This subsection provides details on wireless network parameters for performance tuning . Changing options in this
section may affect overall performance of your SW550X; therefore, please be cautious . If you are still unclear on
the effect of each option, please refrain from altering it . Figure below depicts the Wireless Advanced Settings page .

infrastucture

Radio Off – When this option is enabled, this allows the user to turn off the wireless interface completely .
 P2P Button – SW550XC has an external physical WPS button called P2P Button, which can create “WI-FI
direct” and “serial auto link” communication. The setting is enabled by default. Please refer to Section 5.3.5
for the operation steps.

Fast Handoff – This option enables Atop ’ s proprietary protocol to speed up roaming between AW5500Cs
( Atop ’ s Industrial Wireless Serial Device Servers ) in addition to Fast Roaming ( next option ). Enable this option
to allow AW5500C to share its neighboring AW5500C information to SW550XC to further reduce its roaming
time .
 Fast Roaming
–
Enable this option to allow SW550XC to scan for available access points in the background
to speed up roaming when necessary.

Roaming Threshold – This option set the threshold level used to determine when SW550XC should try to
connect to another access point when the wireless signal drops below the selected range . The available
thresholds are Low ( 25 %) , Normal ( 50 %) , and High ( 75 %).
 Tx Power – This option allows user to set the SW550XC’s Transmission Power . The transmission power can
be reduced to prevent wireless interference to other wireless networks .

Regulatory Domain – This can be selected from 4 options in the drop - down list box : CN ( APL1_WORLD ) ,
EU ( ETSI2_WORLD ) , TW ( APL3_FCCA ) , US ( FCC5_FCCA ) , and VN ( ETSI3_WORLD ). Note that different
Regulatory Domains will result in different radio channels / frequencies being allowed SW550XC to operate
( see Channel setting in previous subsection ).

STP – The Spanning Tree Protocol is only available in the AP Client mode . Enable this option if STP is enabled
