Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields

It is vital to ensure that the emission levels of RFID equipment are measured to ensure compliance with FCC and FDA regulations and in particular with CFR 47 which regulates the Maximum Permissible Exposure (MPE) limits for human exposure to Radio Frequency Electromagnetic fields.

Magellan Technology wishes to endorse, most strongly, the requirement to include MPE limit compliance in all considerations of RFID platforms and standards. This paper seeks to explain why MPE limit compliance is not only necessary but vital to the RFID industry and to customers who rely on the RFID industry to provide safe and not harmful equipment.

The Technical aspects that support the PJM HF Unique 100% Reliability Level

PJM HF achieves 100% reliability whereas UHF only achieves reliability levels of between 85% and 92%. The reasons for the unique reliability of PJM HF are explained below.
Unlike its competitors, Magellan's PJM HF technology offers 100% reliability. This is particularly important as PJM HF technology is used in medical applications, where anything less than 100% reliability is unacceptable.

There are two principle causes of less than 100% reliability:

  • Tags not being read and;
  • Tags being incorrectly read (false reads or ghost tags)

This paper will consider these two causes of unreliability and the means by which Magellan's PJM HF technology avoids them.

Comparison between LF and HF

This White Paper will compare the old LF and the new HF systems by describing their respective functionality in terms of their ability to read multiple tags; their anti collision capability; their stackability; communication speed; memory size; security features; international acceptance; general utility; and cost.

PJM Technology 

PJM stands for Phase Jitter Modulation... This new system is specified in ISO/IEC 18000-3 Mode 2 and provides for very fast data rates that are as much as 100 - 400 times faster than other RFID data rates. In fact the data rate of PJM Mode 2 at 13.56 MHz HF is demonstrably many times faster than the data rates of other HF technologies and indeed UHF technologies.
