Times technology writer Salvador Rodriguez is at the Coachella Music and Arts Festival, testing apps and smartphones in between catching sets.
One of the things Rodriguez will be keeping tabs on is how good cell service is at the festival. Verizon, AT&T, T-Mobile and Sprint are all trying to make a good impression with their customers there.
The four major wireless carriers say they're going out of their way to make sure there is enough network capacity for their customers to make calls, send texts and upload photos and videos to their social networks.
Another thing he'll be testing is Shazam, an app that helps you identify songs you're listening to.
Among the gear he's bringing are several smartphone chargers, because the lines at cellphone charging stations are likely to be long.
And you can't work if your battery is dead.
