USE CASES AND USER EXPERIENCE

The following section outlines the testing performed with different types of USB devices, illustrating the use case and describing the measured performance.

MULTI FUNCTION PRINTER

Testing was performed first with a USB cable, then with the adapter set, connected to an HP All-in-One printer (model C8180). For wireless, the printer was placed in one side of a meeting room, and files were sent to print from a laptop, while sitting at the other side of the room. In addition, testing was performed for wirelessly scanning and reading data from the printer’s built-in card reader.

Two measurements, commonly used by the print industry, were used: first page out (measuring the time from sending the file from the printer till the first page completes printing) and Pages per Minute (PPM).

The table below shows that there was hardly any difference in user experience between wired and Wireless USB connectivity. Also note that wireless performance remains the same when increasing the distance from 3 meters to 8-10 meters.
