The ESI Cordless Handset II uses advanced DECT 6.0 third-generation 1.9 GHz technology to provide mobility to the user who’s constantly on the move in the office. Like the original ESI Cordless Handset models, each ESI Cordless Handset II provides its user most of the rich ESI feature set along with the convenience of a portable device – with the added benefit of increased range of use, thanks to DECT’s ability to support repeaters. This lets users continue calls while moving between different coverage cells throughout a location, using a process known as handoff that’s similar to how cell phones work. When you return to your desk, a touch of ESI’s Quick Switch™ Key lets you toggle from the lightweight, portable Cordless Handset II back to your full-function ESI desktop phone.

Under DECT 6.0, each ESI Cordless Handset II operates on the 1.9 GHz frequency band, which has been specially allocated to support cordless telephony. Benefits of DECT 6.0 technology include:
- Longer battery life (including longer standby time).
- Support for Repeaters – Each base unit can be expanded to support up to six optional ESI Cordless Handset II Repeaters (see diagram, below). This enables the user to significantly extend telephony coverage as compared to a traditional cordless telephone, by simply installing Repeaters in appropriate locations. (For details concerning Repeater use for your facility, please contact your Certified ESI Reseller.)
- Encrypted radio traffic for higher call security.
- Wi-Fi friendliness — DECT 6.0 technology enables use of ESI Cordless Handsets II within range of wireless home networking (or WLAN) systems without interference, a major advantage in the many businesses that also make use of WLANs.
