Before Operating Your Notebook
Data Communication by Radio Wave
Wireless means using radio frequency signal to do
data exchange without LAN cable.
Internet Connection Capability
Combined with router and access point, the notebook
can access internet without any LAN cable.
If the security setting is not done, it is posible to occur problem
when you exchange information with wireless LAN.
ϥ
Communication contents can be peeped
It is possible for the third party with malice to intercept radio
wave intentionally.The following kind of communication contents
can be peeped.
垸
Private information such as ID, password or credit card
number etc.
垸
Mail contents
ϥ
Wireless LAN Invasion
It is possible for the third party with malice accessing the
private/company network without permission and doing
the following kind of behaviors:
垸
Retrieve private and confidential information (secret disclosure)
垸
Send a program that appears legitimate to the notebook, but
performs some illicit activity when it is run.(Trojan)
垸
Rewrite the communication contents (alteration)
垸
Infect computer virus and destroy the system (destruction)
It is customer's responsibility to do the setting of network security.
The customer has to sufficiently understand the result occured
without setting network security.
The specification of Wireless LAN module.
ϡ
Transmission speed and communication range is changable.
They depend upon radio wave environment, the connected
equipment and the application applied.
ϡ
Transmission speed is the speed definied by standard
(theoretical value), it differs from actual data rate.
ϡ
When the radar wave (weather radar and the like) is
detected wihile doing the communication, for modifying
the automatic channel operation, sometimes the
communication is discontinued.
