As part of the plan to launch two gig downstream bandwidth, Comcast is also rolling out higher upload speeds that range from 5x to 10x faster in 34 towns and cities by 2022’s end. Comcast has based these speed increases on the upstream through “mid-split” enhancements that will increase the spectrum allocated to the upstream.
