   Sammanfattning : The Internet of Things holds great promises for the future. In the smart cities of tomorrow, wireless connectivity of everyday objects is deemed essential in ensuring efficient and sustainable use of vital, yet limited resources such as water, electricity and food. However, radio communication at the required scale does not come easily. LÄS MER

3. 12. Virtualizing LoRa baseband functionalities to the Edge

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Patrik Vijayendra Walvekar; [2019]
   Nyckelord :;

   Sammanfattning : Traditional network architecture design of Low Power Wide Area Networks (LPWAN) suffer from their inability to dynamically scale resources based on the incoming traffic and involve manual procedures for capacity upgrades. There is a need to develop a cloud-native architecture where the gateway hardware performs signal detection while baseband processing is virtualized in the Edge, provisioning for dynamic scaling of resources.
