Mobile operators have started shutting down 2G networks to free up frequency bands for the newer 4G and 5G communication signals. Module manufacturers have, therefore, made their 2G modules end-of-life and are now moving their low-cost 4G modules to Cat 1 bis only and doing away with the 2G Fallback.
The SIMCom strategy is no different, and the company has released the A7673X series, a Cat 1 bis module based on the ASR1606 chipset. The module supports LTE-FDD, with a maximum downlink rate of 10 Mbps, and an uplink rate of 5 Mbps.
The A7673X series adopts the LCC+LGA formfactor and is AT command compatible with the A7670 R2 series, the SIM7000/SIM7070 series, and the SIM800/SIM800F series.
This enables smooth migration from 2G/NB/CATM products to LTE Cat 1 products, and facilitates more compatible product design for customer needs.
The modules feature interfaces for expandability such as UART, USB, I2C, and GPIO, making them suitable for IoT applications such telematics, metering, surveillance devices, and industrial routers.
