FTTP is moving from field trials and the lab to the real world, and it's happening in Keller first," Network Services Group President Paul Lacouture said at a news conference with city officials in Keller today. "This technology will transform our network and the products we will be able to offer to consumers and businesses. Once deployed, for example, the slowest broadband connection we'll offer customers will be three times as fast as broadband speeds commonly available today. In short, we are building a new network that will make us the broadband leader in the 21st century."
Bob Ingalls, president of Verizon's Retail Marketing Group, said, "We expect to initially make available a range of broadband access products that will feature download speeds of 5 megabits per second, 15 megabits per second, and 30 megabits per second. These services will be provided at substantial value over anything that's in the market today -- highly competitive pricing because we know that's what customers will expect."
Just to compare 1.5(t1) is 1 1/2 megabits per second
