The cards are for linking wirelessly to a mobile phone network, either gprs or 3G. they also contain wifi technology. you can use vpn, remote desktop etc through them just as if they were a normal internet connection.

>>Hi Dmitry,
>>we have tried a couple of different appraoches.
>>firstly we tried using 3G data cards that fit into the pcmcia slot, but although they are fast enough we had problems with coverage in small towns in ireland, the tablet is for reps who are on the road. I have to say that we have one for our own testing purposes etc in our office and i sometimes use it at home if a customer calls me after hours and i find it great, i don't have a home phone and use a mobile for everything so i can't get broadband line at home.
>>what we went with in the end is a using the data cards but only infrequently, from once a day to once a week. The user opens a small app that takes his/her transactions and zips them up. then sends them to an ftp server. they can check for updates to the program and download then if necessary. a seperate program on the server creates a new update file every night at 4.30 containing updated information that the reps on the road may need. also it takes in the file that are there are imports the data.

>>>Has anybody successfully developed VFP apps for Tablet PC? If you are using them to "collect" data and then need to update database (VFP) residing on a file server, how do you do it? In a batch method, as Pocket PC? or via wireless connection?
