You should start by defining one or two key applications that would provide strong ROI when they become untethered. Completely transforming your core e-business functions for wireless access could be a pricey affair -- prepare to put an estimated $50,000 (or more) dent in your budget for a complete transformation.
The AS/400 has completed its shift from legacy system to excellent e-business solution. Enabling wireless access to AS/400 applications and data is now just as viable as with any competing e-business server platform. You can choose to enable wireless connectivity on your company's AS/400 via e-mail, WAP, or ASP (application service provider).
No matter the method you choose, the AS/400 will bring e-business applications and data to end-users, customers, and business partners regardless of their location or their mobile device.
