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

Exalt Communications Inc.

RF connector of the EX-2.4i. In turn, the communications interfaces and power connections are
directly applied to the EX-2.4i, or in some cases, also with an egress through the structure or
radio enclosure with proper lightning or surge suppression devices and associated grounding.
Figure 1-2: Indoor Radio Mount Interconnection
Figure 1-3: Cabinet Radio Mount Interconnection
For highest performance and reliability, it is advised to minimize the length of RF cable, and
associated transmission system losses between the antenna and the radio’s RF port.
The EX-2.4i provides connection for any of the following data communication interfaces, or a
combination thereof:
•100BaseT Fast Ethernet, up to line-speed (100Mbps full-duplex user Ethernet data rate)
•1-4xT1/E1 interfaces for synchronous voice traffic
•DS-3 interfaces for synchronous voice traffic
The EX-2.4i is powered by a direct DC connection (48V) or by an optional external AC adaptor
(sold separately).

Section 2 – Before Installation
2.0 Link Engineering and Site Planning
Any terrestrial wireless link should be designed prior to purchase and installation. Generally,
professional wireless engineering personnel are engaged to determine the viability and
requirements for a well-engineered link that will meet the user’s needs for reliability.
The reader is referred to the document “Exalt Communications: Guidance for Engineering and
Site Planning of Terrestrial Wireless Links.” This document describes all of the pre-planning and
engineering that is required to determine the following parameters:
•Antenna type/gain at each end of the link
•Antenna mounting height/location for proper path clearance
•Antenna polarization orientation
•RF Cabling type, length, connectors, route and mounting
•Antenna system grounding
•Lightning arrestor type(s), location(s) and grounding
•Radio mounting location and mechanisms
•Radio output power setting
•Radio grounding
•Anticipated Received Signal Level (RSL) at each end
With respect to radio path and site planning, the EX-2.4i is generally identical to any other
microwave terrestrial wireless system. Engineering of these systems may not require significant
specific knowledge about the EX-2.4i itself. The most important parameters being:
•RF specifications (output power, threshold, occupied bandwidth, carrier-to-interference
tolerance)
•Regulatory limitations on output power setting and antenna type/gain
2.1 Laboratory Back-to-Back Test
It is strongly advised to perform a back-to-back test, in a controlled environment, prior to
installation. This will allow you to perform several tasks which can be much more difficult to
perform once the radio link endpoints are distant from one another. Most importantly, a back-to-
back test will provide confidence that the radio link is operational and configured properly prior
to installation, so that if troubleshooting is necessary, the radio hardware and configuration
settings are eliminated from the troubleshooting process.
•Confirm that the radio system is generally operational

oRF link can connect in both directions
oTraffic can be passed across the link
•Configure connected equipment and cabling
oTest Ethernet (CAT5) cabling, and/or T1/E1/DS3 cabling, any auxiliary connector
cabling and configure all interfaces
oConfigure IP settings for configuration and management
oConfigure passwords and security modes
oBecome familiar with the configuration and management interfaces, including the
web-based GUI interface, the SNMP interface and/or the CLI/Telnet interface.
•Configure radio parameters
oSet output power to engineered or allowed level (see section 2.2)
oSet operating center frequency and dynamic frequency setting (DFS) parameters
oSet occupied bandwidth/capacity/modulation parameters
•Make detailed radio performance measurements
oMeasure output power
oMeasure receiver threshold
oConfirm error-free performance
Some of the above tests may not be possible or practical within a lab environment, due to the
nature of the remote connectivity of peripheral equipment. But it is a good practice to perform as
much as possible in this environment to minimize field/installation time and troubleshooting
efforts.
Detailed performance measurements are typically not required for pre-installation, but they can
typically be easily performed at this stage and may be helpful for later troubleshooting efforts or
for internal records. During troubleshooting, there may often be a point at which a back-to-back
test should be performed to re-verify many or all of the items above, and in the case of a
suspected faulty device to help confirm the fault, and determine which end of the system is at
fault and in need of repair/replacement.
Detailed instructions for back-to-back testing are included in Appendix B.
2.2 RF Output Power Setting
The maximum RF output power is bounded by one of the following criteria (in order from
highest to lowest):
•Maximum RF output power setting of the radio device

In many cases, the radio must be pre-configured for legal maximum output power
before connecting to the antenna and transmission system. Instructions for
adjusting the output power can be found in this section (below) and in section 5.
The following information pertains to specific regulatory requirements based on up-to-date
information for countries where the EX-2.4i is authorized. A list of recommended antennas can
be found in section 4.3.
2.2.1 United States
The EX-2.4i operates under FCC Rule Parts 15.247 as a license-exempt device, and must be
professionally installed. It may only be used as a point-to-point transmission device for fixed or
temporary-fixed (non-mobile) installations. The device is subject to the following restrictions:
•External amplifiers may not be used to boost the power, or to overcome transmission
system losses, unless the specific amplifier/cable/antenna combination has expressly been
authorized by the FCC. The output power must never exceed +30dBm.
•Cross-border transmissions are expressly prohibited, except with written permission from
both the FCC and the governing body of the neighboring country (Cofetel for Mexico,
Industry Canada for Canada)
•Only parabolic dish antennas or directional flat-panel antennas may be used. No other
types of antennas (omni-directional, yagi, etc.) are authorized. Parabolic dishes of either
grid or solid type are allowed. Maximum gain of each type of antenna certified is:
oParabolic Dish: 30.3 dBi (6-foot diameter)
oDirectional Flat Panel: 20.5 dBi (~2-foot square)
•Maximum transmit power with respect to FCC (USA) EIRP regulations is determined
with the following equation:
P = 30 - [(G - 6)/3] + L
Where:
P= Maximum output power of radio, in dBm
G= Specified gain of antenna, in dBi, from 2400 to 2483.5 MHz
L= Total transmission system losses of all elements between the radio’s RF
connector and the antenna’s RF connector (all cables, connectors, lightning
suppressors), in dB, as specified or measured between 2400 and 2483.5MHz
The maximum EIRP allowed for this device is 52.2 dBm. The maximum RF output
power is +30dBm.
The professional installer is responsible to assure that RF output power has been properly
adjusted so that it does not exceed the regulatory limit, per these conditions.

2.2.2 Canada
The EX-2.4i operates under RSS-210 of Industry Canada regulations. Operation is subject to the
following conditions, unless express permission is granted by Industry Canada to operate in a
different manner:
•External amplifiers may not be used to boost the power, or to overcome transmission
system losses, unless the specific amplifier/cable/antenna combination has expressly been
authorized by Industry Canada.
•Cross-border transmissions are expressly prohibited, except with written permission from
both Industry Canada and the governing body of the neighboring country (FCC for USA)
•Only parabolic dish antennas or directional flat-panel antennas may be used. No other
types of antennas (omni-directional, yagi, etc.) are authorized. Parabolic dishes of either
grid or solid type are allowed. Maximum gain of each type of antenna allowed is:
oParabolic Dish: 30.3 dBi (6-foot diameter)
oDirectional Flat Panel: 20.5 dBi (~2-foot square)
A complete list of allowed antennas can be found within the Industry Canada regulatory
statement at the front section of this manual.
•Maximum transmit power (Pmax) based on Industry Canada EIRP regulations is
unlimited.

Figure 3-1: Radio Installation Flowchart
3.2 Record Keeping
After installation, it is advised that the following items are recorded for the sake of ongoing
maintenance and any future troubleshooting. A record should be kept for each end of the radio
link. It is advised to store a copy of these records at the radio location, at the opposite end radio
location, and a central record-keeping storage location.
•GPS coordinates for antenna locations at each end
•Antenna heights (AGL) as mounted
•Antenna model numbers, serial numbers and specifications
•Antenna polarization as mounted
•Length/type of primary transmission line
•Model number and serial number of RF lightning arrestor used
•Length/type of secondary transmission line(s)
•Transmitter output power setting as installed
•RSL as measured after antenna alignment
