Channel Spectrum Width

20M represents the data transmitted at a bandwidth of 20MHz. 20/40MHz represents the data transmitted at either 20MHz or 40MHz. In very noisy environment it automatically fall back to 20MHz to be more resilient to the interference. In situation when auto fall back did not happened, manually changing channel spectrum width to 20MHz will to help reduce interference on the link and improve performance.

*Note: 40MHz bandwidth is non-standard for 802.11n/g mode operation. If you experience unstable performance change Channel Spectrum Width to 20M.

Channel – Frequency

This is frequency selection you can set for device to operate on. The frequency range available depends on the country domain you select in Country Code. For 5GHz frequency range some have DFS characteristics earmarked by regulations. Selecting one of these frequencies for operation may affect and delay of 2 minutes or more (possibly up to 10 minutes in some situations) for device to attempt to establish a connection.

Auto: When checked, during startup, device automatically select the least interfering channels (or frequency) for the operation.

Data Rate

Data Rates consist of both the legacy rates and the MCS (Modulation Coding Scheme – Only for 802.11n) rates.

6 – 54Mbps are Legacy Rates

MCS0 to MCS7 are 802.11n rates, which uses only 1 stream. MCS8 to MCS15 are 802.11n rates, which uses 2 streams.

Auto: The data rate selected will follow an advanced rate algorithm that takes into condition the amount of errors at the data rate and fine tune to the best data rate it can use.

Transmit Power

The maximum transmit power displayed is determined by the country code and the maximum transmit power of the miniPCI that is being used.

*Note on changing channels:

When the operator changes the channels and if this new frequency have higher power output permitted by regulation, the power previously selected low power level will remains unchanged. You need to readjust the power level to in order to take advantage higher output power available for the channel

.

Rate Aggressiveness

Allows user to reduce or increase transmit rate while still remain in Fully Auto Algorithm. There are 2 scenarios that Rate Aggressiveness is useful. Environment might be noisy at times. Lower the throughput will ensure better stability. Rate Aggressiveness allows device to reduce the transmit rate, so range or power can be higher. Choose a range of value from -3,-2,-1.

Environment might be free of interference. But the fully auto algorithm might give low throughput. Increase Rate Aggressiveness will increase transmit rate in this case to get higher throughput. Choose a range of value from +3, +2, +1.

802.11N specifications

Compex Systems 802.11N solutions are designed to provide high-performance wireless networking, catering to the growing demand for faster and more reliable connectivity in various applications. The 802.11N standard, also known as Wi-Fi 4, significantly enhances the capabilities of previous Wi-Fi standards by utilizing advanced technologies and features.

One of the key characteristics of Compex Systems 802.11N products is their support for Multiple Input Multiple Output (MIMO) technology. MIMO allows the transmission of multiple data streams simultaneously, effectively improving throughput and range. This is especially useful in environments with high user density or physical obstructions, as it enhances the signal quality and minimizes interference.

Another significant feature is the use of Channel Bonding, which combines two adjacent channels to double the data rate. This capability enables users to experience higher speeds, typically reaching up to 600 Mbps under optimal conditions. The dual-band operation, supporting both 2.4 GHz and 5 GHz frequencies, further enhances flexibility and performance. The 2.4 GHz band offers broader coverage, while the 5 GHz band provides faster speeds with less congestion.

Compex Systems also incorporates advanced security protocols in their 802.11N solutions. With support for WPA2 encryption and robust authentication methods, users can ensure that their connections remain secure, protecting sensitive data from potential threats.

Quality of Service (QoS) is another critical feature, allowing network administrators to prioritize traffic according to application needs. This ensures that bandwidth-intensive applications, such as video streaming and online gaming, receive the necessary resources for optimal performance, even in a crowded network environment.

Designed for versatility, Compex Systems 802.11N devices can be employed in various scenarios, including enterprise, education, healthcare, and hospitality sectors. Their compact and durable designs make them suitable for deployment in both indoor and outdoor settings.

Overall, Compex Systems 802.11N solutions offer a comprehensive set of features and technologies aimed at providing robust, high-speed wireless connectivity. With MIMO, Channel Bonding, dual-band support, enhanced security, and QoS capabilities, these systems are well-suited to meet the demands of modern wireless networking environments.
