2400 MHz spectrum (WLAN)

The figure below provides a simplified overview of WLAN in the 2.4 GHz band.

In addition the the5 GHz band and the 6 GHz band are used for WLAN.

The additional bands have a shorter range due to the higher frequency, but enable significantly higher data rates due to the higher bandwidth.

Power in EIRP (Equivalent isotropically radiated power)

In the 2.4 GHz band, WLAN devices use the channels 1 (2.412 GHz) to 13 (2.472 GHz). As WLAN uses a bandwidth of approximately 20 or 40 MHz but the spacing between adjacent WLAN channels is only 5 MHz, there are overlaps between adjacent WLAN channels. Given a required bandwidth of 20 MHz, therefore, only 4 (not 13) channels can be used in practice, in this case the channels 1, 5, 9 and 13. With a required bandwidth of 40 MHz, only two channels can be used (e.g., the centre frequency of Channel 3 / Channel 11).

WLAN devices compliant with the current Commission Decision on harmonisation of the radio spectrum for use by short-range devices (SRD Decision) are harmonised Class 1 devices of Subclass 22 as defined in the RTTE Directive (Directive 1999/5/EC, implemented in the Austrian Federal Act on Radio Systems and Telecommunications Terminal Equipment [FTEG]). These devices do not require notification under Article 6.4, and their operation is not subject to any special technical or administrative requirements. Moreover, a "call sign" is not required in the CE marking for these devices.

As long as a WLAN hotspot is not offered to 3rd parties on a commercial basis, there is no obligation to notify the services to the regulatory authority (general authorization pursuant to §15 TKG 2003, AGG).
