In this article, you will know the factors that we have to observe to choose the amplifier – mobile coverage repeater that we need to solve the coverage problems.
WHERE THE HOUSING IS FOUND: URBAN AREA / RURAL AREA
It is the first thing we have to take into account since mobile phone companies use different frequencies to transmit VOICE and DATA services depending on the terrain orography, number of subscribers and the level of dispersion of the homes where it is intended to provide service.
TABLE OF FREQUENCIES USED FOR THE TRANSMISSION OF VOICE AND DATA SERVICES IN RURAL AND URBAN AREAS
In URBAN AREAS, where there is a greater number of subscribers, different frequencies are used to channel a large number of calls and connections made; On the other hand, in the RURAL AREAS, where there are fewer users connected to the same antenna, fewer channels (frequencies) are needed, and the propagation of the signal is a priority, that is to say, that the same telephone tower covers the largest possible territory.
As we can see in the previous table, we can receive voice calls for 900 MHz or 1800 MHz depending on the operator; although 3G is always transmitted by 2100 MHz, and 4G mainly by 1800 MHz.
IMPORTANT: The connection of3G is also used for the transmission of high-quality voice calls, so with a dual repeater of 900 – 2100 MHz we can improve the coverage of ALL COMPANIES. NON-OBSTANT, it is a necessary condition that all operators have 3G coverage outside the home or premises. If this is NOT the case, we only recommend these repeaters to Movistar and Vodafone users
EXPANSION OF HOUSING or LOCAL.
The larger the size of the house, we will need a device with greater power and more interior antennas to cover the different rooms/heights/ floors.
In this sense phone booster for Costa Rica , the material of the interior and forged walls will significantly determine the transmission of the signal. It is not the same that the walls are made of plasterboard, hollow bricks, or adobe; The more robust the walls/slabs, the lower the spread inside the house . as it happens in many old rural houses. In the latter case, it is preferable to opt for equipment with higher emission power.
If we need to service VARIOUS PLANTS or INDEPENDENT STAYS, the best option is to install a transmitting antenna on each floor. In these cases, we will need an amplifier that has enough power to power several indoor antennas. Urban models such as DOMIC 9-21 and DOMIC 9-18 perfectly support 2 indoor antennas; In rural areas, we recommend the TERRA 900 and ZEUS 900 amplifier equipment.
