Wearable Digital Communicator
Rollts Domino R1
Repeater
Extends communication range of Rollts Digital
Communicator and builds a small-scale
communication network
900 MHz / *(EU) 800 MHz ISM license-free band
Frequency Hopping Spread Spectrum (FHSS)
Resistant to narrowband interference and difficult to intercept
Uses bandwidth more efficiently
Main Power Supply and High-Capacity Battery
12V DC power adapter and 20,000 mAh rechargeable battery lasts up to 3 days
Possible for both portable and fixed use with two-way power supply
Encryption (AES-256)
Making eavesdropping impossible, even when set to the same channel and group using
encryption technology
High receiving sensitivity
Receives weak signal and transmits it with high-quality communication signal
Only Rollts makes possible.
Eliminates indoor communication blind spots
Extends the communication range infinitely through relay among Rollts Digital
Communicators and Repeaters
Secures own local communication network by building a small-scale
communication network
Supports for both portable and fixed use outdoors and indoors
