802.11n Capacity
802.11n offers major increases in capacity over previous 802.11 standards, as
shown in the table below.
Failover Planning
This section discusses failover protection at the unit and port levels.
To ensure that service is continued in the event of a port failure, you can utilize
two Gigabit Ethernet ports simultaneously as a bonded pair (on Arrays with two
or more Gigabit ports).
Figure 25. Port Failover Protection
802.11 Mode # Channels Max Theoretical Capacity
802.11 a/n: 3 Streams 23 23 * 450 Mbps = 10.2 Gbps
802.11 a/n: 2 Streams 23 23 * 300 Mbps = 6.8 Gbps
802.11 a/n: 1 Stream 23 23 * 150 Mbps = 3.4 Gbps
802.11 a 23 23 * 54 Mbps = 1.2 Gbps
802.11 g/n: 3 Streams 3 3 * 450 Mbps = 1.35 Gbps
(1 or 2 streams have
proportionally lower capacity)
802.11 g 3 3 * 54 Mbps = 162 Mbps
802.11 b 3 3 * 11 Mbps = 33 Mbps
