ROV Operation

Special thanks to Stuart Wilson for confirming that the first videos I mentioned in this and this post are from GMSL.

The following YouTube animation video is also from GMSL, showing a ROV (Remotely Operated Vehicle) in operation.

Submarine Cable Protection

The following YouTube video shows a way to protect submarine (telecommunication) cable. Anybody knows source of this video?

Submarine Cable Laying

If some days ago I mentioned two videos illustrating submarine cable repair/maintenance, this time I would refer to two other videos showing a basic scheme for submarine cable laying. As before, the first video is 3D (from GMSL??) while the second one is in the ASN fashion.. :-D

Internet : How It Works

How does the Internet work? The following two videos are good introductory material for answering that question. We used those for introducing our Department at TUHH to new undergraduate students. And couple of times I used also at ITB for the same purpose. The fist video (Warriors of the Net) is made by Ericsson MediaLab (?), narated in English and it's also available for download in several languages. The second video (Die Maus erklaert das Internet) is an episode from the "die Sendung mit der Maus" from the german WDR TV-broadcaster (sure, it's in German, but I think it's quite "selfexplanatory" :-D ).

WildBlue Satellite Services

As mentioned in the previous posts, O3b Networks will utilize Ka-Band. They are surely not the first who use that frequency band for commercial satellite services. Personally, I remembered "WildBlue" when I, for the first time, read about O3b Networks. Sure, if we look at the type of satellites they use and the services they offer, O3b and WildBlue are completely different. But I see they share the same idea: reinventing satellite technology for broadband purposes. Though, I'm a bit dissapointed to know that O3b can "only" achieve a bit more than 1 Gigs/beam or around 10 Gigs/satellite... :-D .. I did hope for a bigger figure :-D

Submarine Cable Repair/Maintenance

I'm preparing some videos for my class in this fall semester and searched for those in YouTube. Below is one video showing submarine cable repair/maintenance. It's almost similar to a video distributed by Alcatel-Lucent, except that it's 3D! Cool, right?
