There are only 3 main frequency bands in which current wireless loudspeakers operate: 900 MHz, 2.4 GHz and 5.8 GHz. Rising competition in these frequency bands has led makers to invent completely new techniques that can manage the higher interference, one of these I'll show you in this post.

Increasing competition in these frequency bands has led suppliers to invent new methods that are able to deal with the higher interference, one of which I will demonstrate in the following paragraphs.
