1.2. Appropriate mitigation techniques

Equipment using ultra-wideband technology shall also be allowed to use the radio spectrum with higher e.i.r.p. limits than mentioned in the table in section 1.1 when applying additional mitigation techniques as described in the relevant harmonised standards adopted under Directive 1999/5/EC or other mitigation techniques on condition that it achieves at least an equivalent level of protection as provided by the limits in the table in section 1.1. The following mitigation techniques are presumed to provide such protection:

1.2.1. “Low duty cycle” (LDC) mitigation

A maximum mean e.i.r.p. density of – 41,3 dBm/MHz and a maximum peak e.i.r.p. of 0 dBm measured in 50 MHz shall be allowed in the 3,1-4,8 GHz bands provided that a low duty cycle restriction is applied in which the sum of all transmitted signals is less than 5 % of the time each second and less than 0,5 % of the time each hour, and provided that each transmitted signal does not exceed 5 ms.

1.2.2. “Detect and avoid” (DAA) mitigation

A maximum mean e.i.r.p. density of – 41,3 dBm/MHz and a maximum peak e.i.r.p. of 0 dBm measured in 50 MHz shall be allowed in the 3,1-4,8 GHz and 8,5-9,0 GHz bands provided that a detect and avoid (DAA) mitigation technique as described in the relevant harmonised standards adopted under Directive 1999/5/EC is used.

1.3. Operation of equipment using ultra-wideband technology in automotive and railway vehicles

In derogation to Article 3 of this Decision, use of ultra-wideband equipment shall also be allowed in automotive and railway vehicles when in accordance with the following parameters.

1.3.1. Maximum e.i.r.p. densities for operation of ultra-wideband technology in automotive and railway vehicles

Equipment using ultra-wideband technology in automotive and railway vehicles shall be allowed to use the radio spectrum with the e.i.r.p. limits given in section 1.1 provided that for the bands 4,2–4,8 GHz and 6,0–8,5 GHz the following parameters are applied:

Frequency range (GHz) Maximum mean e.i.r.p. density (dBm/MHz) 4,2 to 4,8 until 31 December 2010 –41,3 provided that techniques to mitigate aggregate interference are applied that provide at least equivalent performance to the techniques described in harmonised standards adopted under Directive 1999/5/EC must be used. These require a transmitter power control (TPC) range of at least 12 dB. – 53,3 (otherwise) beyond 31 December 2010 –70,0 6,0 to 8,5 –41,3 provided that techniques to mitigate aggregate interference are applied that provide at least equivalent performance to the techniques described in harmonised standards adopted under Directive 1999/5/EC must be used. These require a transmitter power control (TPC) range of at least 12 dB. – 53,3 (otherwise)

1.3.2. Appropriate mitigation techniques in automotive and railway vehicles

Operation of equipment using ultra-wideband technology in automotive and railway vehicles shall also be allowed with other e.i.r.p. limits than mentioned in section 1.3.1 when applying additional mitigation techniques as described in the relevant harmonised standards adopted under Directive 1999/5/EC or other mitigation techniques on condition that it achieves at least an equivalent level of protection as provided by the limits in the previous tables. The following mitigation techniques are presumed to provide such protection:

1.3.2.1. “Low duty cycle” (LDC) mitigation

The operation of equipment using ultra-wideband technology in automotive and railway vehicles which applies the LDC mitigation technique in the 3,1-4,8 GHz band as described in section 1.2.1, shall be allowed with the same e.i.r.p. limits as described in that section 1.2.1. The e.i.r.p. limits mentioned in section 1.1 shall apply for the other frequency ranges.

1.3.2.2. “Detect and avoid” (DAA) mitigation

The operation of equipment using ultra-wideband technology in automotive and railway vehicles which applies the DAA mitigation technique in the 3,1-4,8 GHz and 8,5-9,0 GHz bands shall be allowed with an e.i.r.p. limit of – 41,3 dBm/MHz provided that techniques to mitigate interference are applied that provide at least equivalent performance to the techniques described in harmonised standards adopted under Directive 1999/5/EC. These require a transmitter power control (TPC) range of at least 12 dB. In other cases an e.i.r.p. limit of – 53,3 dBm/MHz applies.

2. SPECIFIC UWB USAGE

Signals that are radiated into the air that do not exceed the limits in the table below shall be allowed.

2.1. Building material analysis (BMA)

Frequency range (MHz) Maximum mean e.i.r.p. density (dBm/MHz) Maximum peak e.i.r.p. density (dBm/50 MHz) Below 1 730 –85 –45 1 730 to 2 200 –65 –25 2 200 to 2 500 –50 –10 2 500 to 2 690 –65 –25 2 690 to 2 700 –55 –15 2 700 to 3 400 –82 –42 3 400 to 4 800 –50 –10 4 800 to 5 000 –55 –15 5 000 to 8 000 –50 –10 8 000 to 8 500 –70 –30 Above 8 500 –85 –45

BMA equipment using mitigation techniques that provide at least equivalent performance to the techniques described in the relevant harmonised standards adopted under Directive 1999/5/EC, is permitted to operate in frequency ranges 1,215 to 1,73 GHz, with a maximum mean e.i.r.p. density of – 70 dBm/MHz, and in the frequency ranges 2,5 to 2,69 GHz and 2,7 to 3,4 GHz, with a maximum mean e.i.r.p. density of – 50 dBm/MHz on condition that at least an equivalent level of protection as provided by the limits in the above table is achieved.

In order to protect Radio Astronomy Services; in the frequency range 2,69 GHz to 2,70 GHz and in the frequency range 4,8 to 5 GHz; the total radiated power density has to be below – 65 dBm/MHz as described in the relevant harmonised standards adopted under Directive 1999/5/EC.’
