T-Mobile and Sprint filed public interest statements to the Federal Communications Commission today. The 700-page filing is part of the companies’ bid to merge, which they say will help them deploy a nationwide 5G network through a $40 billion investment.

Highly anticipated, 5G is the next generation of wireless technology that many tech companies are already working on. This version of 5G that both companies are discussing will be built on top of existing LTE networks, and it won’t be a standalone 5G network, which is still yet to come. Without the merger, both companies agree that they’ll eventually deliver 5G internet, but that the speed of development will be much slower.
