I-19, the Canamex Interstate Highway, is the home of the "worlds first highway Wi-Fi mobile voice and high speed data network," from Rio Rico to South of Green Valley, Arizona according to New Zealand based RoamAD, which supplied the Wi-Fi mesh software used in the networks infrastructure.
In a live demo users were able to make multi-party VOIP conference calls at over 80 miles per hour across the network.
The network is being built by the Wi-VOD Corporation under a grant from the US Department of Homeland Security, and uses RoamADs mesh technology for scalable metro Wi-Fi networks.
Initially the network will serve police, fire, ambulance and US Border Patrol operations. Later, according to RoamAD, other "community agencies, schools, business and local residents" will be added as the network expands.
