The EVDO Rev B Modem driver is a software component that allows your Windows computer to communicate with a device using EV-DO Revision B (Evolution-Data Optimized) technology. This technology is used primarily for mobile broadband (cellular) modems, providing high-speed internet access over cellular networks, such as Verizon, Sprint, or other mobile carriers.
EVDO Rev B is an upgraded version of the previous EVDO technology, offering faster data speeds for internet browsing, video streaming, and other data services over 3G networks. The modem could be either a USB dongle, a PC card, or built into a mobile hotspot device.
