The two units combined rank 6 among all telcos globally based upon 3Q20 annualized revenues, and 12th if ranked by capex.

Comcast Cable US is a cable TV-centric telco, with a large fiber network in the core and a hybrid of fiber and coaxial cable (HFC) network near customer locations. In the last decade, Comcast has invested heavily to upgrade the capacity and functionality of this network, pushing fiber further to the edge and deploying faster access technologies (notably DOCSIS 3.1). Its broadband service speeds continue to get higher, requiring heavy investments in core capacity; Comcast claims that it doubles its network capacity in roughly 2.5 years. One example: it had 1700 100Gbps links to its core network in place in June 2020, from 500 100G links in March 2019.

Comcast's European unit, Sky, has a far different network. Its initial offering was a one-way satellite broadcast service. Over the last two decades, the company has gradually found ways to layer broadband Internet connectivity on top of this via a combination of fiber deployments, acquisitions, and local loop unbundling.
