A wireless local area network (WLAN) does not require a wired internet connection. WLAN can be an extension or replacement of an existing wired network. Wireless data rates range from 1 to 54 Mbps, and some manufacturers offer proprietary 108 Mbps solutions. The 802.11n standard provides speeds between 300 and 600 Mbps.
Because the radio signal is transmitted so everyone in the vicinity can share it, a series of security measures are required to ensure that only authorized users have access to the WLAN.
The wlan working signal can stand inspired by a small office to a large campus. Most commonly, a Wi-Fi access point allows access in the range of 65 to 300 feet.
A private home network or small WLAN typically, your home or business WLAN uses one or two access points to broadcast signals within a radius of 100 to 200 feet. You can find home WLAN installation equipment in many retail outlets.
With a few exceptions, this category of equipment meets the 802.11a, b, or g standards (also known as Wi-Fi); some home and office WLANs are now up to the new 802.11n standard. For security reasons, many home and office WLANs are Wi-Fi Protected Access 2 (WPA2).
Enterprise-class WLANs use a large number of individual access points to transmit signals over a large area. Access points have more features than WLAN devices in your home or small office, such as better security, authentication, remote control, and tools that make it easy to integrate with existing networks. These access points are more extended than home appliances or small offices and are designed to work together in a much larger area. This device may be in compliance with 802.11a, b, g, or n standards or with security enhancements such as 802.1x and WPA2.
What Does WLAN Mean?
Network security remains an essential topic for WLANs. Wireless clients usually verify their identity (a process known as authentication) when they connect to a wireless LAN. Technologies like WPA increase the level of security in wireless networks compared to traditional wired networks.
A WLAN can contain only two methods, or even one hundred or more. However, wireless networks are becoming mildly challenging to manage as the number of devices increases.
WLANs can contain many types of devices, including:
- Mobile phones
- Laptops and tablets
- Internet audio systems
- Game consoles
- Other household appliances and equipment with Internet access WLAN equipment and connections
WLAN connections work by using radio transmitters and receiver built-in client devices. Wireless networks do not require cables, but some individual devices (including their radio and antenna receivers) are usually used to make them.
For example, you can build local Wi-Fi networks in one of two settings: ad-hoc or infrastructure.
The Wi-Fi setting in select wireless LANs consists of direct peer-to-peer connections between customers without indirect hardware. Local ad-hoc networks can be used to make temporary connections in some situations, but they are of no size to support more than one device and can provide security.
Wi-Fi WLAN infrastructure mode uses a nuclear device called a wireless access point (AP) that all customers connect near. Home networks, wireless broadband devices act as an access point and allow access to your wireless LAN through a wireless LAN. You can combine multiple access points to one and connect multiple WLANs to larger ones.
Some wireless LANs extend the existing wired network. This type of WLAN is built by connecting an access point to the edge of the wired network and setting the access point to operate in bridging mode. Customers interact with the access point through a wireless link and can access Ethernet via the AP bridge connection.
Differences between Wlan and Wwan
Cell networks support mobile phones that connect over long distances, a type of wireless extensive area network (WWAN). What distinguishes a local system from a vast network are the usage models they support along with some rough limits on physical distance and area.
A local area network covers individual buildings or public hotspots, spanning hundreds or thousands of square feet. Extensive area networks cover cities or geographic regions, spanning many miles.
