"Web 2.0, .Net, Java, wireless -- skills in technologies that enable end users to engage and communicate with each other -- are hot," says Rich Milgram, CEO of online job portal Beyond.com. "At the same time network and security skills are becoming more and more important, especially as companies expose more and more of their networks and data to the world."

Here we examine (in no particular order) the current most-sought-after skills and those destined to be in demand going forward.

1. Wireless

Because end users expect to be able to work from anywhere anytime, skills in wireless and mobility are being pushed to the top of many hiring managers’ must-have lists.

"Now you need to be able to plan and troubleshoot radio interference and access point placement. Everyone wants to work from anywhere," says Bruce Meyer, director of network services at ProMedica Healthcare in Toledo, Ohio. "Standards will continue to evolve rapidly as everyone chases the Holy Grail of a wirelike experience. I’m not just looking for wireless skills; I’m looking for the ability to rapidly learn new things."

According to CompTIA, wireless skills in many areas -- 802.11, WiMAX  and broadband -- will only become more appealing to companies in the next five years.

John Estes, vice president of strategic alliances at Robert Half Technology, adds that mobility goes beyond knowing wireless technologies. It also requires knowing about each device end users might start using to tap the network. "End users have mini multimedia computers in their hands now. Someone is going to have to be involved in decisions around which devices best suit the environment and application needs," Estes says.
