With multiple link
profiles, the wireless
network performance
is getting affected.
The overall performance of the wireless network gets affected when using multiple link
profiles and atleast one of the subscriber is operating with a lower data rate.
For example, consider a wireless network with a BSU and 5 SU profiles. Each SU is
transmitting data at a data rate as tabulated below. As SU1 is operating at a lower data
rate (6.5 Mbps), the entire performance of the network gets affected.
In order to optimize the network performance, apply QoS.
Given below is an example on how the network performance can be improved by applying
QoS. QoS is applied for SU1 with the following configuration:
`
PIR based on the ToS value 96
`
SFC with MIR/CIR= 1Mbps; Priority = 3; Latency/Jitter=10ms
Subscribers SU2...SU5 use the default QoS configuration.
: Given above is just an example and values might vary from case-to-case.
Reason(s) Observation
SU Profile(s) Data Rate Throughput
SU1 6.5 Mbps
Aggregated
throughput can be a
maximum of 13 Mbps
SU2 39 Mbps
SU3 78 Mbps
SU4 130 Mbps
SU5 78 Mbps
Profiles Data Rate Throughput
SU1 6.5 Mbps
With QoS applied for
SU1, expected
throughput is 26 Mbps
SU2 39 Mbps
SU3 78 Mbps
SU4 130 Mbps
SU5 78 Mbps
