Microsoft will launch its Pocket PC 2003 operating system on 23 June, and Gateway and Hewlett-Packard (HP) will announce their latest PDAs.
The latest version of Pocket PC will come with improved capabilities for detecting and maintaining wireless network connections, and better performance. It will also be optimised for Intel's XScale processors.
Gateway will make its debut into the handheld market alongside the Pocket PC 2003 launch. The company has embarked upon a strategy to turn its fortunes around by emphasising consumer electronics products in addition to its flagship PCs.
HP will release iPaq models in its h1900 series. The iPaqs will come with processors from Samsung Electronics based on a core developed by ARM.
The h1940 and h1945 models will come with Bluetooth, the short-range wireless networking technology, and all models will feature a Secure Digital I/O slot.
HP is also expected to release the h2200 series of iPaqs, and two h5000 series models. Those PDAs will come with XScale processors from Intel.
