Product Concept
2.1. General Description
BG770A-GL is an embedded IoT (LTE Cat M1, LTE Cat NB1/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*
The module is based on an architecture in which WWAN (LTE) and GNSS Rx chains share certain
hardware blocks. However, the module does not support concurrent operation of WWAN and GNSS. The
solution adopted in the module is a form of coarse time-division multiplexing (TDM) between WWAN and
GNSS Rx chains. Given the relaxed latency requirements of most LPWA applications, time-division
sharing of resources can be made largely transparent to applications. For more details, see
document [1].
