12.2.1. Requirements
A so-called WLAN access point may be used as a remote station. A WLAN access
point is a radio transmitting device that communicates with your Notebook and
controls access to the connected network.
WLAN access points are frequently found in large offices, airports, train stations, uni-
versities or Internet cafés. They provide access to particular services and networks
or to the Internet. Access permissions are generally necessary and often result in us-
age charges. Access points often have built-in DSL modems. These so-called routers
establish the connection to the existing DSL Internet connection and the wireless
LAN. A connection can also be established to another end device with wireless LAN
functionality without an access point. Without a router, however, the network is re-
stricted to those devices directly connected to it. The wireless network connection
works in accordance with the IEEE 802.11n standard and is compatible with the IEEE
802.11ac standard. 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 un-
authorised access. The transfer speed can vary depending on the distance and the
number of users accessing the remote station.
12.3. 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 de-
vice.
•
Printing using a Bluetooth printer.
•
Using a Bluetooth keyboard and mouse.
•
Connecting to a PAN (Personal Area Network).
•
Synchronising a personal digital assistant (PDA) with a computer or other device
that uses Bluetooth.
The Bluetooth wireless technology data transfer speed can vary depending on the
device or environmental factors. Data can be transferred through walls, jacket pock-
ets and briefcases using a Bluetooth device. The transfer between Bluetooth devices
occurs at the high frequency of 2.4 Gigahertz (GHz). For Bluetooth high speed data
transfer, WLAN must be enabled and the partner station must also support the high
speed mode.
CAUTION!
Do not operate the Bluetooth function in locations (e.g.: hos-
pitals, aeroplanes, etc.) where there is sensitive equipment. Do
not switch the device unless you are sure it will cause no inter-
ference.
