How is optical fiber used in communication networks? What is wireless network? What is a computer network? What is a wireless local area network? Is the frequency spectrum required or provided by communication networks? What is a network externality? What are the challenges that are caused by ...
The development of the information technology never halts, it is capable of providing comprehensive information at a fantastic speed. Thanks to the development of advanced information technology such us WLAN wireless technology, optical communication network and cloud computing, instant informatio...
Short for light fidelity, Li-Fi or LiFi is a bidirectional wireless communication technology that uses visible light to transmit data. More specifically, it is a form of OWC (Optical Wireless Communication) that relies on LEDs (light-emitting diodes) to transfer data and position signals between...
Optical media also uses light, usually through fiber optic cables. This method is great for sending large amounts of data quickly and over long distances with very little signal loss. These types of communication media are chosen based on the network’s needs, such as how far the data ...
♦ Your contact’s schedule if there are specific days that he or she is at a certain location. ♦ Be sure to include every piece of information you can. Why? When people are injured in a regional emergency, like a tornado or an earthquake, not every type of communication will be ...
An optical-fiber cable can transmit much more information than an electrical cable of the same size. A major application of optical-fiber cable is in linking telephone switching offices. Many communication companies have installed large networks of fiber-optic cables across the continents and under ...
What is an optoisolator (optical coupler or optocoupler)? An optoisolator (also known as an optical coupler, photocoupler, optocoupler) is asemiconductordevice that transfers an electrical signal between isolated circuits using light. These electronic components are used in a wide variety of communic...
into different types like messaging, voice call, e-mail, social media, etc. We know that e-communication has changed due to the way public interact and communicate with each other for different purposes like personal or business. By using this, it is very simple to communicate with the ...
into a single device called atransceiver. The medium of signal transmission can be via electrical wire or cable -- also known ascopper-- optical fiber, electromagnetic fields or light. The free space transmission and reception of data by means of electromagnetic fields is calledwireless...
What is optical fiber? Optical fiber consists of a core that confines a light and a cladding that reflects it. Confined in the core, the light travels through it as it is reflected by the cladding.
