Industrial Wireless Bridge Complete Guide: YNW Full Series Deep Dive (1km to 300km)

Introduction

Industrial wireless bridges are the backbone of modern industrial comms. Factory automation, mine communications, oil field monitoring, smart grids, rail transit, ports, video surveillance, rural broadband — whenever running fiber is too expensive, takes too long, or is a maintenance nightmare, wireless bridges step in as the “air highway” connecting critical assets.

YNW full lineup spans 1-300km range, 5GHz/6GHz dual-band, 500Mbps-1.5Gbps throughput via PtP (Point-to-Point) and PtMP (Point-to-MultiPoint) topologies. This guide covers the entire product architecture, tech specs, selection logic, and deployment playbook — built for engineers who need real answers, not marketing fluff.

• PoE power: Single Ethernet cable carries data + power. 24VDC passive PoE or 802.3af/at active PoE.
• 2.4GHz independent management radio: Most models include a separate 2.4GHz radio for wireless Web config within 20m — no climbing the tower just to configure.
• Proprietary transport protocols: RapidFire runs W-Jet V, YNW series runs iPoll 3 — each optimized for its target topology.
• Infinity central management: Unified NMS for auto-discovery, bulk config, real-time monitoring, and remote maintenance.

RapidFire Series: Ultra-Long-Distance Wireless Backbone

Product Overview

The YNWPTP RapidFire 6-N and 6-25 are YNW flagship wireless bridges, built for ultra-long-haul PTP and PTMP backbone links (1-300km). They operate in the 6GHz band (5.900-6.400GHz) with a dedicated 1.2GHz CPU, hitting 700Mbps throughput and 200,000 PPS packet processing — carrier-grade specs for mission-critical backhaul.

Hardware Deep Dive

• 1.2GHz dedicated CPU: Purpose-built for high PPS throughput. Keeps forwarding efficiency high even at 100km+ link distances.
• Dual Gigabit Ethernet ports: Two 10/100/1000 Base-T ports, one with PoE pass-through (802.3af, 12.95W max). Supports 1+1 failover or daisy-chain relay for high-availability setups.
• IP67 cast-aluminum housing: GORE© membrane vent balances internal pressure and prevents condensation — critical for long-term seal integrity.
• IEC Level 4 surge protection: Built-in surge and ESD protection circuits meet power and rail industry safety standards.
• Removable handle & 45° antenna tilt: Makes transport and installation easier in rough terrain or tight tower spaces.

6-N vs 6-25: Core Differences

The 6-N’s external antenna design gives it the edge at 100km+ and for specialized beamwidth requirements. The 6-25’s integrated design eliminates cable loss and reduces installation complexity — ideal for the 30-50km sweet spot.

W-Jet V Proprietary Protocol

W-Jet V is what makes RapidFire tick. It’s a TDMA-based protocol purpose-built for high-performance PTP links:

• Rock-solid in noisy environments: Smart scheduling and error correction keep links stable even in crowded 6GHz spectrum.
• Ultra-low latency: End-to-end latency stays at 2-4ms — good enough for real-time video, voice, and industrial control.
• High PPS forwarding: Paired with the 1.2GHz CPU, maintains throughput across both large and small packet sizes.
• Adaptive modulation: Dynamically shifts from 256-QAM down to BPSK based on signal quality, maximizing link availability.

Typical Use Cases

• Cross-sea/river links: 50-150km submarine fiber backup or alternative
• Remote site interconnect: Mines, forests, reserves where fiber can’t reach
• Carrier backhaul extension: Last-mile fiber extension or temporary links
• Emergency communications: Rapid link restoration after earthquakes, floods
• Oil/gas pipeline monitoring: Hundreds of kilometers of data collection and video backhaul

YNW 6ac Series: Mid-Range PtMP Optimized

Product Lineup

Three models, same core platform (750MHz QCA 9563 + QCA 9882 radio, 64MB RAM, 16MB flash), all hitting 500Mbps throughput:

• YNW 6-15ac: Entry-level PtMP client/AP, PTP 7km / PTMP 5km
• YNW 6-20ac: Mid-range PtMP client/AP, PTP 15km / PTMP 10km
• YNW 6-90ac: Base-station-grade PtMP sector AP, PTMP 5km, 90° sector coverage

Three-Model Deep Comparison

The 6-15ac is compact (185g), ideal for space-constrained client installs. The 6-20ac’s 20dBi gain and 16° narrow beam deliver longer range and better interference rejection — good for core PtMP AP or long-range client duty. The 6-90ac’s 90° sector antenna covers wide areas, making it the natural base station choice.

iPoll 3 Proprietary Protocol

iPoll 3 is YNW’s secret weapon. Unlike standard 802.11 CSMA/CA, iPoll 3 uses active polling:

How it works:

1. Base station polls each connected CPE in sequence
2. BS sends data frames + a transmission token to the target CPE
3. CPE receives the token and transmits data back in its assigned time slot
4. BS acknowledges receipt, then polls the next CPE

Smart scheduling: iPoll 3 tags low-traffic CPEs as idle or low-activity and polls them less frequently. High-traffic devices stay on the active list and get more airtime. Benefits:

• Lower latency: No CSMA/CA collision detection or backoff waits
• Fewer data collisions: Token-based authorization eliminates simultaneous transmissions
• More concurrent connections: Single BS handles dozens of CPEs stably
• Stable throughput: Predictable scheduling gives each CPE guaranteed bandwidth

Smart QoS

YNW 6ac series supports hardware-accelerated QoS with four priority tiers:

• Four-tier classification: Network management > Voice > Video > Best-effort data
• L2/L3 marking: Based on L2 CoS and L3 ToS/DSCP
• WRR (Weighted Round Robin): Ensures proportional bandwidth allocation with no drops

This makes the YNW 6ac series a solid fit for mixed-traffic scenarios — surveillance, voice, data collection — where critical services need guaranteed quality.

YNW 5ax (WiFi6) Series: Gigabit Industrial Wireless

Why WiFi 6 Matters for Industrial

WiFi 6 (802.11ax) is a genuine leap over WiFi 5 (802.11ac) for industrial use:

• OFDMA: Divides channels into smaller Resource Units (RUs) for parallel transmissions to multiple devices — cuts multi-user latency and collisions.
• 1024-QAM: Each symbol carries more data than 802.11ac’s 256-QAM. ~25% throughput boost at short range.
• MU-MIMO (UL/DL): WiFi 6 supports both uplink and downlink MU-MIMO. WiFi 5 only did downlink. Big difference for bidirectional traffic.
• TWT (Target Wake Time): Devices negotiate sleep/wake cycles — significant power savings for battery-powered IoT.
• BSS Coloring: Co-channel interference identification. Reduces adjacent-BSS interference in dense deployments.

YNW 5ax brings all of this into the industrial wireless bridge form factor, delivering 1.5Gbps PHY throughput and much better interference handling.

Product Model Lineup

Key Technical Features

iPoll 3 evolution: YNW 5ax keeps the iPoll 3 polling protocol, now enhanced for WiFi 6’s OFDMA. Active polling + OFDMA subchannel allocation delivers better spectral efficiency and lower multi-user latency than vanilla 802.11ax.

Dual-band concurrent: Select YNW 5ax models support 2.4GHz + 5GHz concurrent operation — one band for management, the other for data.

Enhanced PoE: Supports both 802.3af/at active PoE and 24V passive PoE. Works with standard PoE switches, simplifies field wiring.

Full IPv6 stack: All models support IPv4/IPv6 dual-stack for future-proof network architecture.

Generational Leap Over 802.11ac

YNW 5ax series represents YNW latest in industrial wireless. For scenarios needing gigabit backhaul, high-density access, and future-proofing (think large surveillance clusters, industrial park core interconnect), the 5ax is the most forward-looking pick today.

YNW 6G ax Series: 6GHz WiFi6 Clean Spectrum

Product Overview

YNW 6G ax is YNW 802.11ax (WiFi 6) product line for the 6GHz band. It’s built on a Qualcomm 802.11ax dual-core SoC, with 2×2 MIMO, 160MHz channel bonding, and OFDMA. Aggregate throughput exceeds 1500 Mbps.

The 6GHz band (5.900-7.125GHz) is significantly cleaner than the crowded 5GHz band — fewer existing WiFi devices, no radar signals, and no DFS channel-switching headaches. For mission-critical links that need deterministic performance, this matters. YNW 6G ax combines this spectral advantage with WiFi 6 technology for a genuinely higher-quality wireless connection.

Product Model Lineup

Core Technical Features

6GHz clean spectrum: The 6GHz band (5.9-7.125GHz) has far fewer existing WiFi devices and radar signals than the 5GHz band. No DFS means no forced channel switches mid-operation. Links are more stable and predictable.

802.11ax 160MHz: WiFi 6 with 160MHz channel bonding delivers aggregate throughput over 1500 Mbps. On 6GHz, finding contiguous 160MHz spectrum is much easier than on 5GHz. OFDMA assigns subcarriers to different clients, boosting multi-user efficiency.

2.5G uplink port: All models ship with a 2.5 Gbps uplink port so the 1500+ Mbps wireless throughput isn’t bottlenecked by the wired side. The second port supports PoE OUT (802.3af/at) to power an IPC or other device directly — simplifies tower cabling.

2.4GHz independent management channel: Built-in 2.4GHz management radio lets technicians configure the device from up to 20m away using a phone or tablet. No need to run extra cables for tower-side config.

IP67 + surge protection: Corrosion-resistant metal housing, IP67 rated, -40℃ to +65℃ wide temperature range. Built-in surge protection meets IEC 61000-4-5 standard.

Four-Model Selection Comparison

Typical Use Cases

• High-reliability PTP backbone: In congested urban spectrum environments, 6GHz provides a cleaner transmission path. Typical use: HQ-to-data-center gigabit wireless backbone requiring 99.99% uptime and deterministic latency.
• 6GHz video surveillance backhaul: Large-bandwidth, low-interference wireless backhaul for HD video. 160MHz channel can carry multiple 4K video streams simultaneously without 5GHz WiFi interference.
• 6GHz PTMP base station coverage: The 6-90ax’s 90° sector antenna with 6GHz’s low-interference characteristics handles 10-15 clients per sector. Four 6-90ax units deliver full 360° coverage.
• Flexible networking with external antennas: The 6ax’s N-type interface pairs with high-gain parabolic antennas for 30km+ links — useful for cross-mountain and cross-lake terrain.

YNWPTMP Ecosystem: YNWBASE + YNWSU

System Architecture

YNWPTMP is YNW complete PtMP solution, made up of base station (BASE) and subscriber (SU) units:

• YNWBASE: Uses 6-90ac or 5-90ax sector antenna devices at the central site. Combine 90° to 360° multi-sector setups for full coverage. Single base station manages 50+ clients.
• YNWSU: Uses 6-15ac, 6-20ac, 5-20ax directional antenna devices at remote sites, connecting to the base station via PtMP.
• Infinity controller: Unified management platform for device discovery, bulk config, firmware upgrades, real-time monitoring, and alert management.

Sectorized Deployment

Typical YNWPTMP deployment centers on a core site with multiple YNWBASE sector units for 360° coverage:

• 4× 90° sectors: Four 6-90ac or 5-90ax units covering north/south/east/west for full coverage.
• 3× 120° sectors: Three units each covering 120°, useful when sectors need slight overlap.
• Mixed sectors: Flexible sector angles based on actual user distribution.

Each sector uses an independent channel/band. Adjacent sectors avoid co-channel interference through frequency planning. Combined with YNWSU’s directional antennas, this delivers efficient spectrum reuse and spatial isolation.

System-Level Advantages

• Unified NMS: Infinity controller provides topology visualization, performance reports, and fault alerts — slashes operational overhead.
• Plug-and-play: YNWSU supports auto-discovery and zero-touch provisioning. Remote site powers on and connects automatically.
• Remote firmware upgrade: Bulk remote firmware updates without tower climbs.
• Smart load balancing: Base station monitors signal quality and traffic load per client, dynamically adjusting connection strategy.
• Security: WPA2/WPA3 enterprise-grade encryption for over-the-air data protection.

Band Selection Strategy: 6GHz vs 5GHz

Band Characteristics Comparison

Band Selection Guidance

Go with 6GHz when:

• Link distance exceeds 15km for PTP backbone
• You need 80/160MHz wide channels for high throughput
• The 5GHz band is congested in your deployment area
• It’s a carrier-grade core link with high availability requirements

Go with 5GHz when:

• Client devices (CPE/SU) need broad base station compatibility
• Mid-range (5-15km) PtMP access scenarios
• Upgrading existing 5GHz infrastructure
• Budget-sensitive projects needing lower equipment cost

9. Key Selection Criteria & Decision Framework

9.1 Six Key Selection Metrics

1. Transmission distance: Measure the actual link distance (with Fresnel Zone margin). This is the primary constraint. RapidFire series (30-300km) > YNW 5ax (2-30km) > YNW 6G ax (2-15km) ≈ YNW 6ac (5-15km).
2. Band selection: Choose based on spectrum environment, distance, and local regulations. 6GHz (YNW 6G ax / RapidFire) excels in congested environments; 5GHz (YNW 5ax / 6ac) offers broader compatibility.
3. Throughput requirement: Estimate peak bandwidth. ≤500Mbps → YNW 6ac. 500Mbps-1.5Gbps → YNW 5ax or YNW 6G ax (6GHz preferred). ≥700Mbps over ultra-long distance → RapidFire.
4. Antenna configuration: Integrated antennas (6-25 / 6-20ac / 5-23ax / 6-20ax / 6-23ax, etc.) suit standard ranges. External antennas (6-N / 5-ax / 6ax) suit ultra-long distances or special beam requirements.
5. Protocol selection: PTP backbone → W-Jet V (RapidFire). PtMP access → iPoll 3 (YNW series).
6. Budget constraints: Pick the most cost-effective option that meets technical specs.

9.2 Decision Flow

10. Typical Deployment Scenarios & Product Recommendations

10.1 Scenario 1: Cross-sea / Cross-river Backbone (50-150km)

Recommended solution: RapidFire 6-N × 2 (one per end, with high-gain parabolic antennas)

Link budget: A 50km link requires ~140dB total gain budget. RapidFire 6-N with 30dBi parabolic antennas provides ~150dB system gain, leaving 10dB margin for adverse weather.

Key considerations: Fresnel Zone calculation, sea-surface multipath, tower height design, salt-spray corrosion protection.

10.2 Scenario 2: Oil & Gas Pipeline Monitoring (100-300km corridor)

Recommended solution: RapidFire 6-25 (30-50km segments) + YNW 6ac / YNW 5ax series for edge access

Network architecture: Relay sites every 30-50km along the pipeline, RapidFire 6-25 forms the linear backbone. Data collection points near each site connect via YNW 6ac (500Mbps) or YNW 5ax (1.5Gbps).

Key considerations: Power solution (solar + battery backup), extreme temperatures (-40°C to +65°C), surge protection, remote management.

10.3 Scenario 3: Mining / Quarry Communications (5-30km)

Network architecture: Deploy 4× YNWBASE sectors at the center site for 360° coverage. Each sector serves 20-50 YNWSU clients. In congested 5GHz areas, YNW 6-90ax sector base stations leverage clean 6GHz spectrum for more stable access.

Key considerations: Sector frequency planning, per-user bandwidth limiting, iPoll 3 multi-user performance, Infinity controller centralized management.

11. Deployment Best Practices

11.1 Link Planning

• Fresnel Zone calculation: Ensure 60%+ of the first Fresnel Zone is clear of obstructions. For a 6GHz 50km link, the Fresnel Zone radius is ~25m — tower height must account for this.
• Link budget calculation: System gain = TX power + TX antenna gain + RX antenna gain – cable loss – path loss. Reserve 10-20dB fade margin.
• Line-of-sight verification: Use Google Earth or professional tools (PathLoss, Radio Mobile) for profile analysis to confirm no obstructions between endpoints.

11.2 Installation

• Antenna alignment: RapidFire 6-25 (8° beamwidth) requires precise alignment. Use real-time RSSI indicators. Start with coarse alignment, then fine-tune using spectrum analyzer or built-in tools.
• Grounding & surge protection: All outdoor equipment must be reliably grounded (ground resistance ≤4Ω). Install surge protectors at Ethernet cable entry points. PoE injectors also need grounding.
• Weatherproofing: Apply waterproof tape + self-amalgamating tape on all exposed RJ45 connectors to prevent moisture ingress and corrosion.
• Cable management: Use outdoor-rated shielded cable (CAT5e or CAT6 minimum). Avoid running parallel to power lines — maintain 30cm minimum separation.

11.3 Network Optimization

• Channel planning: In PtMP deployments, use orthogonal channels for adjacent sectors (e.g., 5GHz channels 36/40/44/48). For 6GHz devices, prefer 80MHz channel width to balance throughput and interference.
• Power control: Minimize transmit power while maintaining link quality to reduce interference. YNW series supports per-channel ATPC (Automatic Transmit Power Control).
• QoS configuration: Set QoS policies per scenario — prioritize video streams for surveillance, per-user rate limiting for WISP, etc.
• Firmware upgrades: Keep devices on the latest firmware. YNW regularly releases performance optimization and security patches.

11.4 Operations & Maintenance

• Infinity controller: Deploy Infinity for centralized monitoring, configuration, and alerting across the entire network.
• Performance baseline: Establish a baseline (signal strength, throughput, latency, packet loss) during initial deployment. Run periodic comparisons.
• Log auditing: Enable system logs and alert notifications. Push real-time alerts to operations staff for abnormal events.
• Regular inspection: Conduct quarterly link quality checks and spectrum scans to catch potential issues early.

12. Summary & Outlook

This guide has walked through YNW complete industrial wireless bridge portfolio. From ultra-long-range backbone (RapidFire) to mid-range PtMP access (YNW 6ac) to gigabit WiFi 6 (YNW 5ax) and clean-spectrum 6GHz (YNW 6G ax), the product line covers 65%+ of industrial wireless communication scenarios.

Core selection principle recap: Distance determines band and series. Bandwidth determines the specific model. Environment determines protection grade. Accurate requirement analysis and scientific link planning are prerequisites for successful deployment. For ultra-long distance (>15km), lead with RapidFire 6GHz solutions. For mid-range (5-15km), choose flexibly between YNW 6ac (500Mbps) and YNW 5ax (1.5Gbps). For short range (<5km), entry-level YNW 6ac or YNW 5ax models handle client access.
