900MHz LoRa technology module

The MultiConnect mDot™ is a secure, programmable, long-range and low-power RF module
that provides data connectivity to sensors, industrial equipment and remote
appliances. By employing the Semtech LoRa™ Long Range Spread Spectrum
technology, bi-directional data communication can be maintained over 10 miles /
16 km, deep into buildings and within noisy environments using the unlicensed
ISM bands in North America, Europe and worldwide. The mDot features an
integrated ARM Cortex -M4 processor and mbed compatible software library for
developers to control, monitor and bring edge intelligence to their Internet of
Things (IoT) applications.

LoRa Gateway

LoRa™ technology enables
10-times greater range than competing systems and the capacity to connect tens
of thousands of nodes to a single gateway in a star architecture while
maintaining low power consumption for multi-year battery operation. This
combination of benefits enables the next wave of IoT applications for smart
cities, smart environments and other M2M applications.

MultiConnect Conduit™ – MTCDK is a
programmable industrial grade IoT Gateway which embedded with cellular LTE/3G
option for Semtech LoRa based wireless sensor networks. With the Linux
development platform and Node-RED development platform option, MultiConnect
Conduit™ is the most configurable, manageable and scalable communication
gateway for realising your IoT applications. MTCDK is not a limited gateway for Cellular connection, but
developers could embed Ethernet, WiFi, Bluetooth, CAN, GPS or other
technologies into the two accessories slots. By applied, two LoRa card inside
the gateway, developer could extend the LoRa infrastructure network for their
