Cellular Communication Network Technologies Cellular communication is a form of communication technology that enables the use of mobile phones . A mobile phone is a bidirectional radio that enables simultaneous transmission and reception.
Fiber optic communication is a communication technology that uses light pulses to transfer information from one point to another through an optical fiber. The information transmitted is essentially digital information generated by telephone systems, cable television companies, and computer systems. An optical fiber is a dielectric cylindrical waveguide made from low-loss materials, usually

is to direct information around the network, facilitating communication between all connected devices. However in new installations switches . 8 should be used instead of hubs as they are more effective and provide better performance. A switch, which is often termed a ‘smart hub’. Switches and hubs are technologies or ‘boxes’ to which computers, printers, and other networking devices are
No longer beholden to pen and parchment, people can now deliver massive amounts of data with the push of a button. New communication technologies have connected not only people but also businesses, changing the way people interact on a daily basis.
