The telecommunications Networks


The Advanced Research Projects Agency Network (ARPANET) was an early packet-switching network and the first network to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet.


Ethernet /ˈθərnɛt/ is a family of computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN).[1] It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3, and has since retained a good deal of backward compatibility and been refined to support higher bit rates and longer link distances. 


The Internet (portmanteau of interconnected network) is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

Wireless network

A wireless network is a computer network that uses wireless data connections between network nodes.[1]

Wireless networking is a method by which homes, telecommunications networks and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.[2] admin telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure.[3]

Public switched telephone network

he public switched telephone network (PSTN) is the aggregate of the world’s circuit-switched telephone networks that are operated by national, regional, or local telephony operators, providing infrastructure and services for public telecommunication. The PSTN consists of telephone lines, fiber optic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables, all interconnected by switching centers, thus allowing most telephones to communicate with each other. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital in its core network and includes mobile[1] and other networks, as well as fixed telephones

Packet switching

Packet switching is a method of grouping data that is transmitted over a digital network into packets. Packets are made of a header and a payload. Data in the header are used by networking hardware to direct the packet to its destination where the payload is extracted and used by application software. Packet switching is the primary basis for data communications in computer networks worldwide.

Radio network

There are two types of radio network currently in use around the world: the one-to-many (simplex communication) broadcast network commonly used for public information and mass-media entertainment, and the two-way radio (duplex communication) type used more commonly for public safety and public services such as police, fire, taxicabs, and delivery services. Cell phones are able to send and receive simultaneously by using two different frequencies at the same time. Many of the same components and much of the same basic technology applies to all three.

Television network

A television network is a telecommunications network for distribution of television program content, whereby a central operation provides programming to many television stations or pay television providers. Until the mid-1980s, television programming in most countries of the world was dominated by a small number of terrestrial networks. Many early television networks (such as the BBC, NBC or CBC) evolved from earlier radio networks.

Future technologies that might work.

The evolution of AI-based network architectures alongside with advanced sensory digitization and revolutionary compression algorithms disrupted the telecommunications industry in the 2030s.

Humans started to engage in remote hyper-experiential connections where all five senses were accurately digitized. Till today, people are referring to it as teleportation, but the technical label, which was coined by a bunch of visionaries in the late 2010s, is ‘holographic telepresence’.

Ineluctable ego- and power-driven conflicts indeed manifested during the infant age of this technology, but the widespread empathetic response generated by such a transparent, immersive, real-time multi-sensorial communications paradigm, ultimately allowed to bridge cultural and societal gaps across continents.

In the meantime, research breakthroughs in computer- and neuro-science provided humans with sophisticated tools to assess their own psychological states aimed at improving their well-being. This technology blossomed in the late 2030s, and allowed mankind to reach a higher collective consciousness. Along these lines, the last fundamental transition before stepping into our age stems from further disruptive technological advancements that took place in the 2040s.
