LENA-R8 series modules include 2 variants:
•
The LENA-R8001 modules, integrating a cellular system supporting multi-band LTE Cat 1bis and
2G radio access technologies for global deployments
•
The LENA-R8001M10 modules, integrating the same multi-band LTE Cat 1bis and 2G cellular
system of LENA-R8001 modules plus a GNSS system based on the ultra-low-power u-blox M10
standard precision concurrent GNSS receiver. As illustrated in
, the cellullar and the GNSS
are independent subsystems of the module, internally interconnected by dedicated I2C interface,
with separate supply inputs and separate accessible interfaces for greatflexibility of use.
The modules provide Voice over LTE (VoLTE)

and Circuit-Switched-Fall-Back (CSFB) audio capability.
