Pre-installation Tasks
This section describes the steps necessary to prepare a site for the installation of the Exalt Digital
Microwave Radio.
Link Engineering and Site Planning
Design all terrestrial wireless links prior to purchase and installation. It is best to engage professional
wireless engineering personnel to determine the viability and requirements for a well-engineered link
to meet the users’ needs for performance and reliability.
The link engineering will determine the following attributes:
• Antenna type/gain at each end of the link
• Antenna mounting height/location for proper path clearance
• Antenna system grounding
• Lightning arrestor type(s), location(s), and grounding
• Radio mounting location and mechanisms
• Radio grounding
• Radio transmitter output power setting
• Anticipated received signal level (RSL) at each end
• Anticipated fade margin and availability performance at each end
• Radio settings for modulation and occupied bandwidth
• Anticipated throughput performance
With respect to radio path and site planning, these radios are generally identical to other microwave
terrestrial wireless systems. Engineering of these systems requires specific knowledge about the
radios, including:
• RF specifications (transmitter output power, receiver threshold, occupied channel bandwidth, and
carrier-to-interference tolerance)
• Regulatory limitations on transmitter output power setting and antenna type/gain
• Noise/interference profile for the intended location (where applicable)
Familiarization with the ExtendAir G2 24GHz Radios
The ExtendAir G2 24GHz radios utilize frequency division duplex (FDD) radio transmission. This
means that the radio transmits on one center frequency in one direction while simultaneously receiving
on a different center frequency in the opposite direction. This provides full-duplex configuration with
equal capacity in both directions and minimal latency.
The radios are configured in Horizontal (TX-H) and Vertical pairs (TX-V), with alternate frequency
settings for Transmit and Receive on the opposite ends of the link. The internal diplexers can be
configured in the field (for example, to change a TX-H to a TX-V configuration) to ease sparing and
re-configuration.
Exalt recommends using the Exalt GUI for radio configuration. This interface requires a computer
with an Ethernet port and web browser software, such as Microsoft Internet Explorer 11.0 or above.
