LTE Ingress test

Description

Long Term Evolution is a new standard for mobile networks. This mobile
communication standard uses a frequency band close to the bands used by
television. For this reason it can cause interferences.
The LTE Ingress Test identifies this type of interferences in a television
distribution system, so that they can be compared on the same screen
measurements with LTE filter and without LTE filter and thus if there is any
interference it can be detected and take appropriate action to fix it.
