Within two to five years, businesses will be able to give users a single wireless computing device that they can carry everywhere to access corporate IT, Gartner predicts.
Developments in the network infrastructure to support fixed-mobile convergence will enable users to access IT systems from one device, said the analyst firm.
Mid-sized and large businesses are already providing end users with wireless e-mail through devices such as the Blackberry.
But some organisations, such as the University of London Computer Centre, are starting to use wireless networks to enable staff to access back-office systems from mobile devices.
Gartner predicted that the Session Initiation Protocol (SIP) used in VoIP systems will become the glue that joins different networking environments together, to enable wireless access to corporate IT.
SIP allows IT directors to roll out communication-enabled business processes. Gartner said it could be used to build more effective work processes and allow companies to make better use of collaborative and multimedia applications.
The adoption of wireless devices in business will depend on whether users accept the technology. Gartner urged IT directors to evaluate staff preferences and expectations, in terms of the devices, applications and services they needed to perform their job, when planning for wireless e-mail deployments. Successful mobile deployments would depend on ease of use of the devices and applications, security, manageability and cost, it said.
