(Telecompaper) Dish Network is moving forward with its plans for what it says will be the first standalone 5G broadband network in the US. The company has released a new Request for Proposal (RFP), its third, for different elements of the 5G national network. Dish has said it wants its standalone 5G broadband to be available for at least 70 percent of the US population by June 2023, conditional on the successful merger of T-Mobile US and Sprint.
