i-Bean Network Hardware
Performance Considerations
Since the i-Bean wireless network uses radio waves to communicate between devices, there are
a number of items that need to be considered when implementing this type of network. This
section of the manual provides a number of suggestions that will ensure that your wireless
network will operate at its peak level of performance.
General Installation Recommendations
When installing the i-Bean wireless network devices, observe the following recommendations
when possible for optimal performance:
• Higher locations for i-Bean devices are generally better than lower locations. A
higher location usually provides a clear communication path over obstacles.
• Locate i-Bean devices at least one foot from metal shielding on all sides. Avoid
obstacles such as book shelves and file cabinets.
• Avoid sources of electrical noise, such as motors, pumps, and welding machines.
Locate i-Bean devices at least two feet from fluorescent fixtures.
• Avoid other devices using 900 MHz Industrial/Scientific/Medical (ISM) band. This
includes such items as cordless phones, intercoms, and walkie-talkies.
Warning
These electronic products are sensitive to electrostatic discharge (ESD).
Permanent damage to these devices can result if subjected to high energy
electrostatic discharges.
Proper precautions are recommended to avoid performance degradation or loss
of functionality.
Note:
For instructions on installing the i-Bean devices, refer to the Quick Start Guide for
Building Automation (P/N DOC-0010).
