Currently we can have DSL with a possible download speed of 6 Mbps or cable which claims 15 to 20 Mbps depending on which of the more popular plans you have and how much traffic there is on the cable. Upload speeds are usually much slower for both types of service.
Greenlight is a new fiber-optic service which is slowly growing in the area. Their basic service is for a 100 Mbps download speed currently priced at $50. They also offer a 1,000 Mbps service for $250 per month. Time Warner is responding with a 100 Mbps service priced at $65.
Where Greenlight expand next depends on how many people sign up in a particular area and the cost of building out to that area.
