Key Features

Dual-Mode Fiber + Wireless Networking

Integrates 1× Gigabit SFP fiber port plus 1× Gigabit Ethernet port. SFP uplink connects to fiber backbone while wireless extends coverage — perfect for hybrid network topologies.

High-Speed 802.11ac Wave 2

2×2 MIMO delivers up to 867 Mbps PHY rate on 5 GHz. 80 MHz channel support enables high-throughput backhaul for 4K cameras, VoIP, and data-intensive applications.

27 dBm EIRP High Transmit Power

Delivers robust output power for long-range PTP links up to several kilometers. Three RP‑SMA connectors support flexible antenna configurations (2Tx/1Rx or 1Tx/2Rx).

Industrial IP65 + Wide Temperature

IP65 ingress protection shields against dust and water jets. Operates reliably from -40°C to +70°C, surviving harsh outdoor environments in tropical, desert, and alpine regions.

Flexible PoE Powering Options

Passive PoE input accepts 8–30 V DC (recommended 24 V). Built-in PoE output (24 V DC) powers downstream devices — simplifies cabling in deployed installations.

Advanced Wireless Protocols

Proprietary Nstreme and NV2 protocols optimize throughput and latency. CAPsMAN enables centralized management of multiple units. Virtual AP and WDS support complex network architectures.

Target Applications

5 GHz outdoor high-speed PTP/PTMP wireless bridging — 867 Mbps meets high-throughput backhaul requirements for multi-camera surveillance and enterprise connectivity
Fiber + wireless hybrid networking — SFP uplink to fiber backbone with wireless extension to expand coverage in hard-to-wire areas
Small/medium outdoor base stations — Multiple Virtual APs and CAPsMAN centralized management for scalable deployments
Industrial wireless networking — Wide temperature range (-40°C to +70°C) plus IP65 protection for hot, cold, or humid outdoor environments

Frequently Asked Questions

Q: What antenna types are compatible with this PCBA?

The board provides 3× RP‑SMA connectors. For PTP links, standard outdoor panel or dish antennas with RP‑SMA male connectors work well. For PTMP base stations, sector antennas (90°/120°) are recommended. All antennas should be rated for the 5.150–5.875 GHz frequency range.

Q: Can this unit be powered over the Ethernet cable?

Yes — the board supports Passive PoE input (8–30 V DC) on the Ethernet port. Use a Passive PoE injector with 24 V DC output for best results. The board also features PoE output (24 V DC) to power a downstream device such as an IP camera.

Q: What is the maximum transmission distance?

Actual range depends on antenna gain, operating frequency, and environmental conditions. With high-gain directional antennas (27 dBi dishes) and clear line-of-sight, links exceeding 10 km are achievable at lower data rates. For reliable long-range performance, always conduct a site survey.

Q: Is this PCBA compatible with MikroTik RouterOS?

This board is based on Atheros QCA9558 + QCA9886 chipsets, which are supported by RouterOS. However, compatibility depends on the specific firmware/build. Check with your firmware provider for RouterOS-compatible images and installation instructions.

Q: Does this support 802.11ax (WiFi 6)?

No — this unit supports 802.11a/n/ac (WiFi 5, Wave 2). For WiFi 6 / 802.11ax outdoor solutions, consider boards based on Qualcomm IPQ5018 or MediaTek MT7975 chipsets.

Q: What is the typical latency for wireless backhaul?

Using Nstreme or NV2 proprietary protocols, round-trip latency typically ranges from 1–3 ms under clear line-of-sight conditions at close range. Latency increases with distance, antenna type, and channel congestion. For latency-sensitive applications (VoIP, gaming), a site-specific evaluation is recommended.
