What is a wireless network?

Wireless network refers to any type of radio computer network, generally integrated with telecommunications networks, and can be linked to each other between nodes without cables. Wireless telecommunications networks are generally used in remote control information transmission systems that use electromagnetic waves, such as radio waves as carriers and physical layer networks.

One of the development directions of wireless networks is "universal wireless network technology", which unifies various wireless networks under a single device. Intel is developing a chip that uses software-defined radio technology to handle different wireless technologies such as WiFi, WiMAX and DVB-H digital TV on the same chip.

Extended information:

Wireless networks are more vulnerable to attacks because anyone can try to hack into the wireless network's signal. Many networks offer Wired Equivalent Privacy (WEP) protection, but it's also quite vulnerable. Although WEP can block some intruders, many companies insist on using wired networks for security reasons until the problem is improved. Another wireless network protection system is WPA (Wi-Fi Protected Access). WPA provides a more secure wireless network environment than WEP, and this firewall can help vulnerable wireless networks patch vulnerabilities.
