Note: This manual uses terminology to distinguish the characteristics
of specific radio models. The term standard refers to the EX-2.4i, EX-4.9i
and EX-5i models. The term -16 refers to the EX-2.4i-16 and EX-5i-16
models. When no specific mention is made or the term i-Series is used,
this refers to all models.
Generally, the i-Series 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 has already been
performed. Please refer to the Exalt document, Guidance for Engineering and Site
Planning of Terrestrial Wireless Links, for detailed information on these activities.
The EX-2.4i models utilize radio frequencies in the range of 2400 to 2483.5MHz. The
EX-5i models utilize radio frequencies in the range of 5250 to 5850 MHz. 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 pre-notification, 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 registration, coordination, and fees that may
apply to the system usage. Please consult your local regulatory organization(s) to
determine usage requirements.
