Wireless presentation systems (WPS) are an affordable way of keeping businesses from losing costs on meetings and improving meeting start-up times. However, there are now several options available, which can make it very complex to determine what’s the best buy for an organization. By applying the techniques in the IT-accepted Gartner total cost of ownership (TCO) model, organizations can identify the specific costs that should be used to compare the button-type transmitter and receiver systems, such as BenQ’s InstaShow, and Wi-Fi network hub wireless systems. From an IT perspective, there are three costs to consider: setup costs, recurring costs that are tied to labor and maintenance, and other soft costs. Based upon the time it takes internal IT staff to execute the most common tasks at a billable rate of $50 per hour, these costs can be estimated for WPS.
