Wi-Fi radios are electronic devices of similar appearance to conventional transistors, which allow you to tune the signal transmitted by the Internet radio stations via Wi-Fi. They are to promote its implementation, many Wi-Fi radios available in addition to AM/FM radio or DAB digital radio receiver or both, so they are very versatile devices that allow you to tune to different radio systems, the conventional AM/FM radio, terrestrial Digital Radio and Internet radio. Unlike television radio technologies, where the analogue blackout led to the disappearance of analogue TV and its replacement by the DTT (Digital Terrestrial Television), radio scanning progresses very slowly. There are currently several technologies that allow to emit radio channels: AM/FM Radio: is the conventional radio. Digital terrestrial radio: known as DAB radio (Digital Audio Broadcasting), is a present digital radio technology since 1995, is however little extended by the necessity of having a receiver specific. Satellite radio: is only implemented in United States, where it is cost-effective because the population is scattered and the area covered is very large. You need specific receptors.
Internet radio: is experiencing tremendous growth, both in its podcast version by means of streaming. Is it tuned with any device that can access the Internet, such as a computer or a mobile phone, but there are specific devices for this function, called Wi-Fi radios. Wi-Fi Wi-Fi radios radios are similar in appearance to conventional radios with digital display, however do not tuned the usual radio waves but that are connected to the Internet via Wi-Fi to play the broadcasts of radio on the Internet. Wi-Fi radios allow access in any place that has Wi-Fi connection to the vast amount of available Internet stations, until now only accessible from the computer. Let’s look at the main features of the Wi-Fi radios: Wi-Fi: they have Wi-Fi antenna built-in or external, as well as encryption WEP, WPA and WPA2. Graphical environment: to dial mode.
Sound output: allows you to connect headphones, external speakers or an amplifier. Alimentation: they have rechargeable batteries. Connectivity cable: many Wi-Fi radios include Ethernet connector for cord usage if it is available. Formats: Wi-Fi radios read the most common formats of compressed audio, like MP3, WMA, Real Audio or AAC. Stations: usually Wi-Fi radios connect to directories of radio stations, such as Reciva or vTuner, to obtain addresses of stations, also allowing you to add strings manually. Feature speaker: some models serve as a computer speaker Wi-Fi, allowing listening to music that plays the PC. Speaker iPod function: some models of Wi-Fi radios have adapter for iPod serving as speaker for the iPod. Alarm function: many Wi-Fi radios incorporate wake up to start the day with the favorite Internet radio station. Hybrid models: some models include AM/FM tuner or DAB digital tuner, so disposing of several functions in a single device.
