2.3 The principle of site survey
The principles of site survey of MESH networks are as: Mesh No obstacle in 60% of
the 1
st
fresnel zone. It will secure LOS in most area and the coverage capability is
secured and number of sites could be saved.
1. If no LOS secured, area in NLOS area could be covered as well, but the
distance of coverage and area of coverage are decreased, more sites are
needed to provide coverage for same area than LOS scenario.
2.
Interference must be considered in site suevey and site hunting, site
location should be the place in low interference area to have good quality.
Channel planning could help to avoid interference of narrow band.
2.4 Site Survey
Site survey mainly include site location selection and detail site informaton
recording for selection of antenna and installation material design.
1.1.4 Site location selection
The site survey engineer should be very experienced and certified by Azalea
networks. She/he should have good knowledge of wireless wave propagation,
antenna and antenna near parts, MSR products and experiences in wireless
network deployment.
Site location selection is the most important step of site survey. MESH network
design engineer will do on site analysis of target area and recording all
requirement site data, the site data includes terrain information, end-user
distribution and their behavior, radio environment and the coverage target of
