One of Sonos’ strength is its proprietary grid network where at least one component is wired to the network and the remaining units form a wireless grid around the wired ones. The grid is stable but also contributes to radio wave pollution in the home. Now Sonos have updated their software to allow components to connect to an existing wireless network without the leash. The obvious advantage of this new update is that the Bridge in many cases will be obsolete. Should you wish to, however, you can still wire as many components as you wish and thus increase stability. In fact the Bridge will still be available in the future.
It may sound strange then, that they will be releasing a new bridge in October. The Sonos Boost. This will be a more powerful version of the Bridge and should be a welcome addition to setups where wifi quality is hampered by large distances or thick walls.
