Radio Modules

Under the brand WiMOD IMST developed wireless modules with a wide technical range. The modules are prequalified and working on the license-free ISM frequency bands on 169/433/868MHz and 2.4 GHz. In addition to the hardware we developed our own software stacks for standard technologies like Wireless M-Bus and dispose of a numerousness of proprietary software applications.

Productname   Specification   Description

iM282A LoRa™ Frequency: 2.4 GHz
Range (LoS):up to 10000 m
RF power:up to +12 dBm
Sensitivity:up to -130 dBm

The LoRa® technology of Semtech Corporation provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. The iM282A is especially suitable for battery driven devices. It consumes only 34mA in transmit mode with +12dBm and 25mA @ +8dBm.


iM881A-M LoRa™ Frequency:868 MHz
Range (LoS):up to 12000 m
RF power:up to +14 dBm
Sensitivity:up to -137 dBm

The LoRa® technology of Semtech Corporation provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. The iM881A is especially suitable for battery driven devices. It consumes only 38mA in transmit mode with +14dBm and 25mA @ +10dBm.


iM880B-L

Frequency:868 MHz
Range (LoS):up to 15000 m
RF power:up to +19 dBm
Sensitivity:up to -137 dBm

The iM880B-L is for applications needing ultra longe range and very robust communication. With the implemented spread spectrum technology is it possible to reach sensitivity levels of -137dBm and set up a robust and realible communication link even than you have LTE signal nearby.


iM980A Frequency: 902 to 928 MHz
Range (LoS): up to 15000 m
RF power: up to +17.5 dBm
Sensitivity: down to -137.5 dBm

The iM980A is a compact and low-cost radio module that operates in the unlicensed 915 MHz band and combines a powerful Cortex-M3 controller with the new LoRa™ transceiver SX1272 of Semtech Corporation. A sensitivity of down to -137.5 dBm and a maximum output power of +17.5 dBm results in a link budget of more than 155 dB. The iM980A has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C modular approval in accordance with Part 15.212 Modular Transmitter Statement about FCC.

iC880A Frequency band 868MHz
Orthogonal spreading factors
Sensitivity -138 dBm
Interfaces USB or SPI
SX1301 base band processor
Emulates 49 x LoRa® demodulators
10 parallel demodulation paths

The iC880A is the RF front end of a LoRa® gateway. It is able to receive on different frequency channels at the same time and is able to demodulate the LoRa® signal without knowledge of the used spreading factor of the sending node.

iM240B  

Frequency: 2.4 GHz
Range: up to 700 m
RF datarate: 250 kbps

The iM240B is compatible with standard IEEE 802.15.4 and features an exceptional link budget of 104 dB at a data rate of 250 kbps.

iM222A

iM222A

Frequency: 2.4 GHz
Range: up to 500 m
RF data rate: 250 kbps

ZigBee

The iM222A is a compact, energy-efficient IEEE802.15.4 module operating in the 2.4 GHz ISM frequency band.

iM820A

Frequency: 868 MHz
Range: up to 1100 m
RF datarate: 1.2 kbps – 250 kbps

The iM820A offers permanent wireless availability at a low power consumption of only a few µA. Due to its integrated AES coprocessor, it is suitable for security-relevant applications. Its propagation properties are  particularly appropriate for indoor use.

iM871A

iM871A

Frequency: 868 MHz
Range: up to 3000 m
RF data rate: 4.8/32.768/100 kbps
compliant to EN 13757-4

iM871A offers a cost-effective RF solution for smart metering applications connecting water, heat, electricity and gas meters with data concentrators in the 868 MHz frequency band.
