Figure 3-3 SCALANCE IWLAN 802.11n AP’s Baseband
Figure 3-3 illustrates the following:
• The SCALANCE IWLAN 802.11n AP has two radios — Radio 1 and Radio 2.
• Radio 1 supports the 5 GHz radio, with radio modes a, a/n, and n-strict.
• Radio 2 supports the 2.4 GHz radio, with radio modes b, g, b/g, b/n, b/g/n, and n-strict.
• Radio 1 is connected to external antennas R1A1, R1A2, R1A3, and Radio 2 is connected to
external antennas R2A1, R2A2, R2A3.
5 GHz radio supporting the 802.11a/n standard — When in legacy 802.11a mode, the SCALANCE
IWLAN 802.1n AP supports data rates up to 54Mbps. The modulation used is OFDM. In 802.11n
mode there are two supported channel bandwidths, 20MHz and 40MHz. The 802.11n AP supports
up to 450Mbps in 40MHz channels and 216Mbps in 20MHz channels. The modulation used is
MIMO-OFDM with one or two spatial streams.
2.4 GHz radio supporting the 802.11b/g/n standard — When in legacy 802.11b/g mode, the
802.11n APs support data rates up to 54Mbps, identical to the Standard APs. The modulation used
is OFDM for 11g and CCK for 11b. In 802.11n mode there are two supported channel bandwidths,
20MHz and 40MHz. The 802.11n APs support up to 450Mbps in 40MHz channels and 216Mbps in
20MHz channels. The modulation used is MIMO-OFDM with up to threespatial streams.
