The ExtendAir
®
(TDD) Series Direct Mount radios 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 has already been performed.
The 240xx family ExtendAir
®
(TDD) Series Direct Mount radios utilize radio frequencies in the 24.05
to 24.25 GHz range. In most countries these frequency bands are considered as ‘license-exempt’ or
‘unlicensed.’ This means that virtually any user may use these frequencies freely, without paying for
access, or any type of prenotification, post-notification or registration. As a result of this designation,
users may also move or change these systems at any time, with significant flexibility to the location,
orientation and configuration of the system. However, due also to this designation, there may be
uncontrolled interference from other similar devices that occupy this spectrum. In these cases, it is up
to engineering and maintenance personnel to design the system with existing and future interference
sources in mind, recognizing that there is a chance that the interference conditions could be very
dynamic, and outages may occur on the system as a result, and that, in some very rare cases, the system
may cause interference into another system and may be required to be disengaged or modified/re-
oriented to eliminate the interference.
If the spectrum in your country is designated as ‘license-exempt’ or similar, this does not infer that the
installer may configure the system in any manner at any location. In most cases, there are regulations,
or device-based conditions that limit the use of the device, such as maximum gain antenna, antenna
types 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 certain countries, the spectrum for this product is NOT considered to be license-exempt. In these
cases, there may be additional regulatory requirements concerning the location, frequency, power,
orientation, configuration, and other aspects of the system, including, in some cases, a need for link
Note: All models offer license key upgrades for 128 or 256-bit AES encryption.
