Cruise Ship Communications for Passengers Is About to ChangePosted by admin on March 11, 2013
Forbes 3/8/13 –
Imagine that you are on a cruise ship in the middle of the ocean, perhaps hundreds or thousands of miles from land, and want to make a phone call or access the Internet. Did you ever wonder how your wireless device works when there are no cell towers or traditional infrastructure available like at home? And more importantly why it does not work better, faster or cheaper for voice and data applications?
The ability to communicate while at sea is incredibly complex and has only been possible and reliable within the past ten years. Unfortunately, the connectivity comes at a steep price because of the high investment required by the cruise lines and satellite carriers who must price access by the amount of bandwidth that is used. It turns out that this is a highly inefficient and costly method to allow passengers and crew to communicate, and the formula is about to change.
While the state-of-the-art has dramatically improved there are still many technical obstacles to achieving the same level of interconnectivity that we experience on land through wired or wireless networks. Cruise ships are seeing dramatic increases in traveler demand for communications services caused by the use of smartphones, laptops and tablets as part of their vacation experience. The bottom line for the consumer is that current cruise communications networks aren’t designed to meet these voracious demands for mobile connectivity.
Consider the following statistics from MTN Communications, one of the biggest sellers of telecom equipment to the cruise ship industry:
Internet Logins – In the past five years, Internet logins on the MTN network almost doubled from approximately 15 million to 27 million per year;
Voice Usage – Based on revenue data over the past five years, voice usage increased approximately 50 percent;
VSAT Bandwidth – In the past five years, bandwidth demand among MTN VSAT (high-speed) customers increased six-fold from 75 Mbps to 475 Mbps per year
Limited bandwidth is still the main reason network speeds, quality of service and data rates are better on land than at sea, coupled with the failure to integrate other technologies that could optimize the transport of large amounts of data by using different networks.
I travel on Holland America Lines which is typical of the cruise industry in terms of its communications capabilities. Virtually all of the fleet has WiFi throughout their ships but it is painfully slow at times which is due to the number of users and available bandwidth. There are also severe limitations on the types of files that can be accessed in order to protect the network and compensate for the bandwidth limitations. Internet access costs between $.25 and $.75 per minute, depending on the selected plan.
Cellular voice and data is available on all ships but is very costly, up to about five dollars a minute through your local carrier, or up to ten dollars a minute if you use Intelsat satellite links through the ship’s voice network. Data connections through cellular can also be very pricy unless you have a data plan. Verizon is the only American carrier that offers a good deal for their customers that use tablets or smartphones on ships. They have a monthly cost of $25 for each 100 Mbytes.
While AT&T has a similar plan it doesn’t allow for data access at sea, which means you can pay around $20 per megabyte. That translates to a high cost for using email and sending pictures, to say nothing of downloading documents. If you try to save money by using a VoIP service such as Skype to make and receive calls you will have limited success because of the latency issues with voice transmission through a satellite, whether you establish a WiFi or cellular connection.
