Brief Description The R&S®SMW-K54 option for the R&S®SMW200A generates physical layer signals in line with the IEEE  802.11a/b/g/n/j/p standard. In the OFDM modes, all data rates of the IEEE 802.11a and IEEE 802.11g standards from 6 Mbps to 54 Mbps, as well as data rates from 3 Mbps to 27 Mbps of IEEE 802.11j and 802.11p are supported. The same is true for the CCK mode with data rates from 1 Mbps to 11 Mbps, as well as for the PBCC mode, where an optional expansion with data rates up to 22 Mbps has been added to the IEEE 802.11b standard. For 802.11n, channel bandwidths of 20 MHz and 40 MHz are supported. The option supports high throughput (HT) mode and includes MIMO capabilities (generation of one to four spatial streams, one to four TX antennas).''
