I'm always amazed at how television in the field works. It's all magical really.
To broadcast on the #AOroadtrip, we're using a "jetpack." It's a computer in a backpack with half a dozen cellphone air cards. All those cards make a "tube" that funnels video and audio back to the station. As long as we have cellphone signal, we have a live signal. There's a delay, but the producers work hard at cutting that down during a show.
Along with the jetpack, we've got a camera (obviously) and microphones, tripod, light and a laptop. Normally, I'd be working on a set deadline, like 5p or 6p. During a long assignment, I work for several deadlines. First one is at Noon Thursday. After that shot, I assess what content producers want for the 4p, 5p, 6p and 10p shows. I'll shoot what video I need, feed it back (either over the jetpack or FTP) and email in scripts.
It's not glamorous, or easy sometimes, but it's a lot of fun! Working from the RV means I don't have to squat at a Starbucks (or really anywhere with free WiFi). Trust me, I've done it before. There's a hamburger place on the square in Franklin, TX, that I work out of anytime I'm going to be there longer than it takes to drive back. Solid food and free internet :)
