BG77xA-GL is a 5G-ready ultra-compact LPWA module compliant with 3GPP E-UTRA Release 13/14 specification. The module supports LTE Cat M1 and LTE Cat NB1/NB2 bands and integrated SIM (iSIM). Besides, it features ultra-low power consumption implemented by MIPS 5150 processor and integrated RAM and flash, which help reduce current consumption to rather low levels in various modes, including PSM, eDRX etc. It is further integrated with a GNSS engine that supports GPS and GLONASS systems and a cellular-based positioning engine that supports QuecLocator®.
BG77xA-GL comes in three variants: BG770A-GL, BG772A-GL and BG773A-GL.
BG77xA-GL boasts a comprehensive hardware-based security feature - Integrated Security Elements (ISE). With an ultra-compact SMT form factor of 14.9 mm × 12.9 mm × 1.9 mm and a high integration level, the module enables integrators and developers to design applications easily leveraging its low power consumption and compact structure design. The BG77xA-GL’s advanced LGA package allows for fully automated manufacturing required for large-scale applications.
A rich set of Internet protocols, industry-standard interfaces and abundant functionalities extend the applicability of the module to a wide range of M2M applications, such as wireless POS, smart metering, tracking, wearable devices, and many more.
