It was the first wireless transmission in the history of science.
Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors. Let’s take a look on the evolution stages of wireless technologies for mobile communication. 802.11n also offers a somewhat better range over … This is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Get kids back-to-school ready with Expedition: Learn! Wireless communication refers to the transfer of information among two or more points without an electrical conductor. Marconi, an Italian inventor, transmitted Morse code signals using radio waves wirelessly to a distance of 3.2 KMs in 1895.
WIRELESS HISTORY FOUNDATION | PO BOX 351618, Westminster, CO 80035 | Design & Maintenance by: Enjen Consulting The Eastern Telegraph Company and Marconi supported the war effort through the War Office and the Admiralty by offering expertise in keeping communication open around the world, through censorship, listening in, field work and in confusing the enemy.
Wireless devices include cell phones, two-way radios, remote garage-door openers, television remote controls, and GPS receivers (see Global Positioning System).
The most common wireless technologies use radio.
Wireless microphones send their signal to the mixing desk via a small low-power FM radio transmitter hidden somewhere on the actor.
Wireless Communication can be classified into three eras.

2008. The development of affordable miniaturized wireless microphones in the 1980s significantly improved vocal reinforcement.
This article gives an overview of wireless communication and types of wireless communications.
The principles of wireless communication theory are covered with emphasis on the essential concept delivery to non-major learners in the easiest way. 802.11n (also sometimes known as Wireless N) was designed to improve on 802.11g in the amount of bandwidth it supports, by using several wireless signals and antennas (called MIMO technology) instead of one. Industry standards groups ratified 802.11n in 2009 with specifications providing for up to 300 Mbps of network bandwidth. The market interest in enhanced communication systems was also clearly illustrated by the fact that in 1860 the Pony Express started regular physical message services over land in the U.S.
There are more than 285.6 million U.S. wireless subscriber connections which is approximately 91% of the total U.S. population.
History of wireless technology.
Wireless communication was a magic to our ancestors but Marconi could initiate it with his wireless telegraph in 1895.

In the present days, the wireless communication technology refers to a variety of wireless communication devices and technologies ranging from smart phones to computers, tabs, laptops, Bluetooth Technology, printers. Wireless communications is a type of data communication that is performed and delivered wirelessly.
Wireless communications are employed in many smart grid applications, such as meter data collection, demand management, substation and power line monitoring and protection.
Pioneer Era (Till 1920) Pre Cellular Era(1920-1979) Cellular Era (beyond 1979) The first commercial mobile telephone system was launched by BELL in St. Louis, USA, in 1946.
Wireless communications, System using radio-frequency, infrared, microwave, or other types of electromagnetic or acoustic waves in place of wires, cables, or fibre optics to transmit signals or data.
This course will provide an introduction and history of cellular communication systems that have changed our lives during the recent four decades and will become an essential and inseparable part of human life.
Wireless and cable telegraphy were important tools of communication in the First World War. The microphone is often placed in the actor’s hair or mounted on a flesh-coloured headset…
2008 But at the same time, electronic systems for communication had started to develop.
The wireless era Wireless communication is the electromagnetic transfer of information between two or more points that are not connected by an electrical conductor.The most common wireless technologies use radio waves.With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications.
