Whois & Analysis for frequencycheck.com

A cellular network or mobile network is a communication network where the last link is wireless.

The network is distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station.

This base station provides the cell with the network coverage which can be used for transmission of voice, data and others.

A cell might use a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell.

Wireless communication, or sometimes simply wireless, is the transfer of information or power between two or more points that are not connected by an electrical conductor.

The most common wireless technologies use radio waves.

With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications.

It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking.

Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones.

A computer network or data network is a telecommunications network which allows nodes to share resources.

In computer networks, networked computing devices exchange data with each other using a data link.

The connections between nodes are established using either cable media or wireless media.

The best-known computer network is the Internet.

A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly.

A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user.

the frequency band is an interval in the frequency domain, delimited by a lower frequency and an upper frequency.

The term may refer to a radio band or an interval of some other spectrum.
