It costs far less to deploy a wireless LAN than to deploy a wired version. The savings isn’t just in the falling cost of wireless components; it’s in the installation of the infrastructure as well. A major cost of installing and modifying a wired network is the expense to run network and power cables, all in accordance with local building codes. For this reason, WLANs are being installed even when the network is comprised only of non-roaming desktops. Examples of additional applications where the decision to deploy WLANs results in large cost savings include:
- Additions, moves, and changes within an organization
- Installation of temporary networks
- Installation of hard-to-wire locations
- Elimination of costly leased lines
Besides being very simple to install, WLANs are easy to understand and use. With few exceptions, everything to do with wired LANs also applies to wireless LANs. They function like, and are commonly connected to, wired Ethernet networks. They not only free the networked laptop to roam, but dramatically simplify and lower the cost of network deployment.
