Variables Affecting Performance
Appendix C: Environmental Considerations 99
Variables Affecting Performance
Reader performance may be affected by the following variables, depending on the site
where your Reader is being deployed:
 
Environmental
 
Tag Considerations
 
Multiple Readers
Environmental
Reader performance may be affected by the following environmental conditions:
  Metal surfaces such as desks, filing cabinets, bookshelves, and wastebaskets
may enhance or degrade Reader performance.
 
Antennas should be mounted far away from metal surfaces that may adversely
affect the system performance.
  Devices that operate at 900 MHz, such as cordless phones and wireless LANs,
can degrade Reader performance. The Reader may also adversely affect the
performance of these 900 MHz devices.
 
Moving machinery can interfere the Reader performance. Test Reader
performance with moving machinery turned off.
  Fluorescent lighting fixtures are a source of strong electromagnetic interference
and if possible should be replaced. If fluorescent lights cannot be replaced, then
keep the Reader cables and antennas away from them.
  Coaxial cables leading from the Reader to antennas can be a strong source of
electromagnetic radiation. These cables should be laid flat and not coiled up.
Tag Considerations
There are several variables associated with tags that can affect Reader performance:
 
Application Surface: Some materials, including metal and moisture, interfere with
tag performance. Tags applied to items made from or containing these materials
may not perform as expected.
