FGH100MAAMD - Wi-Fi HaLow 802.11ah 850-950MHz Module | Quectel
MPN： FGH100MAAMD ✓ 啟用中FGH100MAAMD 概覽
Wi-Fi HaLow (IEEE 802.11ah) is an open Wi-Fi standard purpose-built for the sub-1 GHz spectrum. Unlike conventional 2.4 GHz/5 GHz Wi-Fi (802.11n/ac/ax), sub-1 GHz propagation penetrates walls and terrain far more effectively and enables link ranges measured in hundreds of meters to kilometers, while retaining native IP connectivity, WPA3-class security, and standard Wi-Fi tooling. In the wireless-IC hierarchy it sits between short-range Wi-Fi/BLE modules and cellular LPWAN modules (NB-IoT, LTE-M), trading bandwidth for range and battery life.
The module integrates the Morse Micro MM6108 Wi-Fi HaLow chipset and supports 1, 2, 4, and 8 MHz channel bandwidths, allowing designers to trade data rate for range and power consumption. Host interfacing is via SDIO 2.0 or SPI, so it drops into Linux or RTOS-based designs exactly like a conventional Wi-Fi module. The supply range is 3.0 V to 3.6 V, compatible with single-cell Li-ion and 3.3 V industrial rails.
Because Tx power is limited to comply with EU regulations, and no antenna is included, the FGH100MAAMD targets designs where the integrator provides an external antenna on a U.FL or castellated RF pad. Its long range makes it ideal for smart-city infrastructure, agricultural sensor networks, solar-powered gateways, video doorbells, and industrial telemetry across large campuses.
Design consideration: sub-1 GHz HaLow antennas are physically larger than 2.4 GHz antennas; verify antenna matching and RF layout against the Quectel hardware design guide, and budget supply current for transmit bursts when sizing batteries.

典型應用
FGH100MAAMD 適用於 6 應用s: Smart City Infrastructure, Agricultural IoT Sensor Networks, Industrial Telemetry and SCADA Extensions, Security Cameras and Video Doorbells, Solar-Powered Remote Gateways, Smart Metering and UtilityAMI.
Smart City Infrastructure
The FGH100MAAMD's sub-1 GHz IEEE 802.11ah link at 850-950 MHz delivers hundreds of meters to kilometers of range with wall penetration far superior to 2.4 GHz Wi-Fi, making it ideal for connecting streetlights, parking sensors, and environmental monitors across a city block from a single HaLow access point. The 13 dBm EU-compliant transmit power keeps deployments within regional regulations without site licensing. Using 1 or 2 MHz channel modes maximizes link budget for far nodes, while 8 MHz serves backhaul-hungry gateways. Because HaLow retains native IP and standard Wi-Fi security, city IT teams integrate it with existing management tooling rather than proprietary LPWAN stacks. The SDIO 2.0 host interface suits Linux-based smart-city controllers and edge gateways.

Agricultural IoT Sensor Networks
Farms need connectivity across open terrain where the FGH100MAAMD's sub-1 GHz propagation excels, reaching soil-moisture probes, weather stations, and irrigation valves hundreds of meters to kilometers away without cellular subscription costs. The module's low-power HaLow operation and 3.0-3.6 V supply accommodate small solar panels and Li-ion batteries on nodes that report a few times per hour. Narrow 1 MHz channels maximize range and minimize energy per transmission, directly extending battery life compared with 2.4 GHz Wi-Fi. The SPI interface attaches to low-cost MCUs in sensor nodes, while SDIO fits Linux gateways at the farm office. Per Quectel, this long-range, low-power profile is the primary design intent of the FGH100M series.
推薦
Industrial Telemetry and SCADA Extensions
In factories and utility substations, the FGH100MAAMD extends telemetry to tank farms, pump stations, and perimeter sensors where running Ethernet is costly and 2.4 GHz Wi-Fi cannot penetrate metal racking and concrete. Operating at 850-950 MHz with up to 13 dBm (EU-limited) and -30 C to +85 C temperature tolerance, it withstands unconditioned industrial enclosures. The SDIO 2.0 interface integrates with industrial Linux gateways and protocol converters, keeping Modbus or OPC UA data on standard IP networks end-to-end. Narrower channels trade throughput for penetration in dense facilities. Because it is RoHS compliant and surface-mount (13 x 13 x 2.2 mm), it fits standard SMT assembly flows for industrial controllers.
推薦
Security Cameras and Video Doorbells
Wi-Fi HaLow's combination of kilometer-class range and megabit-class throughput lets the FGH100MAAMD carry compressed video from doorbells and perimeter cameras where 2.4 GHz Wi-Fi is blocked by exterior walls and distance. The 4 and 8 MHz channel modes provide enough bandwidth for H.264/H.265 streams at entry-level camera resolutions, while native IP eliminates proprietary bridge hardware. The Morse Micro MM6108-based architecture supports standard Wi-Fi security, addressing the privacy expectations of residential customers. The 3.0-3.6 V input works with doorbell transformer or battery power rails. Integrators mount the 13 x 13 x 2.2 mm module directly on the camera mainboard with an external sub-1 GHz antenna per the Quectel hardware design guide.
推薦
Solar-Powered Remote Gateways
Remote monitoring sites, from pipeline cathodic-protection stations to national-park weather nodes, benefit from the FGH100MAAMD's HaLow link connecting distributed sensors to a single solar-powered gateway that then uplinks via cellular. The module's low-power operation preserves the limited energy budget: 1 MHz channels minimize transmit time per payload, and sleep-oriented HaLow MAC behavior reduces duty-cycle drain versus always-on Wi-Fi. The 850-950 MHz band penetrates vegetation better than higher bands, maintaining links through canopy and terrain. Its SPI interface allows a small MCU to manage the radio, while the gateway's SDIO path handles higher aggregation throughput. Per Quectel's positioning, this long-range, low-power profile defines the FGH100M series' target market.
推薦
Smart Metering and UtilityAMI
Utilities deploying advanced metering infrastructure use the FGH100MAAMD's sub-1 GHz range to link water, gas, and electric meters to neighborhood data concentrators without per-meter cellular subscriptions. The module's 850-950 MHz operation penetrates meter boxes, basements, and below-grade vaults where 2.4 GHz fails, and the -30 C to +85 C rating survives outdoor and pit-mounted installations. Narrow 1 MHz channels allow dense meter populations with robust links, and standard Wi-Fi security frameworks simplify utility-grade certification of the data path. The SPI host interface suits the metering MCU, while concentrators use SDIO. RoHS-compliant SMD-40P construction fits high-volume meter assembly lines using standard reflow processes.

主要差異化特點
- One of the first commercially available Wi-Fi HaLow (802.11ah) modules (對比Conventional 2.4 GHz Wi-Fi modules (e.g., ESP32-class))
- Integrated Morse Micro MM6108 chipset with SDIO 2.0 and SPI host options (對比Discrete MM6108 chip-down designs)
- Trade-off: EU-limited 13 dBm transmit power (對比Higher-power sub-1 GHz proprietary LPWAN radios)
設計說明
The FGH100MAAMD ships without an antenna, so the 50-ohm RF path is entirely the integrator's responsibility. Keep the RF trace from the module's antenna pad as short as possible, use controlled impedance (50 ohm) microstrip or coplanar waveguide, and place the pi-matching network within 2-3 mm of the module pad so it can be tuned after board-level VNA measurement. Sub-1 GHz quarter-wave antennas are physically large (about 8 cm at 900 MHz); reserve enclosure volume accordingly. Follow the Quectel FGH100M hardware design guide for keep-out and grounding recommendations.
Supply the module from a clean 3.0-3.6 V rail (nominal 3.3 V). RF transmit bursts create current spikes that a small LDO alone may not handle; place at least 10 uF bulk capacitance plus 100 nF ceramic decoupling directly at the module supply pins. When powering from a single-cell Li-ion (3.0-4.2 V), use a low-quiescent-current buck or LDO rated for the module's peak transmit current to hold the rail above 3.0 V during bursts. Verify actual peak current figures in the official datasheet during power budgeting.
Tx power is limited to comply with EU regulations, so do not expect the full link budget of regionally unlicensed variants; validate range against your specific sub-band allocation in the target market. Also confirm that your chosen 850-950 MHz channels are license-exempt in each country of deployment - the 802.11ah band plan is regional. Finally, driver support centers on the Morse Micro MM6108 ecosystem; confirm Linux kernel driver availability for your host SoC before committing to the SDIO interface.
