How Wireless Home Audio Speakers Work
Wireless Home Audio Speakers allow you to have surround sound anywhere you want it, without any strings attached. Wireless technology has been under some serious development and lot of progress has been made in this area. As a result of that, the prices are dropping while the quality is improving. The sound quality is increasing, the coverage area is also increasing. The best thing about Wireless Home Audio Speakers is they can be setup in just a couple of minutes. All you have to do is connect the transmitter to the sound source - hi fi or computer, and then power up the speakers. Once you have done that, turn the system on and simply enjoy the sound. The majority of models operate on 900MHz frequency, although certain models work on up to 5.4GHz. The higher the frequency the bigger the coverage and on top of that, the signal is stronger so it can go through different obstacles.
What you should keep in mind is that although there are some serious improvements in this technology, the word 'wireless' doesn't mean completely wireless. You still have to power the speakers somehow and this can only be done with some hard wiring. The technology is no that advancement so that we can power up devices remotely. Each speaker is equipped with an AC adaptor that has to be connected to the power source. And there is another small wiring involved as the transmitter has to be connected the sound system, whether it's hi-fi or PC. Fully wireless home audio speakers are still not a true mass-market possibility. So fact is that audio and video interconnects will still be used for years to come. The biggest problems ahead of manufacturers of wireless home audio speakers are quality, pricing and security. Most models work on 900MHz frequency. This is the frequency at which the transmitter sends the sound signal to the speakers. Usually, one transmitter is able to work with just a couple of speakers although there are models that can handle four. The connection between the transmitter and the sound system is done with a normal speaker wire. There are some models that work in the 5GHz range, which means that the cover is seriously increased. With a 900MHz band, the signal can travel up to 300 feet, after that it gets way too distorted. But with 5.4GHz, the signal can go even further and be sharper. |
