Four band GSM GPRS SM5100B-D DTU Series Module


The SM5100 series is a GSM/GPRS wireless communication module specifically designed for wireless fixed phone and data transmission devices. The module integrates protocol and application layer software, developed independently by Spreadtrum, into our highly integrated baseband chip. With this unique approach, the SM5100 enables a base platform for customers that is smaller in size, stable, and easy to develop. The SM5100 series module is approved by China, North American and European standards, such as FTA, FCC, PTCRB and GCF.
