Site Candidate Evaluation
Often Technicians will be very comfortable with either the networking side or the wireless side
of the system, but not usually both. To evaluate a potential install site, a form helps ensure all
aspects of the site have been considered. Information about the site is recorded on the form.
Since each site is unique, the form helps to ensure nothing is taken for granted or assumed about
the installation site for the Ripwave equipment.
A copy of this form may be found in Appendix D. It includes places to capture the logistics of
the site, tower or rooftop mount possibilities, GPS coordinates, type of antenna to be installed,
whether or not an outdoor enclosure is provided, power availability, distance between connection
points, ventilation, a place for drawings from every angle, etc. It is from this information that the
site will be designed, then installed to plan.
Interference Analysis
As part of deploying a Ripwave Base Station, the Field Service Engineer must collect critical
information from the site. The data is provided to the RF Engineering personnel, who can then
evaluate the Radio Frequency (RF) conditions. The RF Engineer analyzes the data for existing
interference from other sources, and takes that into account when creating the coverage
prediction map.
The RF Engineer, in turn, supplies to the Field Service Engineer at the site valuable data
parameters and configuration information unique to each system and each site. In addition to
coverage, though, the interference analysis also helps to predict the quality of service, the power
requirements to get above the noise floor, and other expectations regarding the site.
This study helps Navini and the customer decide which type of system (frequency) and antenna
(panel or omni) will provide the best results. To collect the data the on-site Technician or Field
Engineer performs an Interference Sweep Procedure (Appendix E) and supplies that data to the
RF Engineer(s). Refer to Appendix F for instructions on using the sweep tool.
Site Selected & Designed
After evaluating the potential sites and the coverage prediction, the customer must select the
specific site where the Base Station is to be deployed. The site must be carefully blueprinted to
prepare for equipment ordering and installation. Navini can supply specifications and drawings
to help the customer design the site. Refer to Appendices G, H, I, J, and K for BTS
Specifications, RFS Data Sheets, BTS Outdoor Enclosures Manufacturers, Rectifier/Battery
Backup Manufacturers, and a sample Base Station drawing. Check all regulatory standards (refer
to Chapter 1, Page 8 “Regulatory Information”) prior to installation.
