A wireless notebook computer connects to a wireless network using a network card. Most modern notebooks have an integrated card, and older ones can be retrofitted. Wireless laptops are popular for their mobility and use WiFi signals regulated by the IEEE 802 standard. The letters (b), (g), or (n) represent different generations of technology with later letters being faster. Most laptops have the ability to turn off the wireless signal to save energy or prevent unauthorized access. The wireless notebook is a standard for all notebook computers and is available at a relatively low price.
A wireless notebook computer is simply a computer equipped with some type of network card so that it can connect to a wireless network. Most modern notebooks come with a wireless card already integrated internally. Those that don’t have a card can often be retrofitted with one so that connectivity can still happen once the software is installed so the card can interface with the computer.
The wireless laptop has become popular in recent years simply because of the mobile computing capability that comes with it. In the past, it was difficult to be very mobile even with laptops due to the fact that internet connectivity was still very fixed in certain locations. Often, these positions involved wires. The advent of wireless networks changed everything.
To connect to a wireless network, most wireless notebooks use a wireless card that can receive and send so-called WiFi signals. These signals are regulated and standardized by the Institute of Electrical and Electronics Engineers in the so-called section 802 of their uniform code. Therefore, any WiFi product is likely to be referred to as 802. More specifically, WiFi uses 802.11. Anyone buying a wireless notebook computer will also notice a letter behind the number, probably a (b), (g), or (n).
For those who are just using their wireless notebook to connect to the Internet, these letters probably won’t mean much. However, they represent different generations of the technology, with later letters being newer technologies capable of going at higher speeds. However, for those who have a wireless laptop capable of sending and receiving in the 802.11(b) standard, any router intended for later generations is usually backwards compatible with the standard required by the computer.
Most laptop models will have the ability to turn a wireless signal on and off as needed. This can help save energy when running on battery power. Also, for those worried about other people accessing their machine over a wireless network, this is a good way to make sure that doesn’t happen. The computer may have a manual switch that can be flipped to break the signal, it may use software to break the signal, or it may offer both.
For those who require wireless connectivity as a priority but don’t really need a fast machine, the wireless notebook offers an edge. Almost all notebooks take advantage of the same technology, available at a relatively low price. This is one of the reasons why it has become a standard for all notebook computers.
