Our Services

The services provided by Kessler and Gehman Associates (KGA) since 1967 have ranged from consulting services rendered on a daily basis to studies of technical, economic feasibility and the design and construction follow-up of major telecommunications systems in widely diverse geographical areas in the United States, Hawaii, Guam, American Samoa, Puerto Rico, and the US Virgin Islands. In particular KGA has extensive experience in the design of systems in geographical areas where special attention has had to be devoted to effects of meteorological variations on system propagation reliability. Baseband information carried on communications systems designed by KGA include video, data, telemetry, supervisory, wide bandwidth audio, telephone and teletype, either in combination or individually and in analog or digital format.

The current work on the ATSC 3.0 next-generation broadcast standard is meant to address this issue, using advanced transmission and video/audio coding techniques to bring new and creative services to viewers.
