XT55/56

The XT55/56 is the first tracking module to combine Tri-Band GSM/GPRS and GPS technologies on a single PCB smaller than the size
of a matchbox. As these technologies work seamlessly with each other, the module opens a new dimension for applications within
the tracking and tracing market.
There are two variants of this GPRS Class 10 Tri-Band module – the XT55 and the XT56. These cover the entire spectrum of GSM networks,
which means they can be used globally. Due to their exceptionally compact design, these wireless modules can be easily incorporated
in M2M applications. The intelligent, energy-saving TricklePowerTM Mode is one of several power saving methods which guarantee a
long battery life within your application.
Thanks to its reliability, small size, worldwide utilization, and the smooth interplay of GPS and GSM communications, the XT55/56
provides ideally for security solutions, locating people and vehicles, and is equally well-suited for applications in transportation and
logistics.
As it also has full type approval (FTA), there’s nothing stopping you now from producing a successful product – the XT55/56 has been
approved by major network carriers around the world, including the US operators.
