TC20 without wifi router


First, sorry for my very bad english !


I want to buy two tc20, but we don't have a global wifi router.


I want to save in the tc20 all our modify in our storage space. Then, we go back to the computer to transfer all data.


I don't know what is the best method to transfer this data. I want connect the TC20 with USB cable, but android maybe need to be in developer mod to transfer data.


I also want to use the tc20 like a barcode reader (datawedge ?).


I think, it's possible to create a hotspot wifi with a program like MyPublicWifi, maybe Zebra have the same program ?


I develop the android application and the windows application. (I can change all on this program).


Do you have a better solution for my use ?


Thank for your advice !
