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.
W A R N I N G !
The M6 and Astra-EX antenna ports may be susceptible to damage from
Electrostatic Discharge (ESD). Equipment failure can result if the antenna or
communication ports are subjected to ESD. Standard ESD precautions should
be taken during installation to avoid static discharge when handling or making
connections to the M6 and Astra-EX reader antenna or communication ports.
Environmental analysis should also be performed to ensure static is not building
up on and around the antennas, possibly causing discharges during operation.
