A survey by wireless networking firm
AirMagnet found that 43 percent of companies which have so far resisted wireless adoption in the workplace are concerned about how to ensure the network's security.
A further 29 percent are delaying implementation because they perceive wireless Lans to be slower or less reliable than traditional wired networks.
However, the study reports that benefits are being felt by business which have already made the transition to wireless.
Almost two thirds of those already using the technology said that they intend to increase investment in wireless networks in the future.
Ian Schenkel, EMEA managing director at AirMagnet, said: "The research demonstrates that, although many companies have moved to a combination of wired and wireless networks to increase employee productivity, incorrect preconceptions are continuing to hold many more back.
"This means that most are still missing out on the increased productivity, mobility and convenience delivered by wireless networks.
"The security concerns expressed by respondents are easily addressable using a variety of methods. For example, point monitoring using a mobile device or laptop solution allows users to identify isolated risks.
"Ad hoc or continuous monitoring with an enterprise-level tool which alerts users to any potential threats or security weaknesses, in some cases proactively scanning the network for potential issues, adds a further level of security to protect users."
