Updating wireless adaptor
Because the wireless network exists to serve the user, the user is the component that receives the benefits of a wireless network.As a result, users are an important part of the wireless network.
Some of these elements overlap with those of wired networks, but special consideration is necessary for all of these components when deploying a wireless network. Figure 2-1 Wireless Networks Include Computer Devices, Base Stations, and a Wireless Infrastructure A user can be anything that directly utilizes the wireless network. For example, a business traveler accessing the Internet from a public wireless LAN at an airport is a user.For example, a person walking through a convention center while sending and receiving e-mail from a PDA is exercising mobility.The PDA in this case must have continual or frequent connections to a wireless network infrastructure.Some users might require only portability; whereby, they stay at a particular location while using the wireless network for a specific period of time.An example of this type of usage is someone operating a laptop wirelessly from a conference room.These devices generally have larger displays and keyboards, making them more suitable to use when browsing the Internet and other applications requiring relatively high performance.
The problem, however, is that these devices weigh more and are difficult to carry from one place to another.
The user will turn on the laptop after sitting down in the conference room and shut off the laptop before leaving.
As a result, the wireless network doesn't need to support continual movement.
Apart from transmitting the information over the air, wireless networks are very much like wired networks.
However, that seemingly small difference can lead to some very large problems if you don't understand the nuances of this medium.
Many types of computer devices, sometimes referred to as clients, operate on a wireless network.
