How it Works When the Android Hotspot feature is enabled, the device creates a Wi-Fi network that other devices can connect to. The connected devices can then access the internet using the Android device's data connection. The Android device acts as a router, assigning IP addresses and managing the connections. Benefits The Android Hotspot feature provides several benefits to users, including: Convenience: Users can share their internet connection with others without having to carry a separate Wi-Fi router. Cost-effective: Users can save money by sharing their data plan with others instead of purchasing separate plans for each device. Easy setup: The feature is easy to set up and use, requiring minimal configuration. Security Concerns As with any Wi-Fi network, there are security concerns associated with using the Android Hotspot feature. Users should be aware of these risks and take steps to secure their connection, such as: Setting a strong password for the Wi-Fi network. Enabling WPA2 encryption. Limited access to sensitive information while connected to the hotspot. Using Mobile Hotspot on Android Devices Easily With the increasing demand for internet connectivity, mobile hotspots have become a necessity. Android devices offer a built-in feature to create a mobile hotspot, allowing users to share their internet connection with other devices.

Enable Mobile Hotspot Go to Settings > Connections > Mobile Hotspot and Tethering The Android device will create a virtual Wi-Fi interface (wlan0) and assign an IP address from the 192.168.43.x subnet. The device will also start the dhcpd service to manage IP addresses for connected clients. 2. Configure Mobile Hotspot Settings Set the Network name (SSID), Security type, and Password The Android device will generate a WPA2-PSK encryption key and store it in the /data/misc/wifi/ directory. The device will also create a hostapd.conf file to configure the access point. 3. Start Mobile Hotspot Toggle the Mobile Hotspot switch to ON The Android device will start the hostapd service, which will read the hostapd.conf file and configure the wireless interface (wlan0) as an access point. The device will also start the dnsmasq service to provide DNS and DHCP services to connected clients. 4. Connect Clients Other devices can connect to the Mobile Hotspot using the configured SSID and password The client device will send a probe request to the Android device's access point, which will respond with a probe response containing the SSID and supported rates. The client device will then authenticate with the Android device using WPA2-PSK, and obtain an IP address from the dhcpd service. 5. Manage Data Usage The Android device can monitor data usage and set limits for connected clients The Android device will use the netfilter framework to track data usage for each connected client, and enforce any configured limits using the tc (traffic control) command.
