What are EVDO and 1XRTT?

Contact us

Mobile network technology is constantly being improved, primarily to let you send and receive data faster.

EVDO (Evolution Data Optimized) is an evolution of the CDMA (code division multiple access) wireless standard. It’s the most prevalent 3G mobile network across North America. 1XRTT is a slightly earlier technology.

Further network technology evolutions after 1XRTT and EVDO include HSPA and HSPA + (4G). Bell uses all these technologies in our networks, although different networks are available in different areas.
