Ready-Made OEM RF Modules and Standalone RF Devices
Wireless Sensor Networking for Low-Power, Low Data-Rate Through-Put
RFM wireless sensor networking (WSN) products include ready-made transceiver modules and standalone
(boxed) products that enable OEMs to provide low-cost wireless control and monitoring functionality in low-data
rate, low-power applications that require long battery life, such as home automation, energy, telecommunication
applications, and personal home and hospital care.
Standard or proprietary ? RFM offers wireless sensor networking products based on two open standards ZigBee
and IEEE 802.15.4 for OEMs designing very low-cost condition monitoring and control applications. RFM
proprietary products are optimized specifically for low-power consumption applications and gain robustness with
Home Entertainment and Control -- smart lighting,
advanced temperature control, safety & security and
movies & music
Home Awareness -- water sensors, power sensors,
smart appliances and access sensors
mesh network technology.
RFM wireless sensor networking products operate in the following industrial, scientific and medical (ISM) radio
bands: 434 MHz (accepted in Europe and China), 900 MHz (accepted in USA, Canada, Australia, or New
Zealand), or 2.4 GHz (accepted in most jurisdictions worldwide.)
Commercial Building Automation –- building
commissioning, energy monitoring, HVAC, lighting,
server room, access control, device control,
condition-based maintenance

2.4 GHz ZigBee ZMN-series: new single-chip ZigBee transceiver modules based on the ZigBee 2006 and
come with FCC module certification. The low power-usage allows longer life with smaller batteries. The self-
healing mesh networking provides high reliability and longer range. Standalone products include ZigBee
Ethernet and ModBus Gateways that can function as a ZigBee network coordinator or take-out point.
2.4 GHz 802.15.4 LPR-series: transceiver modules based on IEEE 802.15.4 standard and come with FCC
module certification. For applications that need cost and power savings but do not require mesh networking
and its attendant overhead. Provides excellent peer-to-peer and star topology wireless networking.
Standalone products include 802.15.4 serial modems that serve as wireless replacement for RS-232 cables.
434 MHz / 916 MHz Proprietary Mesh DM18-series and DM22-series: transceiver modules based on RFM
proprietary technologies and platforms. For applications that need cost and power savings, reliable self-
healing mesh networking and a simple wireless sensor network protocols.
Security / Public Safety –- air quality monitoring,
first-responder systems, border / perimeter security,
hazards materials management, water security
systems, wastewater management, personal safety
devices, security & alarm systems
Industrial Plant –- SCADA, process control and
automation instrument calibration, asset
management, environmental management, energy
management, device control
Energy / Utilities -- automated meter reading,
substation integration, distribution automation, utility
sub-metering, oil/gas production monitoring
Supply Chain Management -- inventory monitoring,
container tracking, cold-chain monitoring
Proprietary FHSS for Long-Range, High Data-Rate Through-Put
900 MHz and 2.4 GHz Proprietary FHSS Ready-Made RF Modules WIT-series. RFM proprietary FHSS
products provide robust wireless industrial telemetry for industrial and factory environments that require radio
transmission that is far more resistant to electrical noise and interference, jamming and multi-path fading than
conventional radio transmission. Frequency Hopping Spread Spectrum (FHSS), originally developed for the
military, is widely utilized for industrial and manufacturing device applications because it employs a technique to
spread a signal over multiple frequencies to ensure reliable over-the-air transmission in under adverse conditions.
For industrial and SCADA (supervisory control and data acquisition industrial automation systems), FHSS provides
greater transmission range than is afforded by such protocols as 802.11. FHSS networking is useful in outdoor
applications where nodes may be separated by several miles, while ensuring fast, error-free delivery of data of up
to 20 miles.
900 MHz and 2.4 GHz Proprietary FHSS Standalone RF Devices HN-, HNIO-, SNAP-, and SEM-series. RFM
proprietary FHSS standalone RF devices can be paired with RFM proprietary FHSS modules or used alone for
fixed wireless network applications for a wide range of indoor, outdoor, and harsh environments.
WLAN Wi-Fi (802.11b/g) and WPAN Bluetooth (802.15) for Very High Data-Rate Through-Put
2.4 GHz, Very High Data Rate WLAN 802.11b/g Ready-Made RF Modules Airborne-series. RFM enhances
and offers Airborne 802.11b/g ready-made RF modules that, when embedded into product applications, enable
device access to local area networks (LAN). These ready-made RF modules provide very high data rates of up to
54 Mbps and transmit distances of up to 1,000 meters. They serve as replacement for serial cables in a broad
range of home, consumer, business and public wireless local area network (WLAN) applications.
2.4 GHz, 3 Mbps data rate Bluetooth Ready-Made RF Modules BlueGiga-series. RFM enhances and offers
BlueGiga Bluetooth ready-made RF modules that enable connectivity and information exchange between wireless
personal area network (WPAN) devices over shorter distances of up to 100 meters. These products are embedded
into such devices as mobile phones, laptops, personal computers, printers, GPS receivers, digital cameras, and
video-game consoles. Also, they often serve as replacement for traditional wired serial communications in GPS
receivers, medical equipment, bar code scanners, and traffic control devices and are useful as controls where
infrared is traditionally used.
