XiLAN, a French wireless internet service provider, wanted to offer IPTV over its existing wireless network to remain competitive. It conducted a trial using Cambium equipment and was able to successfully stream high quality video without increasing bandwidth. Customers reported no degradation of the video stream even when using other bandwidth intensive services simultaneously. Based on the successful trial, XiLAN is signing up its first triple play customers and gaining additional revenue streams while ensuring customer loyalty through excellent quality of service across voice, data and video.
