A cellular network or mobile network is a communication network where the link to and from end nodes is wireless. The network is distributed over land areas called “cells”, each served by at least one fixed-location transceiver.
A Cellular network or Mobile network is a radio network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station.
What is cellular network used for?
Cellular networks are high-speed, high-capacity voice and data communication networks with enhanced multimedia and seamless roaming capabilities for supporting cellular devices. With the increase in popularity of cellular devices, these networks are used for more than just entertainment and phone calls.
How does cellular network work?
Very simply, a mobile phone network is made-up of a large number of geographic areas called ‘cells’. … Within these cells are mobile base stations which send and receive radio signals to and from mobile handsets located in those cells to enable their users to connect to the internet and make calls.
Why is it called cellular network?
They diagrammed a network of wireless towers into what they called a cellular layout. Cellular was the chosen term because each tower and its coverage map looked like a biological cell. Eventually, phones that operated on this type of wireless network were called cellular phones
How does cellular network connect to Internet?
A cellular network has a cluster of geographic locations together known as a ‘cell‘ which connect to the Internet through satellites. Each cell has a transmitting tower at its centre through which information is passed to and fro via digital radio waves.
Know more about Cellular Networks :
● When joined together these cells provide radio coverage over a wide geographic area.
● This enables a large number of portable transceivers (e.g., mobile phones, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations
What is the difference between WiFi and cellular connection?
Wifi uses radiofrequency waves to provide high-speed internet access to connected devices. Cellular networks are based on mobile phones and use networks spread over a wide area. WiFi is a wireless network technology following IEEE 802.11 standards. Cellular networks are dependent on network range availability.
Advantages of Cellular networks :
● It is flexible enough to use the features and functions of almost all public and private networks.
● It has increased capacity.
● It consumes less power.
● It can be distributed to larger coverage area.
● It reduces interference from other signals.
Disadvantages of Cellular Systems
Some of the disadvantages of cellular systems are:
1. Infrastructure needed
Small cells require a complex infrastructure to connect all base station. The infrastructure required includes switches for call forwarding, location registers etc.
2. Handover needed
The mobile station has to perform a handover when changing from one cell to another very frequently.
3. Frequency planning
To avoid interference, frequency spectrum should be distributed properly with a very less range of frequency spectrum.
