The "Wi-Fi Chat" application is an innovative solution for multi-person communication that operates entirely within a local network without requiring an internet connection. This makes it ideal for environments where maintaining privacy and avoiding data usage is crucial, such as classrooms, MRTs, buses, and libraries.

With "Wi-Fi Chat," all participating devices must have the application installed. Once set up, users can communicate with each other seamlessly using their device's Wi-Fi capabilities. The app supports multiple users in a single chatroom, allowing for real-time conversations and interactions. Additionally, each user can choose a unique nickname and customize the color of their dialog box, adding a personal touch to the experience.

One notable feature is the range limitation, which ensures that communication stays within the confines of the building or immediate vicinity. Specifically, messages can be sent from one device at the center of the building to other devices connected via Wi-Fi. However, if a user decides to leave the chatroom, all participants are automatically disconnected from the conversation.

The advantages of using "Wi-Fi Chat" include:

• No need for an internet connection.
• Support for multi-person conversations.
• Customizable nicknames.
• Personalized dialog box colors.

Overall, "Wi-Fi Chat" is a versatile tool designed to facilitate communication in confined spaces while ensuring privacy and efficiency.
