The 50S’ Mesh technology brings a new level of robust, reliable connections and smart, flexible intercom message routing thanks to significant technical enhancements made to the original Sena Mesh Intercom™ algorithm. Sena’s 50S units actively share information between each other within the Mesh network at an astounding rate. An ingenious system of prompts and responses between the Mesh units has resulted in 80% more data being transferred across challenging and harsh conditions. Furthermore, Mesh units quickly determine the ideal pathway to efficiently transmit messages from rider to rider.

Sena’s Mesh technology offers an unprecedented level of intercom audio quality and robust connectivity for all Sena Mesh Intercom™ users. Tested and proven in the most demanding situations, Sena’s Mesh network keeps the communication lines with your riding partners clear and stable..


The 50S delivers not one, but three different intercom modes available to Sena riders: Multi-Channel Open Mesh Intercom™, Group Mesh Intercom™, and Bluetooth® Intercom.

Multi-Channel Open Mesh Intercom (Open Mesh) features the industry’s first Mesh Intercom™ channel system. Similar to standard handheld or CB radios, the 50S allows users to switch between nine different channels when operating in Open Mesh mode. Open Mesh offers a single push of a button to click-to-connect to the Mesh Intercom™ network. 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). With this ease of connecting, huge user capacity, incredible range, AND the inclusion of the nine-channel feature, the 50S Open Mesh Intercom mode is sure to be a game-changer for large group/club rides.
