MXP660 Portable Two-Way Radio

Working with end users, Designers identified the following challenges: -Develop a wearable, compact device able to deliver clear voice communication in a variety of harsh environmental conditions. -Provide a simple interface to reduce user/device distraction and improve situational focus. -Automatically maintain communication, in situations where default TETRA network coverage is absent, without requiring user input. -Optimize audio performance to reduce background noise, assure call clarity/context, and improve speech intelligibility. -Enable simple and secure collaboration with smartphones, tablets, body cameras, and audio accessories. -Maintain compatibility with existing charging, battery, and audio accessories to optimize organization’s budgetary constraints.

The MXP660 solution provides a simple interface reducing user/device distraction and improving situational focus. The emergency button is large and easy to operate, yet well protected from accidental activation. A tactile glove-friendly push-to-talk (PTT) button along with three programmable side buttons allow users to activate frequently used functions. If there is no TETRA coverage the MXP660 automatically switches to an available broadband connection via LTE or Wi-Fi, which connects the user back to the TETRA network. This switchover requires no user intervention while providing uninterrupted connection to ensure awareness and safety.

Consistent, accurate, and instant communication is vital for first responder success when managing incidents. MXP660 allows users to focus more on people and tasks and less on their tools as they are now able to communicate automatically across networks without the need to manage switchovers or worry about coverage. The compact size and purpose-built controls also provide users with the functionality they require without overwhelming them with complexity. This project helped designers and researchers identify specific concerns in the everyday workflows of users and address them in order to improve personal and societal safety.

-Artificial Intelligence (AI) technology is used to enhance noise suppression. Microphone audio is processed by the radio, transmitting the user’s voice while suppressing other sounds such as sirens, crowd noise, wind noise and machinery. The result is significantly improved voice call clarity and intelligibility, even with extreme background noise. -Location Precision: If an emergency button or Fall Alert feature has been activated on the MXP660, it enables dispatchers to pass on accurate location information to others on the front line, allowing help to arrive faster. -Frontline personnel often work in conditions where it’s not convenient to detach and operate a radio, or covert scenarios where having a radio on display might not be desirable. For these situations, MXP660 securely pairs with a smartphone or tablet over Bluetooth and is controlled with a collaborative radio control app. -Tested to military standards MXP660 can withstand drops from 1.2 meters to a hard floor. With IP65-68 (2 m, 2 h) ratings, the device resists dust, dirt, heavy rain, jets of water and submersion in 2 meters of water for 2 hours.
