Router Security Vulnerabilities Could Compromise the IoT

On February 20, 2019 in All, IoT, Lighting, RF, Security, Sensors, Wireless by Steven Keeping

Wi-Fi routers offer a cheap, convenient gateway to connect IoT sensors to the Cloud, but tests reveal the devices have weak security. As the IoT grows, they could prove even more enticing targets for hackers. New developments bring more protection, but other technologies could prove a better option.

Connected-Home Tech Falls Short but the Future is Bright

On January 24, 2019 in All, IoT, Lighting, RF, Sensors, Wireless by Steven Keeping

While smart-home devices are gaining traction, the truly connected home remains a dream. Engineers are working on interim solutions to meld disparate wireless technologies, with some success, but a single smart-home solution is far in the future.
