That will change soon. The internet will come though the wireless towers. If you have a weak wireless signal, then all you will need is a repeater in the house.
There are also digital antennas. It’s just a USB you plug into your TV. Some of them can pull a digital signal from 100 miles. The beautiful thing about digital antennas is that you either have a great picture or no picture at all.
The issue isn't so much the technology, it's the pricing.I have family getting their internet via wireless now, and while it's only 4g it's adequate for their needs. The problem is it costs $100/month for 10gb of data, and AT&T & Verizon have almost identical pricing.
Compare that to the unlimited, higher speed data available to me via cable for $49/mo.
