The terms verification and validation are often used when developing IoT devices. They are both important to a successful product launch, but often people are confused about the differences [...]

The successful development of any product starts with establishing good requirements. Requirements are at the core of everything – the step before a design blueprint – and the reason things can [...]

Design Verification Test (DVT) is the process of checking each aspect of a new device’s design to ensure it functions as required. Most engineers understand that if they design a new enclosure, [...]

This is it; this is the year that 3G dies. All major carriers have announced their 3G sunset plans in 2022: AT&T will sunset their 3G service on February 22 T-Mobile will sunset their 3G [...]

Security in cellular IoT systems is often misunderstood and occasionally neglected. Those new to IoT may assume their device will have a public IP address on the Internet, or that a VPN is [...]

We’ve talked about IoT device size and how cellular radio performance and antenna performance are basically constrained by North American carrier performance requirements in opposition to end [...]

When you’ve worked on hundreds of wireless products, you start to see patterns. Radio performance problems specifically brought on by the size of the product is something many of these devices [...]

When developing a new product, one vital consideration is often overlooked: Cellular carrier certification. Doing so can be detrimental to project timelines and budgets, as test failures are all [...]

Why isolation testing matters When a product or system has more than one radio and at least one of them is a transmitter, there can arise intermittent interference problems where the signal from [...]
