This document provides guidance on conducting a radio survey for a GSM network plan. It discusses choosing site locations based on coverage, traffic, cost and feasibility. The site survey aims to obtain accurate wireless propagation data and basic site information. Proper equipment is recommended, including a GPS, compass, test mobile and optional items like telescopes, cameras and drive test equipment. A team of engineers and local support is also needed to perform the thorough survey.

Overview
Site survey is a hard work that need patient and carefulness。 The Engineer must
survey seriously with responsibility. Any doubtful problem must be checked and
survey to get the exact and true data. Only the exact and detailed survey report can
ensure the network plan. The site survey is the base of network plan.

Site survey for network plan
2.1 How to make a choice of site and do the survey
The following is the common rule of survey of new site:
Network engineer must do site survey with the operator. The network plan engineers
give the suggestion of location of new site. The operator takes the responsibility of
negotiation with the owner of land and house. The other engineers take the responsibility
of machine room building, transmission, power and towers.
The network engineer
through the survey, get the information of wireless propagation environment, the traffic
around the site. Get the basic information of the new site. The location of new site can be
chosen through the coverage, traffic, condition of build new site, and cost of new site.
The following is the principle to build new site.
 The new site should locate the ideal location of cellular mesh. The windage of
location can’t be more than one quarter of the coverage radius of the site.
 The density of the site distributing must be according with the distributing of traffic.
At the beginning of the building network, the important area and hot spot must be
covered well.
 At the city center, the height of small cell (the radius is about 1~3km) should be
higher the average height of the buildings but lower than the highest building . Some
micro cell, the antenna must lower than average height of the building. In the rural

area.
 The big building or some big building that will be built soon can’t block the antenna.
 Avoid build the site with radio station and radar station and other strong interference
source. If these kinds of location must be selected, the test of scanning the frequency
to find the frequency interference before building.
 Avoid building new site in the forest, if the site in the forest, the antenna must be
higher than the top of tree.
 The building, power, the place must be thought about.
 Select the cost low house as the new site location.
 If the location doesn’t affect the network quality, the exiting building and tower have
the priority as the location of new site.
2.2 Personal and equipment for site survey
Commonly the equipment is needed for site survey：
1．GPS
Globe Position System, Measure the longitude, latitude, attitude
2．Compass The direction
3．Test Mobile Test the signal
4．Rule
5．Telescopes (Optional)
6．（Digital）Camera(Optional)
7．Drive Test Equipment (Optional)
8．Car
Personal needed：
