RF Coaxial Cable: Impedance and Shielding in Wireless Networks

Coaxial cables are the unknown heroes on wireless networks, inconspicuously connecting our devices with each other. One of the critical factors that'll help determine their performance is impedance, which is similar to resistance that the signal encounters as it passes through the cable. On the other hand, shielding is an important factor in reducing interference and signal integrity. In this part, we will further illustrate how these parameters affect the performance of RF coaxial cable in wireless networks. 

The Role of Shielding for Wireless Networks

It is as if the inner conductor was insulated from electrical noise because of a shield protection cable wrapped around it. Without shileding in place, signals can get confused and deteriorate as they cross from one signal to another. Picture trying to hold a conversation when you’re in a room filled with lots of others, all talking at the same time - it would be very hard to follow. Everyone knows what rf cable are: They're the kind of wires that provide excellent shielding, like a noise-canceling option for your signals. 

Why Do You Need RF Coaxial Cables For Uninterrupted Connectivity? 

RF coaxial cable are used to transfer a low-power radio-frequency (RF) signal from one location to another, such as for between a RF-Transceiver and an antenna. Their low-loss support in transmitting high-frequency signals render them invaluable for a wide range of applications, from telecommunication industry to aerospace. Call a friend, text your mom, stream some television or transmit that satellite signal again, rg rf coaxial cable are there conducting the signals to keep you connected and entertained. 

Achieving Optimum Signal Integrity Through Proper Shielding Methods

Appropriate shielding is necessary to preserve the integrity of the signal, and reduce interference in wireless applications. Choosing these materials to cover the inner conductor, coaxial cables can prevent external electromagnetic interference and maintain the integrity of your signal while it’s en route. For the analogy-impaired, consider shielding as the armor that protects the fragile signal moving through the cable and gets it to its final destination smoothly. 

What Affects the Impedance of RF Coax Cable in WLAN? 

There are several things that can affect the impedance of an RF coaxial cable, such as the size, materials used and construction of the cable. The diameter of the inner and outer conductor, the type of insulating material between them and the effectiveness of the shield all effect this measurement.
