Exalt EX-5r (integrated antenna model)
Generally, the r-Series requires 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-5r utilizes 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.
