ROVER Header 2013
  1 LTE : What does it mean?
Long Term Evolution is the latest fronteir of UMTS telephone signals dedicated to the internet (4G). LTE signals occupy the upper part of the UHF band, for example from channels 61 to 69; channels that, until the end of 2012, were used for digital tv transmissions. LTE
  2 LTE : New UHF canalizations

This diagram shows an example of the new UHF canalization:

  • In yellow: UHF channels dedicated to Digital TV: from channel 21 to channel 60;
  • In red: new LTE channels, transmitted from repeaters:  6 channels Down;
In blue: LTE channels transmitted from mobile terminals: 6 channels Up (smartphones, tablets, etc.).

  3 LTE : Possible Interferences

This diagram shows an example of the new UHF canalization:

  • In yellow: UHF channels dedicated to Digital TV: from channel 21 to channel 60;
  • In red: new LTE channels, transmitted from repeaters:  6 channels Down;
In blue: LTE channels transmitted from mobile terminals: 6 channels Up (smartphones, tablets, etc.).
  4 LTE : ROVER's solutions - LTE Inte6rference AUTOTEST

A number of field tests showed that LTE signals may cause interference to TV systems.
The level difference between TV and LTE signals could cause intermodulation problems inside the TV band amplified by the head-end, or they could create interference in the transition zone between TV and LTE channels: for example ch 60.
These disturbances can be attenuated and/or eliminated by inserting technical corrections in the system, for example:  LTE filters.

ROVER's exclusive LTE INTERFERENCE AUTOTEST (ANALYSIS) new feature is included in all its new HD Series. This "smart function" automatically activates the Spectrum analysis and measurements, suggesting to the installer which could be the correct filter attenuation value in dB for the interfering LTE signals. Please find below three measurement examples.
