Wireless LAN And Laptop Computers
A small business that is run from home or in a rented room, although it can be very profitable, cannot be equipped in the same style as a large-scale corporate office. Using a standard full size desktop computer in such settings is not practical, because it takes up too much space and is too large for a narrow space. To deal with such situations, table records or transportable items may only hold keys.
Description is a system that can be used interchangeably as a standard desktop PC, but also offers portability into bargaining. Desk has the same power level as desktop PCs and occupies much less space. In addition, to keep expenses to a minimum, it is possible to install a LAN between desktops, where only one laptop needs to be connected to the Internet and access is shared to all laptops connected to the network. This also applies to devices connected to a central laptop; through LAN, all laptops can use the same device. Thus, for a small office with three or more laptops, LAN (Local Area Network) is definitely a gift.
LANs usually reach a building or a small group of buildings. Connecting one LAN with many others through telephone lines and radio waves is called a WAN (Wide Area Network). Local Area Networks that use radio waves to communicate are called Wireless Area Area Networks (WLANs). There are several advantages of WLAN. One of them is its flexibility. Radio waves can pass through walls on almost any surface, and also don’t require miles and miles of cable, offering a clutter-free work atmosphere. Wireless LAN is almost invisible!
Another advantage is that WLAN is very easy to use. Most laptops are integrated with WLAN capabilities. So what you need to do is plug in and make sure you have a wireless LAN card. WLAN is very powerful. If one base becomes disconnected, it is possible to use another laptop as a base and can be physically shifted into the reach of another WLAN. Today’s WLAN prices are very low, and it’s no wonder the choice for home networks.
However, because nothing is perfect in this world, WLAN does carry some weaknesses. Anyone can operate a laptop near WLAN and hack into stored wireless traffic. This creates a security problem due to loss of privacy. While radio waves can pass over almost any surface, too many obstacles on the road such as buildings can reduce transmission. Another disadvantage is the speed of data transfer. Because many laptops share the same bandwidth, data transfer speeds are significantly lower in WLAN. In addition, wireless data rates drop according to signal strength or interference.
Wireless LAN is convenient where mobility is needed, and is the only choice in old buildings where cables cannot be installed. Companies usually provide wired connections for fixed offices, and wireless LANs for users who do not have a fixed location. In the end, WLAN must be installed only after taking into account all the factors associated with your office or home settings.
