LOCATION, HEIGHT AND TYPE OF TOWERS

Cell phones are working with sophisticated radio frequencies that cover or cover areas or cells of a certain diameter. Radio Frequency and Transmission departments determine the location of these antennas, and height to work properly. Once given the location, where it has a radius of approximation, we proceed to visit the area and find a suitable place for installation of the tower.

This area may fall on a house, and proceeds to make a survey of the property, and check your height, so you know the height of the tower to be built. You must also check that the property is in good conditions to get to the tower.

If the area is an area, then it can be self-supporting tower or monopole. 

EQUIPMENT

When building these towers, installing antennas on top, bottom and install additional equipment for its operation. For example, containers can be heavy (in the analysis are generally considered Ton weight 9). This is for older systems, because new equipment weigh hardly anything, such as GSM equipment weighing as 0.5 Ton

The antennas are parabolic shape, and to calculate wind forces on these, it resorts to using experimental data from the manufacturer.

Thus, to install all the equipment and operate correctly is coming to the use of the structure to what was built. There are times in the same structure are more than one team as the company that has built the tower, you can hire another company to also install their equipment.

ANALYSIS OF CHARGES

Below are the charges that are considered for the design of a telecommunications tower:

Dead Load .- cellular antennas, parables, feeders, waveguide bed, ladder, platform Triangular and / or rest (if applicable). 
The dead load for the weight of the antennas are taken directly from the information provided by the manufacturer. 

Live Load .- The personnel for installation. It is generally considered 300kgs (100lbs 3 people each). 

Analysis of wind forces .- The wind loads are generally calculated using a dynamic analysis.

In the case of wind loads on the structure, these are obtained through formulas stipulated in the relevant regulations for each country, for example, in the United States is calculated using the AESCregulation in Mexico through the regulation of CFE, Argentina CIRSOC through regulation. In these formulas are calculated exposure areas of structural elements, which are usually multiplied by other factors.

To calculate wind forces but now on satellite and parables, can be calculated from experimental measurements taken by the equipment manufacturers, such as Andrew antennas that are more commercial.
