This article covers Ubiquiti Networks NBE-5AC-GEN2 NanoBeam ac Gen2 airMAX ac CPE 専用管理ラジオ付き 2個パック.

Overview

The Ubiquiti Networks NanoBeam ac Gen2 (model NBE-5AC-GEN2) is an outdoor CPE (Customer Premises Equipment) operating in the 5 GHz band. It delivers real-world throughput of over 450 Mbps and can establish stable point-to-point (PtP) links exceeding 15 km. This 2-pack includes both the transmitter and receiver units, making it a convenient all-in-one solution for first-time long-range wireless builders. The integrated 19 dBi dual-linear polarization antenna focuses RF energy into a narrow beam, effectively rejecting noise from adjacent signals. A dedicated management Wi-Fi radio allows on-site configuration and alignment from a smartphone or tablet without needing a wired connection to the unit.

Connectivity & Compatibility

The NanoBeam ac Gen2 features a single 10/100/1000 Mbps Gigabit Ethernet port with PoE (Power over Ethernet) support. The included 24V 0.5A PoE injector delivers both power and data over a single Ethernet cable, simplifying outdoor installation. Wireless standards supported include IEEE 802.11ac with Ubiquiti's airMAX ac protocol, operating exclusively in the 5 GHz band. Channel widths are selectable from 10/20/30/40/50/60/80 MHz (limited to 10/20/30/40 MHz in PtMP mode). For best performance, pair this CPE with Ubiquiti airMAX ac access points such as the Rocket ac or PowerBeam ac series. The device runs airOS 8, which is a separate management ecosystem from UniFi, but both can coexist on the same network.

Product Info

The NanoBeam ac Gen2 is the second generation of Ubiquiti's airMAX ac CPE line, launched around 2019 and still actively sold. The 2-pack typically retails for around ¥50,000–¥55,000 in Japan, positioning it in the mid-to-high tier for outdoor wireless gear. While not cheap, the build quality, performance, and reliability justify the price for serious users. Warranty is the standard one year from the manufacturer. The package includes two NanoBeam units, ball-joint mounts, locking rings, metal straps, Gigabit PoE injectors (24V 0.5A), mounting brackets, and power cords.

Best Use Cases

Connecting two buildings on the same property: If you need to link your house to a detached garage, workshop, or guest house with near-wired speeds, the NanoBeam ac Gen2 is an excellent choice. It handles distances well beyond typical consumer mesh systems. Small ISP or community network deployments: For providing internet access in rural or mountainous areas where fiber is unavailable, this CPE offers a cost-effective and reliable last-mile solution. The management radio simplifies on-site alignment. * Temporary event or construction site networks: When running Ethernet cables is impractical, a pair of NanoBeams can establish a high-speed link in minutes, powered by PoE. This product is less suitable for users who simply want to extend indoor Wi-Fi coverage — a standard repeater or mesh system would be easier and cheaper. It also requires a moderate level of networking knowledge for proper configuration.

Things to Consider

The NanoBeam ac Gen2 is designed exclusively for outdoor use. While it has weather-resistant construction, it is not intended for indoor deployment. It operates only on the 5 GHz band, so it cannot directly connect to 2.4 GHz-only devices. Reliable long-range operation requires a clear line of sight between the two units. Trees, buildings, or other obstructions will significantly degrade performance or prevent link establishment altogether. Configuration through airOS 8 is intuitive but still demands familiarity with wireless parameters such as channel width, frequency selection, and transmit power. First-time users should consult Ubiquiti's official community forums or setup guides before installation. ## FAQ
Q: Can I use this product to get internet access directly? A: No. The NanoBeam ac Gen2 is a CPE (client device). You need a compatible Ubiquiti access point (e.g., Rocket ac) connected to an internet source on the other end. This device connects wirelessly to that access point. Q: What is the purpose of the 2-pack? A: The 2-pack is designed for point-to-point (PtP) links. Configure one unit as an access point and the other as a station to bridge two locations wirelessly. Q: How far does the management Wi-Fi radio reach? A: The management radio is intended for close-range setup (a few meters). After the link is established, you can manage the units via the wired Ethernet connection.
