Access points often have built-in DSL modems. These so called routers establish the
connection to the existing DSL Internet connection and the Wi-Fi.
A connection can also be established to another end device with Wi-Fi functionality
without an access point. Without a router, however, the network is restricted to those
devices directly connected to it.
If encryption is used for the transfer, the same procedure must be used for all devices.
Encryption is a procedure to protect the network from unauthorised access.
The transfer speed can vary depending on the distance and the number of users
accessing the remote station.
16.3. Bluetooth®
Bluetooth technology is used to wirelessly bridge short distances. Bluetooth devices
transfer data via radio so that computers, mobile phones, printers, keyboards, mice
and other devices can communicate with one another wirelessly. Bluetooth wireless
technology has numerous possible applications. A few of them are listed below:
• Creating a wireless Internet connection using a mobile phone.
• Transferring files between computers or between a computer and another device.
• Printing using a Bluetooth printer.
• Using a Bluetooth keyboard and mouse.
• Connecting to a PAN (Personal Area Network).
The Bluetooth wireless technology data transfer speed can vary depending on the
device or environmental factors. Data can be transferred through walls, jacket pockets
and briefcases using a Bluetooth device. The transfer between Bluetooth devices occurs
at the high frequency of 2.4 Gigahertz (GHz).
Do not operate the Bluetooth function in locations (e.g.: hospitals,
aeroplanes, etc.) where there is sensitive equipment. Do not switch the
device unless you are sure it will cause no interference.
16.4. Airplane Mode
In flight mode, all wireless connections (e.g. Wi-Fi, Bluetooth®) are disabled. The airplane
mode is disabled by default to ensure that all wireless connections are available.
