Discuss the two technologies to connect to Internet wirelessly.

Two most common ways to connect to Internet wirelessly are :

1. Wi-Fi — Wi-Fi refers to Wireless Fidelity, which lets us connect to the Internet without a direct line from our PC to the ISP. The WiFi wireless local area network standard is limited in most cases to only 100-300 feet (30-100 m). For Wi-Fi to work, we need:
   
   1. A broadband Internet connection.
   2. A wireless router, which relays our Internet connection from the ISP to the PC.
   3. A laptop or desktop with a wireless internet card or external wireless adapter.
2. WiMAX — It is a wireless digital communications system. It can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3-10 miles (5-15 km) for mobile stations.
