Open-AT marketing presentation

External application driving through the serial link Overview Software mechanism allowing a customer to embed a simple application into a Wavecom dual-band device* Embedded Application Wavecom Core Software External application driving the Wavecom device through the serial link * WISMO2C, WISMO2C-2 (GSM), WISMO3, WMOi3, WMOD2B

Targeted markets Potential users include integrators and application developers* in the field of:  TELEMETRY  AUTOMOTIVE  FIXED TELEPHONY  MULTIMEDIA * Candidates for the Open-AT must be experienced in C programming and AT commands

Interfaces External interfaces available on the target hardware for the embedded application (via AT commands): External modem: RS232 serial signals (only available in Open-AT release #2) Integrated modem: GPIOs keypad interface serial signals (only available in Open-AT release #2) SPI (LCD interface) (only available in Open-AT release #2) Module: buzzer  Open-AT is almost appropriate for the integrated modem and module

Possible applications TELEMETRY: Vending machines, utilities, alarm systems: Transmission of data/SMS on hardware event or on a regular basis for alerting or for monitoring purposes. Remote control of a system AUTOMOTIVE: Consumer or professional car equipments: Automatic and independent transmission of an SMS to a service center in case of emergency (crash, breakdown, theft,…). Remote control of the car (for security or comfort purposes)

Possible applications FIXED TELEPHONY: Wireless Local Loop phones, wireless public phones Simple MMI and call management. MULTIMEDIA: PDAs Decoding of proprietary commands sent by the computing device processor to activate GSM operations. The embedded processing reduces the load of the main processor. Autonomous processing of incoming GSM events. The main processor is awaken by the module only when necessary (to save battery).

Benefits For the targeted markets, Open-AT allows to independently: Detect/alert Count/monitor Decode/process Control Moreover, for these operations, the GSM unit can be remotely driven. Rmk: no delta approval shall be required to release an Open-AT based application (negociation to be done with ETS)

Benefits Customer benefits Using the Open-AT, integrators and application developers can: save external hardware (in case of simple applications): no need for additional microprocessor and memory  cost reduction (valuable for TELEMETRY, AUTOMOTIVE) use the GSM unit as a stand-alone emergency system  better efficiency (valuable for AUTOMOTIVE) quickly develop and test their application  quicker time to market (valuable for TELEMETRY) implement cooperation schemes between an external application and an embedded program  better efficiency (valuable for MULTIMEDIA) Wavecom benefits Open-AT is a Unique facility  differenciation Cost/Time efficient solution  customer acquisition Wavecom specific facility  customer loyalty

Product MIX: product Open-AT requires: a Wavecom dual band product (programmed with an Open-AT compatible FW release): not part of the Open-AT offer. Remarks: GSM / Open-AT require 16/2 Mb GSM-GPRS / Open-AT require 32/4 Mb  this configuration will not be proposed at the beginning The Open-AT product consists of: a SDK including documentation, examples, tools and support. It shall be available on CD-ROM+paper doc and packaged in a specific box (with specific cover). Milestones: End 03/01 (with FW version V420): 1st release not supporting the data service and the serial link management. Test version only (SDK not available): beta & pilot tests. 06/01: promotion 08/01 (with FW version V430): 2nd release supporting all the services + one additional interface (SPI I/F, to be confirmed). 1 month pilot tests before delivery. 09/01: official release.
