Standard version of Wirnet iBTS
The following figure describes the functional architecture for the standard Wirnet iBTS
version i.e. including from one to three “LoRa Modules”:
Figure 13: Standard Wirnet iBTS block diagram
The RF front-end board of the “Lora modules” can be derived in 3 bands versions to address
different countries:
o
868MHz (863-873MHz)
o
915MHz (902-928MHz)
o
923MHz (915-928MHz)
The RF front-end board is configured to support a single antenna (16 channels) or two
antennas (2x8 channels). This could lead then to a “six LoRa antennas” configurations in the
maximum use case (tri-sectors, dual polarization antenna for instance).
The GPS (GNSS) connector, the WAN (LTE) connector and LoRa connectors are available on
the bottom side of the enclosure. All antennas are external antennas.
