How Do Wireless Speakers Work?
Magic? Harry Potter Wand Tricks? Leprechauns?
There can be truly no straightforward answer to This particular question. Wireless speakers can work on a variety of technologies, chief among them being Radio Frequency (RF), Bluetooth, in addition to nowadays, even Wi-Fi.
The basic process, however, remains the same. A wireless transmitter can be plugged into an audio system such as an iPod, a computer, a Blu-Ray player, a TV, etc. This particular transmitter sends a signal to the speakers which, in turn, convert that will into sound. The signal can be transmitted via various different technologies, which we’ll discuss below.
Radio Frequency or RF, can be the most common technology used in wireless speakers. The speakers use a particular unused band of the radio spectrum to transmit data wirelessly. A cordless phone works on the same principle.
RF can be a fairly efficient technology, flexible in addition to affordable. that will features a Great range, stretching over 100 feet in certain designs (in addition to over 300 feet in some outdoor speakers). There can be a fair amount of data loss which can cause degradation of the audio signal, resulting in poor quality playback. Conflicting signals via additional wireless devices inside house, such as wireless routers in addition to cordless phones can cause interference, leading to data loss in addition to disturbance. All in all, RF, despite its popularity, may be phased out inside next few years as newer technologies take its place.
If you bought a completely new mobile phone inside past 2 years, you would certainly definitely be familiar with Bluetooth. As a wireless data transfer standard used in virtually every mobile phone, Bluetooth can be ubiquitous these days. Via This particular technology, two Bluetooth enabled devices can be connected wirelessly within seconds. Once a connection can be established, data can be transferred wirelessly at speeds of up to 3 MB/second.
Technologically, Bluetooth works on the radio spectrum as well. Instead of using just one band, however, Bluetooth chops up the data in addition to distributes that will over 79 different bands, thereby enhancing speed in addition to reducing data loss. These bands range via 2400 MHz to 2483.5 MHz.
Bluetooth features a smaller range than pure RF signals. On the plus side, since the entire spectrum via 2400-2483.5 MHz (79 bands, along with spare guard bands) can be allocated for Bluetooth use, there can be no interference via additional wireless devices.
One key issue with Bluetooth can be that will that will isn’t available in all devices. Older phones, most audio in addition to video players, TVs, in addition to desktop computer aren’t equipped with native Bluetooth. To use a pair of Bluetooth wireless speakers with these devices, you’ll have to invest in a Bluetooth transmitter. However, if you primarily use a Bluetooth enabled device such as an iPhone or iPod Touch to listen to your music, you’ll find Bluetooth wireless speakers to be a competent competitor to RF.
Only a select few speakers use Wi-Fi for transmitting data – such as the Sonos Play series of speakers. This particular can be the same plain vanilla Wi-Fi used in your home. that will can be fast in addition to efficient in addition to works very well with digital, Wi-Fi enabled devices like computers in addition to mobile phones.
However, most audio players, TVs, etc. aren’t Wi-Fi enabled. This particular means that will a Wi-Fi wireless speaker can only play back audio via your computer or mobile phone. Obviously, This particular limits its functionality in addition to can be the sole reason why wireless Wi-Fi speakers haven’t been accepted by the mainstream.
