Posts about RF (Radio Frequency) technology, offering analysis, design principles, applications, and latest innovations.
Some time ago, I wrote a post about the importance of understanding the Wi-Fi capabilities of mobile devices. The post dives deep into how these capabilities influence Wi-Fi network modifications and the decision-making process. You can read more about it here. When designing or upgrading …
Introduction to Antenna Concepts Antenna Types Omnidirectional antennas Semi-directional Antennas Planar Antenna Sector Antenna Highly Directional Antennas Yagi Antenna Parabolic Dish Antenna Grid Antenna Antenna Comparison Understanding Antenna Radiation Azimuth and Elevation Charts Interpreting Polar Charts The Logarithmic Nature of dB Scales Practical Application Beamwidth …
In the world of wireless design, an engineer must strike a delicate balance between coverage and performance. A high-speed wireless network doesn’t happen by accident. It’s the outcome of careful design and consideration where the art and science of Radio Frequency (RF) mathematics come into …
As a Project-based Network Engineer, I’ve had the ‘pleasure’ of encountering a considerable number of bugs while deploying network infrastructure over the years. Sometimes, these ‘bugs’ have enough impact to grind operations to a halt. With a bit of luck, the challenges will arise early …
Many factors contribute to the successful transmission and reception of a wireless signal. This post will focus on the most common Wi-Fi communications components and each device’s role in transferring data in wireless systems. Wi-Fi Component Overview The image below illustrates the key components discussed …
What is a Radio Frequency? Radio frequency (RF) is a form of electromagnetic energy typically used in wireless communications systems. RF signals are generated by a transmitting device as an alternating current (AC) which produces electromagnetic waves as it radiates away from the device’s antenna. …
You’ve just purchased some shiny new Wireless Access Points from Vendor X. Vendor X has promised you lightning-fast, wired-like connection speeds. Product datasheets speak of incomprehensible Wi-Fi data rates and sky-high maximum client connection limits; it all sounds great! You deploy the APs which are …
This article outlines the complete list of 802.11 standards and amendments and is updated as developments are made. As each 802.11 standard is updated by the IEEE, the previous iterations and any amendments that exist at the time are revised and incorporated into a single …
