Comnet NW1 Wireless Ethernet Bridge
The Comnet NW1 is a pole-mountable wireless bridge engineered for point-to-point and point-to-multipoint Ethernet connectivity across campus security networks, perimeter deployments, and remote sites where traditional cabling is impractical. Operating on the 802.11a/n standard, the NW1 delivers 95 Mbps throughput with a maximum transmission range of 500 meters—sufficient to bridge separated buildings or outdoor security zones without the labor and material cost of trenching fiber or copper runs. The device supports centralized management via SNMP 2c, Telnet, and Syslog, allowing integrators to monitor and reconfigure units from a NOC or management workstation rather than traveling to field locations.
Key Features
- 802.11a/n Wireless Standard: Operates across 5 GHz bands, which experience less RF congestion than 2.4 GHz—a real advantage in dense urban or multi-site deployments where numerous WiFi networks and surveillance systems compete for airtime. Reduces retransmission delays and packet loss compared to crowded lower-frequency channels.
- 95 Mbps Data Transfer Rate: Adequate for concurrent video streams, access control signaling, and intercom traffic over a single wireless link. For reference, a single H.264 1080p camera at 2–4 Mbps leaves substantial headroom for redundant or parallel streams on this bridge.
- 500-Meter Maximum Range: Eliminates the need for intermediate repeaters or meshing in most campus or perimeter scenarios. Exact range depends on antenna height, line-of-sight clarity, and environmental obstructions—plan field deployments with a margin below this maximum.
- Single Gigabit Ethernet Port: Standard RJ45 connection integrates directly with managed network switches, IP cameras, access control panels, and NVR systems. No proprietary connectors or vendor-lock cabling.
- 30W PoE Budget (IEEE 802.3af/at): Powers downstream devices such as wireless access points, IP cameras, or alarm communicators without separate field power runs. A critical cost and labor saving in remote installations where AC supply or dedicated DC lines are unavailable or expensive to deploy.
- SNMP 2c, Telnet, and Syslog Management: Configure and monitor the NW1 from a central management platform—critical for 24/7 security operations. Integrates with PRTG, Nagios, or vendor-specific NOC dashboards. Syslog output enables audit trails and troubleshooting without console access to each device.
- Pole-Mountable Form Factor: Compact design mounts directly to existing utility poles, fence posts, or structures. Reduces installation time and avoids the need for custom mounting brackets or additional support structures.
- Industrial Operating Temperature Range: Rated for extended outdoor cycles, ensuring reliability in climates from freezing to high heat without performance degradation.
Integration and Deployment Context
The NW1 bridges wired and wireless network segments, making it ideal for connecting remote IP cameras, access control readers, or intercom panels back to a central management facility. The single Gigabit Ethernet port accepts standard network patch cables and integrates with managed switches, network video recorders, and security control systems using standard IP protocols. SNMP 2c monitoring allows the NW1 to report link status, signal strength, and configuration state to centralized management platforms for proactive alerting if a remote site loses connectivity.
Organizations deploying multiple NW1 units across 5–50 sites benefit from batch provisioning via Telnet or SNMP-based configuration, avoiding repetitive on-site console access. When planning a PoE power budget across a multi-location network, the NW1's 30W output allows downstream device consolidation, reducing the number of separate power injectors or PSUs needed in the field.
The 802.11a/n standard operates in the 5 GHz band, which carries fewer consumer WiFi networks than 2.4 GHz. This translates to lower retransmission rates and more predictable latency for real-time video or access control traffic—especially important in urban or RF-dense campuses. However, 5 GHz signal strength drops faster over distance and through obstacles compared to 2.4 GHz; validate line-of-sight and antenna placement during site surveys before final deployment.
Frequently Asked Questions
Q: Does the NW1 require line-of-sight between the two endpoints?
A: Optimal performance requires direct line-of-sight or minimal obstruction between the transmit and receive antennas. Heavy foliage, dense building structures, or metal barriers reduce the effective range significantly below the 500-meter maximum. Conduct a site survey with a spectrum analyzer or demo unit before finalizing mounting heights and antenna orientation.
Q: Can I use the NW1 to extend a single PoE-powered camera across 300 meters of open ground?
A: Yes. Mount the NW1 near the camera with a short Ethernet patch cable, pair it with a wireless NW1 at the base station or switch, and the 30W PoE budget from the remote bridge can power a compatible 802.3af or 802.3at device. This eliminates the need to run power separately alongside a long copper run.
Q: What management tools does the NW1 support?
A: The NW1 supports SNMP 2c (read and configuration), Telnet (command-line configuration), and Syslog (event logging). It does not include a proprietary GUI or cloud dashboard. Integrate it into PRTG, Nagios, or similar open-standard NOC platforms for centralized monitoring.
Q: Is the NW1 suitable for high-bandwidth video streams (4K, multiple HD cameras)?
A: The 95 Mbps throughput can carry 2–3 concurrent H.264 1080p streams or a single lower-bitrate 4K stream, assuming wireless signal quality remains strong. For heavy multi-camera deployments, consider a point-to-point microwave or licensed RF bridge as an alternative, or deploy multiple NW1 pairs to segregate traffic.
Q: What is the warranty on the NW1?
A: Refer to the Comnet product documentation or your specialty reseller for warranty terms and coverage. Standard manufacturer warranties typically cover hardware defects for 12 months from shipment.

The Comnet NW1 has proven reliable for moderate-distance point-to-point campus security links. The 802.11a/n standard is the backbone of this design—operating in the less-congested 5 GHz band shields your video and access control traffic from the RF noise that plagues 2.4 GHz in urban and multi-tenant sites. The NW1's managed capabilities—SNMP 2c, Telnet, and Syslog—are non-negotiable for integrators running 24/7 security operations; passive wireless devices without remote diagnostics become liabilities the moment a link degrades or a configuration change is required in the field.
Technical Highlights:
- 95 Mbps Throughput: Sufficient for 2–3 concurrent H.264 1080p video streams plus access control signaling. For single or dual high-bitrate 4K sources, verify bandwidth calculations with actual codec profiles before deployment—overhead and retransmission can consume 10–20% of raw capacity in less-than-ideal RF conditions.
- 500-Meter Maximum Range: Outdoor range in open terrain with good antenna placement and line-of-sight. Every obstruction—trees, buildings, metal structures—reduces effective range. Budget 30–40% margin for real-world installation. In dense urban settings, effective working range may be 250–350 meters; field testing is mandatory before production rollout.
- 30W PoE Output: Powers downstream IEEE 802.3af/at devices, eliminating the need for separate power runs to remote camera or access point installations. This is a labor and material cost multiplier on large multi-site deployments.
Deployment Considerations:
- 5 GHz propagation is line-of-sight sensitive; even moderate foliage between endpoints causes signal dropout. Always include a site survey step with a spectrum analyzer or loaner unit before committing to NW1 as the primary link.
- The single Gigabit Ethernet port means you cannot segregate video and access control into separate wireless channels on a single NW1 unit. For QoS-critical deployments, plan for dual-bridge pairs or network-level prioritization on the wired side.
- SNMP 2c is cleartext and is not suitable for high-security networks without an out-of-band management VLAN. If your security posture requires encrypted management, evaluate whether a separate management bridge or IPsec tunnel is necessary.
The NW1 is the right choice for perimeter or campus deployments where wired cabling is impractical, RF interference is moderate, and you need remote observability without proprietary cloud infrastructure. For long-distance (>500m), RF-congested, or mission-critical links, consider licensed microwave or point-to-multipoint licensed spectrum bridges.
