6.3.6.1
Understanding Received Signal Strength
Received signal strength (RSSI) is measured from connected wireless client devices to
the UBC1301-AA00. This value can significantly impact wireless speeds/performance. It is
determined by:
Materials (for example, open air, concrete, trees)
Distance between wireless clients and the wireless cable modem
Wireless capabilities of the client devices
6.3.6.2
Estimating Wireless Cable Modem to Wireless Client Distances
The information in this section helps you to determine how far a wireless cable modem
can be placed from wireless client devices. Environmental variances include the
capabilities of wireless clients and the types of material through which the wireless signal
must pass. When the wireless cable modem and wireless clients reach the distance
threshold between each other, network performance degrades.
To determine wireless gateway placement:
PS Pretend
Retry Limit
Allows you to set the PS (Power Save) Pretend Retry Limit. Many times we consider that packet
loss is due to a momentary problem that will resolve itself. PS pretend refers to the mechanism
when we “pretend” that during a time period, the wireless station is doing power save. During this
period, we stop sending traffic to this station and failing packets are recovered and saved to the
power save queue. The retry limit is the number of times to do successive PS Pretend. The typically
suggested value is around 5. In some cases, high values (10 or more) may be beneficial. A value of
zero means the feature is disabled.
PS Pretend
Threshold
Allows you to set the PS (Power Save) Pretend Threshold. PS pretend does not activate
immediately on the first loss in threshold mode when a successive count of transmission failure
reaches the threshold, then PS pretend activates. The packets prior to hitting the thresholds are
lost. This offers a fix for dead link problems in multilink once the threshold is hit. With a value of 0 it
is disabled. The suggested value is 5 or 10.
ACS Mode
Allows you to set the ACS (Auto Channel Selection) mode. Options are:
SCA: Stable Channel Switching
FCS: Fast Channel Switching
Apply/Save
Applies and saves changes.
