Ericsson Wins AT&T 600MHz

AT&T is reshaping its network by swapping out Nokia for Ericsson, rolling out new 600 MHz radios to boost coverage in hard-to-reach rural and indoor areas. After spending $23 billion on spectrum, they’re betting that these upgrades—plus uplink-enhancing tech for better video, IoT, and AI performance—can drive premium growth and fight customer churn. But here’s the catch: while open RAN was supposed to give carriers bargaining power with multiple vendors, doubling down on Ericsson could mean less leverage and more risk if something goes wrong.

Meanwhile, Comcast is playing a tricky numbers game with its wireless business. Wireless revenue is up and more customers are choosing premium unlimited plans, yet most of the growth comes from free lines that could hit profits if they don’t convert to paid soon. For now, Verizon—the network behind Comcast’s wireless—reaps wholesale fees without the promo risk. If too many customers stick to free deals or don’t upgrade, Comcast’s margins will stay under pressure.

And just as reliability becomes a selling point, Verizon faced a major outage and fiber sabotage, raising fresh questions about network resilience. SpaceX’s Starlink is gearing up for a bigger role in U.S. mobile with next-gen satellites and spectrum, potentially offering backup in emergencies—if they clear regulatory and technical hurdles first. Featuring insights from AT&T, Comcast, Verizon, and T-Mobile.
