9. Yealink Repeater RT30
Yealink DECT Repeater RT30. DECT Repeater. Compatible with Yealink W60B, W70B, and W52 DECT IP base stations. Up to 6 repeaters per base station (star configuration), up to 2 repeaters can be arranged in a cascade. Plug & Play setup. Clear LED status indicator. Elegant design, wall mounting possible.
The Yealink DECT Repeater RT30 is designed according to the Digital Enhanced Cordless Telecommunications (DECT) standard and features easy installation and a user-friendly display concept. The repeater can be used to significantly extend the DECT radio coverage of the Yealink W60B and W70B base stations in all directions. When working with the W60B or W70B, it supports two cascaded RT30 units. Clear LED indicators are used to distinguish various DECT statuses.
Additionally, the elegant design and straightforward installation make it particularly suitable for use in modern business environments. The device operates with DECT technology: utilize the wireless connection and move up to 50 meters away from the base station while talking indoors. Since the technology operates below 2.45 GHz, it uses different frequency ranges than Wi-Fi or Bluetooth, ensuring it does not interfere with these networks. Switching the base station within a multi-cell radio network is possible by forwarding to another cell.

10. Gigaset Repeater HX
More range for DECT phones
The new Gigaset Repeater HX doubles the DECT range of Gigaset base stations, enabling uninterrupted calls in perfect sound quality across multiple floors and spacious areas.
Prepared for the future
The additional implementation of the CAT-iq standard, as seen in all Gigaset HX universal handsets, ensures compatibility with DECT/CAT-iq routers that support the new ETSI Repeater Standard (ETS300700 V2.1.1). This makes the Gigaset Repeater HX ready for future generations of routers.
Features for enhanced security
With the new Early Encryption feature, encryption occurs before each call is transmitted. This ensures a particularly high security standard for telephony at work or at home. The Re-Keying function—changing the session key or encryption key during an ongoing communication—also enhances data security. The Gigaset Repeater HX continuously modulates the security key even during a call. Additionally, the device supports software updates via over-the-air interface (SUOTA). Thanks to these technologies, the Gigaset Repeater HX meets the current standards of the European Telecommunications Institute.
