    Thin Clients and wireless

    I am looking to use Thin Client technology on our wireless mobile classrooms as a way to better use the available bandwidth in our school. With many wireless access points only allowing a small number of logings concurrently even though they state 30+ concurrent connections this is a problem I'm hoping to overcome with the thin client technology available. However as wireless is a little flaky we'll need to check that our chipsets will be supported by the thin client OS we choose has anyone thought about doing this?

    we had problems implemeting wireless thin client as the ip address wasn't given until drivers had loaded (i think) i binned it the end.

    How would a thin client solution help with your bandwidth over fat clients? surely x amount of thin clients getting everything they need over the wireless as apposed to x amount of fat clients on getting docs etc... would be worse?

    Yes, that's what I was wondering. Thin clients are in constant communication with the server(s) where as fat clients will only go to the network when they need a document/web page/etc.

    Sorry haven't really explained we have wired fat clients but there is to be an influx of mobile labs and I don't believe the current wireless system is good enough to handle the amount of traffic without being made into thin clients.

    Re: Thin Clients and wireless

    Yes but the amount of data sent over a thin client connection would be relatively small?

    Re: Thin Clients and wireless

    Also the main issue has been the time for the logins we have only managed to get 8 clients to login simultaneously whereas with thin clients this should not be a problem. Even without the roaming profiles et cetera it still throws one when you try to concurrently login more than 8 per WAP device so I thought I'd add some 1gb wireless cisco wap put in the thin client system and hopefully this would sort it out.

    Re: Thin Clients and wireless

    Citrix uses about 20kb/s and any network problems will be exacerbated on a TC network.
    Personally I'd wire the classrooms, whilst it might be technically feasible to do this over wireless it will ultimately be a PITA.
    Wireless is designed to support a wired infrastructure not replace it.

    I'm sorry but I don't think what you are trying to do is going to improve your experience of wireless I can only see it becoming worse a well desinged and managed wireless network will support more than 8 concurrent users.

    Yeah the load balancing and other options have to be re-configured I think looks like its back to the drawing board. Oh well!

    Re: Thin Clients and wireless

    I do exactly this... 30 laptops set up with a simple icon on a Windows XP desktop to log onto the Citrix farm.

    The bandwidth used for thin client communications is negligable compared to the bandwidth used to log on, download a profile, open up a document, etc.

    I auto-logon the notebooks after a pre-logon connection to the wifi network purely for printer management and the like but you don't even need to do that.

    Another option is to buy purpose-built devices such as the Neoware m100 thin client notebook ( http://www.neoware.com/mobility/index.html ).

    Re: Thin Clients and wireless

    Can this be used with things like Precedence ThinIT client? How does it stand up to use from say MS Publisher Ric_?

    Re: Thin Clients and wireless

    As long as you get a basic 'shell' OS operational that is capable of running your ICA or TS client and has the wireless drivers loaded, you should be fine.

    I have only ever used Windows as the client OS on the laptops... because the laptops came with Windows licenses and I needed to be able to run the Data Harvest data logging software locally on the machines.

    As for running Publisher, it runs fine... it's running on a dirty great big terminal server elsewhere in the school after all. Ass to why you would want to run Publisher in the first place... now that's a different question!

    The only way that I can see you having a problem is if your wifi is prone to interference and drops out, rather than a lack of bandwidth. The ICA or TS client should reconnect your session though and ICA uses session reliability to try to prevent this anyway.
