This works just like the personal Wi-Fi hotspots that have a cell modem on one end bringing a signal in, and a Wi-Fi connection on the other to link to local devices. Technically, such connectivity is achieved via a cellular connection to a mobile router. Chief among them is the real problem of trying to provide solid Internet connectivity to vehicles moving at high speeds, sometimes 60 mph or faster. Roadblocks in the Wayīut as it turns out, putting Internet access into moving vehicles has presented more than its share of speed bumps. Like putting Wi-Fi into libraries and schools, adding Internet access to transportation seemed like the next step in civic services, with many cities and municipalities announcing project plans during the past decade. The idea of making wireless Internet access available on commuter systems is obviously appealing to many, bringing better communication and the possibility of work productivity to what was historically regarded as time when you couldn’t do much more than read the paper. In Silicon Valley, the light rail service that runs from Mountain View to San Jose uses 4G cellular to provide Wi-Fi service to all its trains-perhaps an appropriate feature for a train line that runs right through the heart of America’s biggest concentration of technology companies. That advancement means a lot more mobile bandwidth that transit operators can take advantage of, both to improve services and to reduce costs.
And new technology, specifically the so-called “4G” wireless networks being deployed by cellular carriers, can support wireless bandwidth services that are as much as ten times faster than previous networks.
