EDAs require the combination of a mobile phone and a full functional computer. They integrate processing power, memory, Windows Mobile operating systems, wifi, bluetooth, internet, music/video, digital cameras, and sometimes GPS, bar code, RFID all working with email/calendar features connected over the Internet to enterprise corporate databases and software applications. The simple PDA has been transformed into an essential tool designed to extend the power of corporate database applications into the hands of the mobile workforce.
Think about it...nearly 40% of the global work force is mobile. That means they are traveling, driving delivery trucks, working in field services, repairing equipment at a customer's location, farming, building homes, etc. These mobile workers need access to corporate and customer data and the use of corporate software applications, yet they need them on a portable, ruggedized handheld computer that can fit on their belt or in their pocket.
