Businesses across Northern California, particularly in the Bay Area, rely on fast, secure, and reliable internet access for their daily operations. Whether supporting cloud platforms, AI workflows, automation systems, CRMs, or multi-office locations, connectivity has become the backbone of the modern enterprise. Yet many regions across the Bay Area and Central Coast still face limited fiber availability, lengthy construction timelines, and infrastructure that struggles to keep pace.

Fixed Wireless Access (FWA) has been a powerful solution to deliver high-performance broadband without the delays or the cost of trenching fiber. With thoughtful engineering, Etheric Networks’ FWA offering provides speeds and reliability that rival wired or satellite alternatives—backed by a robust fiber-based core network.

Etheric Networks has delivered high-performance wireless and fiber-backed broadband across Northern and Central California since 2003. Our network includes 400+ miles of dark fiber and more than 40 base stations, allowing us to serve businesses, public agencies, and communities with reliable, high-speed connectivity.

As a locally owned and independently operated provider headquartered in San Mateo, we prioritize security, service quality, and consistent performance. Our infrastructure is engineered to support modern business applications, multi-site operations, and fast deployment timelines.

How FWA Works

FWA replaces the “last-mile” cable with a secure wireless bridge. Instead of trenching to each building, Etheric installs an outdoor antenna that links to one of our nearby radio towers or rooftop sites.

The FWA Process

  • A high-capacity wireless signal is transmitted from an Etheric base station.
  • A fixed antenna at the customer’s location receives the signal.
  • The connection is encrypted and routed through Etheric’s fiber-backed network.
  • The customer gains high-speed broadband without disruptive construction.

This model enables rapid deployment of reliable service to offices, industrial zones, agricultural operations, construction sites, event venues, and even residential locations in harder-to-serve areas.

Why FWA Matters for Businesses

For enterprises, the biggest barrier to growth is often connectivity-related delay or uncertainty. FWA specifically addresses that by offering:

  • Rapid deployment for new sites or expansions
  • Speeds and latency suitable for cloud, automation, AI and mission-critical systems
  • Cost-effective reach into areas where traditional wired infrastructure is delayed or unavailable
  • Scalability through multiple spectrum and technology layers
  • Redundancy options for business continuity

Advanced Wireless Technologies Behind Modern FWA

Modern Fixed Wireless Access (FWA) relies on multiple wireless technologies that work together to deliver consistent performance in a range of environments. Etheric uses a multi-spectrum approach supported by a robust fiber network, enabling stable speeds, predictable latency, and reliable coverage even in challenging terrain. Below are the key technologies used in today’s deployments:

CBRS (3.5 GHz Spectrum)

CBRS enhances stability and performance in areas where traditional solutions struggle or where unlicensed bands are congested. With managed access layers, CBRS supports consistent speeds and higher user density—ideal for commercial parks, suburban businesses, and mixed-terrain deployments.

6 GHz Wireless

The 6 GHz band delivers more bandwidth and higher speeds than mid-band options, supporting medium to large business environments, multi-user deployments, industrial sites, and suburban commercial areas.

mmWave

Millimeter wave (mmWave) enables ultra-low latency and near-fiber-level speeds. This spectrum is well suited for enterprise campuses, multi-building operations, and dense urban or industrial zones where short-range, high-capacity links are required.

In partnership with BroadbandOne, we are deploying additional mmWave spectrum in Salinas, strengthening broadband performance for enterprise and industrial operations.

Tarana G1: Modern Wireless for Challenging RF Conditions

Tarana’s G1 platform is one of several advanced wireless systems used to improve performance in areas where traditional radios struggle; such as foliage, rolling terrain, dense suburban layouts, and environments with mixed or partial line-of-sight.

The G1 system uses large multi-antenna arrays, beamforming, and interference-rejection algorithms to maintain stable modulation rates even when the RF environment is noisy or variable. Many rely on Tarana’s RF planning tools, which model performance based on receive signal levels and realistic fading margins rather than optimistic assumptions. This approach allows us to predict achievable data rates with greater accuracy.

Tarana also includes self-interference and asynchronous burst interference cancellation, which help reduce the impact of neighboring radios in both licensed and unlicensed spectrum. While no system fully eliminates interference, these capabilities enable Tarana to operate as a noise-limited platform in many real-world scenarios.

In practical deployments, Tarana:

  • Improve link stability in mid-terrain and cluttered suburban environments
  • Maintain performance where higher-order modulations are difficult for standard radios
    Increase capacity on existing tower infrastructure
  • Deliver service faster than fiber construction in remote or hard-to-reach locations

Why a Layered Spectrum Strategy Matters

Each spectrum band plays a distinct role:

  • Low-Band: Longer reach, reliable coverage: ideal for wide areas
  • Mid-Band (CBRS / 6 GHz): Balanced speed and coverage, excellent for many business sites
  • High-Band (mmWave): High capacity, ultra-low latency: for enterprise and industrial zones

Etheric’s approach integrates all required layers and backs them with fiber, ensuring dependable performance across terrain and business use-cases.

What Sets Etheric Networks Apart
