R&S®SMBV-K142 IEEE 802.11ax Digital Standard

  • Overview

Key facts

  • Guard interval duration: 0.8 µs, 1.6 µs or 3.2 µs
  • OFDM symbol duration: 3.2 µs, 6.4 µs or 12.8 µs
  • Support for MCS0 to MCS11
  • Extended range preamble and MCS0 rep2

Brief description

IEEE 802.11ax extends 802.11n to nominal peak data rates of 9607.8 Mbps. Like IEEE 802.11a/g/n, IEEE 802.11ax is based on OFDM. Additionally, IEEE 802.11ax supports two new modulation and coding schemes (MCS 10 and 11) with 1024QAM increased throughput.

Key facts

  • Guard interval duration: 0.8 µs, 1.6 µs or 3.2 µs
  • OFDM symbol duration: 3.2 µs, 6.4 µs or 12.8 µs
  • Support for MCS0 to MCS11
  • Extended range preamble and MCS0 rep2
  • Multi-user MIMO in uplink and downlink
  • BCC and LDPC channel coding
  • Support for space time block coding (STBC) and spatial multiplexing
  • Up to eight spatial streams in all supported channel widths
  • Configurable number of spatial streams, space time streams and additional spatial streams, as well as configurable modulation per spatial stream
  • Configurable state of the scrambler, interleaver, time domain windowing and channel coding
  • Configurable PPDU, MAC header and FCS

Brief description

IEEE 802.11ax extends 802.11n to nominal peak data rates of 9607.8 Mbps. Like IEEE 802.11a/g/n, IEEE 802.11ax is based on OFDM. Additionally, IEEE 802.11ax supports two new modulation and coding schemes (MCS 10 and 11) with 1024QAM increased throughput.

To improve the capabilities in outdoor environments, the symbol duration is extended by factor 4 to increase the robustness and a new extended range preamble to increase the operational range.
