General Compliance and Safety
The usage of radio transmission devices is subject to specific regulatory requirements
governed by regional legislation. In most cases, the specific device must be authorized
for use in a given country and must be installed and adjusted in accordance with specific
radio-frequency settings and in a manner that has been authorized specific to the device
itself in accordance with the specific location of the device. Some users may be
completely or partially restricted from use of the device. Please consult local
governmental agency/agencies for regulatory requirements before use, or contact Exalt or
your Exalt authorized dealer for assistance.
Do not modify this device in any way without the express written consent of Exalt.
Modification voids the manufacturer warranty, and may also be illegal in accordance to
government regulations. In addition, there are no user-serviceable parts or assemblies
inside the product housing. There may also be voltages, signals, and mechanisms within
the device that could be harmful to human safety.
The mounting of this device and associated peripherals and connections (inclusive of
antenna mast, antenna, cabling, egress, lightning protection devices, grounding, power,
and so on) may be subject to regional requirements for health and human safety. A
qualified professional installer and an electrician are highly recommended, and may be
required by law.
Exalt cannot warranty the device or be found liable for any
unauthorized use or installation of the device.

The Exalt i-Series of Digital Microwave Radios
The Exalt i-Series of Digital Microwave Radios are the most advanced carrier-class
point-to-point terrestrial radio communications devices operating in the 2400 to 2483.5
MHz, 4940 to 4990MHz and 5250 to 5850MHz frequency bands, respectively. Figure 1
shows the EX-2.4i Digital Microwave Radio.
Figure 1 EX-2.4i Digital Microwave Radio
The i-Series radios connect voice and/or digital data from one location to another,
obviating the need for copper or fiber connectivity, or enhancing existing connectivity by
providing a redundancy solution, a primary solution, and/or additional capacity.

Note: Not all software features mentioned in this document are
enabled on all radios with the current firmware releases. Please note the
revision history in the front section of the manual and check the Exalt
website download section to verify the most recent firmware release
available for your product.
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.
The EX-4.9i utilizes frequencies in the 4940-4990MHz range, and is typically a licensed
band reserved for use by Public Safety agencies and applications. This band is not
generally available outside of North America.
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 authorized Exalt
representative for information pertaining to your country.
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.
Basic Features
The i-Series Digital Microwave Radios are single integrated units intended for all-indoor
or enclosure-based mounting. The associated antenna is typically mounted on a tower or
rooftop mast structure with RF cabling running from the antenna location, with an egress
through the structure or enclosure, with proper lightning suppression and grounding, to
the RF connector of the radio. In turn, the communications interfaces and power
connections are directly applied to the radio, or in some cases, also with an egress
through the structure or radio enclosure with proper lightning or surge-suppression
devices and associated grounding.
