Issues in Wi-Fi Deployment

As convenient and useful as a wireless network is, there are a number of
significant limitations that will affect the ways in which you can share
your mission-critical data. Most WLANs work in tandem with wired networks
in an effort to easily expand internal network coverage as departments
grow or add new employees.
Wireless application deployment  uses the 802.11 wireless
standards for items including:


Collaborative code building

Remote monitoring of the facilities

Mobile access to database applications

Mobile computer-based training (CBT) applications

Wireless video distribution

The evolution of multimedia-rich applications requires higher bandwidth
hardware for the wireless deployment of all the above applications.
The current popular standard, 802.11b, is hindered by its speed
barrier of 11 Mbps. This speed is really insufficient to run modern applications,
thus initiating the need to move to the higher-speed standard of
802.11a, which supports speeds as high as 54 Mbps.
