Secure Wireless Communications — with 900MHz (902~928MHz) FHSS (Frequency Hopping Spread Spectrum) technology.

The DuraFon-SIP is not a multi-base system. If more than one base is used, they need to be > 30 feet apart to avoid self-interference; the 2-Way Intercom and "Push-to-Talk" features will not work across Handsets registered to different bases.
