Moduł SIM508 GSM/GPRS+GPS

Wprowadziliśmy do ofery moduł GSM/GPRS + GPS model : SIM508. Jest to trzy zakresowy (900/1800/1900 Mhz) zintegrowany moduł GSM/GPRS z systemem GPS do nawigacji satelitarnej.

Dzięki zintegrowanej funkcjonalności GPS po zastosowaniu modułu SIM508 w dokładnie możemy ustalić jego położenie.
