 5 5 - MATERIAL SENSING DEVICES USING UWB TECHNOLOGY  
5.1- Material sensing devices 
Material sensing devices permitted under this De cision shall fulfil the following requirements: 
• Fixed installation (application A)  
- The transmitter has to switch off if the machine is not running, “running sensor”; 
- The transmitter shall implement a TPC with a dynamic range of 10 dB, as described in 
the harmonised standard EN 302 498-2 for ODC ( Object Discrimination and 
Characterisation ) applications; 
- The transmitter shall be attached to a fixed installation. 
• Non-fixed installation (application B) 
- Transmitter-on only if manually operated wi th a non-locking switch  (e.g. it may be a 
sensor for the presence of the operators hand) plus being in contact or close proximity 
to the investigated material and the emissions being directed into the direction of the 
object (e.g. measured by a proximity sensor or imposed by the mechanical design); 
- The transmitter has to switch off if the machine is not running, “running sensor” 
Emissions radiating from material sensing devices permitted under this decision shall be kept to a 
minimum and in any case not exceed the e.i.r.p. density limits within the following Table. The 
compliance with the limits of the following Table for non-fixed installations (application B) has to be 
ensured with the device on a representative structure of the investigated material (e.g. 
representative wall as defined in ET SI EN 302 435-1 or ETSI EN 302 498-1). 6

The peak e.i.r.p. (in dBm) measured in a bandwidth of 50 MHz shall be less than a limit that is obtained by 
adding a conversion factor (25 dB) to the ‘maxim um mean e.i.r.p. density’ (in dBm/MHz) limit. 
1 devices using a Listen Before Talk (LBT) mechan ism, as described in the harmonised standard EN 
302 498-2, which meet the technical requirements de fined within the Table below, are permitted to 
operate in frequency ranges 2.5 to 2.69 and 2.9 to 3.4 GHz with a maximum mean e.i.r.p. density of    
–50 dBm/MHz. 
a) Technical requirements of the Peak power th reshold value for the “Listen Before Talk” (LBT) 
mechanism to ensure the protection of the list ed services are defined in the table below: 
Frequency range Radio service to be detected Peak power threshold value 
2.5 - 2.69 GHz Land Mobile service -50 dBm/MHz 
2.9 - 3.4 GHz Radiodetermination Service -7 dBm/MHz 
b) Additional requirements for Radar detection: Cont inuously listening and auto matic switch-off within 
10ms for the related frequency range if the threshol d value in Table above is exceeded. A silent time 
of at least 12s while listening continuously is nece ssary before the transmitter can be switched on 
again. This silent time during whic h only the LBT receiver is active has to be ensured even after the 
device is switched off by the functions described in  5.1, the proximity sensor and manual operation. 
2 to protect the radio services, non-fixed installa tions (application B) must  fulfil the following 
requirement for total radiated power spectral density: 
a) In the frequency ranges 2.5 to 2.69 GHz and 4.8 to 5 GHz, the total radiated power spectral density has 
to be 10 dB below the maximum e.i.r.p. density; 
b) In the frequency ranges 3.4 to 3.8 GHz, the total radiated power spectral density has to be 5dB below 
the maximum e.i.r.p. density. 7 3 Limitation of the Duty Cycle to 10% per second. 8 5.2- Building material analysis devices (BMA) 
1) BMA Devices permitted under this Decisi on shall fulfil the following requirements: 
a) Transmitter-On only if manually operated with a non-locking switch plus being in 
contact or close proximity to the inves tigated material and the emissions being 
directed into the dir ection of the object;  
b) The BMA transmitter has to switch-off after max 10s without movement; 
c) The Total Radiated Power spectral density has to be 5 dB below the maximum mean 
e.i.r.p. density limits in the table below; 
2) Emissions radiating from BMA devices shall be kept to a minimum and in any case not  
exceed the e.i.r.p. density limits within the table below with the BMA device on a 
representative wall as defined within ETSI Standards EN 302 435-1 and EN 302 498-2.

¹ Devices using a Listen Before Talk (LBT) mechanism  described in the harmonised standard EN 302 435-
1 are permitted to operate in frequency range 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 and 2.7 to 3.4 GHz with a maximum 
mean e.i.r.p. density of –50 dBm/MHz. Technical requirements of the peak power threshold value for 
the LBT mechanism to ensure the pr otection of the listed services are defined in the table below: 
Frequency range Radio service to be detected Peak power threshold value 
1.215 - 1.4 GHz Radiodetermination service +8 dBm/MHz 
1.61 – 1.66 GHz Mobile satellite service -43 dBm/MHz 
2.5 - 2.69 GHz Land mobile service -50 dBm/MHz 
2.7 - 3.4 GHz Radiodetermination service -7 dBm/MHz 
 Additional requirements for Radar detection: Cont inuously listening and auto matic switch-off within 
10ms for the related frequency range if the threshold va lue in table above is exceeded. A silent time of 
at least 12s while listening continuously is necessary before the transmitter can be switched on again. 
This silent time during which only the LBT receiver is ac tive has to be ensured even after the device is 
switched off by the functions described above, the proximity sensor and manual operation. 
2 To protect the Radio Astronomy Service (RAS) bands 2.69 to 2.7 GHz and 4.8 to 5 GHz, the Total 
Radiated Power spectral density has to be below -65 dBm/MHz.
