cordless advanced technology - internet and quality (CAT-iq)

With Cordless Advanced Technology- Internet and Quality (CAT-iq), the DECT Forum has developed a standard for in-house communication based on Digital Enhanced Cordless Telecommunications (DECT). CAT-iq improves voice quality

and at the same time incorporates IP communication. CAT-iq can also beused




such as

thecontrol of home automation systems


the transmission


switching commands or sensor values


The transmission uses Gaussian Minimum Shift Keying (GMSK) modulation with a data rate of 1.152 Mbit/s

.CAT-iq uses the same frequency range between 1.880 GHz

and 1.990 GHz as the DECT standard. This frequency range has the advantage of not being affected by Bluetooth or WLANs

. As for the CAT-iq standard, the European Telecommunications Standards Institute (ETSI) is working on different versions for voice and data communications:

  • CAT-iq 1.0 "HD Sound": ETSI TS 102 527-1, broadband voice transmission,
  • CAT-iq 2.0 "Multi Line": ETSI TS 102 527-3, enhanced broadband voice services,
  • CAT-iq 2.1"Green": ETSI TS 102 527-5, RF power control, power saving modes,
  • CAT-iq 3.0 "Internet Ready": ETSI TS 102 527-4, software update services and HTTP based applications,
  • CAT-iq 4.0 "Intelligent Networking".
