1. Introduction
1.1 Description
The GT47/GT48 is an intelligent GSM/GPRS control terminal that
encapsulates everything you need for wireless M2M capability in one
compact unit. In conjunction with Sony Ericsson’s M2mpower package the
GT47/48 can host and control your wireless application, minimising the
need for extra components. Alternatively, it can be used as a powerful
standalone GPRS modem with its intrinsic TCP/IP stack.
The GT47/48 is a self contained terminal with its own SIM card reader and
standard connector interface, minimising the need for further hardware
development.Its wide and useful range of IOs can be reconfigured to add
functions and features that make your M2M solution both innovative and
cost effective.
The GT47/GT48 can be used to provide a communications link for a
variety of wireless applications including fleet and asset management,
vending, security and alarm monitoring, e-maintenance and other
telemetry applications. The ease of application development and hosting
on the GT47/48 means M2M solutions in area of personal leisure (e.g.boats
and caravans) and around the home can be addressed.
With dual band 900/1800 MHz (GT47) and 850/1900 MHz (GT48)
versions available, your applications can be used all over the world.
The control terminal comes with a library of sample script applications to
