A Glance At A Few Of The Newest Wireless Toys
Lately a large number of wireless audio products have appeared such as latest-generation wireless headphones, iPods, cell phones and wireless amplifier products which claim to eliminate the cord. I will have a look at a number of the latest devices and technologies to see how well they work and in which conditions they operate best.
Products can be categorized into products with built-in and those with optional wireless functionality. Streaming audio products will often have a plug-in slot for adding a wireless LAN card. Modern cell phones and MP3 players already come with support for wireless. iPhones and touch-screen iPods, as an example, have Bluetooth and WiFi.
Bluetooth is fairly common as a low-cost wireless option. Still, Bluetooth does have some limitations. These weaknesses are frequently ignored but will have an impact on high-quality audio applications.
1) Restricted range
The range of Bluetooth devices is generally merely 30 ft. This excludes Bluetooth from multi-room applications.
2) Audio compression due to limited data rate
Bluetooth reliably supports data transmission rates of about 1 Mbps only which is not sufficient for uncompressed CD-quality audio. Thus Bluetooth applies audio compression. The audio will be degraded to some extent because of the audio compression. For this reason higher-end audio equipment generally does not use Bluetooth wireless audio.
3) Audio delay
The signal broadcast via Bluetooth will bear a slight delay of a minimum of 10 ms. This is mostly as a result of the audio compression. While being uncritical for MP3 players, this delay may be a dilemma for video and other real-time applications.
4) No support of multiple headphones
Bluetooth does not support any number of headphones which might be a dilemma if you have a larger number of people who want to listen to headphones from a single transmitter device.
WiFi is an additional widely used wireless protocol that is also suitable for audio streaming. WiFi does support uncompressed audio but will have problems transmitting to a high number of wireless receivers at the same time. As a result of the high availability, WiFi is convenient for streaming audio from a PC. However, WiFi products have relatively high power consumption. Because of this wireless headphones usually do not use this technology.
Home wireless speaker devices and wireless amplifiers usually employ proprietary protocols. These protocols are specially designed for real-time audio applications. Yet, low-cost wireless speakers and headphones still employ FM transmission. FM transmission suffers from rather high audio deterioration and hiss / static.
More recent wireless audio protocols are based on digital transmission. This eliminates audio degradation. A few protocols also incorporate error correction to deal with interference from other wireless products.
Sophisticated wireless amplifier products support uncompressed digital audio streaming to preserve the original audio quality. Some of these protocols permit streaming to an infinite number of wireless amplifiers which is practical for whole-house audio distribution.
Some of these protocols support low-latency audio transmission which ensures that the audio of all speakers will be in sync in a multi-channel application. These wireless audio transmitters generally work at 2.4 GHz. There are also some devices including Amphony’s line of wireless audio devices which operate at 5.8 GHz. Products that work at 5.8 GHz have less competition from other wireless products than those using the crowded 2.4 GHz frequency band.
These wireless amplifiers also differ regarding amplifier output power, standby power consumption and audio quality. A high-quality audio amplifier is essential for optimal sound quality. Digital Class-D amplifiers offer high power efficiency of at least 80%. They also have low standby power, usually less than 5 Watts. This minimizes heat and keeps them cool during operation. Some digital amplifiers, on the other hand, have fairly high harmonic distortion. Audiophile wireless amplifiers offer an audio distortion of 0.05% or less.
