Siemens Home And Office Communications Devices is planning to deliver an array of cordless phones based on DECT (Digital Enhanced Cordless Telephony) standards.
DECT is a relatively new cordless telephony standard in the United States, but it has been around for more than 10 years in Europe. Unlike Wi-Fi, which operates in unlicensed frequencies in the 2.4-GHz and 5-GHz bands, DECT operates in a licensed band (1,920 MHz to 1,930 MHz) free from call quality-damaging interference. Siemens product announcements signal a significant push from this German-based vendor to provide an alterative to Vo-Fi (voice over Wi-Fi)--particularly in the home. The Vo-Fi deployment problems in the enterprise--poor coverage, interference and a short battery life--are nonissues for DECT-based products.
