LTE Long Term Evolution

June 1, 2012.

When a TV distribution system is interfered by a mobile phone cell the use of an LTE filter is recommended. The field strength meter model RANGERNeo + 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.

There are a large number of frequency bands allocated to LTE some of which are near or inside television bands. For instance band 5 (uplink 824-849 MHz; downlink 869-894 MHz) or band 3 (uplink 1710-1785 MHz; downlink 1805-1880 MHz). The field strength meter model RANGERNeo + has special functions to help installers determine the level of activity in those frequency bands and therefore be able to anticipate potential interference problems.
