Applications that businesses use the most to enhance productivity and trim costs are changing dramatically. SMB owners are moving beyond the straightforward low-bandwidth applications that ran their businesses just a few years ago to higher-bandwidth, business-critical multimedia applications and Software as a Service (SaaS) models that are network-intensive and time-sensitive. These applications, including videoconferencing, mobility, IP telephony, and distance learning, have potential to improve employee productivity, promote market growth, and reduce costs.
