low carrier frequency for large magnetic field area and reliable communication in harsh environment;— simple and robust modulation for a low implementation cost and error performance;— variable coding and bandwidth for a link adaptation.The media access control layer protocol is designed for the following scope:— simple and efficient network topology for low power consumption;— variable superframe structure for compact and efficient data transmission;— dynamic address assignment for small packet size and efficient address management.This part of ISO/IEC 15149 supports several Kbps data transmission in wireless network within adistance of several meters. It can be applied to various services such as the following areas:— environmental industry to manage pollution levels in soil and water using wireless underground orunderwater sensors;— construction industry to monitor the integrity of buildings and bridges using wireless, innercorrosionsensors;— consumer-electronics industry to detect food spoilage in wet, airtight storage areas and transferthe sensing data from the inside to the outside;— agricultural industry to manage the moisture level as well as mineral status in soil using wireless,buried sensors;— transportation industry to manage road conditions and traffic information using wireless,underground sensors.
