- Wi-Fi Protected Access (WPA)
- Wi-Fi Protected Access 2 (WPA 2)
- Wi-Fi Protected Access 3 (WPA 3)
How do you secure a wireless device?
- Change default passwords.
- Restrict access.
- Encrypt the data on your network.
- Protect your Service Set Identifier (SSID).
- Install a firewall.
- Maintain antivirus software.
- Use file sharing with caution.

Which of the following are wireless security tools?
Explanation: A prime branch of cyber-security is wireless security. The most widespread types of wireless securities are Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WPA2 and WPA3.
What are the examples of wireless communication system?
Wireless communication technology transmits information over the air using electromagnetic waves like IR (Infrared), RF (Radio Frequency), satellite, etc. For example, GPS, Wi-Fi, satellite television, wireless computer parts, wireless phones that include 3G and 4G networks, and Bluetooth.
What is the best wireless connection type?
A 5GHz connection will provide better performance at short ranges than 2.4GHz. This is because 5GHz, while somewhat faster, can’t travel as far or transmit through some objects due to that band’s shorter wavelengths.
What is wireless device in computer?
A wireless device has some sort of network connectivity. A cell phone is wireless, and a laptop or PDA would be wireless if they had a wireless modem. Similarly, applications are wireless when they connect and exchange data with a network.
Is laptop a wireless device?
Along with smart phones, tablets and netbooks, laptops are one of the most common devices through which people connect to wireless networks. While most modern laptops come equipped with built-in WiFi cards, a fair number of older models do not.
