Frequency Ranges
5-GHz Frequency
Band
The FRITZ!WLAN Repeater can operate in the 5-GHz fre-
quency band as an alternative. This frequency range is
used much less frequently than the most common 2.4-
GHz frequency range.
A prerequisite for use of the 5-GHz frequency band is that
all WLAN adapters in the network support this frequency
range in accordance with the IEEE 802.11a or
IEEE 8002.11n standard.
Bandwidth
In both frequency ranges you can select between channel
bandwidths of 20 MHZ or 40 MHz (exception: channel 140
in the 5-GHz frequency band). The FRITZ!WLAN Repeater
initially attempts to select a channel with 40 MHz band-
width (throughput up to 300 Mbit/s). If this is not possible
due to interference or channels already being used by oth-
er WLANs in the vicinity, the FRITZ!WLAN Repeater auto-
matically switches over to a channel with 20 MHz band-
width. Greater bandwidth provides for higher data
throughput:
Increasing bandwidths also increases the probability of
interference by wireless networks in the vicinity. Large
bandwidths reduce the frequency range available to other
wireless networks in the vicinity.
