Transmission of multimedia data over wireless

An exabyte is one billion gigabytes. As shown in picture above, multiple antennas can be aligned to reach farther. Wireless communication involves no physical link established between two or more devices, communicating wirelessly.

For example, in case of conventions, meetings in which the laptops and the other devices are connected in a wireless network in order to exchange data and share resources, like a printer,… etc. The current tendency is to replace traditional telecommunication services by packet mode communication such as IP telephony and IPTV.

Note that the term line rate in some textbooks is defined as gross bit rate, [13] in others as net bit rate. Facilitating ever growing and expanding networks, passive infrastructure is set to increase as demand for global telecommunications infrastructure advances.

Goodput Goodput or data transfer rate refers to the achieved average net bit rate that is delivered to the application layerexclusive of all protocol overhead, data packets retransmissions, etc.

Digital multimedia is the field concerned with the computer controlled integration of text, graphics, still and moving images, animation, sounds, and any other medium where every type of information can be represented, stored, transmitted, and processed digitally.

Supported and complemented by cabling infrastructure, wireless is a core part of effective networks.

The details of 5G are a long way from being decided but it is expected to provide Internet connections 40 times faster and with at least four times more coverage worldwide than the current 4G Long Term Evolution LTE wireless communications standard. More than one antenna operating in the same frequency range can also send multiple streams of data, increasing the data rate.

What can be done to overcome these limitations. This allows us to detect relevant quantities, monitor and collect data, formulate clear user displays, and to perform decision-making functions [22] Wireless data communications are used to span a distance beyond the capabilities of typical cabling in point-to-point communication and point-to-multipoint communicationto provide a backup communications link in case of normal network failure, to link portable or temporary workstations, to overcome situations where normal cabling is difficult or financially impractical, or to remotely connect mobile users or networks.

Information rate[ edit ] The physical layer net bitrate, [11] information rate, [5] useful bit rate, [12] payload rate, [13] net data transfer rate, [8] coded transmission rate, [6] effective data rate [6] or wire speed informal language of a digital communication channel is the capacity excluding the physical layer protocol overhead, for example time division multiplex TDM framing bitsredundant forward error correction FEC codes, equalizer training symbols and other channel coding.

Advertisement Every decade or so since the first cellular networks appeared the companies that make mobile devices and the networks linking them have worked out new requirements defining transmission speeds, capacity and other technical characteristics.

This method is used internally within the computer, for example the internal buses, and sometimes externally for such things as printers, The major issue with this is "skewing" because the wires in parallel data transmission have slightly different properties not intentionally so some bits may arrive before others, which may corrupt the message.

Digital signals can also be sampled instead of continuously monitored. The "connection speed" of a V.

The fundamental theoretical work in data transmission and information theory by Harry NyquistRalph HartleyClaude Shannon and others during the early 20th century, was done with these applications in mind. Error-correcting codes are common especially in wireless communication systems, broadband modem standards and modern copper-based high-speed LANs.

Types of communication channels Network topologies [ edit ]. Radio waves of high frequencies are prone to be absorbed by rain and other obstacles. Because of frequency light uses, it tends to travel strictly in straight line. In that context, the term peak bitrate denotes the net bitrate of the fastest and least robust transmission mode, used for example when the distance is very short between sender and transmitter.

The channel capacityalso known as the Shannon capacity, is a theoretical upper bound for the maximum net bitrate, exclusive of forward error correction coding, that is possible without bit errors for a certain physical analog node-to-node communication link.

They sense the channel conditions and adapt the modulation scheme to obtain the highest data rate for the given conditions. The next generation—5G wireless—will have to deliver a huge leap in performance to handle surging mobile network traffic, much of which will be large multimedia files.
