4.5.4.5.8
TCP Enhancer
When TCP Enhancer is enabled, TCP ACK packets rate on the downlink (for
uplink TCP data traffic) is moderated, thus increasing the TCP ACK rate on uplink
direction for the downlink TCP data traffic. It is mainly useful in extreme
asynchronous DL/UL ratios (e.g. DL=75/UL=25), thus maximizing capacity in
both directions.
The options are Disable and Enable. The default is Disable.
4.5.4.5.9
DFS/DCS
The DFS/DCS parameters are applicable only for 5 GHz units. The DFS (Dynamic
Frequency Selection) feature is applicable only for units using a Country Code
specifying that DFS must be used (DFS may also be enabled in units using
Universal Country Code). Note that for certain Country Codes DFS support and
Channel Availability Check Time may vary among the relevant sub-bands
supported by the Country Code.
Most parameters of the DFS and DCS features are managed at the sector level (see
"DFS/DCS (5 GHz units only)" on page
The DFS/DCS parameters at the BTS level that are common to both sectors (if
applicable) include:
Random Channel Selection
DFS Type
DFS Frequencies Management Level
4.5.4.5.9.1
Random Channel Selection
The Random Channel Selection parameter defines the method of selecting
channels for scanning by the DCS and/or the DFS mechanisms.
When the DCS mechanism is enabled and Random Channel Selection is enabled,
the list of channels to be scanned is selected randomly from the list of all available
channels in the relevant band according to the Country Code. The number of
channels in the list is defined by the Number of Channels to Scan parameter (see
"Number of Channels to Scan" on page
disabled, the list of channels will be defined by the user (see
on page
If DCS is disabled and DFS is enabled, the Random Channel Selection parameter
defines the method of selecting channels for the DFS mechanism.
