AZALEA MSR4000 INSTALLATION GUIDE

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 1

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

Site 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 MSR4000 mounting.

Detailed site study

Site survey engineer should conduct detail measurements according to the plan, the

measurements and records include site location information, antenna selection, MSR4000

mounting position etc. Site survey report is suugested to prepared after all site survey works

finished.

¾ Eye 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.

¾ Spectrum measurement (optional): radio environment

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.
