#### **Status**

Enable/Disable the Radio.

#### **Link Type**

When configuring a wireless network, understanding the connection mode between Access Point (AP) and Subscriber Unit (SU) radios is crucial. The connection mode is determined by the *Link Type*, which can be either:

* **Point-to-Point (PTP):** A direct link between two points, ideal for connecting two locations.
* **Point-to-Multipoint (PTMP):** A single central point connected to multiple locations, suitable for networks with one central AP and several SUs.

#### **Radio Mode: BSU / SU**

* If the Radio Mode is BSU, it is considered as AP.
* If the Radio Mode is SU, is selected then it is a SU.

#### **Service Set Identifier (SSID)**

SSID is simply the technical term for a network name.

#### **Country: US 5 GHz**

* Band1: 5170 - 5250 MHz
* Band2: 5250- 5330 MHz
* Band3: 5490 - 5710 MHz
* Band4: 5735- 5835 MHz
* Operational Mode: 11AX

#### **Bandwidth: 20/40/80/160MHz**

Within the available configurations, administrators have the option to adjust the bandwidth to suit their needs. Specifically, the 2.4 GHz band supports a 20 MHz bandwidth, ideal for short-range connectivity. Conversely, the 5 GHz band offers greater flexibility with bandwidths of 40 MHz, 80 MHz, and even 160 MHz. Opting for a 5 GHz setting with increased bandwidth has several advantages:

* **Enhanced Speed:** A wider bandwidth facilitates quicker data transmission.
* **Higher Data Capacity:** It allows for the transmission of more data in the same time frame.
* **Reduced Signal Interference:** These settings help minimize interference from other signals.

It's important to note that this enhanced bandwidth flexibility is exclusive to Access Point configurations and is not available for Subscriber Units.

#### **Channel**

A channel can denote either a physical transmission pathway, like a cable, or a virtual route over a multiplexed medium, such as a radio channel in wireless communication, designed for relaying messages to a desired recipient. Wi-Fi operates across specific channels; each channel number corresponds to a predefined frequency range optimized for maximum communication performance.

#### **Traffic Shaping**

By default, traffic shaping is turned off. To limit traffic, operators can define shaping policies. Once these policies are in place, traffic shaping can be activated by setting specific uplink and downlink limit values.

#### **Uplink Limit**

The administrator can only configure this bandwidth limit if traffic shaping is activated. The allowable bandwidth range spans from 64 Kbps to 867,000 Kbps, facilitating data flow from the Subscriber Unit (SU) to the Access Point (AP).

#### **Downlink Limit**

The administrator has the capability to set bandwidth limits only when traffic shaping is activated. These limits must fall within the range of 64 Kbps to 867,000 Kbps for traffic from the Access Point (AP) to the Subscriber Unit (SU).

#### **Max SUs**

This parameter can be adjusted only in Access Point (AP) mode, accepting values ranging from 1 to 32.

#### **Retries**

This setting enables configuring the number of attempts for re-transmitting a packet.

### MIMO

To configure MIMO, Click ***Wireless> Radio 1 or Radio 2 Configuration > MIMO***

<div align="left"><figure><img src="/files/iZwWZOEsAy6h3iaZaFU1" alt=""><figcaption></figcaption></figure></div>

EOC655 Series devices support Multiple-Input-Multiple-Output (**MIMO**) antenna technology that uses multiple antennas at both the transmitting and receiving end to improve communication performance.

The transmitting antenna uses multiple radio Tx chains and signal paths to simultaneously transmit different data streams, whereas the receiver combines the Rx signals, resulting in a higher throughput. Increasing the number of receiving and transmitting antennas increases the channel’s throughput increases linearly, resulting in high spectral efficiency.

### DDRS/ ATPC

<div align="left"><figure><img src="/files/AiM7FeuSPrfZHtoEfUKs" alt=""><figcaption></figcaption></figure></div>

#### DDRS

To configure DDRS/ATPC, Click ***Wireless> Radio 1 or Radio 2 Configuration > DDRS/ATPC***

Dynamic Data Rate Selection (DDRS) feature adjusts the transmission data rate to an optimal value and provides the best possible throughput according to the current communication conditions and link quality.

Select the Spatial stream as either Auto, Single, or Dual.

* **Auto Stream**: When you select Auto, DDRS decides the stream modes based on the environmental conditions.
* **Single Stream**: Select Single for reliability and longer range.
* **Dual Stream**: Select Dual for higher throughput.

{% hint style="info" %} <img src="/files/c9b20maiKERxgPDboQw8" alt="" data-size="line">

The data rate can vary from min to max based on SNR and Retransmission percentage.
{% endhint %}

#### ATPC

To configure ATPC, Click ***Wireless> Radio 1 or Radio 2 Configuration > ATPC***

* **Adaptive Transmit Power Control (ATPC):**

Adaptive Transmit Power Control (ATPC) is a feature that dynamically adjusts the device's transmit power. This is essential for preventing the saturation of the remote receiver, which can lead to data errors, reduced throughput, and potential link outages. When ATPC is enabled, the device autonomously manages its transmit power levels to maintain optimal performance.

* **Manual Adjustment:**

In cases where ATPC is disabled, it's necessary to manually set the transmit power. It's important to select a value within the permissible range of 1 to 26 dBm to ensure reliable communication and avoid overpowering the receiver.

### Security

The Wireless Security feature helps to configure security mechanisms between AP and SU. To configure Security, Click ***Wireless> Radio 1 or Radio 2 Configuration > Security***

<div align="left"><figure><img src="/files/l3IbFYuSdWBeDm65QYZO" alt=""><figcaption></figcaption></figure></div>

#### **Encryption Type**

Select AES-256

#### **Key**

Select any desired key considering the note below.

{% hint style="info" %} <img src="/files/c9b20maiKERxgPDboQw8" alt="" data-size="line">

If the encryption type is selected as none, then there exists any security to the data frames transmitted over the wireless medium.
{% endhint %}

### MAC-ACL

MAC Access Control List is an additional security mechanism in a wireless network. To configure MAC ACL in AP (5GHz), Click ***Wireless> Radio 1 or Radio 2 Configuration > MAC ACL***

<div align="left"><figure><img src="/files/HxWpzhanyj6L6p0MHWUN" alt=""><figcaption></figcaption></figure></div>

#### **MAC status: Allow/ Deny/Disable**&#x20;

* **Allow**: If Allow is selected, the MAC ACL feature allows only the authenticated SU’s to access the wireless network of AP by adding their MAC addresses.
* **Deny**: If Deny is selected, only a particular SU is restricted.
* **Disable**: By default MAC ACL is disabled in AP (5GHz) Configuration, i.e., all SU’s are linked to AP.

#### **MAC ACL table**

MAC Address

{% hint style="info" %} <img src="/files/c9b20maiKERxgPDboQw8" alt="" data-size="line">

The maximum number of SU\~\~’\~\~s that can be added to the MAC ACL table is 32.

MAC ACL feature is applicable only in AP with 5 GHz.
{% endhint %}

### DCS (Dynamic Channel Selection)

To enable DCS, Click ***Wireless> 5 GHz Radio Configuration> DCS***

<div align="left"><figure><img src="/files/EN5v12jZ17QTyUlcC5aI" alt=""><figcaption></figcaption></figure></div>

The Spectrum Analyzer identifies channels with minimal interference and connects the Service Unit (SU) to the most optimal channel available. The Dynamic Channel Selection (DCS) parameter enables an Access Point (AP) to track packet retransmissions to the connected SU on the current channel. If the average Local Retransmission (RTx) percentage for the associated SU exceeds the configured DCS threshold, the AP will assess the local RTx percentage for 30 seconds before initiating a channel switch and instructing the Spectrum Analyzer to scan the environment.

{% hint style="info" %} <img src="/files/c9b20maiKERxgPDboQw8" alt="" data-size="line">

* This feature is available only in AP with 5GHz.
* The DCS threshold is a user selectable range (0-100) % and is activated only when DCS is enabled.
* The default chosen DCS threshold is 20%; when this percentage limit exceeds, the AP activates the spectrum analyzer.
* Respective logs will be generated under Monitor> Link Statistics > Logs> Wireless section for example: : DCS triggered (**when SU request AP**) : DCS selected best channel (**When AP assigns new channel to SU**)
