Chapter 18. Wireless Networking
Wireless networking is a promising and increasingly popular
technology, offering a wide range of benefits compared to traditional
wired technology. These advantages range from increased convenience
to users and decreased deployment cost to ease of network
installation. A new wireless deployment can save substantial amounts
of money since there is no need for additional cables, jacks, or
network switches. Adding new users to a network can be as easy as
plugging in a wireless card and powering up a machine. Wireless
networking has also been used to deliver network access to areas
where there is little or no traditional network infrastructure.
Perhaps the biggest impact of wireless
networking can be seen within its widespread acceptance among
consumers. The most obvious example of this popularity can be seen
with new laptop systems, where nearly every unit is shipped with
integrated 802.11b or g. The practical benefits have consequently
insured good sales, allowing manufacturers to lower the equipment
costs. At the time of this writing, the price of client wireless
cards is comparable to that of traditional Ethernet adapter cards.These benefits, however, do not come without some disadvantages, the
most severe of these being the security issues.
