1. 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 found 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 means the Gigaset Repeater HX is 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. Additionally, the Re-Keying function—changing the session key or encryption key during an ongoing communication—provides extra data security. The Gigaset Repeater HX continuously modulates the security key even during a call. The device also supports software updates via Over-The-Air (SUOTA). Thanks to these technologies, the Gigaset Repeater HX meets the current standards set by the European Telecommunications Institute.
