quired, before occupying a free channel. During this period
you cannot register any wireless devices. The wireless LAN
connection is then established automatically.
A prerequisite for use of the 5-GHz frequency band is that
wireless devices used in the network support this frequency
range in accordance with the IEEE 802.11a, IEEE 8002.11n or
IEEE 802.11ac standard.
In the 5-GHz frequency band, two large ranges of frequencies
can be used: 5.15 GHz to 5.35 GHz, and 5.47 GHz to 5.805
GHz. In the EU, up to 19 channels are available in these rang-
es:
5150 - 5350 MHz (channels 36, 40, 44 , 48, 52, 56, 60 and
64)
5470 - 5725 MHz (channels 100, 104, 108, 112, 116, 120,
124, 128, 132, 136 and 140)
Different conditions may apply for the individual ranges.
2.4 GHz and 5 GHz
The FRITZ!Box works in the wireless network in the 2.4-GHz
range and parallel in the 5-GHz range. Both frequency ranges
can be used simultaneously for wireless connections. This
means you always have the optimum data connection at your
disposal:
•
For applications that rely on a steady, high throughput
rate (“streaming”), use the 5-GHz frequency band. This
radio band provides more channels, and these channels
do not overlap, as well as experiencing significantly less
external interference.
•
For applications that require a low to normal throughput
rate (for instance, reading and writing e-mail), use the
2.4-GHz frequency band.
