Internet-Connected Smart Products
Barr Group is in the business of designing reliable and secure computers and we have software engineers with hands-on experience designing a wide variety of mass-market Internet-connected products that network via 802.11 WiFi, RFID, NFC, Bluetooth (including BLE), Zigbee, cellular, and M2M. For example:
- Smart TVs and smart speakers from Google, Amazon, and Apple
- Set-top boxes for cable and satellite television
- Wearable computers such as fitness trackers and heart-rate monitors
- Smart home thermostats, doorbells, sensors, and LED light bulbs
- Network LAN/WAN routers, hubs, and switches
- Edge computing devices and routers for cloud computing
- Embedded systems and embedded software ("firmware")
Barr Group's engineers are familiar with all of the major technologies used to design connected devices including the Google Cloud IoT, Amazon AWS IoT Core, and Microsoft Azure IoT frameworks, Linux and real-time (RTOS) operating systems, and also the programming languages that are used, such as assembly, C, and C++. And we are equally comfortable reviewing electronic circuits and schematic drawings.
