Within the Wi-Fi world, I find myself constantly referring to the MCS Index. DECT-NR+ is still very much an emerging wireless protocol, and such resources have not yet been created. MCS tables are used to help determine potential data rates in different circumstances

The MCS Index for DECT-NR+ can be accessed via this link, which will redirect you to a google sheet.


The document contains the data rates for the 3 full carrier transmissions. Per the standard, it is possible to send a half carrier transmission, or even to bundle several full carrier transmissions. Based on my experience, this is yet to be implemented in the stacks today. In fact, only 2 of the full carrier transmission channel widths seem to be supported by the available chipsets on the market.

Additionally, typically we are working with 1 spatial stream. The MCS Index document covers up to 6 spatial streams for completeness.

The following variables are considered when calculating MCS for DECT-NR+:

  • R: Code rate
  • NBPSC: Number of bits per subcarrier
  • NSD: Number of data subcarriers per OFDM Symbol
  • NSP: Number of pilot subcarriers per OFDM Symbol
  • NCBPS: Number of coded bits per symbolNDBPS: Number of data bits per symbol
  • Spatial Streams
  • Channel width

The data presented to you inside this document has been compiled from different sources available from the ETSI website.

DECT-NR+, the first non-cellular 5G protocols is a cluster tree mesh operating in the DECT frequencies. It is an emerging wireless technology, promoted mainly by Wirepas and Nordic Semiconductors.
