Wavecom WISMO Cellular Modems
Wavecom rolled out their the WISMO (WIreless Standard MOdem) family of entry level GSM/GPRS modems for machine-to-machine (M2M) applications. The chips provide wireless voice and data connectivity in a highly compact form factor and at a very competitive price, without compromising M2M industry specific requirements. Customer sampling will start in March, followed by commercial availability commencing in May 2009. The price of the WISMO includes essential Intellectual Property Rights (IPR) coverage for the GSM/GPRS standards.
Unlike most entry-level solutions currently available on the market, the WISMO modem benefits from world-class manufacturing quality and delivery performance. The WISMO is produced on an ISO TS 16949 (automotive standard) certified manufacturing site, and benefits from all the inspection equipment already in place for automotive-grade products. Regarding deliveries, 95% of shipments from the factory arrive within 4 weeks from the order date and the on-time delivery rate is close to 100%, equating to significant logistics benefits for customers operating efficient JIT (Just In Time) manufacturing processes.
The first product in the new WISMO family, the WISMO 218, supports multi-bearer (GSM, CSD, SMS, FAX, GPRS) and multi-codec (HR, FR, EFR, AMR), is postage stamp sized at just 25mm x 25mm x 2.8mm, and is easily placed inside the customer product via either manual or common automated machine placement soldering methods. Castellation was selected for the first product in the new family as it is perfectly matched for a modem with an inherently low number of connection points and offers significant advantages over the more complex to use LGA mounting mechanism.
