performed BEFORE the purchase of this equipment. This document primarily focuses on the
installation and maintenance of the device, assuming that path engineering and site planning has
already been performed. Please refer to Exalt’s document “Exalt Communications: Guidance for
Engineering and Site Planning of Terrestrial Wireless Links” for detailed information on these
activities.
The EX-2.4i utilizes radio frequencies in the range of 2400 to 2483.5MHz. In most countries this
frequency band is 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 users as well as other devices that occupy this spectrum. In these
cases, it is up to the engineering and maintenance personnel to design around existing and future
interference sources, recognizing that there is a chance that the interference conditions could be a
very dynamic condition, 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 must be disengaged or
modified 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, maximum output power, application, limited geography of use, and
other such regulations. The engineer or user is encouraged to determine these limitations and
engineer/install the system within the confines of all local regulations. This guidance is extended
to the peripheral equipment, installation and cabling of the system, which may be regulated for
human safety, electrical code, air-traffic control, and other such entities.
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. Please consult your local
regulatory organization(s) to determine the usage requirements.
In almost all cases, either for license-exempt or other designation, 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 dealer for information pertaining to your country.
1.2 EX-2.4i Basic Features
The EX-2.4i Digital Microwave Radio is a one-piece radio device that is intended for all-indoor
or radio enclosure-based mounting. The associated antenna is typically mounted on a tower or
mast structure on a rooftop, with RF cabling running from the antenna location, with an egress
through the structure or radio enclosure, with proper lightning suppression and grounding, to the
