DTG Testing awarded at800 4G filter testing contract

DTG Testing has been awarded the contract to test filters that will be used to protect digital terrestrial television from interference by 4G mobile broadband signals at 800 MHz.

at800 is the brand name of Digital Mobile Spectrum Limited (DMSL), the not-for-profit organization that has been formed by, and represents, mobile network operators with spectrum at 800 MHz. Its role is to mitigate the interference caused by the roll-out of 4G to digital terrestrial television (Freeview). at800 has commissioned DTG Testing to verify that the filters it supplies meet its specifications.

DTG Testing will also provide a conformance testing service for manufacturers wishing to supply filters to the retail market. Filters that pass DTG Testing’s rigorous testing will be given the rights to use the at800 logo.

Richard Carlton, Associate Director at DTG Testing said: “The introduction of 4G later this year will mean faster, more reliable mobile internet services for consumers but could also disrupt a minority of viewers’ Freeview services. As the digital TV industry’s test centre we are committed to ensuring that new technologies work alongside existing digital TV services in the UK.

Simon Beresford-Wylie, CEO, at800 added: “Using a trusted body such as DTG Testing to ensure conformance of the filters we supply is an important step. It allows householders, professional installers and the retail industry to be confident that filters with the at800 logo meet the parameters required to mitigate interference of 4G services at 800 MHz.”

DTG Testing conformance testing services for manufacturers wishing to supply filters using the at800 logo to the retail market will be available from 18 March 2013.
