mm-Wave FWA for Global Gigabit Access
Gigabit Broadband as a Universal Requirement
Access to high-quality broadband connectivity has become a fundamental requirement for modern societies. Economic growth, digital inclusion, public services, and innovation increasingly depend on reliable, high-capacity networks. Applications such as cloud computing, remote work, online education, telemedicine, ultra-high-definition video, and emerging immersive services demand not just basic connectivity, but consistent broadband speeds approaching or exceeding 1 Gbps.
While fiber-to-the-home (FTTH) is widely recognized as the gold standard for gigabit access, deploying fiber everywhere is neither fast nor economical. Civil works, rights-of-way, and long deployment timelines make universal fiber coverage difficult, particularly in suburban, rural, and rapidly expanding urban areas.
To bridge this gap, millimeter-wave Fixed Wireless Access (mmWave FWA) has emerged as a powerful and practical solution, capable of delivering fiber-like performance without the need for extensive physical infrastructure.
mm-Wave FWA and the Role of Area-Licensed Spectrum
The key enabler of reliable, high-capacity mmWave FWA is access to area-licensed spectrum. Unlike unlicensed or lightly-licensed bands, area-licensed mmWave spectrum provides operators with exclusive, interference-free access across a defined geographic region, enabling predictable quality of service and scalable network planning.
Licensed spectrum enables:
- Guaranteed, interference-free operation — critical for delivering consistent multi-gigabit speeds
- Long-term investment security — operators can plan and expand networks with confidence
- Regulatory compliance and accountability — essential for commercial service delivery
- Interoperability with 5G NR standards — enabling convergence with mobile network infrastructure
Area-Licensed mm-Wave Bands: A Global Resource
Europe: 26 GHz and 28 GHz
In Europe, the 26 GHz band (24.25–27.5 GHz) has been harmonized across EU member states as a primary band for both 5G mobile and FWA services. The 28 GHz band (27.5–29.5 GHz) is also increasingly used in several European markets, offering additional spectrum for high-capacity deployments.
North America: UMFUS and LMDS
In the United States, the FCC has allocated the 24 GHz (24.25–24.45 GHz and 24.75–25.25 GHz), 28 GHz (27.5–28.35 GHz), 37 GHz (37–38.6 GHz), 39 GHz (38.6–40 GHz), and 47 GHz bands for licensed mmWave services under the Upper Microwave Flexible Use Service (UMFUS) framework. Additionally, the Local Multipoint Distribution Service (LMDS) band at 28–31 GHz has historically been used for FWA and remains relevant in certain markets.
Global Trend: Migration to Flexible TDD
A notable global trend is the migration of mmWave FWA systems toward Time Division Duplexing (TDD) operation, consistent with 5G NR air interface standards. TDD offers operators flexible asymmetric traffic handling — allocating more capacity to downlink during peak consumption periods — while enabling harmonized equipment ecosystems across FWA and mobile markets.
Technological Advances Powering mm-Wave FWA
The latest generation of mmWave FWA systems incorporates several breakthrough technologies that dramatically improve performance, range, and spectral efficiency:
- Multi-User MIMO (MU-MIMO): Enables simultaneous transmission to multiple subscriber terminals, significantly increasing sector capacity and spectral efficiency
- Advanced Antenna Systems (AAS) with Hybrid Beamforming: Combines digital and analog beamforming to direct high-gain, narrow beams toward individual subscribers, improving link budget and reducing interference
- Carrier Aggregation: Combines multiple spectrum channels to deliver aggregate throughput exceeding 5 Gbps per sector
- 5G NR Compatibility: Alignment with 3GPP standards enables coexistence and integration with 5G mobile network infrastructure
Fiber-class FWA without Fiber-like constraints
mmWave FWA is suitable for:
- Suburban and rural areas where fiber deployment timelines and costs are prohibitive
- Urban multi-dwelling units (MDUs) where last-mile fiber connectivity within buildings is complex
- Enterprise campuses and business parks requiring high-speed, dedicated connectivity
- Rapidly growing residential areas where demand outpaces fiber rollout schedules
- Emerging markets seeking rapid broadband deployment at scale
Complementing Fiber and Outperforming Alternatives
Compared with alternative access solutions:
- vs. Sub-6 GHz FWA: mmWave provides significantly higher throughput (multi-Gbps vs. hundreds of Mbps) and supports denser subscriber deployments per sector
- vs. Unlicensed Wi-Fi: Licensed mmWave eliminates interference, offers guaranteed QoS, and supports carrier-grade SLAs
- vs. DOCSIS Cable: mmWave FWA offers symmetric gigabit speeds and rapid deployment without physical cable infrastructure
WiBAS™ G5 and the Future of Gigabit FWA
A concrete example of these advances is the WiBAS™ G5 solution, which delivers reliable multi-gigabit connectivity over distances exceeding 8 km. Designed for operation across all area-licensed mmWave bands, WiBAS™ G5 combines MU-MIMO capabilities, advanced MIMO, massive hybrid beamforming, and carrier aggregation to provide true fiber-like performance over wireless.
As regulators, operators, and technology providers align around licensed mmWave spectrum, mmW FWA is poised to play a central role in delivering global gigabit access — everywhere and to everyone.
