Information about regulation and annex for wideband communication systems are only available in Estonian: Raadiosageduste kasutamise tingimused ja tehnilised nõuded sagedusloast vabastatud raadioseadmetele Lisa 6 table see table 6.1 for 2.4 GHz and table 6.2 for 5 GHz systems. 2.4 GHz Frequencies 2400-2483,5 MHz e.i.r.p. 100 mW and power spectral density 100 mW/100 kHz e.i.r.p. if frequency hopping is used and 10 mW/MHz e.i.r.p. otherwise can be used. Equipment should avoid harmful interference using measures described in 2014/53/EU or at least as effective.

At frequencies 5470 MHz – 5725 MHz e.i.r.p 1 W and power spectral density 50 mW/MHz e.i.r.p can be used. When using frequencies 5250 MHz – 5350 MHz and 5470 MHz –5725 MHz equipment: 1. Must use automatic power control (reducing power at least 3 dB) 2. Reduce max average e.i.r.p. and power spectral density 3 dB or 3. Use radio interference reduction methods described in ITU-R recommendation M.1652 annex 1 It is not allowed to cause interference to meteorological radars operating between 5600 MHz and 5650 MHz.

We are working on a big regulatory project and we must be aware of some details regarding WiFi. We will highly appreciate your assistance in helping us to get the following information: 2.4 GHz: - What are the IEEE 802.11 standards for 2.4 GHz band in your country? - Channels Allowed for 2.4 GHz band - Maximum Transmit Power (Radio Tx + Antenna Gain = EIRP) for 2.4 GHz band - Is 2.4 GHz band allowed for both Indoor and outdoor? 5 GHz - What are the IEEE 802.11 standards for 5 GHz band? - Channels Allowed for 5 GHz band - Maximum Transmit Power (Radio Tx + Antenna Gain = EIRP) for 5 GHz band - Is 5 GHz band allowed for both Indoor and outdoor? - Channel bandwidth for 5 GHz band - What are the requirements for DFS and TPC for 5 GHz band? Thank you very much for your great assistance. Have a very nice day. Best regards, 2 3
