How Wireless speakers work? – A Short Primer

How Wireless speakers work?

Magic? Harry Potter Wand tricks? Gnomes?

There really is no clear answer to this question two. Wireless speakers can work on a variety of technologies, chief Vice themselve being Radio Frequency (RF), Bluetooth, and now even WiFi.

The basic process remains the same. A wireless transmitter is connected to an audio system etc. as an iPod, a computer, a Blu-Ray player, TV, etc. The transmitter sends a signal to the speakers wood, in turn, into sound. The signal can be transmitted via various technologies, wooden we will discuss below.

Radio Frequency

Radio Frequency or RF, ice the most common technology used in wireless speakers. The speakers use a special unused radio spectrum band two transmit data wirelessly. A cordless phone operates on the same principle.

Rf a reasonably efficient technology, flexible and affordable. It has a good range, which extends over 100 meters in security models (and more than 300 meters in some outdoor speakers). There is a fair amount of data loss can wooden degradation of the audio signal, resulting in poor image quality. Conflicting signals from other wireless devices in the home, etc. as wireless routers, cordless phones can cause interference, leading to data loss and disruption. Altogether, RF, despite its popularity, Feb. ask phased out over the next few years as newer technologies take place.


If you bought a new mobile phone in the past two years, you would definitely be familiar with Bluetooth. If a wireless data standard that is used in almost any mobile phone, Bluetooth is ubiquitous These Days. Through this technology two Bluetooth devices can be connected wirelessly within seconds. Once a connection is established, data can be transmitted wirelessly, that speeds of up to 3 MB / second.

technology, Bluetooth operates on the radio spectrum as well. Instead of overuse of a single band, however, Bluetooth chops up the data and distributes it over 79 different bands, improving the speed and reducing data loss. These two bands range from 2400 MHz 2483.5 MHz.

Bluetooth has a smaller range than pure RF signals. On the positive side, because the entire 2400-2483.5 MHz spectrum (79 bands, alongwith save guard bands) allocated for the use of Bluetooth, there is no interference from other wireless devices.

A major problem with Bluetooth Is that not in all establishments. Older phones, most audio and video players, TVs and desktop computers are not equipped with native Bluetooth. Two use a pair of wireless Bluetooth speakers with these devices, you two have invested in a Bluetooth transmitter. However, if you use a Bluetooth device Mainly ed as an iPhone or iPod Touch two list to your music, you’ll Bluetooth wireless speakers to a competent competitor are two RF.


Only a select number of speakers to use Wi-Fi to send data – ed as the Sonos Play series speakers. This is the same plain vanilla exceptional WiFi in your home. It is fast and efficient and works well with digital, Wi-Fi devices such as computers and mobile phones.

However, most audio players, televisions, etc. Are not using Wi-Fi. This meansthat a Wi-Fi wireless speaker can only play audio from your computer or mobile phone. Obviously this limits the functionality and ice the only reason why the Wi-Fi wireless speakers include taxes and booking accepted by the mainstream.
