For details about calculation equations, see "Network bandwidth" (page 21) in the "Active
Learning" section.
Network bandwidth that the wireless LAN access point must maintain
Calculation equation
Required bandwidth (T
× Number of Pods
+ Total throughput of user devices connected to main unit
= (6 Mbps × 1 + 1 Mbps × 5) × 10
+ (6 Mbps × 2 + 1 Mbps × 4)
= 126 Mbps
Adding the margin of 30%, 126 Mbps × 1.3＝163.8 Mbps
Network bandwidth that must be maintained between each Pod and layer 2 switch
Refer to "Network bandwidth that must be maintained between each Pod and layer 2 switch"
(page 37) in the "Small-scale 3-Pod configuration" section.
Network bandwidth that must be maintained between main unit and layer 2 switch
Calculation equation
Required bandwidth (T
+ Total throughput from Pods to main unit
+ Total throughput from main unit to Pods
+ Total for video conferencing
+ Streaming output
= (6 Mbps × 2 + 1 Mbps × 4)
+ (6 Mbps × 0 + 1 Mbps × 10)
+ (6 Mbps × 10)
+ (4 Mbps + 4 Mbps)
+ 6 Mbps
= 100 Mbps
Adding the margin of 30%, 100 Mbps × 1.3＝130 Mbps
Note that if a presentation is predominantly composed of still images, the throughput will be
lower and hence the required bandwidth will also be lower. Estimate the network bandwidth to
match the intended use.
