Working Of WLAN

Transmission Means
Wireless network of failing have two kinds of radio waves and infrared rays ways.
The transmission ray transmission means is influenced by distance very big.
The application of radiowave transmission means is much more extensive.
Modulation Way Of The Radiowave
Expand the spectral way.The frequency spectrum of the signal of the data is and then transmitted out after being expanded into several times even dozens of times.
Modulate the way in narrowband.The signal of the data is transmitted out directly in case of not making any expansion

Each inverter is tested before shipping and are 100% working.
Early inverters,inverter is an inverted converter.The origins of electromechanical inverters explain the source of the term inverter. Early AC-to-DC converters used an induction or synchronous AC motor direct-connected to a generator (dynamo) so that the generator's commutator reversed its connections at exactly the right moments to produce DC. A later development is the synchronous converter, in which the motor and generator windings are combined into one armature, with slip rings at one end and a commutator at the other and only one field frame. The result with either is AC-in, DC-out. With an M-G set, the DC can be considered to be separately generated from the AC; with a synchronous converter, in a certain sense it can be considered to be "mechanically rectified AC". Given the right auxiliary and control equipment, an M-G set or rotary converter can be "run backwards", converting DC to AC.

About WLAN

WLAN is a computer LAN (Local area network) of Wireless Channel as transfer media, and is the result of the computer network and wireless communication technology, wireless with many address as its transfer media, supply the traditional function of LAN, Make sure the user can be easily connect wide band at any moment and anywhere.
WLAN technology makes the computer on net can have moving nature, can solve the problem of feeding through of network channel that the wired way is difficult to realize fast , conveniently . WLAN utilizes the electromagnetic wave to send and receive the data in the air, but does not need cable medium.
WLAN's advantage,First let us think about why we should use WLAN, Firstly, Don’t you think it is a boring work to lay the cable and check the cable if it is break off or not, Moreover, due to the cooperation for the company and the ceaseless development of the application environment, the company internet should be distribution again, and install the network line again, and the third is the cost could be very high if we ask engineer to lay the cable, so install WLAN is the best way to resolve all the problem.
One wireless LAN can regard as wired expansion of LAN use, can be regarded as the substituting facilities of the wired LAN independently too, so the wireless LAN has offered very strong network flexibility of group. The wireless LAN (WLAN ) the growth of technology started in the middle period of the eighties of the 20th century, it union communicate committee (FCC ) for industry, scientific research and medical science(ISM) frequency band public to employ , offer , authorize and produce by American. This policy makes every big company and end user not need to get FCC licence , can employ the wireless products , thus promote development and application of WLAN technology. Transmit a different one through copper wire or optic fibre conductor with wired LAN, the wireless LAN uses electromagnetic spectrum to transmit information. Similar to radio broadcasting and TV, the wireless LAN uses the channel (Airwave ) to send information. Transmit , can realize by using wireless microwave or infrared ray , require effective frequency used and send the level standard of the power, within the range that the government organ allows.
I will introduce the advantage of WLAN in 6 aspects
The first: The security aspect ;Secondly: the install of WLAN is very easily, Don’t need license with many lines;Thirdly : application scope is very broad, not like wire network, it can transfer so far away without any condition;Fourthly: economy, WLAN is not confined by the position of the wire connecting , but very flexible;Fifthly: easily to expanding, can be flexible to choose many kinds of collocation manner;Sixthly: With high speed transfer, the speed could be to 11Mbit/s, and the distance could be over 20Km .
The wireless office land network is a quite convenient data transmission system, it utilizes technology of the radio frequency, replace office land network that old-fashioned paired line that get in the way form , make wireless office land network can utilize simple access build up , let user see through it.

Following about Keyboard switch matrix.The keyboard switch matrix has a switch at some or all intersections, much like a multiplexed display. Almost all keyboards have only the switch at each intersection, which causes "ghost keys" and "key jamming" when multiple keys are pressed ,Without generating erronous ghost keys. Often more expensive keyboards have a diode between each intersection, allowing the keyboard microcontroller to accurately sense any number of simultaneous keys being pressed. Keyboard switch matrix is often drawn with horizontal wires and vertical wires in a grid which is called a matrix circuit.

From the late nineteenth century through the middle of the twentieth century, DC-to-AC power conversion was accomplished using rotary converters or motor-generator sets (M-G sets). In the early twentieth century, vacuum tubes and gas filled tubes began to be used as switches in inverter circuits. The most widely used type of tube was the thyratron.
