Ubiquiti airMAX ac Components: High-speed directional radio for outdoor networks - The Expert Guide

The airMAX ac product line from Ubiquiti Networks is the industry standard for building robust, scalable and fast wireless networks over long distances. As an evolution of the successful airMAX protocol (M series), airMAX ac uses the high-frequency 802.11ac standard in the 5 GHz band, optimized by Ubiquiti proprietary TDMA technology.

Unlike conventional WLAN, which struggles with collisions with many users, airMAX ac eliminates this problem through timed access (Time Division Multiple Access). The result: lower latency, higher stability and a real aggregated throughput of over 450 Mbit/s – ideal for connecting companies, networking campus areas or building a Wireless Internet Service Provider (WISP).

airMAX ac application areas: PtP vs. PtMP

The airMAX ac components can be primarily divided into two architectures, which are supported by dedicated product lines:

Point-to-Point (PtP) - The high-speed bridge

PtP connections create a dedicated, invisible cable connection between only two locations. This architecture is used to extend the network quickly and securely over distances of several kilometers. For PtP links, devices with high directivity are optimal, as they filter out interference signals and bundle all transmission energy onto a narrow target.

Point-to-Multipoint (PtMP) - The distributor star

PtMP networks consist of a central base station (Access Point) that communicates with several end devices (CPEs). This is the typical setup for a WISP delivering internet to rural areas. The base stations typically use Rocket AC radios in combination with sector antennas (e.g. 60°, 90°, 120°), while customers use CPEs such as the NanoStation AC or LiteBeam AC.

The airMAX ac product family at a glance

Each airMAX ac series is optimized for a specific role in the network and contributes to the overall performance of the radio link:

airOS 8 and the fight against interference

The airMAX ac components are managed via the powerful airOS 8 operating system. This system offers important tools for ensuring link quality:

1. AirView Spectrum Analyzer: Enables real-time analysis of the radio spectrum to identify interference sources and choose the best frequency channel.
2. AirFiber technologies: Many AC devices benefit from advanced technologies such as airPrism, which significantly improve noise reduction and co-existence (co-location) of multiple sector antennas on a mast.
3. 24V Passive PoE: Power is supplied via passive PoE as standard, which enables easy outdoor installation with only one cable (data and power).

Choosing the right component always depends on the required range, the desired throughput and, above all, the line of sight (LOS). Use Ubiquitis planning tools to ensure that you keep the 1st Fresnel zone clear for an interference-free connection. With airMAX ac, you are investing in a future-proof and professional network infrastructure.
