wireless devices Guide
wirelesss can be an alternative to the conventional ones mobilebe in contact with friends and acquaintances. The contact with the radio is always free of charge, since the radio signals do not have to be routed through a broad radio network provided as the mobile phone. The provision and maintenance of such a wireless network costs money, which then has to be transferred to the users. Therefore, the phone calls with the mobile phone also charges. With a radio, however, only costs incurred by the purchase. The operation itself is then free, as the radio signals are sent directly to the receiver device. The disadvantage, however, that transmitter and receiver must have the same radio, or the same radio standard and the relatively short range phones compared.
The history of radios
In 1864, the radio waves were discovered by James Clerk Maxwell. In 1888, the existence was confirmed experimentally by Heinrich Hertz. Guglielmo Marconi made the first radio connection in 1895 with the help of a pop radio transmitter over the distance of 5 kilometers. This enabled messaging through Morse code. After Alexander Meißner discovered the oscillator circuit in 1913 with the help of an electron tube, further types of modulation could be developed, which in turn was the prerequisite for a permanent output and the subsequent transmission of sound and image. Until 1930, there were only stationary radios that have been built into ships or aircraft, for example. The armaments industry, however, drove the research forward, making ever smaller devices possible, which could also be used in trucks. At the end of the Second World War, the transmitter and the development of semiconductors brought a new technology to bear, the one to be carried by the mobile radios made possible.
Hand-held radios are about as big and heavy as commercial cell phones, but usually have one antenna, For beginners, the manufacturers offer inexpensive entry-level models, which usually consist of two radios. However, there are also individual devices that are equipped with special functions and are suitable for both private and professional use. The difference to a cell phone is that you can either talk or hear with a radio. Both at the same time does not work. During speech, a transmit button must be pressed to send the radio signals. To hear the button must be released. Some devices also work via voice recognition. In this case, pressing the PTT button is not necessary because these devices detect when someone speaks and then release the channel. Usually you do not have to hold the radio to the ear, because radios about one speakerfeature.
The wireless standard
If friends or work colleagues want to spark each other, they need radios that are equipped with the same wireless standard:
The most well-known radio standard for laymen is the somewhat older CB radio, which is standard in many trucks, for example.
– The SRD (short range devices) is a short-range radio for short-range devices.
– The PMR446 stands for Private Mobile radioand is suitable for multiple radios in a group.
– The DMR 446 is the counterpart on a digital basis.
