RFM offers a full set of custom embedded wireless networking solutions like Zigbee wireless mesh sensor networks, RF modules, IC transceiver, IC transmitters and IC receivers. RFM, Inc. manufactures low power wireless and RF radio modules, wireless mesh nodes for distributed sensing on distributed sensor networks. Low Power radio, n../arrowband and short range devices, front end saw filters, active RFID, RFIC, coupled resonator filters, single silicon chips in the 70MHZ and 300-1000Mhz range.
Certified modules save original equipment manufacturers (OEMs) time and money!
All RFM OEM certified modules come with FCC, IC and ETSI module certification, so no FCC/ETSI-type acceptance testing required.
Each RFM transceiver module is treated just like other integrated circuits, with reflow soldering or connector pins for optional use.
Small size, there is no size penalty associated with the convenience of a module.

Interface
Frequency: If the product application will be offered in many countries 2.4 GHz modules provide a single solution for all markets. If the product will be marketed in:
N. or S. America choose 900 MHz or 2.4 GHz
Europe or China choose 434 MHz or 2.4 GHz
Japan or Korea choose 2.4 GHz
Australia or New Zealand choose 434 MHz, 900 MHz, or 2.4 GHz
Data Rate: Does the application require low, medium, or high data through-put?
Range: Over what indoor or outdoor distance is data to be transmitted?
RF Power: Is long battery life or transmission distance the primary importance? The lower the RF power - the longer the battery life. The longer the transmission range – the higher the RF power required to transmit over extended ranges. Also, is the application to be powered by AC mains or by battery? If battery-powered, then obtaining the lowest RF power is important.
Standards: If standards-compatible products or standardsbased wireless communications is important for the product application then choose ZigBee, 802.15.4, or 802.11b/g. If lowest power is most important choose mesh. If highest resistance to interference is most important then choose FHSS mesh or proprietary FHSS.
Network Topology: If the application requires a decentralized network topology where if a node fails it will dynamically find and re-route the data (like the Internet), then choose mesh. Further, if in a mesh network topology the application requires devices to be mobile, then choose RFM proprietary mesh. Choose point-to-point or point-to-multi-point network topology if a centralized network topology bearing very low attendant overhead costs is most important.
Technology: The product application primarily operates where:
long-range and/or high data-rate transmission within adverse conditions (e.g., industrial), FHSS provides secure and highly reliable RF transmission that is resistant to interference
high data-rate transmission, particularly for Ethernet LAN, 802.11b/g provides wireless communications for data rates of 11 Mb/s
a balance between data rate and power consumption is important, 802.15.4 and ZigBee technology provide rapid synchronization, moderate interference robustness and a good data rate-to-power consumption ratio
low power consumption is required to support battery operation in sensor networks or low traffic serial communications, the proprietary mesh modules are the best choice
Sensors / Serial Connections or UART / I/O Interface: Does the application need direct connection to sensors, or serial devices, or both?
