Description
The EVLKST8500GH-2 hybrid connectivity solution for the ST8500 SoC platform
combines the advantages of both PLC and RF technologies to enable applications
with the best coverage in any network conditions and topologies.
The user can easily explore features and benefits of the STMicroelectronic's hybrid
PLC&RF solution using the EVLKST8500GH-2 kit together with the STSWST8500GH-2 firmware and documentation package.
Messages between two nodes in the PLC&RF hybrid network are sent over the best
available medium: PLC or RF. The media selection for each link in the network isdone automatically and adjusted dynamically, enabling highly efficient hybrid meshnetworking.
The STMicroelectronic's hybrid PLC&RF solution is based on open standards andenables seamless integration into existing G3-PLC networks and adoption in multiple
applications and systems.
Note that at least two EVLKST8500GH-2 kits must be ordered to test hybrid PLC&RF
connectivity between two nodes.
