LoRa® (abbreviation for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. LoRa® Technology is a long range, low power wireless platform that has become the de facto technology for Internet of Things (IoT) networks worldwide.
LoRa® radio modules
The iM880B-L is a compact and low-cost radio module that operates in the unlicensed 868 MHz band and combines a powerful Cortex® M3 controller with the LoRa® transceiver of Semtech. A sensitivity of up to -138 dBm and a maximum output power of +19 dBm results in a link budget of more than 156 dB. Even when reducing the output power to +14 dBm ranges beyond 15 km are possible in free space.
The iM881A-XL is a compact and low-cost radio module that operates in the unlicensed 868 MHz band and combines a powerful Cortex® M0+ with the LoRa® transceiver of Semtech. It has been specifically designed for battery driven devices. It consumes less than 28 mA in transmit mode at +13 dBm. With an excellent sensitivity of -138 dBm a range beyond 12 km can be achieved (LoS).
The iM282A-L is a compact and low-cost radio module that operates in the unlicensed 2.4 GHz band and combines a powerful Cortex® M3 controller with the new ultra long range transceiver SX1280 of Semtech. It is able to achieve without any additional amplifiers a LoS range of more than 12 km.
The iM980B-L is a multiband radio module that operates in the unlicensed 868 and 915 MHz band and combines a powerful Cortex® M3 controller with the LoRa® transceiver of Semtech . A sensitivity of down to -138 dBm and a maximum output power of +18.4 dBm results in a link budget of more than 155 dB. The iM980B has received Federal Communications Commission (FCC) approval.
LoRa® concentrators
The concentrator module iC880A is a multichannel high performance transmitter/receiver module designed to receive several LoRa® packets simultaneously using different spreading factors on up to 8 channels in parallel. In combination with an embedded Linux board like Raspberry Pi, and the HAL software from Github a complete LoRaWAN® gateway can be setup easily.
The iC280A concentrator module enables high-performance LoRa® gateway solutions or retrofit existing routers with 2.4 GHz LoRa® gateway capabilities. In mini PCIe form factor based on Semtechs sx1280 chipset, this radio concentrator allows robust communication between a LoRa® gateway and a huge amount of LoRa® end-nodes spread over a wide range of distance.

LoRa® products
The Wireless M-Bus Range Extender is a compact and cost-effective device that collects wireless M-Bus messages from utility meters and forwards them to a LoRaWAN® network.
This device acts as a bridge between wireless M-Bus and LoRa® and allows a flexible configuration of calendar events for WM-Bus reception intervals and status messages as well as device filtering by Manufacturer ID and Device ID (whitelist). The configuration can be managed Over-The-Air via LoRa® messages (on request) or via wired serial interface.
The iOKE868 Smart Metering Kit monitors the utility usage measured by most modern meters fitted with optical interface (compliant to IEC62056-21) and determines the total consumption within a residential property. It is also indicated for all companies that want to manage their energy consumption and the feed-in from photovoltaic systems.
The optical unit iO881A can be attached magnetically to the smart meter to read out the infrared interface, extract the desired values and transfer those to the LoRaWAN® network with a periodicity defined by the user.
The iU880B is a compact and cost–effective USB stick based on the Long Range Radio Module iM880B-L.
The iU880B is qualified according to the RED 1999/5/EC. With an adjustable output power of up to +18 dBm (EIRP) combined with the outstanding sensitivity of the USB-Stick high ranges can be achieved. USB to UART Bridge Virtual COM Port (VCP) drivers for Microsoft Windows, WindowsCE and Linux are available here.
The iU880B is targeted for a huge variety of application like Smart Metering, Smart Cities, IoT- and M2M-applications.
The Lite Gateway 868 MHz is a demonstration and evaluation platform consisting of the pre-certified concentrator iC880A, a Raspberry Pi, a pre-configured SD-card and a aluminum housing. This device enables LoRa® customers to demonstrate and evaluate LoRaWAN® features, and can be easily connect to existing servers (e.g. Loriot or The Things Network ). The source code of firmware is provided by the open source Github project.
The Lite Gateway 2.4 GHz is a demonstration and evaluation platform consisting of the pre-certified concentrator iC280A, a Raspberry Pi, a pre-configured SD-card and an aluminum housing for the 2.4 GHz worldwide freq. band. This device enables LoRa® customers to demonstrate and evaluate LoRa® features, and can be easily connect to Loriot, The Things Network or A2A Server. The source code of firmware is provided by the open source Github project.

LoRa® development kits
The WiMOD Shield is a expansion board that enables users of Arduino® / Arduino-compatible boards to use iM880B-L radio module based on LoRa® technology.
Arduino® boards are microcontoller-based boards that allow the user to do simple designs and prototypes or experiment with microcontroller circuits in general. The boards offer an interface for extending the basic functionality like sensors and actors by just stacking the extension boards to the base board.
The WiMOD Shield is a small and low cost extension board that can be attached to the top offering an radio interface based on the LoRa® technology. The shield is an interface card for connecting a WiMOD radio module to an Arduino® board.
