Dual-mode wireless communications module
The first LTE Cat NB2/GSM dual-mode wireless communication module BC97 from Quectel supports switchover between GSM and NB-IoT networks and ensures utilizing network coverage of both technologies.
The BC97 is designed in an ultra-compact 23.6mm × 19.9mm × 2.2mm form factor, and is compatible with Quectel’s GSM/GPRS M95 module, which allows smooth migration and minimizes cost and development time. In LCC+LGA form factor, BC97 can realize the rapid production of modules through a standard SMT machine.
The BC97 features low power consumption, extended operating temperature range, global dual-mode, and supports GSM Voice and Bluetooth Low Energy (BLE). Thanks to all-in-one features and a rich set of interfaces (such as USB, USIM, UART, ADC, RESET, PWRKEY, SPI, GPIO, Main Antenna, especially Audio Interface MIC and Speak) as well as the DFOTA, BC97 extends its coverage to multiple applications such as Shared Bikes, Smart Parking, Bluetooth Gateways, Smart Metering, Smart City, Asset Tracking, Smart Home Appliances, Wearable Devices as well as Agricultural and Environmental Monitoring Devices, to name a few.
“It is an irreversible trend for GSM to migrate to LTE and 5G network. Nevertheless, with extensive global network presence and its vast coverage, it is foreseen that GSM network will still be operational for many years, especially in certain developing countries. Since BC97 supports fallback from Cat NB2 to GSM, it can utilize the existing yet matured GSM network, hence would be gradually and seamlessly migrating into NB-IoT network,” said Ottmar Flach, General Manager Atlantik Elektronik GmbH.
