Comcast has just released some new details about its future-ready answer to Google Fiber and Verizon FiOS. Beginning in the first half of the year, Atlanta and Nashville will be the first cities to take advantage of a new technology that enables gigabit speeds over traditional cable connections.
What sets Comcast's new offering apart from the competition is that it relies on an upgrade of existing cable technology, rather than requiring a shift to expensive high-speed fiber optic cables, which are made of glass and transmit data as pulses of light. In other words, rather than building a whole new fiber infrastructure like Google Fiber is doing, Comcast can take advantage of the cables that are already in the ground to provide gigabit speeds. This is good for Comcast, because it means offering a similar service as Google's but at a lower upfront cost to itself; whether it means those savings will be passed on to consumers is another question.
Here's the catch: Customers who sign up for the service will have to swap their cable modems for new ones that support the fresh tech, known as DOCSIS 3.1. You can keep your existing modem if you prefer not to sign up for the gigabit service.
Comcast won't say just yet how much its gigabit cable service will cost. But we can guess.
The company does operate a fiber optic Internet service of its own, called Gigabit Pro. That offering enables speeds of up to 2 Gbps, or 2,000 Mbps. For that, Comcast charges $300 a month, in addition to installation fees.
In light of the gigabit cable service's slower download speed, it's probably safe to predict that Comcast will be charging subscribers somewhat less.
