It’s not surprising that 22 years after Verizon promised to deliver fiber to all of its service area in PA, millions still have only DSL or wireless. Neither DSL (0.5-15Mbps) or LTE (5-12Mbps) currently meet the definition of broadband (25 Mbps) and wireless comes with higher initial costs and monthly bandwidth limitations.
It all comes down to the lack of competition. Areas where Google installs its Google Fiber experience an overall improvement in speed and cost. But Google has been selective in rolling it out so there remains a lot of areas with only one viable choice.
