  3. What is LTE ? • LTE (Long Term Evolution) is a 4th generation (4G) standard for mobile communication. • Currently 17 communication companies worldwide have adopted LTE, more than 100 more are about to follow. • LTE uses - FDD (Frequency Division Duplexing) and - TDD (Time Division Duplexing) protocols • FDD : LTEbase stations and handheld devices use different bands • TDD : LTE base stations and handheld devices use the same bands

  8. LTE Interference to DTT • When LTE uses the 800 MHz “digital dividend” (Europe 790-864MHz) or the 700 MHz “white space” band (USA 698-806MHz) there will be interference with digital video broadcast signals (DVB-T/ATSC). DTV picture noise: How to solve this problem?

  10. Soontai LTE Filter LTE is the 4th generation mobile communication standard. This standard uses the frequency band next to the DVB-T band (790 - 862MHz in Europe, 698 - 806MHz in the Americas), which will lead to interferences with DVB TV or set-top-boxes. According to tests from Ofcom this interference can be eliminated with the help of a high rejection low pass filter. Our LTE Filters pass all requirements to eliminate interferences by LTE signals on digital broadcast reception. As a professional filter designer, Soontai can offer the LTE filter in a variety of packages and frequencies for various markets. Your inquiries are welcome.
