Tips for Increasing the Wireless Range of Audio Transmitters

Audio transmitters are in neat type of product for streaming audio between two locations without running long cables. They have become more popular with the introduction of reliable digital transmission technologies. However, these digital technologies have certain limitations when it comes to wireless range. In contrast to analog audio transmitters, digital products typically work perfectly within a certain range and then drop the signal completely.

However, there might be situations where you want to transmit from one location to a location that is far away. For example, transmitting to multiple rooms in your house poses a challenge is products. That is because the wireless signal will have to traverse walls. When traversing walls, the signal is attenuated which means that the actual range will decrease rapidly. Chances are that you will not be able to transmit to the location that you had in mind.

Therefore, you might want to consider some of these options which I’m discussing in the next few paragraphs in order to achieve the desired operating range.

First of all, I recommend experimenting with directional antennae. These antennae will transmit the signal primarily towards one direction. That means that rather than dissipating the energy into all directions, it will focus the signal into one specific direction. You can Mount these antennae both on to the transmitter as well as the audio receiver. Then rotate both antennae such that they main beam of each antenna is facing towards one another.

If you still don’t have sufficient range you might need a repeater. A repeater a wireless transmitter and receiver which picks up the signal from the transmitter and re-sense it. By using a repeater, you can typically double the wireless range. The repeater should be located somewhere in between the transmitter and receiver. However, if they are particularly many walls on one side of the transmission then you might want to locate the repeater closer towards that side. A larger number of walls will attenuate the signal more.
