Anterix Inks Contracts Worth $10.9M, Including First 5x5 MHz Deal

Why It Matters

The contracts demonstrate rapid utility adoption of 900 MHz private wireless, a technology that can boost grid resilience and accelerate the industry’s digital transformation.

Key Takeaways

• Anterix secured $10.9M in utility contracts this month
• NorthWestern Energy's deal includes first 5×5 MHz 900 MHz spectrum usage
• TNMP will start with 1.4 MHz, expanding to 3×3 MHz later
• Utilities aim to improve wildfire detection and remote line control
• 900 MHz band offers long-range, reliable connectivity for rugged terrain

Pulse Analysis

The Federal Communications Commission’s recent amendment expanding the 900 MHz band from 3×3 MHz to 5×5 MHz has opened a new frontier for private wireless networks. Because the spectrum sits lower in the radio frequency range, it penetrates foliage and terrain better than higher‑frequency bands, delivering reliable, long‑range links that are ideal for utility infrastructure spread across rural and mountainous regions. Industry analysts have long touted the band as a cost‑effective alternative to leased fiber or microwave, especially as grid operators seek to digitize assets and meet stricter reliability standards.

Anterix capitalized on the regulatory shift by closing $10.9 million in contracts with Texas‑New Mexico Power and NorthWestern Energy. The NorthWestern agreement is notable for being the first to lock in the full 5×5 MHz allocation, though delivery will begin with a 3×3 MHz slice before the larger block becomes available. The utility plans to use the extra capacity for real‑time monitoring of distribution lines, early wire‑fire detection, and enhanced situational awareness in wildfire‑prone zones. TNMP’s phased 1.4 MHz to 3×3 MHz rollout supports its 2025‑2027 resiliency plan, promising faster outage response and scalable communications.

The deals signal a broader shift toward dedicated, utility‑controlled wireless backbones, a model that could soon extend beyond energy to transportation, water, and public safety agencies. Anterix’s hint at adding a satellite component suggests a hybrid architecture that would blend terrestrial coverage with space‑based redundancy, further de‑risking critical communications. Competitors such as Crown Castle and American Tower are watching closely, as the 900 MHz niche may become a battleground for spectrum‑as‑a‑service offerings. For investors, the momentum underscores a growing revenue stream tied to the nation’s grid modernization agenda.
