Detailed performance measurements are usually not required for pre-installation, but can
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 verify many or all of the above items, 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 or replacement.
Note: See Back-to-back Bench Testing on page 118 for detailed
instructions.
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 effective isotropic radiated power (EIRP) 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
Note: 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 also be found in
System Configuration Page on page 78.
The following information pertains to specific regulatory requirements based on up-to-
date information for countries where these radios are authorized. A list of recommended
antennas is listed in
Antenna/Transmission System on page 57.
United States Compliance
The EX-2.4i and EX-5i families operate under FCC Rule Parts 15.247 and/or 15.407 as a
license-exempt device. The EX-4.9i operates under FCC Rule Part 90 as a licensed
device. All of these devices must be professionally installed. They may only be used as a
point-to-point transmission device for fixed or temporary-fixed (non-mobile)
installations. The devices are subject to the following restrictions:
• Do not use external amplifiers to boost the power or overcome transmission system
losses, unless the specific amplifier/cable/antenna combination has expressly been
authorized by the FCC. The output power must never exceed +30dBm.
• 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).
