FRITZ!WLAN USB Stick 34
Range The range within a WLAN is highly dependent on the fol-
lowing three factors:
• the WLAN adapter used,
• the structural conditions, and
• the amount of radio traffic on the same frequency
band. Other wireless networks may be active, but al-
so what are known as analog interferers (for instance
baby m
onitors, video bridges, DECT telephones,
Bluetooth transmitters for mobile telephones, and
microwave ovens).
IEEE 802.11b With a maximum throughput rate of 11 Mbit/s, this is the
oldest standard for radio networks in the 2.4-GHz frequen-
cy range (ISM). First-generation WLAN access points, for
exam
ple, can use this standard to communicate with the
FRITZ!WLAN USB Stick.
IEEE 802.11g This is currently the most common WLAN standard. It
communicates with a maximum of 54 Mbit/s gross in the
2.4-G
Hz frequency range (ISM) and guarantees broad
compatibility with many WLAN devices.
However, due to heavy use of the 2.4-GHz range, interfer-
ence is quite common.
IEEE 802.11n This standard provides for high throughput speeds and
ranges. The FRITZ!WLAN USB Stick supports 802.11n in
the 2
.4-GHz frequency band.
The use of the 802.11n standard—and thus the availabili-
ty of higher throughput rates—is possible only if the WLAN
co
nnection is secured using the WPA2 security mecha-
nism (AES-CCMP).
