The New Generation DECT (NG-DECT) standard, marketed as [[CAT-iq]] by the DECT Forum, provides a common set of advanced capabilities for handsets and base stations. CAT-iq allows interchangeability across [[IP-DECT]] base stations and handsets from different manufacturers, while maintaining backward compatibility with GAP equipment. It also requires mandatory support for [[wideband audio]].

DECT-2020 New Radio protocol was published in July 2020; it defines a new physical interface based on [[Cyclic Prefix]] Orthogonal Frequency-Division Multiplexing (CP-[[OFDM]]) capable of up to 1.2{{nbsp}}Gbit/s transfer rate with [[QAM]]-1024 modulation. The updated standard supports multi-antenna [[MIMO]] and [[beamforming]], FEC [[channel coding]], and hybrid [[automatic repeat request]]. There are 17 radio channel frequencies in the range from 450 MHz up to 5 875 MHz, and channel bandwidths of 1728, 3456, or 6912 kHz. Direct communication between end devices is possible with a [[mesh network]] topology.
