Slow ramps for efficient Wi-Fi

Sometimes it’s better to make the most of what’s already there than to move on to the next nice, shiny thing: that’s the case with wireless LANs. Rather than jumping to a new, higher spectrum and the many design, propagation and testing issues that come with it, IEEE 802.11ax makes better use of the bands […]

How to achieve Wi-Fi design freedom with a fully integrated module

Embedded system designers face many challenges in selecting the appropriate components to meet functional, budgetary and regulatory requirements, especially when wireless technologies are involved. Until recently, adding Wi-Fi meant learning and implementing complex software subsystems just to provide the deceptively simple wireless networking. Typically, this requires digging into an embedded operating system (such as Linux), […]

Analysis of the optimization scheme of grounded coplanar waveguide RF feeder

The Signal Integrity Group at Arira Design was asked to redesign the existing 5GHz grounded coplanar waveguide RF feedline to improve the performance of the Wi-Fi subsystem on the customer’s board. Measurements show that the impedance of the feeder impedance is about 38 ohms. Before simulation, the original design identified several issues, including: Unable to […]

About Attenuation and Free Space Path Loss in RF Waves

We note that wavelength, speed, frequency, and amplitude are the defining characteristics of a wave, but we’re also interested in another thing (if you forget what it is, you might want to go back and read it again). re-read the column). We also note that each RF protocol depends on RF wave behavior or wave […]

Are 5G and Wi-Fi 6 Converging or Competing?

Wi-Fi is a wireless local area network (LAN) technology that is mainly used indoors, such as in the home or workplace. The cellular network used by operators is a wide area network (WAN) that can be used both indoors and outdoors. In the industry, the debate around the convergence of Wi-Fi and cellular networks has […]

Exploring Wave Mechanics for RF Communication Protocols

As we all know, Wi-Fi is a radio frequency (RF) communication protocol. While there are many Wi-Fi-specific details, there are also aspects that are fundamental to any form of RF communication. Every RF protocol depends on RF wave behavior or wave mechanics. Let’s say it out loud: “wave mechanics”. I love the sound of it! […]
