In the past few years, five models of cellular phones have been introduced. While they are of different types, they all share one common feature: they can use the much higher frequency signals available in mobile coverage.
A regular tower is the major component of a traditional phone. It is composed of a base station and a dish antenna at the top.
With the latest mobile phones, the towers are upgraded with amplifiers that improve their signal strength. The result is that they can send and receive much stronger signals than the older buildings could. We also use this technology for amplifying satellite communications. A common misconception about this technology is that it will not transmit as many frequencies as a traditional tower.
There are two basic types of wireless phone technology. There are two types of towers for them too. A single radio transmitter and receiver, or radio access point, is used for mobile communication. We call these “PCAP (personal digital assistant) devices”.
A cell phone has two antennas that can work together with the radio access points to make wireless connections. One antenna is the BSC (base station connector). It is attached to the base station. The other antenna is the GSM (GPS mobile subscriber modem). This device is used to communicate with the network of the base station.
Towers are designed in a specific way. The antenna at the top of the tower is placed in the correct position to receive the satellite signals and direct it to the appropriate reception point on the ground. When there is no reception, then the antenna must stop transmitting. This device, called the repeater, is programmed to pick up the signal again and re-transmit it.
A tower is usually installed at an altitude above ground level. We know this as the roof height. However, it is also possible to build the tower at ground level. We know this as the floor height. The size of the tower can vary according to the cellular phones that are being used.
Some tower designs are so small that the antenna and the satellite that are connected are not visible from the ground. Sometimes, the tower can be hidden inside a building and not seen from the ground.
Once the antenna is placed inside the building, it is covered with a roofing tile. This tile also serves to provide roofing support. The roof covers the antenna when not in use and when the antenna is transmitting. Then there is another piece of roofing that supports the repeater. The repeater is usually installed in a place where there is adequate room to fit it.
The cell-phone towers are usually located higher on a building. They can be as high as 50 feet. Sometimes they can reach the attic of the home. They can be as low as one meter off the ground. If there is over one tower, it is possible that we can space them in different areas of the building.
You must consider the time to install and maintain the tower. If you live in an area prone to inclement weather, then the best option may be to place the building outside.
Tower maintenance is usually done annually. Each year the weather is monitored, and a schedule is put in place to see what kind of weather the tower will have to deal with.
After the weather has been monitored, the tower is brought out, and any parts that need repairing are replaced. In the meantime, the antenna is set up, and it is turned back on. The new antenna is tested before it is placed back in the building.
