Eliminate mobile phone recalls, ensure reliability, and enhance customer satisfaction using Red Bend's vRapid Mobile FOTA (firmware over-the-air) update solution. vRapid Mobile FOTA dramatically shrinks update file size and overcomes barriers to reliable and cost-effective updating of firmware on mobile phones already in the hands of users.

vRapid Mobile FOTA Handset Update Suite

vRapid Mobile FOTA enables mobile phone manufacturers and carriers to create compact firmware updates for mobile phone handsets and to install the updates over the air rapidly and with complete reliability.

Based on Red Bend's patented technology, vRapid Mobile FOTA is composed of two primary components: an update generator and an update installer.

vRapid Mobile FOTA's Update Generator identifies the essential changes from an existing firmware version to a new, updated version and automatically creates an extremely compact package of these changes. The Update Generator also supports updating a handset's fi le system, which typically stores images, sounds, configuration information, settings, design themes, icons, menus, system status and other information that affects device appearance, configuration and branding.

vRapid Mobile FOTA's Update Installer resides on the mobile handset itself and performs the update installation. Optimized for the limited memory available within the handset, the vRapid Mobile FOTA Update Installer applies the updates in-place on the phone's firmware accurately and reliably. It performs this update on feature phones with monolithic firmware images and on smart-phones with compressed, multi-section images. The update installer also performs file system updates.

vRapid Mobile FOTA Advantages

Proven and patented Red Bend delta-update technology overcomes bandwidth and memory constraints. Red Bend's patented delta-update technology extracts only the essential changes between mobile phone firmware versions, reducing update file size by up to 97% and lowering device memory and bandwidth requirements, while maintaining

vRapid Mobile FOTA supports advanced phone architectures. Using advanced algorithms, vRapid Mobile FOTA supports Symbian OS and other architectures that employ compressed multi-section images, read-only file systems, a combination of NAND and NOR flash and other advanced features.

vRapid Mobile FOTA speeds up flash reprogramming. By updating only the changed sectors of the firmware image, vRapid Mobile FOTA signifi cantly reduces the time the handset is out of service for updating and minimizes the user's inconvenience. vRapid Mobile FOTA's patented computational update technology can guarantee consistent update performance for an unlimited number of on-device updates, from any firmware version to any other version.

vRapid Mobile FOTA optimizes on-device memory. Using a unique "in place update" algorithm, vRapid Mobile FOTA requires only minimal working memory to perform updates while providing control over the amount of flash memory required. This patented technology resolves complex "write before read" issues so that firmware can be updated rapidly without adding costly memory.

vRapid Mobile FOTA can be integrated into handset firmware in a matter of days. vRapid Mobile FOTA's unique technology and QuickPort™ process allow handset manufacturers to integrate the firmware update technology without restructuring device firmware and with no impact on the firmware development tool chain. As a result, integration has been proven to be significantly faster and less expensive than alternative solutions.

vRapid Mobile FOTA ensures 100% fault-tolerant update integrity and completion. vRapid Mobile FOTA eliminates the risk of disabling devices due to errors or unexpected disruptions in the update process. In the event of a power loss, it automatically resumes the update from the point of interruption.

vRapid Mobile FOTA ensures security for all stages of the update process. Using a patented pre-installation verification technique, vRapid Mobile FOTA software verifies that the newly created software version is 100% accurate, bug-free and will install properly, prior to the update process getting under way.

vRapid Mobile FOTA operates with other mobile device management solutions. vRapid Mobile FOTA works with all existing mobile device data distribution and transfer solutions and all standard protocols.

vRapid Mobile FOTA Update Installer minimizes the on-device footprint. The Update Installer software requires only one fl ash sector of 64KB as permanent allocation for the Update Installer (about 20KB) and the device specific Update Agent, and one to be temporarily allocated upon running for the update specific data, to ensure start-to-finish integrity of the update install process.

vRapid Mobile FOTA Update Installer is update-able over the entire device lifecycle. The Update Installer software itself can be quickly updated over the air, allowing it to be embedded during the manufacturing process and upgraded remotely and transparently, as required, throughout the life of the device.
