Dear sirs. I have a question about the signal Quality and GL7600. We have another modem from another brand and when I send AT+CSQ i receive +CSQ: 19,99. So i have GL7600. I send exactly the same AT command (AT+CSQ). The modem are 20 cm from the other modem. Now i receive CSQ: 7,4. Why are this data only 7. It is the same band (4G) and the antenna is the same. Best regards Bjarne ---
