Sealed in plastic never used 30K operates on Sena’s Mesh Intercom technology, a 2.4 GHz frequency, connecting to other riders in an entirely new way. Group connectivity is made simple with the 30K. Should one of the group’s riders go out of range, the Mesh Intercom intelligently keeps the rest of the group in seamless communication, while actively searching to reconnect, should that rider come back within range. Never again will you have to stop and reconnect two antennae and two separate and dedicated processors, the Sena 30K is both a 4.1 Bluetooth headset and an Adaptive Mesh-Networking device full duplex communication with up to 16 riders at a range up of to 1.2 miles, while an endless amount of additional Guest users can tune in for listening only. When riding with 5 or more riders, the Mesh Intercom is capable of keeping the group connected at a range of up to 5 miles Built-in FM radio with RDS AF 30K is still capable of pairing with up to 3 other Sena or non-Sena Bluetooth communicators at a range of up to 1 mile Audio Multitasking technology allows you to have a conversation via Adaptive Mesh-Networking technology while simultaneously enjoying Bluetooth operations such as streaming smartphone music, taking or making phone calls, or listening to turn-by-turn GPS navigation
