Wired & Wireless System Development

near-field wireless system

Products designed by Stilwell Baker incorporate a wide variety of wired and wireless communication interfaces, ranging from communication between chips on a board, board-to-board serial protocols, connection of devices to or as standard peripherals, and wireless protocols for remote machine-to-machine (M2M) communication. We select interfaces based on requirements for latency, bandwidth, signaling rates, pin count, density, electrical isolation, code size, availability of peripherals, availability of drivers, interoperability, standards compliance, and security.
