6CHAPTER 1: PREPARATION
The completion of the RF Site Survey Requirements document is a coordinated effort between the site survey team and the customer management team.
The RF Site Survey Requirements document does not identify potential installation constraints within the customer site, nor does it recommend AP and antenna placement location. The RF Site Survey Requirements document represents a preliminary overview of the customer site, and is used as a baseline for refining site survey requirements.
Environmental The site survey team selects trial AirConnect component installation areas away Considerations from transformers,
refrigerators, and other industrial equipment. Areas with excessive moisture, heat, and dust are inappropriate for installing an AirConnect wireless network.
Signal loss can occur when metal, concrete, walls, or floors block AP transmission areas. AirConnect AP antennas are
The positioning of an AP depends on the floor plan of the site. The site survey team makes AP placement recommendations based on the following installation site variables:
■Indoor installation site
■Large or small proposed radio coverage area
■Wide or narrow proposed coverage area
■Open coverage area or area with documented obstructions
on different channels require careful survey area testing to ensure that radio transmissions do not interface.
Antenna Placement Radio coverage requirements relate directly to installation site constraints. With an
Considerationsomnidirectional antenna, the radio range of the AP (transmitting at 1Mbps) could have a radius up to 1000 feet (303 meters) in open areas. However, in office or retail environments, obstructions can reduce the coverage to a radius of 180 to 250 feet (54 to 76 meters). The coverage area is also referred to as a cell.
The final location of AP antennas is critical to the successful operation of the system. When conducting the survey, consider the exact conditions in the installation area. These conditions include all losses due to cabling and connectors.
