2.15.2 Casio expanded features
(1) Power saving
Perform IEEE802.11-compliant power saving operation. A function to turn power saving operation off
is provided, but there is no need to turn it off if there are no particular problems.
(2) Roaming
In an environment where there are two or more access points with identical SSID codes, the roaming
function automatically switches to the access point with the better radio wave environment.
Roaming operation procedure
i The signal strength of the currently connected access point is monitored regularly, and the
following procedure is performed when that signal strength falls below a set threshold.
ii Search for access points that can communicate with the terminal, and list the signal strength of
each access point.
iii Compare signal strength of the currently connected access point with that for listed access points.
iv If the comparison proves that one of the listed access points has a better signal strength than the
one currently connected with the terminal, the terminal will make a request for roaming (to that
access point).
v If roaming permission comes from the access point to the terminal, the roaming will complete.
Factors for signal strength comparison
Comparison factors
[1] Signal strength (RSSI value) is high
[2] Signal quality is good (compared if the values for
[1] are the same)
(3) Communication standard selection
Communication can be optimized for the environment by narrowing the standards used (frequency
band, high-speed communication).
Settings to suit the usage environment.
