Detailed performance measurements are usually not required for pre-installation, but they can
typically be easily performed at this stage and may be helpful for later troubleshooting efforts or
for internal records. During troubleshooting, there may often be a point at which a back-to-back
bench test should be performed to re-verify many or all of the items above, and in the case of a
suspected faulty device to help confirm the fault, and determine which end of the system is at
fault and in need of repair/replacement.
Detailed instructions for back-to-back bench testing are included in Appendix B.
2.3 RF Output Power Setting
The maximum RF output power is bounded by one of the following criteria:
• Maximum RF output power setting capability of the radio device
• Maximum RF output power allowed/authorized by the local government regulations and
for this specific device
• Maximum EIRP (effective isotropic radiated power) of the transmission system
allowed/authorized by the local government regulations and for this specific device
• Desired RSL to not exceed the maximum RSL allowed by the device
• Desired RSL to minimize/eliminate interference into neighboring systems
In many cases, the radio must be pre-configured for legal maximum output power
before connecting to the antenna and transmission system. Instructions for
adjusting the output power can be found in this section (below) and in section 5.7.
The following information pertains to specific regulatory requirements based on up-to-date
information for countries where the EX-5r is authorized. A list of recommended antennas can be
found in section 4.3.
2.3.1 United States
The EX-5r operates under FCC Rule Parts 15.247 and 15.407 as a license-exempt device, and
must be professionally installed. It may only be used as a point-to-point transmission device for
fixed or temporary-fixed (non-mobile) installations. The device is subject to the following
restrictions:
• External amplifiers may not be used to boost the power, or to overcome transmission
system losses, unless the specific amplifier/cable/antenna combination has expressly been
authorized by the FCC. The output power must never exceed +24dBm.
• Cross-border transmissions are expressly prohibited, except with written permission from
both the FCC and the governing body of the neighboring country (Cofetel for Mexico,
Industry Canada for Canada).
• Only parabolic dish antennas or directional flat-panel antennas may be used. No other
types of antennas (omni-directional, etc.) are authorized. Parabolic dishes of either grid or
solid type are allowed. Maximum gain of each type of antenna certified is:
o Parabolic Dish: 37.5 dBi (6-foot diameter)
