Oregon’s Day Wireless Systems goes global with takeover of Ireland’s Sigma Wireless Communications

Day Wireless Systems, a major player in critical communications technology, has announced the acquisition of Sigma Wireless Communications Limited, a wireless solutions provider headquartered in Dublin, Ireland. The deal significantly expands Day Wireless Systems’ international operations and strengthens its presence in European markets as part of its long-term global growth strategy.

The strategic acquisition, completed with support from legal and financial advisors on both sides, signals a notable consolidation in the wireless communications industry. It aligns with Day Wireless Systems’ ambition to deliver mission-critical communications solutions across an expanded geographical footprint, including North America, Europe, and other international markets.

Why did Day Wireless Systems acquire Sigma Wireless Communications?

Day Wireless Systems has steadily built a reputation for providing dependable and customized communications solutions to a diverse set of industries such as public safety, utilities, transportation, and enterprise. Headquartered in Milwaukie, Oregon, the company has operated for more than 50 years, offering services that include two-way radio systems, broadband wireless, dispatch infrastructure, and security services.

The acquisition of Sigma Wireless Communications is designed to complement these offerings by integrating Sigma’s deep expertise in radio communications, public safety networks, and broadband wireless deployments. Sigma has been a core part of critical infrastructure projects in Ireland and beyond, often supplying secure and resilient communications for emergency services and public sector clients.

Day Wireless Systems’ CEO Lane Falkner described the acquisition as a “significant milestone” in the company’s expansion plans. He indicated that Sigma’s strong operational capabilities and international project experience would reinforce Day Wireless Systems’ value proposition across new markets.

How does this acquisition impact customers and employees?

Both companies emphasized a customer-first approach during the integration phase. Day Wireless Systems confirmed that Sigma Wireless Communications will continue operating with its existing personnel and infrastructure, ensuring continuity for clients and stability for employees.

In a joint statement, the companies reiterated their commitment to minimizing disruption and maintaining high standards in ongoing projects. Lane Falkner highlighted that the merger would allow both companies to “offer unparalleled solutions and support” across global markets.

Sigma’s leadership echoed this optimism. CEO Ian McCullagh stated that Day Wireless Systems’ values aligned with those of Sigma Wireless and that the acquisition would “provide the resources and scale to further enhance our offerings.” Chairman Tony Boyle added that the move validated years of work building a customer-focused company and would open new pathways for innovation and delivery of mission-critical solutions.

What strategic value does Sigma Wireless bring?

Sigma Wireless Communications has built a strong presence in the Irish market, notably in the design, integration, and support of communications networks for public safety and government clients. The company’s portfolio includes radio access networks, command and control systems, and broadband connectivity deployments tailored to urban, rural, and critical infrastructure environments.

The acquisition adds geographic and technological depth to Day Wireless Systems’ portfolio. With Ireland serving as a European foothold, Day Wireless Systems can now directly access EU markets while leveraging Sigma’s existing relationships and regulatory knowledge.

This strategic presence is particularly important as wireless infrastructure modernisation and digitalisation of emergency communication networks gain momentum globally. Governments and public sector agencies are accelerating procurement of resilient and redundant communication systems, particularly in light of extreme weather events, geopolitical tension, and cyber risks.

Who advised the deal?

The acquisition was supported by several professional advisors. Sigma Wireless Communications received corporate finance advice from Clearwater International, legal counsel from Bowler Geraghty, and financial and tax diligence support from Forvis Mazars.

Day Wireless Systems was represented by international law firm Taylor Wessing and received financial and tax diligence assistance from Crowe Ireland.

What does this mean for the wireless communications market?

The acquisition of Sigma Wireless by Day Wireless Systems is the latest example of strategic consolidation within the wireless and mission-critical communications sector. As technology convergence accelerates—integrating broadband, LTE, AI-driven monitoring, and cloud dispatch systems—providers are seeking to broaden their geographic coverage while integrating vertically.

For customers, this trend may mean more end-to-end offerings, streamlined procurement processes, and increased investment in support infrastructure. For competitors, it places added pressure to scale their operations or risk being marginalised in cross-border contract awards.

Industry analysts view the move as a logical expansion for Day Wireless Systems, particularly as demand grows for smart cities infrastructure, next-gen public safety communications, and broadband-for-emergency-use services. The Irish market, which has increasingly prioritised digital transformation in public services, presents strong medium-term growth potential.

Expert insights: Why scale and international presence matter now

Industry observers note that cross-border acquisitions in the communications sector are increasingly driven by demand for integrated, scalable solutions. Legacy radio systems are being upgraded to digital platforms with LTE and 5G backbones, especially in sectors such as law enforcement, utilities, and transportation.

Experts believe that Day Wireless Systems’ move to acquire a local leader like Sigma Wireless gives it more than just geographic access—it brings regulatory familiarity, experienced personnel, and a live customer base ready to upgrade to next-gen systems.

With Sigma Wireless already operating over 300 large-scale systems in Ireland and adjacent markets, the integration provides Day Wireless Systems with immediate scale and credibility.

This deal also aligns with global trends toward strengthening critical infrastructure amid rising concerns over emergency preparedness, data security, and communication reliability during extreme events.

A step toward global leadership in mission-critical communications

The acquisition marks a transformative step in Day Wireless Systems’ growth journey, signalling its intent to become a leading global provider of end-to-end communication solutions. By acquiring Sigma Wireless Communications, the company is not only strengthening its presence in Europe but also positioning itself to deliver large-scale, integrated communication systems across continents.

In a sector increasingly defined by resilience, digital transformation, and interoperability, Day Wireless Systems is betting that international scale and deep integration are the key to long-term success.
