EMB-LR1121-e
868/915 MHz & 2.4 GHz LoRa® Multi-Protocol Module*
EMB-LR1121-e is the new LoRaWAN® OEM Embit module which embraces the multiprotocol philosophy in order to be the pillar of Hybrid Networks.
Its transceiver allows the usage of different radio protocols, such as LoRaWAN, LoRa-based custom proprietary D2D (device to device) protocol, WMBus and Sigfox. This enlarges the possible range of applications and enables the possibility to build up an Hybrid Network for asset management.

EMB-LR1121-e is the new LoRaWAN® OEM Embit module which embraces the multiprotocol philosophy in order to be the pillar of Hybrid Networks.
Its transceiver allows the usage of different radio protocols, such as LoRaWAN, LoRa-based custom proprietary D2D (device to device) protocol, WMBus and Sigfox. This enlarges the possible range of applications and enables the possibility to build up an Hybrid Network for asset management.
One of the killer features of the EMB-LR1121-e is the single RF front-end for both 868 and 915 MHz leading to a single SKU which can be use in dirrefert world regions. Moreover, RF interface for 2.4 GHz unleashes the development worldwide applications.
The radio is fully compliant with the worldwide 2.4 GHz frequency band regulation thus being able to operate anywhere in the wold. Moreover, the use of the 2.4 GHz ISM radio band, being not subject to duty cycle restrictions, increasing the overall transmission rate with respect to other sub-1 GHz solutions.
EMB-LR1121-e can communicate with other devices through a wide range of serial interfaces: UART, I2C,SPI, several digital and analog I/O ports useful for the management pf external devices and interfaces. Moreover, the extremely reduced power consumption makes the EMB-LR1121-e particularly suitable to implement long life battery powered devices.
EMB-LR1121-e can be configured as an embedded micro system or simple data modem.
The firmware can be easily developed starting from the Embit SDK. The Embit evaluation kit (EMB-LR1121-e-EVK) contains all the documentation, software and hardware tools to get started with the EMB-LR1121-e module.
The applications of the EMB-LR1121-e are endless; some, of the most popular real-time use cases, are as follows:
- Smart Agriculture
- Smart Cities
- Smart Healthcare
- Smart Environment
- Smart Homes and Buildings
- Smart fire evacuation systems
- Smart Industrial Control
- Smart metering, supply chain, and logistics
