o RF link can connect in both directions
o Traffic can be passed across the link
• Configure connected equipment and cabling
o Test Ethernet (CAT5) cabling, and/or T1/E1/DS3 cabling, any auxiliary connector
cabling and configure all interfaces
o Configure IP settings for configuration and management
o Configure passwords and security modes
o Become familiar with the configuration and management interfaces, including the
web-based GUI interface, the SNMP interface and/or the CLI/Telnet interface.
• Configure radio parameters
o Set output power to engineered or allowed level (see section 2.2)
o Set operating center frequency and dynamic frequency setting (DFS) parameters
o Set occupied bandwidth/capacity/modulation parameters
• Make detailed radio performance measurements
o Measure output power
o Measure receiver threshold
o Confirm error-free performance
Some of the above tests may not be possible or practical within a lab environment, due to the
nature of the remote connectivity of peripheral equipment. But it is a good practice to perform as
much as possible in this environment to minimize field/installation time and troubleshooting
efforts.
Detailed performance measurements are typically 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
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 testing are included in Appendix B.
2.2 RF Output Power Setting
The maximum RF output power is bounded by one of the following criteria (in order from
highest to lowest):
• Maximum RF output power setting 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
