  • FFT Tap WiFi Extension Device
    Publication number: 20150067755
    Abstract: Techniques for adding WiFi capabilities to a region may include installing WiFi access points in a cable television (CATV) system. For easier installation of the WiFi access points, a WiFi access point extension devices may be integrated into existing taps in the CATV system. The WiFi extended taps are able to provide radio frequency (RF)/CATV signals to subscribers, provide power to the respectively integrated WiFi access point, and maintain power to the coaxial transmission line during installation. During installation, the WiFi access point extension devices can be integrated into the CATV outdoor distribution plant without having to splice into an existing coaxial transmission line. The multiplicity of existing tap locations in CATV distribution plants makes the positioning of new wireless access points extremely versatile for the cable provider.
