TX power, short for transmit power, refers to the strength of the signal that a Wi-Fi device sends out. It is a critical specification for wireless communication devices and refers to the amount of power used by the radio transmitter to send signals. Higher TX power generally translates to a greater range and better signal penetration through obstacles like walls and floors. However, there are trade-offs, as higher TX power can also lead to increased interference and reduced battery life for portable devices. 

The smart design of Silex's Wi-Fi 6/6E AP modules for TX power

TX power in access point modules is crucial for determining the performance and coverage of a Wi-Fi network. It affects the coverage, signal strength, interferences, network planning, and energy efficiency of a Wi-Fi network.

Silex’s SX-PCEAX-AP series are Wi-Fi 6/6E wireless LAN access point modules using Qualcomm’s QCN9072 chipset. They are designed to carefully balance TX power effectively, ensuring robust coverage without causing excessive interference. This balance is crucial for maintaining reliable connectivity in environments where there are numerous wireless devices and potential sources of interference.

Hardware designs of other AP modules are generally reference designs, and may not be optimized for real-world performance. Silex customizes its modules for actual use cases, balancing TX power trade-offs to suit various conditions.

The SX-PCEAX-AP uniquely includes a built-in filter to mitigate interference from other wireless devices. An RFI filter enables it to reject specific frequencies or types of interference within a power line or signal. While this filter helps to improve signal quality and reduce noise, it can have a negative impact on the output power spec. Specifically, the filter can slightly reduce the maximum TX power, which might appear as a disadvantage in pure specification comparisons.

However, in practical terms, this added filter enhances overall performance by providing more reliable connections in environments with significant interference. Silex believes that real-world performance is a more meaningful metric than theoretical maximums, and our product design and specifications reflect this philosophy.

Product specs: realistic performance vs. highest potential maximums

Silex rigorously tests its product specifications under a variety of conditions, ensuring that each module consistently meets its stated performance metrics. Unlike other providers, we don’t rely on optimistic estimates or guidelines; our listed specifications reflect the actual performance customers can expect in real-world applications.

We focus on realistic performance metrics rather than theoretical maximums because it’s what’s best for our customers. This approach provides them with accurate expectations, better planning, improved performance, and fewer technical support issues. It’s the Silex reliability—"When It Absolutely Must Connect."

TX power is essential for Wi-Fi performance, but achieving optimal results involves more than maximizing spec numbers. Silex’s Wi-Fi 6/6E AP modules balance TX power and integrates a built-in RFI filter to ensure robust coverage with reduced interference, prioritizing true, reliable performance.
