RF Solutions GSM & GPRS Modem

T61 is a smart gateway to connect serial devices with RS232 or RS485 interfaces to GSM/GPRS/HSPA network. T61 could also function as a normal 2G or 3G modem to accept AT commands. It is a device that integrated with a 32bit ARM Cortex-M0+ core processor and Gemalto BGS2 (2G) or EHS5 (3G) modem modules. It can operate in server or client mode, accept SIM card with dynamic IP or static IP, supports TCP/UDP, schedule to connect, connect on demand or "always on" connection, and with Auto Recovery, Re-connection and Redundancy mechanisms. It is designed for mission critical applications. As compare to PSTN or GSM dial up line or lease line, the T61 with GPRS or 3G communication link provides a cost economical approach to achieve "always ON" packetized data network. It is a plug and play device, allow you to migrate from traditional serial communication system to the advance GPRS or 3G link, without tedious application development and in depth knowledge of AT command or GPRS. You can view this device as the "virtual serial wire over the air", that links all your remote equipment to the central PC. It can be a full transparent, protocol independent gateway, used for AMR, SCADA, general remote monitoring, control and data exchange applications.
