ExtendAir eMIMO Series Digital Microwave Radios

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
Time Division Duplex (TDD) Factors
The ExtendAir eMIMO 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
• Mode (modulation)
• The setting of the above parameters determines the following performance factors:
• Ethernet throughput
• System latency (delay)
The following generalizations can be made with regards to these factors:
• The shorter the link distance, the lower the latency, the higher the throughput
• The higher the bandwidth, the higher the capacity
• The higher the mode, the higher the capacity
Link Orientation and Synchronization (future feature)
Link orientation refers to the Radio A and Radio B placement in your network. Link synchronization
refers to using external or internal timing to coordinate multiple links.
For every link, one end of the radio link must be configured as Radio A, while the other end is
configured as Radio B. In single-link systems, it does not matter which end of the system is mounted at
which end of the link, and there is typically no requirement for any link synchronization.
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.
