Lower Sioux Indian Community
In April 2017, Mediacom announced that they upgraded their customers on the Lower Sioux Reservation to their Gigabit access. Those upgrades are likely represented in the stats above. And looking at the map, it appears as if the served area is in Renville County, which would be RS Fiber territory.
Clearly there is work to be done in the Lower Sioux but the good news is that the broadband they have is good broadband; they are not building broadband that will only be sufficient to meet the 2022 speed goals. They appear to be moving toward the future.
The Lower Sioux was able to participate in Blandin Broadband Community (BBC) project through a partnership with Redwood County.
