BR688 is the latest portable digital repeater. The compact and exquisite design can flexibly adapt to various environments by backpack, wall-mounting, and pole mounting, etc. It has made further breakthroughs in performance, appearance and functionality, effectively guaranteeing stable and reliable communication and enhancing users cope with challenges in actual work.

Digital/Analog Compatible
BR688 is fully compatible with PDT and DMR digital handheld terminals, and supports analog, digital, and analog/digital auto-mixed operation modes, thereby providing users with greater flexibility in the selection of communication terminals.

AI Noise Reduction
BR688 portable digital repeater is equipped with the most advanced AI noise reduction algorithm, which can filter the background noise and upgrade the signal-to-noise ratio of audio communication. In addition, it can suppress the echo of the short-range communication, effectively reduce the howling, and minimize the interference caused by short-range communication.

*IP Interconnection Networking
BR688, as a same frequency repeater, supports IP interconnection networking between up to four devices, providing users with powerful and stable network communication signal coverage in each workplace. In addition, it can also establish IP interconnection networking with other BelFone Repeater models, realizing the devices’ utilization.

Management and Dispatching Visualization
BR688 supports access to the BelFone SDC system, realizing voice dispatching, GIS dispatching, data management, and personnel management, etc. It provides intelligent support for visual command and dispatch.

Super Long Battery Life
BR688 can be equipped with an optional 5000 mAh high-capacity battery for outdoor use, providing up to 8 hours of power supply at 10W RF output, ensuring uninterrupted communication for users.

Single-Frequency Repeater
BR688 with its single frequency repeater functions to expand communication coverage while effectively saving frequency resources, so that users can establish a same-frequency network rapidly. It not only saves frequency points but also saves terminal programming time, improving dispatching efficiency.

Floating Charging Mode
BR688 supports battery charging and external DC charging mode. The external DC power supply will provide the floating charging for the battery, ensuring the lithium is fully charged. If the external DC power supply is accidentally interrupted, the battery will automatically take over and provide power for the Repeater to ensure the normal operation of the equipment. This backup solution reduces the capital investment and maintenance manpower required for UPS power equipment, ensuring long-term communication reliability.

Advanced Digital Encryptions
BR688 supports XOR encryption and can optionally AES256 and ARC4 advanced encryption. Turning on the encryption function encrypts the voice and data sent on the current channel to ensure voice and data security. This improves communication security and provides privacy and information security protection.

Rugged and Durable
BR688 portable digital repeater is made of aluminum alloy and complies with IP68 protection. Its excellent rugged design guarantees stable and outstanding performance even when exposed to harsh environments.
