Wireless Hot Spots on the Rise
According to research firm Gartner Inc., the number of public wireless LAN (WLAN) hot spots is on the rise. In 2001, there were just over 1,200 public WLAN hot spots. As of 2003, there are more than 71,000. Despite this increase, there are still not enough hot spot locations to meet user requirements.
In 2003, Gartner predicts that the number of WLAN hot spot users will reach 9.3 million worldwide. This is up from only 2.5 million in 2002. Nearly 5 million of those users will be in North America, followed by Asia Pacific, which will have nearly 3 million users. By 2004, Gartner said, more than 50 percent of professional notebook PCs will be WLAN-enabled. Workers with WLAN-enabled notebook PCs will be eager to use hot spots to synchronize their e-mail or download files while away from the office.
As the use of wireless technology increases, IT professionals need to make sure they are prepared with the knowledge and expertise to handle these technologies. Wireless technologies present unique challenges for IT professionals, specifically around security issues. Look for a growing number of certifications that focus on wireless technologies and get ready to incorporate this expertise into your skill set.
