High Capacity Modems, Channel Bonding and New Waveforms
New Solutions for Cruise with Jo De Loor, VP. Business Development at Newtec
As the cruise industry's demand for bandwidth soars, serving this industry presentsgreater and greater challenges to satellite operators and hub and modem infrastructure providers.
There are several requirements that are key to satisfying the cruise customer. Above all is the need to provide a home-like user experience. This involves the need to provide massive throughput, affordability, and delivery of bandwidth capacity wherever a cruise ship is located at any point in time.
For example, a cruise ship might be at sea, near shore, or in port. This means that optimum satellite waveforms need to be deployed based on demand. Also, flexibility is a key concern in serving the connectivity needs of the this community. So, there are several aspects to the challenge.
Essentially, there are two solutions for achieving ultra high capacity using HTS satellites, channel bonding and advanced high capacity modems, and there are several waveforms that can be deployed to maximize efficiency, DVB-S2X on the forward link, and TDMA, Dynamic SCPC and SCPC on the return link.
While channel bonding has demonstrated downlink capacities in excess of 3 Gbps, it generally requires access to more than one satellite which limits its use due to the changing location of the vessel.
That's why it is currently impractical to provide very high bandwidth in this manner, since users would experience significant variability of service from as the vessel transit from one location to another. In addition, channel bonding requires the use of multiple antennas and modems which can be another limiting disadvantage.
With this limitation in mind, Satellite Mobility World spoke to Newtec to see what kind of solutions that can generate maximum throughput from a single transponder, and they were kind enough to put us in touch with Jo De Loor, their VP of Market Development, for a discussion of potential solutions.
