LPWAN platform
NWave’s LPWAN platform for the IoT combines high transmission ranges of up to 10km in urban environments with low power consumption, allowing devices to operate without maintenance or battery change for many years. We provide a full platform including sensors and devices for parking, agriculture and metering, radio modules for integration into 3rd party devices, universal modems, base station receivers, and advanced services in the cloud.

IBM Long-Range Signaling and Control (LRSC)
Driving the revolution of online data to a next level, more and more devices will be Internet-connected. For example, according to Forrester, more than 22 billion devices will be connected by 2020. Given that this number far outstrips mobile (GSM) subscription estimations for 3G or 4G networks, there is one key question to be answered: How can this be made possible in a sustainable and scalable manner, e.g., without deploying 2–3 times more GSM base stations or routing billions of new machine-to-machine (M2M) interactions over private WLAN hotspots?
One answer to this question is by using a long-range, low-data-rate communications infrastructure that needs fewer base stations to serve more simple devices like online smoke detectors, temperature sensors or smart electrical heating controllers.
Several such radio technologies exist and our team has created the necessary IT infrastructure to render one such radio technology to be easy to deploy.
SX1272/76 radio drivers plus
Ping-Pong firmware and LoRa MAC node firmware implementation
1. Introduction
The aim of this project is to show an example of the LoRaMac endpoint firmware implementation.
Next version of the project will include big changes.
REMARK 1:
This is the last version based on the Semtech LoRaMac implementation. The next version will be based on the IBM 'LoRaWAN in C' implementation.The IBM 'LoRaWAN in C' implementation adds the support of the Class A endpoint fully implemented and Class B endpoints.The biggest change resides on the MAC layer API which is completely different.REMARK 2:REMARK 3:
By default the LORAMAC_R3 compiler option is enabled. Disabling this option will enable LoRaMac specification R2.2.1
This is a Class A endpoint.
Implements version R3.0 of LoRaMac specification.
2. System schematic and definitions
The available supported hardware platforms schematics and LoRaMac specification can be found in the Doc directory.

5. Usage
Projects for CooCox-CoIDE (partial), Ride7 and Keil Integrated Development Environments are available.
One project is available per application and for each hardware platform in each development environment. Different targets/configurations have been created in the different projects in order to select different options such as the usage or not of a bootloader and the radio frequency band to be used.
