Ringtail Technologies CEO Ryan Younger demonstrated his company’s wireless communications system Tuesday at The Library Downtown. He said it can make “affordable Internet, television and telephone service available to underserved markets.” Younger said the technology can be provided to any television set via a “rabbit ear” antenna and set-top receiver and estimated the cost at $50 per month for all three products. The company is seeking more than $3 million in funding for the project and if successful could set up a headquarters and fabrication center at The Library.
