Back at CES 2011, Samsung showed us something that may have seemed a bit futuristic back then but which is now reality. They showed us a monitor that connects to your laptop wirelessly and on top of that, the monitor acts as a USB hub and the USB devices connect wirelessly too. Samsung calls this technology Central Station. You simply connect a small USB dongle to your laptop, take the laptop within the monitor’s range and your laptop automatically connects to the monitor and peripherals attached to it, wirelessly. You walk away and the monitor goes black. Pretty simple, right?


During the last few years, laptops have become powerful enough for people to use as their main computer. Sales figures support this too. If we look at for example Apple’s sales figures, twice as many desktops were sold compared to laptops in 2002. However, during the recent years, laptops have stolen a huge portion of the sales of desktops, making the situation the opposite of 2002: laptops now outsell desktops by a two-to-one ratio.

While laptops can now offer performance sufficient for some real work, there is one thing that they cannot offer: screen real estate. Most laptops have around a 15” screen, but resolutions vary a lot depending on the model and price range (1366x768 at the low-end, and up to 1920x1200 in higher-end models). 22-24” monitors with resolutions of 1920x1080 have more or less become the standard for desktops and such monitors can be had for ~150$ nowadays.

Because laptops lack screen real estate, a laptop with a separate monitor at home has become a very common setup. This gives you portability when on the go and a desktop-like setup when at home with extra screen size/resolution. However, this kind of setup has one big setback in that you need to plug in a bunch of cables when you get home to use your external monitor and other peripherals. With a desktop, you just turn the computer on or wake it up from the sleep mode; there's no hassling with cables required. While you could call one lazy if it’s too much to plug in a few cables, you often end up either using the laptop on the desk with the monitor all the time, or you never plug in the monitor and it sits on the desk unused.

Laptop docking stations have offered a solution, but there are several shortcomings. First off, not all laptops have a design suitable for docking (Apple’s laptops come to my mind). Second, each laptop dock is only suitable for certain laptop models, so if you buy a new laptop you most likely have to buy a new laptop dock as well. A new dock will easily set you back at least $100, which is quite a lot for an ugly piece of plastic. Finally, many consumer laptops don't even have suitable docks, which rules out a docking station completely. 

This is where Central Station becomes interesting. You don't need to connect any cables and you don't need an ugly dock. Everything is wireless.

    It's apparently using a proprietary wireless connection, which would limit it to the handful of laptops supporting in; just like current docking stations are limited to the handful of laptops using their dock connector.

    If it used Intels wireless display tech I could potentially see the point, although at least initially the same problems would be present there's a reasonablish chance if it becoming common in the next few years.

    Uh... because it sounds like the USB dongle handles all the communications, so it would work with pretty much any laptop.
  • Kristian Vättö - Wednesday, June 15, 2011 - link

    Yes, that is the idea. Any laptop with appropriate specs (see the System Requirements) should be able to use Central Station.

    I missed the bit about the dongle. The question becomes how big is it? Leaving the traditional thumbdrive sized ones is dangerous since they're easily bashed while moving the laptop. Unless it's the very small plug sort you'd just change having to plug a cable for having to plug a dongle in every time you went back to your desk.

    Simple video cable standards are gaining sub channels large enough to do most of what you need for other accessories. HDMI can carry 100MB ethernet on a subchannel, DP1.2 has a 720Mb/sec sub channel which is enough headroom to carry USB2 as well.

    There are two good pictures (Anand doesn't like to use other people's pictures so I left them out. Besides, there is nothing on Samsung's site so could be that these connectors are not the final ones).

    I suppose folding up is less of a problem than sticking out, but it's still probably not something I'd be comfortable with leaving on my laptop 24/7. Especially since with intel pushing to make ultra thin laptops the default that's going to end up well over the top with the lid closed. Maybe it if could rotate 90* and run parallel to the laptop body, although you'd be dependent on the plug layout letting you do that without blocking anything important.

    How does USB have enough bandwidth to drive a 1080p monitor (along with all the other docked features like keyboard, mouse, etc)
