Installation Manual

3-6 Installation
MK-MAN-01 CarrierWave Digital Radio
• Identify potential buildings by identifying targeted customers (applicable if you’re a service
provider)
• Identify potential links by selecting buildings based on the high probability of line of sight
• Arrange for access with the facility personnel into the buildings, equipment rooms, and
architectural plans to become familiar with the location of all ducts, risers, etc.
3.5.2 Site Evaluation Process
The following steps must be completed to perform a successful site evaluation. Each step in the
process is detailed in the following subparagraphs:
• Ensure RF Safety compliance: Ensure that appropriate warning signs are properly placed and
posted at the equipment site or access entry. For a complete list of warnings, refer the Safety
Precautions listed at the beginning of this manual.
• Ensure Compliance with Laws, Regulations, Codes, and Agreements: Ensure that any
installation performed as a result of the site evaluation is in full compliance with applicable
federal and local laws, regulations, electrical codes, building codes, and fire codes.
• Establish Line of Sight between CarrierWave Digital Radios: The most critical step in
conducting a site evaluation is confirming clear Line of Sight (LOS) between a near
CarrierWave Digital Radio and a far CarrierWave Digital Radio. If LOS does not exist,
another location must be used.
CarrierWave Radios in a link must have a clear view of each other, or “line of sight”.
Binoculars may be used evaluate the path from the desired location of the near CarrierWave
Radio to the desired location of the far CarrierWave Radio.
To confirm Line of Sight:
- Ensure that no obstructions are close to the transmitting/receiving path. Take into
consideration trees, bridges, construction of new buildings, unexpected aerial traffic,
window washing units, etc.
- Ensure that each CarrierWave Digital Radio can be mounted in the position required to
correctly align the CarrierWave Digital Radio with its link partner.
• Determine CarrierWave ODU Mounting Requirements: CarrierWave ODUs can be mounted
on an antenna mast, brick, masonry or wall. Refer to detailed installation sections.
• Determine CarrierWave IDU Installation Location: CarrierWave IDUs can be installed tabletop
or cabinet, wall mount, or rack mount. The site must provide DC power. Refer to detailed
installation sections.
• Document Potential Sources of Colocation Interference: When CarrierWave ODUs are
located on a roof or pole with other transmitters and receivers, an interference analysis may
be required to determine and resolve potential interference issues. The interference analysis
needs to be performed by an RF engineer. The specific information required for each
transmitter and receiver includes the following:
