Triangle Transit customers may now surf the Web a little faster while killing time during a bus ride.

An upgrade from 3G to 4G Wi-Fi was completed on all 68 buses in the TTA system this month.

According to a TTA news release from Monday: “The better service represents part of a continuing campaign to bring technological advances to current customers, potential riders and public transit. “

Triangle Transit began offering free Wi-Fi to customers in 2011.
