QuoteNethercomm, a San Diego-area start-up, says it has developed technology to send lightning-fast broadband and TV services via wireless signals through the pipes that deliver the fuel used to heat homes and fire up stoves. Gas pipes serve 62% of U.S. households, says the American Gas Association. Broadband in Gas, or BIG, could give consumers a third high-speed option at low costs and speeds that far surpass today's phone and cable offerings. It also could bring fast Internet to unserved rural areas. But, so far, the idea has been met with both excitement and skepticism.
