Many companies are looking at satellite as a way to deliver broadband to under served markets. The advantage to the low earth satellite fleet is that it can provide service to customers throughout the world. There are a number of firms looking to get into this space and it will be interesting as the technology emerges in the coming years. Not all of these firms will focus on direct to consumer needs as there are other applications such as smart cities, agriculture, self driving vehicles etc that will be targeted.
Since there will be numerous satellite your antenna will be designed to pick up the signal from the closes available bird and then will hand it off as that one goes out of range. Very cool stuff. It will likely be 3-5+ years before there is wide spread availability as there is quite a bit to do and regulations will likely be drafted in the coming years.
As to the question with space junk these satellites are designed to have a short life and will be de-orbited and burn up in the atmosphere.
Fixed satellite internet is also rapidly improving with the next generation of satellites launching in the next 18 months. These will be able to deliver significantly higher speeds and performance through large areas of the world.
