Product Description

BG77 is an embedded IoT (LTE Cat M1, LTE Cat NB2) wireless communication module. It provides data connectivity on LTE-FDD network, and supports half-duplex operation in LTE network. It also provides optional GNSS and voice* 1) functionality to meet customers’ specific application demands.

With a compact profile of 14.9 mm ×12.9 mm ×1.7 mm, BG77 can meet almost all requirements for M2M applications such as smart metering, tracking system, security, wireless POS, etc. It is especially suitable for size and weight sensitive applications such as smart watch and other wearable devices.

BG77 is an SMD type module which can be embedded into applications through its 94 LGA pads. It supports internet service protocols like TCP, UDP and PPP. Extended AT commands have been developed for customers to use these internet service protocols easily.
