Carnival Cruise Lines is the largest cruise line in the world based on passengers carried (3.8 million in 2009). Their challenges are to differentiate guest experience, increase operational efficiency of highly mobile employees and minimize equipment space and power requirements. They chose Cisco to overcome these challenges. They have implemented Cisco unified wireless network that passengers and crew can use for paid Internet access from anywhere aboard ship and provided crew with Cisco unified wireless IP phones 7925G and 7921G, and loaned them to parents of children in camp carnival. The results of implementing Cisco were delighted guests by providing pervasive Internet access, increased Internet access revenues by at least 15% and improved operational efficiency for processes ranging from food replenishment to equipment repairs.
