MORE HANDSET DESIGNERS ARE CHOOSING JAVA because of its portability, security, and ability to optimize resource utilization. Esmertec's µ@PoC Push-To-Talk over Cellular Client for 2.5G and 3G mobile devices is just one aspect of this adoption.
The client brings walkie-talkie-style communication to mobile devices. It complies with the Open Mobile Alliance (OMA) PoC specification. (OMA strives to deliver open technical specifications designed to support mobile operators, devices, and network suppliers.) The key features of µ@PoC include easy group creation, grouptalk organization, fast retrieval of contacts from the phonebook, and access to participants' availability.
The client is built on Esmertec's Jbed Advanced multitasking Java virtual machine (JVM). The multitasking JVM is compatible with the Java 2 Platform, Micro Edition (J2ME). It supports the Connected Limited Device Configuration (CLDC), the Mobile Information Device Profile (MIDP), and the Java Application Management System (AMS).
A multitasking JVM lets network operators download and immediately use bug fixes, new applications, and new services. The JVM also provides real-time processing support.
