As part of their effort to get 5G launched in some markets in 2019, Sprint is making updates to their backhaul network. A recent SEC filing made it clear that Sprint is taking efforts to improve its backhaul capabilities in anticipation of 5G, including canceling some existing Ethernet contracts so that they can make changes, and they have also filed an application with the FCC asking for permission to widen its transmissions into additional portions of the 2.5GHz band. Sprint is heavily invested into 5G and is primed to launch their service in 9 cities this year: Atlanta; Chicago; Dallas; Houston; Kansas City; Los Angeles; New York City; Phoenix; and Washington, DC.
