Selecting Public consultation No 40/2021  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  The internal signal enhancer is an equipment used to expand the coverage 
area of telecommunications signals in shadow areas or  areas with low signal intensity, 
being of great relevance to expand the coverage of mobile networks in indoor 
environments where the signal strength of the network is insufficient to establish voice 
calls or data connections with a minimum of quality. Whe n improperly installed and 
operated or when the equipment does not have characteristics aimed at preventing the 
occurrence of harmful interference, the signal enhancer has great interfering potential in 
the frequency ranges granted to personal mobile servi ce providers (SMP and other 
services). It is then understood that the certification of equipment with self -monitoring 
characteristics is essential to reduce the number of complaints about interfering G/TBT/N/BRA/1232

the use of these kind of equipment.; Quality requirements
