Mobility equates to nearly 30% of North American and European enterprise telecom budgets today, with that percentage set to grow.

To push mobility beyond its current state, tech marketers must sell companies a smooth transition to ubiquitous computing. Leading mobility vendors will help firms create a holistic enterprise mobility strategy that integrates wired and wireless networks, bridges voice and data services, and extends beyond basic email access to business process transformation.
