Dr. Roger Sanchez Vital

Postdoctoral Researcher · Universitat Politècnica de Catalunya

I am a Postdoctoral researcher at the Universitat Politècnica de Catalunya (UPC), a member of the Wireless Networks Group within the Network Engineering Department. I received my PhD and B.Sc. in Network Engineering from UPC in 2025 and 2020, respectively. I also hold an M.Sc. in Telecommunications Engineering from La Salle - Universitat Ramon Llull (2021).

My research focuses on energy-efficient wireless networks and the IEEE 802.11 standard. I am particularly interested in IoT-related technologies, Wake-up Radio (WuR) systems, LoRaWAN, LR-FHSS, and power-saving mechanisms for next-generation wireless protocols.
