There are literally hundreds of mounts or docks for tablets to suit any application. We recommend the Rammount solutions, www.rammount.com for SmartBridge tablet mounts. eBay and other online stores have many options. You do not need a powered docking station. The cables provided will deliver power and data.
No problem. We own the whole solution stack so are happy to discuss how we can make this work best for you. Depending on the requirements we will charge an hourly rate for scoping, and then quote either an estimate or fixed price for the complete work including testing. Our rates are consistent with other software development rates, and of course we know radio!
