AT&T has leased 55 spectrum licenses in the 3.45GHz band from N Squared II to expand its network capacity in approximately 12 states. The deal, which remains subject to FCC regulatory approval, grants AT&T de facto usage rights while N Squared retains legal control.
Why it matters
This move aims to improve network throughput, decrease latency, and accommodate higher user volumes by leveraging existing cell site infrastructure. It follows a significant industry trend of spectrum acquisition to meet growing demand for mobile data connectivity.
AT&T secured access to 3.45GHz spectrum across 25 markets, which will be integrated into the carrier's existing radio equipment at current cell sites. This deployment model avoids the need for new hardware installations to realize the bandwidth gains.
The players
AT&T
A major American telecommunications provider maintaining a large-scale cellular network and mobile data infrastructure.
N Squared II
A private venture firm backed by Northwood Ventures that manages and holds regulatory control over wireless spectrum licenses.
Northwood Ventures
An investment firm providing financial backing for various private ventures, including entities focused on spectrum holding.
The details
The arrangement functions as a spectrum manager lease where AT&T obtains operational control over frequencies owned by N Squared, a private venture backed by Northwood Ventures. By utilizing existing radio hardware at current sites, the carrier aims to integrate the 3.45GHz mid-band spectrum without major site upgrades. The capacity boost is intended to optimize network performance metrics, specifically throughput and latency, by increasing the available frequency headroom for mobile data traffic.
Timeline
In 2026, AT&T finalized a $23 billion spectrum acquisition from EchoStar.
In September 2026, AT&T announced the formal spectrum leasing agreement with N Squared.
The Tech Race
This lease follows the precedent set by the 2026 $23 billion EchoStar spectrum deal, illustrating how major carriers prioritize mid-band assets to stay competitive. It represents a tactical expansion of network resources as AT&T continues to scale its 5G and mobile data capabilities against regional and national peers.
Users in the 25 covered markets may experience improved mobile data speeds and lower latency once the new spectrum is fully integrated into existing towers. The timeline for these performance enhancements depends on the pace of the ongoing FCC regulatory approval process.
The takeaway
This transaction highlights the ongoing strategic reliance on leasing mid-band airwaves to satisfy escalating mobile data requirements. Readers should monitor future FCC filings and AT&T network status updates to confirm when the new spectrum becomes active in specific markets.
