Do 5G providers need to own a fiber network too?
AT&T and Verizon – two of the nation's biggest 5G mobile network operators – own extensive fiber holdings around the country, and both argue that such ownership is critical to their long-term success. T-Mobile and Dish Network, on the other hand, are building extensive 5G mobile networks (though Dish hasn't yet switched on commercial services) without owning any fiber whatsoever. And, according to both Dish and T-Mobile, that's just fine. So, which side is right?
