◆ Wireless LAN (WLAN)
・
Wireless LAN (WLAN) exchanges information using radio
waves, and allows you to freely establish LAN connection if
you are within an area where radio wave reaches. On the
other side, if you communicate without appropriate
security settings, communications may be intercepted or
hacked by malicious parties. It is recommended to make
necessary security settings on your judgement and
responsibility.
・
Wireless LAN
Do not use wireless LAN in a place where magnetized by
electric products, AV, OA equipment, etc. or where
electromagnetic wave is generated.
- If magnetism or electrostatic noise affects the terminal,
noise may be increased or communication may not be
available (especially when using microwave oven, it may
affect the terminal).
- Using near TV or radio may cause poor reception or TV
screen may be blurred.
- When multiple wireless LAN access points exist near the
terminal and they use the same channel, search may not
be performed correctly.
・
Frequency bands
Frequency bands used by the terminal wireless LAN
function are as below.
a
2.4 : Radio equipment that uses the 2400 MHz band.
b
DS : The modulation is the DS-SS method.
c
OF : The modulation is the OFDM method.
d
4 : The expected interference distance is 40 m or shorter.
e
: All bandwidths between 2400 MHz and
2483.5 MHz are used, and the bandwidth used by mobile
object identification devices can be avoided.
Using wireless LAN built-into the terminal in 5.2/5.3 GHz
outside is prohibited by the Radio Law.
Available channels vary by countries. To use WLAN
overseas, check the conditions such as available frequency,
regulation, etc. for the country.
To use in airplane, confirm with airline company in advance.
When docomo mini UIM card is not inserted or when you
are out of service area, channels 12, 13 of 2.4 GHz band and
5 GHz band are not available regardless of whether you are
in Japan or abroad.
Cautions on using 2.4 GHz devices
In the frequency band used by WLAN devices, in addition
to home electric appliances such as a microwave oven
and industrial/scientific/medical devices, in-plant radio
stations for identification of mobile objects used in
production lines of a factory (a license is required),
specified low power radio stations (a license is not
required), or amateur radio stations (a license is required)
can be in operation.
1. Before using this device, confirm that in-plant radio
stations for identification of mobile objects, specified
low power radio stations or amateur radio stations are
not in operation in your neighborhood.
