Phoenix Model Market Adds SFN to Improve NextGen TV Reception
Single frequency network was installed by KASW
PHOENIX—NextGen TV service is getting a boost in Phoenix, as the Phoenix Model Market has announced the installation of a Single Frequency Network with the goal of improving reception for viewers and broaden the reach of broadcasters transmitting to NextGen TV sets.
An SFN uses multiple transmitters placed on the air within the coverage area on the same channel and carrying the same services. This increases the signal level available for over-the-air viewing and decreases the viewer’s need for a complex receiver antenna, while also enabling future use of mobility services to NextGen TV-equipped devices, says Pearl TV engineer David Folsom, who worked on the Phoenix SFN.
E.W. Scripps-owned KASW, a CW affiliate, installed the SFN and is acting as the host station. Hitachi-Comark provided the transmission equipment required at both its South Mountain and Shawn Butte SFN node locations. The tower and transmission facilities were provided by American Tower Corporation. In addition, Electronics and Telecommunications Research Institute and manufacturers Cleverlogic, Agos and KaiMedia have provided test equipment and technical support to calibrate the SFN.
