Effects of LTE signals on cable TV devices

Summary form only given. Personal phones and computing tablets are being widely deployed with 4G/LTE wireless communication capability. Some of the frequencies allocated for these devices are also used by cable TV multiple-system operators (MSOs) to deliver video and data services to homes. This raises the question of how susceptible the cable TV system is to interference from LTE signals. Set top boxes and cable modems are used as end point devices in an MSO cable plant. These devices are fed the RF signals over coaxial cable. To investigate the possible interactions between radiated LTE signals and cable systems, a number of tests were developed and conducted at NIST (National Institute of Standards and Technology).
