MM-U0 Wi‑Fi HaLow USB Network Adapters

Introduction

Morse Micro’s MM-U0 series brings Wi‑Fi HaLow connectivity to Microsoft Windows PCs and laptops through a USB network adapter. Based on the IEEE 802.11ah standard, the adapters operate in the sub-GHz spectrum and are intended to connect a computer as a client on an existing Wi‑Fi HaLow network.

The series is offered in USB-A and USB-C versions, providing a direct way to add Wi‑Fi HaLow support to compatible Windows hosts without requiring an internal radio module.

What it does

The MM-U0 adapters function as station-mode Wi‑Fi HaLow clients. Connected through a USB 2.0 host interface, they allow a Windows computer or laptop to join a Wi‑Fi HaLow access point or router.

Each adapter uses the Morse Micro MM8108 Wi‑Fi HaLow chipset and is based on the MM8108-RD09 reference design. The radio operates in the sub-GHz spectrum, supports transmit power up to 26 dBm, and uses an SMA connector for an external Wi‑Fi HaLow antenna.

Microsoft Windows is supported, with native Windows driver support specified for Windows 11 devices.

Applications

• Connecting a Windows laptop to an existing Wi‑Fi HaLow access point or router
• Adding sub-GHz Wi‑Fi HaLow client connectivity to a desktop PC with a USB port
• Evaluating Wi‑Fi HaLow networks using a Windows-based host
• Integrating a PC or laptop into a long-range, low-power wireless network where Wi‑Fi HaLow is deployed

Design considerations

The MM-U0 is a station client rather than an access point or router, so it requires an existing Wi‑Fi HaLow access point or router for network connection.

Host integration depends on a USB 2.0 interface and the appropriate physical connector choice: USB-A or USB-C. The external antenna connects through SMA, which gives system integrators flexibility in antenna selection and placement but also means an appropriate Wi‑Fi HaLow antenna is part of the installation.

Windows support should be considered during deployment, particularly where native driver support on Windows 11 is relevant.
