Definition: Xfinity


TV, Internet, voice, security and cellular services from Comcast, Philadelphia, PA, http://corporate.comcast.com. Branded Xfinity in 2010, for decades Comcast was known for its cable TV service, which began in 1963 as American Cable Systems. Because the same coaxial cable that brought TV into the home and office is also used for Internet access, Xfinity became the largest ISP in the U.S.

Xfinity Services
X1 is the Xfinity cable TV platform, which includes regularly scheduled shows and movies along with third-party TV, news and streaming channels. Xfi is Comcast's mesh Wi-Fi, which distributes a hotspot throughout the home or office. Xfinity voice offers landline telephone service to analog phones by converting digital signals to analog. Xfinity Home provides in-home security monitoring, and Xfinity Mobile is cellular service.

Xfinity Mobile
Offering "quadruple play" in 2017 (TV, Internet, landline and cellular), Comcast introduced its cellular service as a bonus to Xfinity customers. Riding on the Verizon network, Xfinity Mobile charges customers per gigabyte of cellular data but does not charge a fee per phone line as do all other cellular providers. In addition, Xfinity Mobile customers automatically connect to the millions of Xfinity hotspots in public venues as well as in homes with Xfinity routers that have the default guest access turned on.
