Chapter 1 Installation materials Survey Description

1.1. About Microwave survey

Microwave includes three type survey, and Installation survey will be described detailed.

1, Installation Materials survey

Installation Materials survey plays a very important role in a project. An accurate, detailed

and valuable survey report not only provides very important basis for correct goods

delivery of Huawei, but also gives important data and reference information for subsequent

engineering design, suite delivery and project construction.

2, Site survey

To establish precise geographic positions (coordinates) and ground elevations of proposed

sites, later used in radio frequency interference(RFI) calculations and frequency

coordination activities;

To determine tower conditions, tower heights, the minimum and maximal available

antenna height, whether there are obstacles or not around the tower;

3, LOS survey (Line Of Sight)

Surveyor performs the survey of microwave transmission paths to accomplish the following

important objectives:

To verify the “free-space” transmission conditions (i.e., sufficient clearances) can satisfy

with the proposed path, Line Of Sight, whether there are obstructions along the path, and

the obstacles heights;

To identify any potential sources of reflections, either on-path or off-path, which could

interfere with normal operation of the radio link;

1.2. Preparations for Survey

1.2.1. Liaison Meeting for survey

Prior to the field verification survey, the PM of Huawei and the surveyors shall have a

meeting together with the customer. The purposes and schedule of the survey should be

defined clearly on this liaison meeting.
