decree of the federal office for communications on telecommunications installations ooit partial revision of the decree of the federal office for communications on telecommunications installations ooit . some radio interface regulations have also been updated to take into account changes occurred in the spectrum management. sharing conditions in the 10.6-10.68 ghz band between the fixed service and the earth exploration satellite service have been reviewed according to ecc dec 10 01. in the frequency band 433.050 - 434.790 mhz with 1 mw transmit power and with 100 duty cycle voice applications are allowed with advanced mitigation techniques and in the same frequency band with 10 mw transmit power and 10 duty cycle analogue audio applications other than voice are excluded. in the frequency band 434.040 - 434.790 mhz with 10 mw transmit power and with 100 duty cycle voice applications are allowed with advanced mitigation techniques. in the frequency bands 863.000 865.000 mhz and 869.400 869.650 mhz a duty cycle of maximum 0.1 or mitigations techniques as lbt afa will be required. in the frequency bands 865.000 868.000 mhz and 869.700 870.000 mhz a duty cycle of maximum 1 or mitigations techniques as lbt afa will be required. according to annex 10 of erc rec 70-03 the frequency band 786 - 789 mhz can be used with a license for wireless microphones with an effective radiated power of maximum 12 mw and without a license for wireless microphones with an effective radiated power of maximum 1 mw. the frequency band 823 - 826 mhz can be used with a license for wireless microphones with a radiated power of maximum 20 mw eirp or maximum 100 mw eirp for body worn wireless microphones and without a license for wireless microphones with an effective radiated power of maximum 1 mw. the frequency band 826 - 832 mhz can be used with a license for wireless microphones with a radiated power of maximum 100 mw eirp and without a license for wireless microphones with an effective radiated power of maximum 1 mw. in the frequency band 26.960 27.410 mhz the maximum transmitter power will be increased to 4 watts rms for dsb modulated am and 12 watts pep for ssb modulated citizen band equipment according to the new ecc decision ecc dec 11 cc
