Pillars of Communication
We are dependent on communication networks every day. Communication is the lifeline of any society, and today, there are many companies that operate communication networks and help everyone perform their tasks with ease. These companies build the required infrastructure, such as telecom tower or radio tower and operate it to ensure connectivity at all times.
The Role of Radio Waves in Connectivity
For these companies to be able to maintain connectivity perpetually, it is important to have a strong network. This means that the radio waves that carry data, voice, or video have to be transmitted and received very effectively.
The radio waves are transmitted and received by antennae. An antenna is a conductor of radio waves which is used in transmission and receiving of these waves. Various types of antennae are used, depending on the type of wave or signal that is required to be transmitted or received.
For an antenna to effectively receive/ transmit radio waves, it must be placed at such a position to obtain maximum coverage. This is achieved by mounting the antenna at a high altitude, which is generally on an exclusive structure.
The structure that is created for the sole purpose of mounting antennae for telecommunication or radio communication is called telecom tower or radio tower.
Radio Tower Configuration
A telecom tower or radio tower can be of varying height and configuration depending on its usage requirement. A radio tower that is intended to transmit/receive video signals for a television may be as high as a few hundred meters, whereas a tower that is intended for phone signals may be only about 30 meters high.
Based on the height of the tower, the configuration also varies. A low rising tower for point to point radio communication may be built from a single pole made of wood or steel and tied down by means of strong steel cables called guys. Such a tower is called a guyed tower.
A cellular tower that may reach heights of about 15 - 30 m (about 5 to 10 stories high) may be built from steel segments welded together. Such a tower is called a lattice tower and is supported either on 3 or 4 legs.
A television or telecom tower (for local radio stations) which has a reach of a few hundred miles radius and stands at 150-300m may be built from concrete to give it the strength to resist wind speeds.
Radio Tower Characteristics
No matter what the type of construction of tower, every radio tower has a few common characteristics. Any radio tower will have an antenna mounting on which the antenna will be installed. It will have steps on the side of the radio tower with a railing for people to safely climb up and down the tower for installation, maintenance, and repairs whenever necessary. It will also have a light beacon on the top to denote the height and presence of the radio tower in the dark so that low flying aircraft do not crash into it.
These towers will also have a power supply at the base, usually in the form of a generator that provides power to the antenna and any other equipment that may be mounted on it.
All of this makes up a radio tower or a telecom tower, which helps maintain the network and connectivity at all times.
