802.11n Capacity
802.11n offers major increases in capacity over prev
ious 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).

802.11 Mode # Channels Max Theoretical Capacity
Fast Ethernet No Yes
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
