Wireless Lan And Laptop Computers
A small business run from home or​ on​ rented space,​ while it​ can be extremely profitable,​ cannot be furnished in​ the​ same style as​ a​ large-scale company office .​
Using standard full-size desktop computers in​ such a​ set up is​ impracticable,​ as​ it​ takes up too much space and is​ too bulky for cramped confines .​
To deal with such a​ situation,​ desknotes or​ transportables may just hold the​ key.
Desknotes are systems that can be alternately used as​ a​ standard desktop PC,​ but also offers portability into the​ bargain .​
Desknotes have the​ same power levels as​ a​ desktop PC and occupy much less room .​
Moreover,​ to​ keep expenses to​ a​ minimum,​ it​ is​ possible to​ install a​ LAN amongst the​ desknotes,​ where only one laptop need be connected to​ the​ Internet and access is​ shared to​ all the​ laptops connected to​ the​ network .​
This is​ also true for the​ devices connected to​ the​ central laptop; through LAN,​ all the​ laptops can use the​ same device .​
Thus,​ for small offices with three or​ more laptops,​ LAN (Local Area Network) is​ surely a​ boon.
LANs usually span a​ building or​ a​ small group of​ buildings .​
Connecting one LAN with many others through telephone lines and radio waves is​ called WAN (Wide Area Network) .​
a​ Local Area Network that uses radio waves to​ communicate is​ called WLAN (Wireless Land Area Network) .​
There are several advantages to​ WLANs .​
One is​ its flexibility .​
Radio waves can pass through walls of​ nearly any surface,​ and also do not require miles and miles of​ cables,​ thus offering a​ clutter-free work atmosphere .​
Wireless LAN can be almost invisible!
Another advantage is​ that WLANs are extremely easy to​ use .​
Most laptops are built in​ with WLAN capability .​
So all you need to​ do is​ plug in​ and make sure you have a​ wireless LAN card .​
WLANs are very tough .​
If one base becomes disconnected,​ it​ is​ possible to​ use another laptop as​ a​ base and can be shifted physically into the​ range of​ another WLAN .​
Prices are very low these days for WLAN,​ and it​ is​ no wonder the​ choice for home networks.
However,​ as​ nothing is​ perfect in​ this world,​ WLAN does carry a​ few disadvantages .​
Anyone can operate a​ laptop near a​ WLAN and hack into the​ stored wireless traffic .​
This makes safety an​ issue due to​ the​ loss of​ privacy .​
While radio waves can pass through almost any surface,​ too many obstacles in​ the​ path such as​ buildings can degrade the​ transmission .​
Another drawback is​ the​ data transfer speed .​
As many laptops share the​ same bandwidth,​ data transfer speeds are significantly lower in​ a​ WLAN .​
In addition to​ this,​ wireless data rates fall according to​ signal strength or​ interference.
Wireless LAN is​ convenient where mobility is​ required,​ and is​ the​ only choice in​ old buildings where cables cannot be installed .​
Companies usually provide wired connections for fixed offices,​ and wireless LAN for those users who have no fixed location .​
In the​ end,​ WLAN should be installed only after taking into account all factors regarding your office or​ home set up.
