L GSM phase 2 / 2+ l GPRS Class 10; Sensitivity <-107; Support voice calls; Support SMS text messages; Support mobile and Unicom 2G, and the global GSM network GPRS data characteristics, the maximum data rate, download 85.6Kbps, upload 42.8Kbps; Supports serial port multiplexing with GSM 07.10 protocol Support two serial ports, a download serial port, an AT command port; AT commands support standard AT and TCP / IP command interfaces; Support for digital audio and analog audio, support HR, FR, EFR, AMR voice coding; Support FCC, CE certification; SMT 42PIN package; ————— Advantages of GA6 Module ———- Wide area coverage: GPRS in the country 34 provinces are well covered, it is the world’s leading 2G communication standards. Basically in the phone can call the place can be through GPRS wireless Internet access; Always online: as long as the activation of GPRS applications, will remain online, similar to the wireless line network services. Charging: GPRS service is always on the line, but you do not have to worry about the cost problem; because only when the traffic generated traffic billing. High-speed transmission: the current GPRS can support 85.6Kbps peak transmission rate, the theoretical peak transmission of up to 100 Kbps. Inexpensive: Compared to the SIM series, the price of the module is only half of it. Greatly reduced Entry threshold of Internet of Things equipment; GA6 is an ideal solution for M2M applications for automotive, industrial and PDA, personal tracking, power environment inspection, wireless POS, smart metering and other M2M applications with ultra-small size, ultra-low power and wide operating temperature range , To provide a perfect GSM / GPRS SMS, data transmission and voice services.
