What Are Comcast Internet Speeds?
Many consumers want the highest speed from their Internet service provider (ISP). Speed matters, especially when you're downloading memory-intense videos, photos and music. Comcast, a national company, provides Internet service in a variety of speeds to match your budget and online needs.
Comcast is one of the leading communications companies in America. Founded in 1963 as a basic cable business, it has evolved with the burgeoning technology. Listed on the Nasdaq stock exchange, Comcast Cable is one of the nation's largest cable television, video, high-speed Internet and phone providers for residential and business customers, as of 2011. Comcast also owns NBC Universal, which operates entertainment and news cable networks, local television station groups, a major motion picture company and theme parks.
Comcast offers various levels of residential high-speed Internet services, grouped in tiers according to speed. They are based upon kilobits per second (kbps) or megabits per second (Mbps) transmission rates for uploading and downloading of data. A kilobit is 1,000 bits of data; a megabit equals 1,000 kilobits, or 1 million bits. Comcast Economy offers a downstream rate of 1,500 kbps (1.5 Mbps) and an upstream rate of 384 kbps. Downstream refers to downloading data from the Internet, while upstream refers to uploading data to the Internet. Economy Plus has a download rate of 3,000 kbps (3 Mbps), with an upload rate of 768 kbps. Performance Starter provides a download rate of 6,600 kbps (6.6 Mbps) and an upload rate of 1,100 kbps (1.1 Mbps). Performance Plus offers a download of 8,800 kbps (8.8 Mbps), with an upload speed of 2,200 kbps (2.2 Mbps). Blast, the fastest speed, boasts a download rate of 17,600 kbps (17.6 Mbps) with an upload speed of 2,200 kbps (2.2 Mbps).
Comcast offers four levels of extremely fast service for businesses. These rates are measured in terms of megabits per second (Mbps). A starter plan has a downstream rate of 12 Mbps, with an upstream rate at 2 Mbps. The premium plan has downstream rate of 22 Mbps and an upstream of 5 Mbps. Deluxe offers a downstream rate of 50 Mbps, with an upstream of 10 Mbps. Deluxe 100 is the fastest speed, offering a downstream rate of 100 Mbps, with an upstream of 10 Mbps.
This service should be called "power boasting," as it features very high-speed downstream and upstream rates. Powerboost is a patent-pending Comcast network technology that enables consumers to experience faster connection speeds while downloading and uploading very large files. It provides a speed boost to the first 20 MB of data you are downloading and the first 10 MB you are uploading. This feature is included for free with Comcast's 6 Mbps, 8 Mbps, 12 Mbps, 16 Mbps and 22 Mbps plans. The fastest speed of 22 Mbps requires a highly specialized burst transmission modem called a DOCSIS 3.0.
