Metricom Inc. Ricochet wireless modem

Starting in the mid-1990s, Metricom Inc. provided wireless Internet service for customers in select cities with a wireless mesh network of radios mounted on street lamps. Originally intended to serve utility companies, these radios served as repeaters for packets of data at rates up to 128 kilobits per second, which was a more satisfying speed than most dial-up connections at the time. The service predated most WiFi and digital cellular networks and was surprisingly affordable. Due to the bankruptcy of the company, most of the service was shut down in 2001.
