Introduction

The compact EHS8 module offers the latest Java ME 3.2 client runtime platform optimized for resource-constrained M2M applications. It significantly reduces total cost of ownership (TCO) and development timelines by sharing internal resources such as memory, a large existing code base and proven software building blocks. The improved Java concept uses Multi MIDlet Java execution to simultaneously host and run multiple applications and protocols. An extended security concept with the latest TLS/SSL engine provides secure and reliable TCP/IP connectivity while an enriched internal flash file system enables free of charge firmware updates over-the-air (FOTA) when required. Sophisticated sandbox modeling and layered architectures simplify device management (DM) and separate mobile network operator approvals from application code development, allowing simultaneous progress of both phases for a shorter time to market. Providing the capability for multiple designs from one solution, the newest addition to Thales’s Industrial platform is an ideal module for applications migrating from 2G to 3G requiring cost efficiency along with global connectivity. EHS8 offers five band HSPA to support high bandwidth connectivity and enables speeds up to 7.2 Mbps in downlink and 5.7 Mbps in uplink. EHS8 supports common industrial interfaces such as USB, serial interfaces, I²C and various GPIO’s to be connected with the Java engine. Bringing together embedded GPS, a miniaturized footprint and cost efficiency with Java flexibility and 3G capabilities, the EHS8 module is the ideal solution for size-constrained applications such as track and trace solutions.
