Sammanfattning
Equipment for testing the 4G and GPS functionality in a cellular modem can be expensive for a small company. This master’s thesis investigates how a simple testbed
can be implemented in an affordable way. The investigation concluded that a software defined radio together with open-source software could be used for a low-cost
testbed implementation. The proposed solution was implemented and the testing
of the system showed that it indeed can be used for functional verification of 4G
as the testing is quick, stable, and successfully simulates a realistic scenario. The
implemented GPS test is stable and can successfully be used for functional verification, but cannot simulate a realistic worst-case scenario in terms of signal power.
The main conclusion is that a software defined radio indeed can be used for simple
testing of LTE and GPS functionality in a cellular modem.
