SOHO network using Cisco packet tracer and LoRa

Small Office Home Office (SOHO) network is a small LAN network. Cisco packet tracer permits us to build a network and test the communication among them. Here in our paper, we have built a network for inter-departmental communication, providing a WIFI and password. After getting confirmation on the communication between devices, we built a network using 3 LoRa – O2 devices representing 1 admin and 2 departments. Using Arduino Nano and ESP32 to establish a connection between different components, two-way communication is established (Admin to the department and inter-department). The LCD display shows us the no of packets transferred, the message sent, and the signal strength. This paper gives a rough idea of how wireless communication can take place between the devices and the departments of a small company.
