Low-Density Parity-Check (LDPC) codes are finding increasing use in communications applications. Find out how they work and how an understanding of modern forward error correction techniques is essential to the implementation of current and future communications technologies.
Have you ever wanted to turn your lights on/off using either a physical switch running Zigbee or by a BLE application on a smartphone? Read more to discover how you can build a device to do precisely that.
Exploring Silicon Lab’s BLE/Zigbee multiprotocol implementation using their development kit based on EFR32xG21 SoCs, this post details how the protocol reduces the hardware cost as you only need one radio to support two protocols.
In this blog, we describe how to set up and work with a LoRa GPS-tracker node device. These devices, among other functions, typically keep track of their location via GPS and send their data through gateways onto the LoRaWAN network.
In this blog, we document the steps required to set up a gateway from scratch, register it with The Things Network and observe uplink data from a simple LoRa node.
As an engineering firm that has successfully helped bring dozens of IoT products to market, establishing a presence in the technology hotbed of North Carolina’s Research Triangle makes good business sense. That is why we are extremely proud to sponsor RIoT…
Last month, more than 35 former Plexus Boulder Design Center employees convened at Cardinal Peak’s Lafayette headquarters to participate in a networking event aimed at both filling open positions and inspiring hope among a group of recently laid-off tech employees.
Earlier this year, the National Academy of Television Arts & Sciences (NATAS) announced the recipients of the 71st Annual Technology & Engineering Emmy® Awards, with Cardinal Peak consultant Kevin Gross earning recognition for his efforts that ultimately produced the AES67 standard in 2013.
I’m writing this post from the comfort of my hotel room in Las Vegas, where I am attending my very first CES. I’ve been in the tech industry for a long time, both as an engineer and in business development, which probably makes it more surprising that this is my first time here — especially…
Mmm — Brains. There are a lot of residential Internet-of-Things devices available that can connect to my home Wi-Fi network and provide some functionality: Thermostats, security cameras, light switches, connected speakers, and so forth. Some devices even defy classification. Cardinal Peak gave all its employees the choice to receive an Amazon Echo this past holiday…
