On the back of the production release of the Meerkat 2G, Otto Wireless Solutions has announced the release of its custom developed Meerkat 3G modem for March 2014.
During late 2013, Meerkat 2G prototypes were deployed to a selection of beta customers and, based on positive feedback, the company decided to fast-track the release of the 3G variant. The first production run of the Meerkat 2G, which commenced this month, also included the first 10 3G devices.
The Meerkat family is designed as a two-tier printed circuit board, with the top one being the carrier board for the GSM engine, making replacing the 2G board with a 3G board a fairly simple and seamless process.
Aside from the increased speed, the performance and features of the 2G and 3G models are identical, in that both devices are capable of opening, monitoring and maintaining TCP connections on startup, and both have two SIM card interfaces between which they can switch seamlessly in the case of poor signal. The Meerkat’s graphic interface allows users the ability to reconfigure either of the devices, or create a configuration file which can then be stored for later use.
Internally, the devices house a pre-loaded 1 GB Micro-SD memory card, which is accessible as a standard USB storage medium. The same powerful ARM core controls both the 2G and 3G models, the firmware for which can be changed by simply placing a new file onto the Micro-SD card and cycling the power of the modem; the bootloader does the rest.
External interface to the modem is via either serial or USB port, and a wide input voltage range of 12 to 60 V d.c. is accommodated. There are eight I/O interfaces available for developers who have the appropriate software suite which will allow them to customise the ARM core to their own requirements.
In due course, Otto Wireless Solutions intends to launch a forum for developers who will be certified to program the core and customise the product and I/O based on end customer requirements.
