Exploring wireless networks, Wi-Fi technologies, and their impact on connectivity.

Wireless networking enables devices to connect without cables, providing mobility and flexibility. Wi-Fi is the most common wireless technology used in homes, offices, and public spaces.

1. Wireless Network Types

  • Wi-Fi (802.11 standards)
  • Bluetooth for short-range communication
  • Cellular networks (4G, 5G)
  • Satellite and IoT wireless networks

2. Wi-Fi Standards

Wi-Fi standards define speed, frequency, and range:

  • 802.11a/b/g/n/ac/ax (Wi-Fi 6)
  • 2.4 GHz and 5 GHz frequency bands
  • Wi-Fi 6E introduces 6 GHz band for faster speeds

3. Wireless Security

  • WEP (deprecated)
  • WPA/WPA2/WPA3 encryption for secure communication
  • Strong passwords and network segmentation

Conclusion

Wireless networking and Wi-Fi are essential for modern mobility, providing high-speed connectivity and enabling smart devices, IoT, and remote work.
