R&S®SMW-K86 IEEE 802.11ac Digital Standard

• Support of all 11 ac transmission modes with R&S^®SMW-K86 option (VHT-20 MHz, VHT-40 MHz, VHT-80 MHz, VHT-80+80 MHz, VHT-160 MHz)
• Support of all three operating modes (legacy, mixed mode, green field)
• Support of space time block coding (STBC) and spatial multiplexing
• Up to eight spatial streams in all supported channel widths
• MIMO modes with up to eight transmit antennas
• Simulation of realtime MIMO channel condition for instruments equipped with the R&S^®SMW-B14 (2x or 4x)/R&S^®SMW-K74 fading options
• Multi-user MIMO available with two or more total spatial streams
• Configurable number of spatial streams, space time streams and additional spatial streams, as well as configurable modulation per spatial stream
• BPSK, QPSK, 16QAM, 64QAM and 256QAM modulation
• Support of long or short guard interval
• BCC and LDPC channel coding
• Configurable state of the scrambler, interleaver, time domain windowing and channel coding
• Configurable PPDU, MAC header and FCS
• Data, sounding or beacon frames
• Integrated frame block sequencer for generating a sequence of cascaded frame blocks with different WLAN modes, configurations and data rates
• Support of simple diversity and static MIMO tests without additional channel simulator

IEEE 802.11ac -further extends 802.11n to nominal peak data rates of 6240.0 Mbps. Like IEEE 802.11a/g/n, IEEE 802.11ac is based on OFDM. Additionally, IEEE 802.11ac uses MIMO technology, up to 160 MHz bandwidth and special coding for increased throughput. The extension towards higher data rates is also known as very high throughput (VHT) mode of 802.11ac.

The R&S^®SMW-K86 option extends the R&S^®SMW-K54 option to support physical layer signal generation in line with the IEEE 802.11ac standard.
