A source at cable service provider Comcast says the company is making improvements to its Internet service that will provide 20 percent of its subscribers with 100Mbps download speed by the end of the year. Enhancements to the company's existing DOCSIS 3.0 modems and cable systems make the higher data transfer rates possible, according to BBR. Comcast has already upgraded 90 percent of its coverage area to get the option of 50Mbps download speeds but has only rolled out 100Mbps in a single market.
