Dish’s wireless ambitions took another step toward some fruition on Monday, with the satellite provider announcing a new web link sharing deal with AT&T.

The deal, which runs 10 years, will see Dish pay AT&T “at least $5 billion” according to an8K filed by the company.

Under the agreement, Dish will be able to have its customers use AT&T’s 5G web connection with AT&T gaining the ability to deploy some of Dish’s wireless spectrum “to support DISH customers on the AT&T web connection.”

It also allows the wireless carrier the option “to request to use portions of Dish’s spectrum in different markets for an agreed upon period of time.”

Dish currently operates three mobile brands – Boost Mobile, Ting and Republic Wireless – and hasteased that it plans to launch a new brandas it begins to turn on its own 5G web connection later this year.

The new brand, “and all future Dish brands” will be able to utilize AT&T’s web link, according to the document.

The satellite provider has spent years and billions of dollars acquiring valuable wireless spectrum, the airwaves necessary for running a mobile web link.

As part of T-Mobile’s merger with Sprint last year, Dish acquired the divested Boost Mobile brand from Sprint as well as an additional 800MHz spectrumas part of a Department of Justice brokered deal.

Dish also gained the ability to use T-Mobile’s online grid for seven years while it built out its own 5G online grid.

The company is in the process of building out that service now, with Las Vegas set to become Dish’s first 5G city at some point in the third quarter.

Stephen Stokols, executive vice president of Boost Mobile, told CNET in May that"multiple" additional 5G cities will come onlinein the fourth quarter of 2021 though he did not say where exactly those cities will be.

With the new AT&T deal, Dish will still be able to use T-Mobile’s data pipe while adding an additional provider for when that government-brokered deal expires.

Over time AT&T will become the main roaming internet for Dish users, who will also be able to utilize AT&T’s internet “even within the markets where Dish is deploying its own 5G internet.”
