05 / From possibility to a working connection
Actual starter kits, optical receivers, and a clear setup path. Keep your internet service and bring the last wireless meters into the optical domain.
LiFi is commercially offered today. A complete kit is a practical way to begin.

A matched optical access point and USB dongle, plus Ethernet cable and Gigabit PoE+ injector. The manufacturer lists a 100 Mb/s data rate and a typical 3 m coverage diameter at a 2.2 m link distance. [28]
Seller listing checked September 7, 2026: $1,499. Confirm destination, stock, shipping, and device support before ordering. [30]
Optical access infrastructure and compatible USB receivers for existing devices. The manufacturer documents the receiver’s optical-safety classification and automatic signal cut-off. [31]
Explore LiFiMAX systems ↗The 6002 family serves laptops and tablets through optical receivers. Supported controller configurations join coverage areas for seamless handover. [4]

Use Ethernet from your existing router or switch. With a PoE kit, the injector supplies power and data through the access-point cable.
Mount or position it as directed by the manufacturer. Put the intended working area inside the optical footprint.
Attach the compatible USB dongle to your laptop or tablet. Place its optical window where it can communicate with the access point. Follow any driver instructions for your device.
Open a video call, browse, and transfer a file. Once the optical connection is working, turn off the Wi-Fi link it replaces and configure any automatic radio fallback to match your goal.
You keep your internet service. You change the local access medium.
| Where | Useful choice | What it contributes |
|---|---|---|
| Building and network backbone | Fiber / wired infrastructure | Capacity and a defined physical path |
| Fixed workstation or screen | Ethernet | A simple, dependable connection |
| Device moving within a room | Infrared LiFi | Wireless access through an optical carrier |
| Several rooms or optical cells | Wired backhaul plus supported optical handover | Coverage scaled around the building |
Choose the receiver location as deliberately as you choose a lamp or a desk. Optical access works best when the intended path is available. Larger systems can use multiple cells to cover more positions.
For the RF-reduction objective, check both directions: optical download and optical upload. An Ethernet-fed access point avoids using a radio bridge as the backhaul. Device radio settings should remain as intended after restart or a lost optical connection.
LiFi adds a physical privacy boundary. Pair it with normal network authentication, encryption, and software maintenance; include doors and windows when deciding where the optical signal can travel.
Start with a representative learning space and the devices already in use. A useful pilot shows that students and teachers can do their work with the intended optical coverage.
Checkmarks stay in this open page; they are not submitted. Performance and RF measurements document the engineering result.
Every useful installation helps answer the questions that make the next one easier: which receivers work best, where coverage belongs, how people move, and what support they need.
You do not need to replace an entire building to learn something valuable. Start with a room where optical access solves a real problem. Keep the successful configuration, document what you learned, and expand when it serves your needs.
That is how an engineering option becomes an everyday choice.
