A site survey is performed to characterize signal propagation within the building, investigate donor signal options and to determine equipment space and cable routing issues.
The site survey is performed by way of numerous analyses.
A receiver and mapping software is used to record dominant channel/carrier/PN received signal strength for single or multiple wireless service providers at various locations within the building. This helps to determine potential donor sites and repeater requirements. Potential donor signals are also investigated at the roof level, for neutral host opportunities that may not require dedicated base stations.
- Wireless capability to handle high traffic areas such as conference rooms and business centers.
- Spectrum snapshots are taken for each wireless service provider’s bandwidth at all potential donor antenna locations. This is used to identify repeater bandwidth, gain, and power requirements, and pinpoint potential interference issues for early intervention.
- Transmitter tests are used in applicable environments to verify paths in complex inbuilding wireless applications.
- Building materials, configuration, and existing wiring are analyzed to help design a system that requires minimal construction and rewiring, and documentation is done on variations in client RF environments. Equipment that holds potential interference, such as metal racks, concrete walls, etc. are taken into account.
- Building codes and client safety requirements are documented and closely followed, as they are unique to each setting and situation. For example, most hospitals require plenum rated cable to be used rather than standard coaxial cable which significantly affects cost. Common safety features that are followed include cable fire ratings, safety training, safety equipment, and union labor.
- iBwave design is developed to confirm all areas within the site are covered and provided to the client for review and approval.
