HSDPA Cellular Module
The U5501 is a Dual-Band HSDPA/WCDMA and Quad-Band EDGE/GPRS/GSM module solution which supports HSDPA 3.6Mbps for data transfer. In areas where HSDPA is not available, it still enable reliable and secure data connection over UMTS at speed up to 384 Kbps or EDGE at speed up to 237 Kbps or GPRS at speed up to 85.6 Kbps.
Except used as a standard wireless modem through AT command, U5501 offers Audio, SMS, MMS, Phonebook.
