Wireless LAN
■ The range of your wireless devices can be affected when the antennas
are placed near metal surfaces and solid high-density materials.
■ Range is also impacted due to "obstacles" in the signal path of the radio
that may either absorb or reflect the radio signal.
Supported Frequency Sub-bands
Subject to the radio regulations that apply in the countries/regions, your
Wireless LAN module may support a different set of 5 GHz/2.4 GHz
channels. Consult your Authorized Wireless LAN or TOSHIBA Sales office
for information about the radio regulations that apply in the
countries/regions.
2.4 GHz Band Channels Sets (Wireless IEEE 802.11 Revision B, G and N)
*1 Factory-set default channels
*2 The band width and the channel which can be used depends on the
installed wireless LAN module. And the approved channels on using are
different at each country or region. The channel configuration is managed
as follows:
■ For wireless clients that operate in a Wireless LAN Infrastructure, the
Wireless LAN module will automatically start operation at the channel
identified by the Wireless LAN Access Point. When roaming between
different access points the station can dynamically switch to another
channel if required.
■ For Wireless LAN modules installed in wireless clients that operating in
a peer-to-peer mode, the module will use the default channel 10.
