A private telecommunications company wants to introduce Wi-Fi service to a couple of New York City area train lines. Mobilitie currently operates the free Wi-Fi service NYFI, and has submitted a proposal to build a wireless network for the Metro North and Long Island Rail Road lines. This service will no doubt be free to riders, and will be built and supported solely by revenue from ads. With many folks spending more and more time outside of the office, working while traveling is an option not to be scorned at, and with cloud computing applications getting more and more prevalent these days, it makes perfect sense to be able to go online on a train during your daily commute, even if it is just to tidy up a simple document.
