Skysens Network Technology
What is LPWAN?
Low Power Wide Area Networks (or LPWAN in short) are a wireless communication technology group. Specifically designed for low energy consumption and long range connectivity for small sensor based data.
Since there are and will be tens of billions of sensors on the field and overwhelming majority of this sensors is sending very small data over wireless networks, LPWAN technologies cover a large portion of the IoT market.According to James Brehm & Associates research in 2015, more than 80% of all sensory devices transmit 2MB or less per month.
Because these technologies works with very little data rates and low power, hardware for these systems can be very low cost in bulk and system can rely on low cost infrastructure. Also, long range and long battery live means very easy setup which means lower engineering and labor cost. In addition to that, native integration between device and platform means standardized integration means no middle-ware cost for data change.
LPWAN technology group basically divide by two, cellular network based and non-cellular based. In cellular group LTE-IoT (LTE-M and NB-IoT) is on the headlines , these technologies are basically version updates to existing GSM infrastructure and that is why it has been liked by many MNO (Mobile Network Operators) around the world. However even though those technologies are optimized for low cost, low power sensor communications, they still carry most of the GSM technology overhead such as static network structure, long and complicated protocol stack and service costs. Also due to bigger power consumption over non-cellular based LPWAN , end device hardware is more expensive.
Unlicensed LPWANs are several , but biggest and most prominent player is LoRaWAN. LoRa is Semtech trademark,physical RF layer, which defines physical RF communication with chirp spread spectrum modulation technology. LoRaWAN is protocol designed by LoRa Alliance which is open global technology alliance.

Using LoRaWAN for Industrial Requirements
Skysens Network Stack has multiple different layers of algorithms in order to make LoRaWAN protocol industrially robust, easy to use for the application users and better capacity in terms of the data transmission intervals and battery live.
LoRaWAN is an open protocol defined by LoRa Alliance and being used world wide for many different applications mostly for smart city vertical. Protocol provides multiple layers for compatibility between devices, networks and applications also being updated with the best practices around the world. This protocol provides open ecosystem and enables users to reach many different applications and hardware compatible to each other.
However , standard stack of LoRaWAN does not specify how you should use the network in order to provide most efficient connectivity layer for your wireless sensor application. Because every application requires different network usage and hardware in the system is working with low power and low cost, network needs to be managed with optimized manner.
Skysens Robust Sensory Network for Enterprises
Skysens Network Stack provides multiple different layers of algorithms in order to make LoRaWAN Technology more robust for industrial environment.Industrial environments mostly requires higher QoS (Quality of Service), higher data rates and better power consumptions.
For many different sensors on the field, managing RF layer means easy access to sensor-platform communication architecture for users, which means according to environmental and capacity changes network can fine-tuned and remotely configurable. With sensor deployments which are smaller than 5 sensors, configuration capability of the network adds up huge advantage for system usability.
AI Enhanced Wireless Network Management
LoRaWAN open protocol provides multiple configuration options for network management. Configuration parameters such as spreading factors, frequencies, data intervals, selection of acknowledged message schemes, payload length needs to be managed in order to maximize QoS, capacity and battery life. However, network operators needs to manage those parameters according to their expertise and knowledge.
Industrial environments may change rapidly and requirements may differ widely. In order to coop with this change, network management need to be smart. Skysens AI Enhanced network management technology provides best configuration possible every time in order to maximize network for enterprises in IoT.

Skysens Light Client
Skysens provides light client network server for software on premises requirements. Network server works on small resources on server on premises or industrial pc which provides the running environment. With this, it is easily to integrate automation infrastructure even if there is no internet access with Modbus TCP or SQL database integration to legacy networks.
Profiling for Different Applications - Not Every LPWAN Application is Same
Different applications require different network profile. For example , medical call buttons are life depending applications and data needs to be sent every time with 100% QoS, however, they are not being used frequently.For remote metering, data intervals can be every hour but it is usually accaptable to loose some package on the way in sake of long battery live. Skysens network platform manages these different application profiles according to user requirements.
