Impacts of Emerging Technologies: Analysis of the emerging technologies and their potential impact on the telecommunications industry.
Telecommunication Standards: Overview of telecommunication standards including 3G, 4G, and 5G networks.
Analog communication: This type of communication involves the transmission of analog signals that vary continuously over time, such as sound waves or radio waves.
Digital communication: In this type of communication, information is transmitted using digital signals, which are discrete and quantized. These signals can be represented using binary code.
Wireless communication: This type of communication involves the transmission of information over a wireless channel, such as radio waves or infrared signals.
Wired communication: This involves the use of physical cables to transmit information, such as Ethernet cables, coaxial cables, or fiber optics.
Optical communication: This involves the use of light signals to transmit information, such as fiber optics.
Radio communication: This involves the use of radio signals to transmit information over a long distance, such as radio broadcasting or satellite communication.
Satellite communication: This involves the use of communication satellites in orbit to relay information between two or more points on Earth.
Microwave communication: This involves the use of microwaves to transmit information over short distances, such as in microwave ovens or cell phone towers.
Infrared communication: This involves the use of infrared signals to transmit information between devices, such as TV remotes or computer keyboards.
Bluetooth communication: This involves the use of short-range wireless technology to transmit information between devices, such as between a smartphone and a wireless headset.
Wi-Fi communication: This involves the use of wireless local area network technology to transmit information between devices over a local network, such as in a home or office.
Cellular communication: This involves the use of cellular networks and wireless technology to transmit information between mobile devices, such as smartphones or tablets.
VoIP communication: This involves the use of internet protocol (IP) technology to transmit voice calls over the internet, such as through services like Skype or Zoom.
Video conferencing: This involves the use of technology to transmit audio and video between two or more people in different locations, such as through videoconferencing software or webcams.
Unified communications: This involves the integration of multiple communication methods, such as email, instant messaging, voice calls, and video calls, into a single platform or system.
- "The precise definition of communication is disputed."
- "Many models include the idea that a source uses a coding system to express information in the form of a message." - "The source uses a channel to send the message to a receiver who has to decode it in order to understand its meaning."
- "Communication can be classified based on whether information is exchanged between humans, members of other species, or non-living entities such as computers."
- "Verbal communication involves the exchange of messages in linguistic form." - "Non-verbal communication happens without the use of a linguistic system."
- "There are many forms of non-verbal communication, for example, using body language, body position, touch, and intonation."
- "Interpersonal communication happens between distinct persons, such as greeting someone on the street or making a phone call."
- "Intrapersonal communication, on the other hand, is communication with oneself."
- "Researchers in this field often formulate additional criteria for their definition of communicative behavior." - "Example are the requirement that the behavior serves a beneficial function for natural selection and that a response to the message is observed."
- "Animal communication plays important roles for various species in the areas of courtship and mating, parent-offspring relations, social relations, navigation, self-defense, and territoriality."
- "An often-discussed example concerning navigational communication is the waggle dance used by bees to indicate to other bees where flowers are located."
- "Due to the rigid cell walls of plants, their communication often happens through chemical means rather than movement."
- "For example, plants like maple trees release so-called volatile organic compounds into the air to transmit warning signals about a herbivore attack to other plants."
- "The reason is that its purpose, as a tool, is usually some form of cooperation, which is not as common between different species."
- "For example, many flowers use symmetrical shapes and colors that stand out from their surroundings in order to signal to insects where nectar is located to attract them."
- "Communicative competence is the ability to communicate well."
- "Two central aspects are that the communicative behavior is effective, i.e. that it achieves the individual's goal, and that it is appropriate, i.e. that it follows social standards and expectations."
- "Human communication has a long history and how people exchange information has changed over time."
- "Examples are the invention of writing systems, the development of mass printing, the use of radio and television, and the invention of the internet."
- "The field of communication includes various other issues, like communicative competence and the history of communication."
