Wavecom’s (NASDAQ:WVCM) WiSIM is a solution that facilitates the deployment of industrial wireless devices in cellular networks. WiSIM, which is short for Wavecom integrated Subscriber Identity Module, addresses the requirements for industrial wireless devices. These requirments include: long-life — more than ten years for utility meters, for example — and harsh environments such as extreme temperatures and excessive vibrations for vehicles. The typical SIM card, like those used in GSM mobile phones and other consumer electronics are built in to plastic cards and therefore do not address the rigorous demands for many industrial applications.
The WiSIM component will be an embedded option in selected Wavecom GSM/GPRS Wireless CPU(R) families including Quik, Plug & Play and its Wireless Microprocessor(R) range. By integrating the SIM at the chip level, both customers and operators benefit from a simplified and faster cellular subscription. The robust industrial design ensures proper functioning in harsh climatic conditions which reduces the risk of disconnected devices that are often linked to high-value, time-sensitive transactional data. In addition, with the SIM embedded into the Wavecom Wireless CPU(R), logistics and management issues associated with the SIM card inventory becomes easier, more cost effective and more secure, thus reducing the risk of potential SIM card theft, especially once it is installed.
