Fixed Wireless Access Net Additions: Measuring FWA Broadband Growth

Fixed wireless access net additions measure the net increase or decrease in broadband connections delivered over a carrier's wireless network during a period.

A simplified formulation is:

1FWA Net Additions
2≈ New FWA Broadband Connections
3- FWA Broadband Disconnects
4± Issuer-Defined Adjustments

FWA uses radio spectrum and wireless network capacity to provide fixed internet service to a home or business. It is broadband growth, not mobile-phone subscriber growth.

FWA net additions are not wireless phone net additions

The same carrier can use its wireless network for very different products.

Postpaid Phone Net Additions measure the net change in phone customers or connections. FWA net additions measure fixed internet connections using cellular radio access.

T-Mobile includes 5G broadband customers inside broader postpaid or prepaid customer categories, while still disclosing broadband net additions separately. Verizon separately reports FWA broadband connections and net additions.

Without preserving those classifications, an analyst can accidentally double count growth across headline customer metrics.

FWA and fiber growth should be separated

Fiber Net Additions and FWA net additions can both contribute to total broadband growth, but they rely on different network economics.

FWA growth can depend on:

• available spectrum;
• radio-network capacity;
• cell-site density;
• congestion management;
• customer-premises equipment;
• address eligibility; and
• mobile traffic demands competing for the same network resources.

Fiber growth depends more directly on physical network construction and serviceable locations.

A single total broadband net-add number can therefore hide materially different capital and capacity tradeoffs.

Capacity matters more than the subscriber count alone

A carrier may have strong FWA demand but choose to limit address availability in congested areas.

That makes the relationship between FWA subscribers and economics different from a purely unconstrained software product. Adding customers can monetize otherwise unused network capacity, but the incremental economics can change as local capacity tightens.

T-Mobile has described a fallow-capacity approach to broadband growth. Verizon and AT&T also discuss spectrum and network capacity in connection with FWA expansion.

Acquisitions and classification changes can distort growth

Ending FWA connections may not equal beginning connections plus organic net additions if the company acquires a base, changes product classifications, or makes other adjustments.

AT&T's 2026 operating data also excludes specified acquisition-related activity and certain regulatory-driven disconnections from its reported internet net-add comparison, illustrating why scope notes matter.

A simple example

Suppose a carrier activates 500,000 new FWA broadband connections and loses 180,000 during the quarter:

1500,000 new FWA connections
2- 180,000 disconnects
3= 320,000 FWA net additions

That says the FWA subscriber base expanded by 320,000 before other adjustments. It does not reveal service revenue, margin, capacity consumption, or customer acquisition cost.

Broadband mix can change the interpretation of growth

AT&T reported 646,000 total consumer and business internet net additions in the second quarter of 2026, including 367,000 fiber and 279,000 fixed wireless. The combined number shows total connection growth, while the split reveals the underlying network mix.

Verizon reported millions of FWA broadband connections and separately defined FWA net additions as new FWA connections less disconnects. T-Mobile reported 5G broadband net customer additions within broader customer categories.

Filing examples

AT&T's second-quarter 2026 data reported 279,000 fixed wireless net additions. Verizon's filings define FWA broadband connections and FWA net additions explicitly. T-Mobile's 2025 Form 10-K disclosed 5G broadband net customer additions and ending broadband customer counts.

Bottom line

Fixed wireless access net additions measure net broadband connection growth over a wireless network, not phone subscriber growth or fiber growth. Preserve product classification, postpaid/prepaid treatment, capacity context, acquisitions, exclusions, and disconnect methodology before comparing carriers.
