Many home owners have started to use wireless surround sound kits to connect rear home theater speakers. These kits are a great choice for situations where it is difficult or impossible to run long speaker wire. These kits essentially replace the speaker cord by a wireless signal. However, the big question for many people considering purchasing a wireless speaker kit is: how reliably do those kits work? In this post I will look at some of the techniques that manufacturers of these kits use to achieve high reliability of the wireless transmission.
The main problem facing wireless audio kits is wireless interference. Interference is generated by other wireless transmitters that occupy the same frequency band. As a result, there can be collisions between the signal from another transmitter and the own signal. A collision can cause a data packet to be dropped. If a data packet is lost or damaged the audio signal cannot be generated due to missing data. As such, manufacturers of wireless surround sound models shown at www.amphony.com/products/wireless-surround-sound.htm have come up with several techniques to combat interference. The most commonly used methods include error correction and packet retransmits. Using those techniques wireless speaker kits achieve surprisingly high reliability.
