The Wireless Broadband Alliance (WBA) has published a requirements framework, "6G & Wi-Fi Requirements – Enabling Seamless Connectivity Across 6G and Wi-Fi," that aims to put Wi-Fi inside 6G architectures from the first design stage rather than leaving it as a fallback access option after cellular blueprints are fixed.

The report's central premise is simple: ubiquitous connectivity, especially indoors, will depend on Wi-Fi and future cellular networks working together more effectively while each keeps its complementary strengths. The WBA, a global industry body whose members span operators, vendors and equipment makers, argues that no single wireless technology will satisfy every coverage, mobility, latency, reliability, ownership and cost requirement.

What does the framework actually require?

The WBA lays out a concrete technical checklist rather than a marketing vision:

• Multi-vendor interoperability
• Authentication and authorization
• Simplified signaling
• Enhanced security
• AI-enabled network recommendations
• Quality-of-service-aware traffic steering and switching
• User-centric mobility
• Energy efficiency
• Sensing capabilities

Crucially, the framework supports deployment models in which Wi-Fi traffic may be anchored inside or outside the cellular core. The WBA deliberately declines to prescribe a single cellular-centric architecture. That flexibility directly addresses why earlier Wi-Fi and cellular convergence initiatives stalled: high costs, complexity, fragmented responsibilities and limited commercial adoption.

Who gains if convergence works?

The WBA ties its requirements to commercial outcomes, not just architecture diagrams. For operators, the prize is more efficient use of Wi-Fi and cellular capacity, traffic offload, federated access and service-level-based offerings spanning mobile, fixed and Wi-Fi networks. Device makers would get more consistent approaches to authentication, mobility and network selection — a persistent pain point in multi-access devices today.

Enterprises could see simpler network operations and broader coverage options, while end users would experience fewer disruptions as devices move between access networks.

The framework also flags target verticals where predictable mobility, security, quality of service and cross-network visibility carry a premium: industrial automation, smart cities, connected vehicles, intelligent transportation, mission-critical communications, immersive applications and sensing.

Why should industrial buyers care?

Wi-Fi already carries the bulk of indoor enterprise and industrial connectivity, while cellular provides managed mobility, wide-area reach and policy control. A modular convergence model would let manufacturers, utilities, transportation operators and smart infrastructure providers combine both without forcing every deployment into the same architectural pattern.

The catch, as ARC Advisory Group notes in its analysis, is that convergence only pays off if it produces interoperable products, transparent policy control, end-to-end security and operational tools that give consistent visibility across domains. Standards alignment, implementation guidance, technical evaluations and trials will matter as much as the high-level architecture.

ARC recommends that industrial end users evaluate Wi-Fi and future cellular as complementary elements of a unified wireless strategy, with explicit requirements for indoor coverage, mobility, security, quality of service, lifecycle management and ownership. It urges network and automation suppliers to map their products against the WBA requirements, and it calls on standards organizations to use trials to surface architectural gaps early so Wi-Fi requirements are represented as 6G frameworks evolve.

What happens next?

The WBA framework is an early step, and its practical test will be conversion: whether the industry can turn these requirements into standards, interoperable implementations and deployment models that improve user experience without recreating the complexity that undermined earlier convergence efforts. For now, the document gives operators, vendors and device makers a common checklist to negotiate against as 6G standardization gathers pace.
