Cellular Connectivity for Wearables: Choosing Between NB-IoT, LTE-M, LTE Cat 1bis, and LTE Cat 4
If your team is designing a connected wearable, one of the earliest and most consequential decisions you will face is which cellular technology to build around. Get it right,
When a PCB antenna for Bluetooth device is the right choice?
For Bluetooth device designers, a Bluetooth PCB trace antenna, also called a PCB antenna, microstrip antenna, or printed circuit board antenna, is rarely a trivial decision. On paper, this
Choosing the right antenna for IoT
Reliable wireless connectivity is arguably the most important feature for IoT devices. When developing an IoT device, one or more antennas must be chosen for the device. With a
Kickstarting Your Wirepas Project Effortlessly: From Idea to Reality
Ever wondered why some Wirepas projects succeed while others stumble right out of the gate? In many cases, the difference comes down to one thing: how you start.
3D-Printed Antennas: A Game-Changer for RF Prototyping and Lightweight Designs
3D printing or additive manufacturing has been around since 1980s. At first, it was seen as a way for fast prototyping. In recent years, it has been increasingly popular
Is LTE-M the Key to IoT Success?
As the Internet of Things (IoT) expands, LTE-M is becoming the core of successful, efficient IoT solutions. With features that enhance battery life, ensure stable connectivity, and expand network
Lower Costs with Optimized Antenna Design: 5 Tips
In today's competitive tech landscape, every dollar counts. At Radientum, we've seen firsthand how smart antenna design can significantly cut costs for companies developing wireless products. Let's look at
Employee experiences: Summer Intern, Venla
We had the pleasure of working with Venla Vastamäki this summer. She returned to Radientum for the second round of internship. Venla is a bright and motivated student pursuing
Optimizing Connectivity: Antenna Solutions for Wearables
In the fast-paced world of wearable technology, where innovation is the driving force, antenna development plays a pivotal role in shaping the user experience. Wearables, such as augmented reality
Enabling the I in IoT: Antennas in IoT Product Development
The importance of antennas in IoT product development cannot be overstated. The antenna is the device’s interface to the outside world; it is the component that enables the “I” in
Chip Antennas in Plastic Devices: An Example of Integration Problems
Antenna Integration Challenges: Follow the Instructions or Fail When we design devices, our perspective differs from the end-user. We create a device piece by piece, where as the
Boosting R&D Investment: Simulation-Driven Antenna Design
In our previous blog post, we talked about the importance of antenna design and testing. This time we are delving more deeply into antenna simulations: why are they at
How is Your Antenna Doing? An Overview of Antenna Testing
As technology advances, diving into the highly technical world of RF can be a challenge to anyone – even those with an engineering degree! We want to bridge this gap
Antennas for Smart Frisbee
How to make a frisbee “smart”, bringing a new level of precision and connectivity to Disc Golf, empowering players to analyse their throws in real-time and unlock insights for
Using two 5G modules? – Key antenna considerations
The latest cellular generation, the 5G, is the ultimate low latency, high data rate network solution but can still suffer from poor coverage unless you use two 5G modules.
Pre-layout work and good signal integrity simulation
Digital signals controls all the devices today. A failure in signal integrity simulation creates unwanted phenomena like sudden freeze of the device or unknown software error. These happens when
Employee experiences – Henna Hurskainen
Who am I? My name is Henna Hurskainen, and I started as an assistant at Radientum in September 2022. As a student of international relations and economics I saw
CDF EIRP and sPD in 5G mm-wave Mobile Phone Simulation
When designing mm-wave 5G device, engineers have to compline with specific limits and metrics according to industry standards and safety protocols. The two most important metrics in 5G mm-wave
Electromagnetic compatibility (EMC) in 5G mm-wave USB dongle
Electromagnetic compatibility (EMC) usually is not the first thing in mind while working with mm-wave antennas. An engineer has a lot of challenges to solve within the antenna itself,
Hardware potting – 5+1 tips to avoid problems with antennas
Why potting is used First, what is hardware potting? It is a process where you protect electronics from various effects by filling an enclosure of the electronics with a
CST Studio Suite: Domain Decomposition Solver vs. Time Domain Solver
When designing and simulating periodical structures, like arrays, the engineer wants to have a reliable tool, that doesn’t require hours of setting up. Simulation time plays a significant role
Electronics testing – Happy versus Unhappy testing
I wish I would have come across this terminology earlier when I was teaching electronics designing. It would have been so much easier to categorise the different electronics testing
5G mm-wave chamber
Mm-waves have become a well-known and desired frequency band, thanks to 5G FR2 and RADAR applications. Antenna designers have learned how tricky antenna systems can be on those frequencies
Challenges and Solutions in mm-wave Antenna Design
In the beginning of August I gave a presentation on #EMC2021. Event lasted whole week and gathered a lot of 5G and mm-wave enthusiasts. I was talking about my
Dual-polarization in mm-Wave 5G technology
Nowadays almost every specification for 5G device states dual-polarization as a basic and mandatory feature. Dual-polarized antennas became a part of everyday work for most RF engineers, but mmWave
