News Emitel to test emergency notification system in T-DAB+ Digital Broadcasting

The tests, which will be carried out by Emitel S.A. and Polskie Radio S.A, are slated to take place in December. The testing procedure will not cause any inconvenience for the audiences.

The tests are designed to check how different types of DAB+ receivers work in the case of a sudden change of signal and content of broadcasts. The test multiplex used during the procedure features eight stations named PR TEST-1 to PR TEST-8 and is broadcast in Warsaw on channel 6D (187.072 MHz) with an ERP of 0.8 kW.

The conducted tests will also encompass a solution using the EWF (Emergency Warning Functionality) concept, as well as a solution that will enable changing the content of broadcast programs to alert messages automatically.

Test results may be used in the future to inform the general public about the risks and dangers.
