Connectivity, be it mobile or internet, has become the backbone of people from all over the world. As the gamut of connectivity expands, encompassing the entire world and its remotest corners, it has brought with it the advantage of cost effectiveness.
What makes this kind of widespread connectivity possible? Apart from the satellites that sit high in the earth’s orbit, worth billions of dollars, it is the steel telecom towers that we see every day that enable us to “stay in touch”.
We may differentiate these towers into 3 main categories, mainly by the type of installation:
Guyed Tower
As the name suggests, guyed tower needs to be held in place by Guy Wires. Guy Wires are strong strands, generally made of steel, that are tied on end to the structure to be erected (a tower, for example) and the other end is bolted to the ground.
These tall standing structures are made of a variety of materials ranging from wood, plastic, and steel to concrete depending upon the height and geographical location of the tower. These are mainly used in point to point communication and sometimes for cellular operations.
Cell Tower
These are the commonly seen mobile telephony towers. They are named so because each tower is made up of 2 or more communication devices (like antennas) that make up a cell to create a network.
A cell tower may vary from a simple 2 device cell mounted on a single pole to a multi device tower mounted on a tall tower made up of steel sections. These kinds of towers are generally used by mobile phone communication operators including both, GSM and CDMA.
It is possible for a single cell tower to be used by multiple communication operators with different frequency and bandwidth requirements. The advantage of these types of cell towers is that natural foliage or tree cover does not hinder the communication network.
It is important to bear in mind that for a network to work effectively, there has to be a considerable overlap of signal between the next nearest cell tower.
Angular Tower
Like the name suggests, these are towers made of various angular sections of steel. The most common of the angles used are the L angles. These towers are generally self supporting and can rise to great heights. They are built in 3 or 4 legged configurations depending upon the space available versus the height required to be reached. The type of ground conditions also play a major role in deciding what the configuration of this tower should be.
An angular tower may be used to install cellular transceivers to radars to wind mills to surveillance equipment. These are truly multi utility towers.
Wow! your effort is great . You had done a good job by putting all the information about towers.I will send this to my friend who is working in towers project.Thank you.
