HD RANGER 2 LTE interference

LTE interference on SMATV systems

Minimizing LTE effect on your TV system

The HD RANGER 2 has a variety of tools that allow you to compare the signal reception

quality measurements on digital TV channels with and without the LTE filter. This is very helpful to

anticipate the performance improvement you should expect on your TV distribution system well

before you physically make changes to the cabling to insert the LTE filter.

LTE interference on CATV networks

Locating interference sources to prevent service calls

Some of the bands allocated to LTE are near or inside former

television bands. For example band 5 (uplink 824-849 MHz;

downlink 869-894 MHz). The HD RANGER 2 has special

functions to help installers determine the level of activity in those

bands and therefore anticipate potential interference problems.

Downlink and Uplink interference

Visualizing the two different scenarios

Downlink interference comes from the mobile phone base stations

which are placed at fixed locations and are always on. This is not the

case of Uplink interference which comes from the handheld devices

and therefore it can be a lot more difficult to locate and mitigate.
