Wi-Fi Access Point Product

Overview

A wireless access point is the radio that turns a wired network into Wi-Fi coverage. Unlike a home router it does not route or hand out addresses; it bridges the air to an Ethernet backbone and is deployed in numbers across a building, each unit a cell that clients roam between. This is a ceiling-mount enterprise model, sealed in an unobtrusive puck that takes a single cable for both data and power.

That cable lands on the PoE Uplink Port, which splits off the network traffic and taps the DC supply to run the whole unit. Inside, the Radio Mainboard holds the Wi-Fi SoC, memory, and firmware flash that form the access point's brain. The SoC's two radios drive a pair of RF Front-End Module modules, one per band, that amplify transmit and receive signals before they reach the Antenna Array. The radio-transparent Radome Enclosure lets those antennas radiate through it, while the Mount Bracket twist-locks the unit to a ceiling grid.

How it works

The SoC runs two independent radios, one on 2.4 GHz and one on 5 GHz, so a client picks whichever band serves it best. Each radio's baseband produces a low-level signal that is far too weak to fill a room, so it passes through a front-end module. On transmit a power amplifier raises it to the regulatory limit; on receive a low-noise amplifier lifts faint client signals before the SoC tries to decode them. A fast switch shares each antenna between the two directions, and a SAW filter keeps each chain inside its band.

Multiple antennas per band are what make the access point fast. With Wi-Fi 6 the radio runs MU-MIMO, sending several spatial streams at once and even serving several clients in the same airtime, steering energy toward each by adjusting the phase across antennas. The whole exchange is scheduled tightly so dozens of devices share the channel without colliding, and because the unit draws its power over the same Ethernet run, one cable to the ceiling is all an installer needs.
