Wireless technology depends on wireless access points or a wireless router to send and receive these signals wirelessly to and from a laptop through the wireless device attached to it. A practical distance limitation exists between a laptop’s wireless connection interface and the nearest wireless router or wireless access point for wireless technology to work.

Laptops can be used to access the Internet and connect to Bluetooth enabled devices and wireless office networks wirelessly. Wireless technology uses RF signals transmitted over air. A wireless device is attached through a laptop wireless connection interface to a laptop.

In the case of both wireless Internet access and wireless access to a wireless office network from a wireless laptop, this distance limitation is normally 300 feet.

This can be extended through an external wireless RF signal booster antenna attached through a suitable interface on a laptop to about 3 miles. This antenna can also be termed as a laptop wireless booster. The wireless antenna uses signal gain control technology to extend the range of transmission of RF signals.

The wireless LAN or wireless LAN card alternatively on the laptop needs to be switched on and correctly configured as some of the prerequisite conditions for this connectivity.

An option for laptop wireless connection to the Internet can be an external USB wireless modem attached on a USB port of a laptop.

Bluetooth technology is a special application of wireless technology. It uses short-range RF signals at 2.4 GHz to achieve wireless signal transmission within a distance ceiling of 10 meters.

Through Bluetooth technology, a laptop equipped with an integrated Bluetooth adaptor (laptop wireless connection interface) can be wirelessly connected to Bluetooth enabled cellphones or barcode readers or to a Bluetooth base station within the prescribed distance limitation and data or files shared or transferred mutually between the synchronized devices at the two ends of the connection..

For the above to be achieved in practice, Bluetooth adaptors on devices at both ends of the connection need to be switched on and the necessary password permissions assigned on these devices.

The major advantage of a laptop wireless connection is ‘on the move’ seamless connectivity to the Internet, to wireless office networks, and to similarly equipped Bluetooth devices from a laptop. This provides convenience and independence to a mobile laptop user.

The benefits of a laptop wireless connection are manifold. Some of them include complete avoidance of unwieldy, expensive, and problematic wired connectivity on a laptop to achieve the same tasks, and wireless connection sharing facility among two or more laptops.

In the case of wireless connectivity to an office network from a laptop, wireless LAN on the laptop connects to a wireless office network through the internal antenna of an onboard integrated wireless LAN if so available on the laptop or alternatively through the antenna on the wireless LAN card if so available and inserted on the PCMCIA slot of a laptop.
