In order to provide services to introduce the trunking infra-structure it is necessary to design a project for the radio-communication system. The stages are as follows:

1 -Technical Inspection– Site Survey

The Site Survey is necessary to collect all data on the location where the system will be installed, such as:

1- Obtaining geographic coordinates of the locality in exploring the use of GPS equipment.
2- Enabling the design and correct location of the infra-structure being proposed and designed (shelter, tower, line, power, conduit, etc.).
3- Obtaining photos, recording relevant details for the project design.
List of all resources needed for the deployment of the system (labor, materials, equipment etc).


2 - Legalization Systems/ANATEL

ANATEL -The National Telecommunications Agency in Brazil, which controls the use of radiofrequency in the country, collects fees for the authorization and use of frequencies. It is essential to prepare a draft of Radiofrequency Legalization by a specialist engineer. The project consists of the completion of several special forms and the making of a report of compliance for each radio station, required since July 2002, when the ANATEL resolution 303 came into force approving the Regulation on Limitation of Exposure to Electromagnetic Fields in radio frequency band between 9kHz and 300GHz.

After reviewing and approving the project presented, Anatel authorizes the use of the system, through the issuance of a license for each radio station.

3 - Propagation Studies

The propagation studies are intended to provide the initial performance of a RF link or area of coverage of a radio system.

To obtain this prediction it is necessary to obtain information from various geographical regions of the inspected area: topographical maps and profiles, possible obstacles (buildings, trees and mountains) and even potential problems, such as the reflection of radiofrequency signal through a mirror of water, for example.

Finally, using specific software and optimized calculations based on practical measures taken in the field, the images are obtained which demonstrate the viability of the system you want, including the design of minimum infra-structure (tower) necessary to ensure the efficiency of the system


4 - Executive Project in CAD

The Executive Projects in CAD are necessary to organize, represent and define the entire structure involved in the conduct of a project, providing subsidies to the coding and location of the equipment in the system. The level of detail depends on the complexity of the study of the venture.
This is the usual feature:

1- Map of access;
2- Design projecting where they will be shown through longitudinal and latitudinal cuts;
3- Location and display of equipment;
4- Others.
