Fanny, You have made the point several times that multi-path is required for MIMO to work. While I agree that overcoming the problems that multi-path causes is one of the strengths of MIMO, I don't understand multi-path being a requirement. Two transmitters at one place, connected to two separate receivers at another, each pair using a separate multi-path free RF path will provide twice the throughput of one alone. By extension, any symmetrical MIMO (2x2, 3x3, 4x4). For a single receiver receiving packets from two transmitters (non-symmetric MIMO, 3x2, 3x4, etc., and cross channel paths) the packets have to arrive at slightly different times, either caused by different RF path lengths (multi-path) or by delaying one of the transmitters. Perhaps the distinction should be made between multi-path and multiple RF paths.
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
