Graduation Project
LoRa Multiprotocol Mesh System
Designed and implemented a multi-node LoRa Mesh network featuring 1 Master (LoRa+GSM) and 2 Slave nodes. Optimized the system to bridge remote areas without cellular coverage by routing local mesh data through a centralized GSM gateway for remote monitoring.
Conducted comparative RF antenna designs for the slave nodes, implementing both internal trace and external SMA antenna configurations. This allowed for performance benchmarking of signal integrity and range efficiency across different hardware form factors.
