Wireless Local Area Networks (WLANs) Certification
About Wireless Local Area Networks (WLANs)
A wireless local area network (WLAN) is a type of wireless computer network that allows devices to connect to a network using radio waves rather than cables. WLANs are typically used in homes, offices, and other small areas to provide wireless internet access to devices such as laptops, smartphones, and tablets.
WLANs operate in the unlicensed 2.4 GHz or 5 GHz radio frequency bands and use wireless network protocols such as IEEE 802.11 (Wi-Fi) to provide wireless connectivity. A WLAN typically includes one or more access points (APs) that act as a hub for wireless devices to connect to the network. These APs can be connected to a wired network, such as an Ethernet network, to provide internet access to wireless devices.
WLANs are widely used due to their convenience, flexibility and cost-effectiveness, they can support a wide range of applications and services, such as internet access, file sharing, and printing. They also have the capability of providing wireless roaming, which allows devices to move around within the network coverage area without losing the network connection.
The security of WLANs is an important consideration, as wireless transmissions can be easily intercepted, and standard WLANs are vulnerable to hacking and other security threats. Therefore, it is important to use encryption and other security measures to protect the data and devices connected to a WLAN.
Who should take the Wireless Local Area Networks (WLANs) Certification exam?
Wireless Local Area Networks (WLANs) course is suitable for IT professionals, network administrators, and wireless engineers who want to gain expertise in designing, deploying, and managing wireless local area networks. The course is also suitable for those who want to improve their knowledge and skills in wireless network technology and security, and prepare for certifications such as Certified Wireless Network Administrator (CWNA).
