802.11ac WiFi kit for fitlet2 - 802.11mc RTT support

In this review the 802.11ac WiFi kit for fitlet2 is examined for small-form-factor PC builders who need a ready-made wireless upgrade. The bottom line: this kit is for users who want reliable dual-band connectivity and the benefit of 802.11mc FTM Wi-Fi RTT support in a compact, self-assembled package. It is not a standalone product but a practical accessory that supplies an M.2 adapter, antenna hardware and a side panel so the fitlet2 can gain better WiFi range and advanced location timing features.

Key Features

• Intel 8260 AC M.2 adapter: provides dual-band 802.11ac performance and broad driver support for modern operating systems, improving throughput over older modules.
• 802.11mc FTM Wi-Fi RTT support: allows compatible devices and networks to use round-trip timing for more accurate indoor positioning and location-aware applications.
• Two external antennas: include both 2.4 GHz and 5 GHz antennas to improve reception and transmission across common WiFi bands for more stable connections.
• RP-SMA to MHF cables: two adapter cables let users connect the M.2 card to the external antennas without soldering, simplifying installation and placement.
• Side panel and instructions: the included side panel and printed instructions are intended for self-assembly, making the kit easy to integrate into the fitlet2 chassis without extra parts.

Who It's For

The kit is best for fitlet2 owners, integrators and hobbyists who want to add a modern Intel AC adapter and external antennas for improved wireless range and advanced features like Wi-Fi RTT. It suits users comfortable with basic self-assembly and opening a compact mini PC to install an M.2 card and route antenna cables.

It is less suitable for users who prefer plug-and-play external USB adapters or who do not want to open their system; anyone who needs a preinstalled solution or professional installation should look elsewhere.

Pros & Cons
