| Abstract: | : | The Internet of Things (IoT) is scaling rapidly to billions of low power devices, with diverse radio technologies sharing common unlicensed spectrum (868MHz EU band and 900MHz US band). Inevitably, this require solutions to two key challenges- provision of seamless connectivity across diverse radio standards, and handling rampant cross-technology collisions. With the lack of standardization, enabling connectivity to every new radio technology introduced into the existing IoT paradigm requires replacing or modifying the existing receiver hardware, hence being cost inefficient. In addition, hardware/ software modifications are proposed in these receivers to deal with packet collisions, the effect of collisions being wasteful re-transmissions which drain the battery life of low-power devices significantly. We develop a simple, cost-effective, universal IoT gateway platform using commodity hardware that offers scalability across radio technologies using simple software updates at the cloud. These gateways can effectively receive and decode packets stemming from diverse radio technologies thereby enabling seamless connectivity. We show how a scaled deployment of these gateways can implement a cross-technology distributed MIMO setup, which can effectively resolve collisions within and across these low power transmissions. |
