After the rollout of LTE/4G networks, the potential for cellular networks to replace traditional wireline broadband emerged as a serious consideration. Fast forward to 2023, and nearly 60% of the world’s population—around 5 billion people—access the Internet over mobile networks. While wired networks still dominate in delivering reliable, high-speed broadband for residential and business use, Fixed Wireless Access (FWA) is now a game-changer, particularly when paired with SD-WAN.

The Rise of Fixed Wireless Access

FWA has emerged as one of the fastest-growing—and most profitable—segments for Internet Service Providers (ISPs). Industry Research reports that the global FWA market surpassed $140 billion in 2023 and is expected to grow annually at a rate of nearly 20% through 2030. Mobile operators have already embraced FWA as their second-largest use case after mobile broadband. Why?

FWA subscribers consume significantly more data—10 to 18 times that of a mobile subscriber.
They deliver double the revenue per subscriber compared to mobile broadband customers.

FWA has effectively shifted from being a supplementary service to a viable alternative to wired connections, offering speeds comparable to fibre through advancements in 5G and wireless radios. Yet, for businesses, FWA alone cannot consistently meet enterprise-grade requirements for uptime, reliability, and performance. This is where SD-WAN unlocks the full potential of FWA, enabling Managed Service Providers and businesses to truly capitalise on this opportunity.

Why FWA Alone Isn’t Enough

Early FWA deployments offered modest speeds of around 50 Mbps, suitable for basic use cases but insufficient for enterprise environments. Today, 5G-enabled FWA delivers Gigabit speeds—comparable to fibre—but challenges remain:

Inconsistent Quality of Experience (QoE): Packet loss, latency, and jitter can degrade application performance.
Business SLAs: Businesses require reliable connectivity for critical operations, edge computing, and branch applications.
Network Management: FWA alone lacks real-time traffic management intelligence, leading to underutilisation of bandwidth and performance bottlenecks.

To address these challenges, ISPs must complement FWA with SD-WAN—a software-defined overlay network that provides intelligent traffic management, optimised performance, and multi-path connectivity.

The SD-WAN Advantage for FWA

Combining FWA with SD-WAN creates a powerful solution for businesses, providing the flexibility, reliability, and quality needed for primary or secondary connectivity at branch offices and edge locations.

1. Intelligent Traffic Handling for Maximum Performance

Fusion's SD-WAN brings advanced traffic-handling capabilities to FWA deployments:

Dynamic QoS Management: SD-WAN intelligently maps users and applications to specific quality-of-service (QoS) tiers. This ensures critical applications such as voice, video conferencing, and AI workloads receive priority while less important traffic is deprioritised to conserve bandwidth.
Traffic Bonding: Fusion's bonding technology combines multiple network links—including FWA, satellite, and broadband—into a single, high-performance connection. This mitigates packet loss, latency, and jitter, delivering a superior user experience for real-time applications.

For example, last-mile remediation techniques in Fusion’s SD-WAN have been proven to improve call quality in FWA links, ensuring crystal-clear voice and seamless video conferencing.

2. Multi-Access Connectivity for Branch & Edge

Modern businesses rely on multi-access solutions to meet their connectivity needs. Fusion's SD-WAN enables enterprises to seamlessly integrate multiple access types—FWA, 5G/LTE, broadband, MPLS, and satellite—into a single intelligent overlay. This unified network architecture delivers:

High Reliability: Automatic failover ensures uninterrupted connectivity during link degradation or outages.
Cost Efficiency: Managed Service Providers can offer flexible connectivity options, combining FWA with wired networks to meet SLAs while reducing capital expenditure on fibre deployments.
Optimised Edge Performance: SD-WAN intelligently routes traffic to the best-performing link in real time, improving application responsiveness for edge and branch locations.

3. Accelerating ISP Monetisation of FWA

For ISPs, combining SD-WAN with FWA presents a significant revenue opportunity:

Lower CAPEX, Higher Reach: FWA allows operators to expand their broadband footprint at a fraction of the cost of fibre deployments. By offering SD-WAN-enabled FWA, ISPs can attract businesses looking for primary or secondary connectivity solutions.
Enhanced SLAs: SD-WAN’s dynamic traffic optimisation, failover capabilities, and bonding technologies empower ISPs to deliver premium SLAs that rival traditional fibre or MPLS networks.
Competitive Differentiation: With Fusion’s SD-WAN, ISPs can offer superior QoE, ensuring high performance for AI, video, and other demanding applications over FWA links.

A Growing Opportunity for ISPs & Enterprises

The demand for reliable, high-speed connectivity is driving unprecedented growth in the FWA market. According to GSMA, 131 operators in 64 markets launched FWA services in 2024 alone. By 2030, the number of FWA connections is expected to surge by 358%, reaching over 79 million connections worldwide.

However, the ability to consistently deliver enterprise-grade QoE and SLAs remains a critical differentiator. Fusion’s SD-WAN empowers ISPs to offer FWA with unmatched reliability, creating opportunities to:

Enter new markets with flexible, high-performing connectivity solutions.
Offer multi-access services combining FWA, wired broadband, satellite, and MPLS.
Deliver premium SLAs to enterprise customers, maximising profitability and customer retention.

Wrap | Unleashing the Full Potential of FWA with SD-WAN

Fixed Wireless Access is no longer a secondary or hypothetical option—it is a critical enabler of connectivity for both residential and enterprise markets. However, the key to unlocking its full potential lies in SD-WAN. By combining FWA with Fusion’s SD-WAN, ISPs can deliver superior performance, multi-path reliability, and enterprise-grade QoS—turning FWA into a viable alternative to traditional wired connections.

For ISPs and enterprises, this is a huge opportunity to expand reach, optimise performance, and drive profitability with a flexible, future-proof solution. Fusion’s SD-WAN provides the perfect platform to deliver next-generation FWA services, enabling businesses to thrive in an increasingly connected world.
