Digital TV Labs launches 4G interference testing service

Digital media testing company Digital TV Labs has launched a service to test UK Freeview receivers for susceptibility to interference from 4G LTE mobile services. 

New 4G services broadcasting in the 800 MHz band can interfere with both Freeview DVB-T and Freeview DVB-T2 terrestrial reception in some areas, though a special filter between the antennae and receiver of the affected households can prevent this, said Digital TV Labs.

The firm said it is now able to provide manufacturers with a comprehensive 4G LTE test service to ensure a basic level of immunity on DVB terrestrial receivers.

“The introduction of 4G means faster, more reliable mobile internet services for consumers but it can also disrupt some Freeview services. By validating Freeview receivers’ immunity, manufacturers can avoid potential disruption to end user TV experience,” said Keith Potter, CEO of Digital TV Labs.

Digital TV Labs claims to be the world’s largest independent and specialist digital TV testing company, with lab facilities in the UK and Hong Kong.
