MESH & BLUETOOTH® INTERCOM

The SRL-EXT offers both Mesh Intercom™ and traditional 4-way Bluetooth® intercom, allowing for compatibility with any Sena or Sena-powered device. Sena’s industry-leading Mesh Intercom™ communication platform has two modes: Multi-Channel Open Mesh Intercom™ (Open Mesh) and Group Mesh Intercom™.

Open Mesh offers a single push of a button to click-to-connect to the Mesh Intercom™ network and features the industry’s first Mesh Intercom™ channel system. Like standard handheld or CB radios, Open Mesh lets users switch between 6 channels. It also supports a near-limitless number of users within a range of up to 5 miles / 8 km (min. 6 riders @ 1 mi / 1.6 km intervals).

Group Mesh supports a single, private group for up to 24 participants and the same range as Open Mesh for a more intimate group conversation. Only invited users can join the Group Mesh chat. Open Mesh and Group Mesh provide unprecedented intercom audio quality and robust connectivity.
