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.
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, including any software limits
that are applied to the use of integrated or external antennas, based on regulatory limits
• 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
Time Division Duplex (TDD) Factors
The ExtendAir (TDD) Series radios are very dynamic, allowing the installer to optimize and control
the performance of the radio system for the intended application. The following parameters must be
carefully determined during the link engineering phase:
• Link distance
• Bandwidth
• TDD frame size
• Mode (modulation)
• The setting of the above parameters determines the following performance factors:
• Number of supported T1/E1 channels (on applicable models)
• Ethernet throughput
• System latency (delay)
Use the ExaltCalc calculator to determine optimum settings for the above parameters to meet the needs
of your application.
The following generalizations can be made with regards to these factors:
• The shorter the TDD frame size, the lower the latency
Note: See Back-to-back Bench Testing for detailed instructions.
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 at the rear of this guide in the EIRP section for your region.
