What Is a Wireless Card?
These days it's all about being mobile, and with wireless notebook cards anyone can connect to the Internet at anytime without having to search for a connection point. These cards have revolutionized the industry and made it easier for anyone to work while on the go.
Function
A wireless card is piece of hardware that is inserted into a laptop computer to allow the user to connect to the Internet from anywhere. Sold by mobile phone companies, wireless cards will grant access as long as the user is within range of a compatible cellular phone tower. The devices make it easy for business men and women to access everything they need while on the go. The are also popular among those who frequently travel or use their computers to telecommute. The versatility of these cards allow users to get away from the office but still be able to stay connected.
Types
There are several different types of wireless cards that can be purchased, and not all are compatible with all computer models. Most cards are small enough not to hamper the user, and take up very little space. There are even smaller versions that use USB ports to connect with the Internet. Before purchasing a wireless card, contact your provider to determine the best choices for your individual computer. Wireless providers are the best place to buy these cards because they require an additional plan to connect to the service. All companies have different plans, so explore your options before making a final decision.
Misconceptions
Many people believe that if they purchase a wireless card from the cell phone provider that they will automatically be able to connect to the Internet, and for many this is true. However, for the connection to work, the laptop where the card is installed must have an integrated Wi-Fi connection. If the Wi-Fi is not integrated, a wireless adapter must be purchased.
Geography
Wireless laptop cards will not work in all locations. Just like mobile phones, they have their limitations. Dead spots occur and you may lose your connection especially if trying to use your computer while on the road. When switching between cell phone towers, the connection may drop, but it usually picks back up quickly. Don't be surprised if you can't get a steady connection in a rural area.
Expert Insight
Since wireless cards require a mobile phone network in order to work, a user must set up an account with a provider such as Verizon, Sprint or AT&T in order to obtain service. Each provider has different plans. Some plans offer unlimited data transfer while others limit the amount of data a user can access each month. Some providers offer discounts to customers that already have voice plans with their company. All new users are required to sign up for a 2-year contract with the provider and must agree to a credit check to obtain service.
