3.3 The principle of site survey
1) The principles of site survey of MESH networks are as: Mesh No obstacle in 60%
of the 1st fresnel zone. It will secure LOS in most areas and the coverage capability is
secured and the number of sites could be saved.
2) 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.
3) Interference must be considered in site selection. New site should avoid known
interference, unless the interference is controlable
3.4 Site Survey Guide
Site survey mainly include location selection and detail site study
zSite Selection
The site survey engineer should be experienced with good knowledge of
microwave propagation, antenna ,feeder, 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 required site
data, the site data includes terrain information, end-user distribution and their
behavior, radio environment and the coverage target of MESH networks. Power
availability, line access availability , permit of antenna installation are mandatory
aspects to be considered in site survey. It is suggested to hunt more locations than
actual needs that back-up sites can be used if the availability of some sites changed.
Actual measuremet is suggested done for complex radio environment. The ideal
site should meet following requirement:
minimum obstacles to the target coverage area from the antenna.
Availability of power
Availability of Line access for Gateway
Permit of antenna installation and MSR4K44S mounting.
zDetailed site study
Site survey engineer should conduct detail measurements according to the plan, the
measurements and records include site location information, antenna selection,
MSR4K44S mounting position etc. Site survey report is suugested to prepared after
all site survey works finished.
¾Eye measurement: building information, terrain information
Eye measurement is to verify there are any obstacle and reflection in wave
propagation environment and terrain informing, such as building, trees, etc.
¾Spectrum measurement (optional): radio environment

AZALEA MSR4K44S INSTALLATION GUIDE
COPYRIGHT 2007 AZALEA NETWORKS 15
Spectrum measurement is to get familiar with radio environment in the
target coverage area and antennas. The interference could from Wi-Fi APs
and other systems.
¾Site investgation: the availabity of power, installation of antenna and
MSR4K44S.

4 Antenna Installation
4.1 Principles
zHeight of antenna installation:
¾The antennas height can be different even for antennas connected to same
MSR4K44S. It would be determined by the space of installation, or by design
requirement;
¾The antenna height for access could be 20 meters in open and flat area of city. It
could be 30 meters in open area in rural flat area;
¾Too high antenna installation will decrease the coverage capability close to
antenna, it is much popular when using omni antennas;
¾Too high antenna installation will have another negative impact for system
performance by interference to sites in surrounding areas. Its signal strength will be
seen by many other sites, which is hard to avoid interference.
zAntenna azimuth:
¾The main beam of antenna should point to the most dense traffic area to have
better coverage and link quality;
¾The overlapping coverage between two neighboring site should be less than
10% of its total coverage area in urban scenario;
¾Overlapping area should not be too large in suburban and country area as well,
and the angle of two neighboring antenna main beam should not be less than 90
degree;
¾To avoid over coverage of an antenna, the antenna main beam should not point
to the center of straight streets.
It should notice that the coverage capability changed if the azimuth of antenna
adjusted, to improve coverage in one direction will give negative impact to other
direction. The proper azimuth is very important in network building up stage.
zAntenna down-tilt angle desing:
¾Down-tilt is widely used to have better coverage and less interference to
neighboring sites;
¾The down-tilt angle should be well designed, too high down-tilt will impact
antenna beam form, and have the negative impact of coverage;
¾The design of down-tilt antenna angle should consider the output power,
antenna height, target coverage area, radio environment, etc. It should be done after
site survey.
