Network Communications
Wireless Networks
A wireless LAN provides the same functionality of a wired network,
but it eliminates the need to install networking cables and other
networking equipment, making it easier to deploy.
A wireless LAN can be configured for two different modes of
operation. While each method has its advantages, one may be better
suited for your needs. Review the following configuration
information to determine which mode is best for you.
■ Ad-hoc Network
■ Access Point (Infrastructure) Network
Ad-hoc Network
An Ad-hoc network is the simplest to deploy and is ideal for small
offices. Ad-hoc wireless networks can be comprised of two or more
wireless clients configured to communicate with one another. All
Ad-hoc clients communicate directly with each other without using
an Access Point (AP). As a user on this type of network, you are able
to quickly build up a wireless network in order to share files with
other employees, print to a shared office printer, and access the
Internet through a single shared connection.
Ad-hoc networking is cost effective because no other devices’
components are needed (access points, hubs, or routers) in order to set
up a network. However, with Ad-hoc networking, your computer is
only able to communicate with other nearby wireless clients.
Access Point (Infrastructure) Network
An Access Point network is also referred to as an “Infrastructure”
network. The key difference between a wireless Access Point
network and an Ad-hoc network is the addition of one extra
element—the Access Point. The Access Point serves as the focal
point for all data traffic on your wireless network, optimally
managing all wireless data transactions.
The Access Point extends the range of the wireless LAN. Each
wireless client computer can communicate with other computers
equipped with wireless devices that are within the range of the Access
Point.
