The ExtendAir G2 24GHz model number scheme uses the first two digits to define the general
frequency band (in GHz) and the last three digits to define the connector and base configuration.
• ExtendAir G2 models have one 10/100/1000BaseT PoE port and one additional
10/100/1000BaseT port (see Figure 5
)
– configured with 25Mbps of full-duplex Ethernet capacity
The ExtendAir G2 24GHz models require a clear line-of-sight and proper path clearance to achieve a
high-performance, reliable connection. Perform professional path engineering and site planning before
installing this equipment.
The primary focus of this document is the installation and maintenance of the digital microwave radio,
and assumes that path engineering and site planning were already performed.
The ExtendAir G2 24GHz radios utilize radio frequencies that are considered ‘unlicensed’ in most
countries. This means that the frequency plans and radio configuration are not coordinated with other
users of the spectrum. Also, the frequency, channel-center frequencies, occupied bandwidth, and the
Transmitter-to-Receiver frequency separation (also known as T/R spacing) are utilized to allow
maximum use of the 24 GHz unlicensed band. In many bands, it is necessary to offer unique part
numbers to allow coverage of a 'sub-band' of the entire frequency band, and also to address the specific
T/R spacing that is required. The following is a table of the configurations supported.
In most cases, there are regulations or device-based conditions that limit the use of the device, such as
minimum or maximum antenna gain, antenna polarization, and maximum output power, as well as, in
some cases, application limits, limited geography of use, and other unique regulations. The link
design engineer and/or professional installer must determine these limitations and engineer/
install the system within the confines of all local regulations. Also, it is required to examine any
regulations that may apply to peripheral equipment, installation and cabling of the system that may be
regulated for human safety, electrical code, air-traffic control, and other safety-related categories. In
some cases, a need for link registration, coordination, and fees that may apply to the system usage.
Please consult your local regulatory organization(s) to determine usage requirements.
In almost all cases, the product itself must be authorized for use in your country. Either Exalt or Exalt’s
agent must have applied for certification or authorization to allow the sale and deployment of the
system within the country. It is also possible that only certain versions or configurations of the device
are allowed within a particular country. Please contact Exalt or your authorized Exalt representative
for information pertaining to your country.
Basic Features
The ExtendAir G2 24GHz Digital Microwave Radios are intended for all-outdoor mounting and
designed to be used with an indoor-mounted power injector.
For most implementations, the entire unit is typically mounted on a tower or rooftop mast structure,
with Ethernet/Power and other optional interface cables running from the unit location, through a
structure penetration, and to the power injector and connected communications equipment.

Note: It is the professional installer’s responsibility to ensure that the radio system is
implemented in a legal fashion. Exalt is not liable for any unsafe or illegal installations.
