Evolving Challenges in LTE/Cable Interference Issues

Source: Rohde & Schwarz GmbH & Co. KG

The deployment of LTE at 700 MHz has important implications for the cable industry with regards to signal ingress and egress. Awareness of this issue has resulted in the availability of tools for detecting, locating, and resolving cable egress. However, field investigations have shown that signal egress at lower (VHF airband) frequencies is not a reliable predictor of leakage at the higher frequencies used for LTE. This paper will discuss the results of continued field trials and studies in the area of LTE/cable interference, and will present information regarding ongoing LTE developments that may have an impact on cable systems.
