Telecommunication has evolved over the years. From a simple landline, to a pager system, and then the mobile handsets has become a member of every household. It has made our lives convenient and easy. All we have to do is pick up our handset, dial and there we go! It’s all done and sounds so simple. If we stop to think, just for a second as to what is involved in the backdrop of the call connectivity? What makes one call connect to another? How is it that we are able to connect in a few seconds and communicate? Well, here lies the answer to these questions. There is a whole process that happens from the time we dial the number to the point it is connected to the person on the other end. The radio waves travel from one place to another facilitating the call. It does so, with the help of a network called Radio Access Network (or) RAN.
In the technology and the wireless era (signals travelling with the help of devices or a chip instead through wires) for a telecommunication to be work the manner it is meant to be, one needs a strong radio access network. Let us get some perspective and understanding of this radio access network and its related aspects.
A Radio Access Network (RAN) implements a radio access technology and is part of a mobile telecommunication system. It is like the invisible master doing the magic in connecting one device to another. It conceptually resides between any two communicating devices such as a mobile phone, a computer or a laptop, or a remotely controlled machine connecting it to its core network (CN).
