INTRODUCTION
Point-to-multipoint is a communication technique in which a device (Access Point) transmits information to multiple devices (Subscribers or CPE) simultaneously. This technique is commonly used in wireless communication networks, such as radio links, to enable communication between multiple devices in a single network.
Access Point Configuration
Consider the following diagram for the access point configuration
Access the device and go to the Channel & Power tab
In this section, the following choices are made:
Protocol: 802.11-ax (the newest protocol at the moment, to maximize performance)
Channel Bandwidth (MHz): 80 (choose as desired, in this example it's 80)
Center Frequency (MHz): 5210 MHz (in the field, validate the freest frequency)
Max TX Power (dBm): 5 (for a laboratory scenario, the lowest is recommended)
Finally, save the changes:
Then, navigate to the SSID section and edit the default SSID, which comes as "Airspan".
Enter a name and password to identify it.
Finally, change the factory IP to avoid conflicts with the CPEs, as they also have 192.168.1.20. The IP will depend on the needs of each project.
Go to NETWORKING > Management IP
In the Management IPv4 section, set the desired IP, in this example, 192.168.1.22 (this will be the new IP for access).
With this, the Access Point is configured. Now proceed to configure the necessary CPEs.
Subscriber or CPE
For the Subscriber configuration, consider the following diagram.
First, go to SSID and edit the default one named Airspan to enter the SSID and password configured on the Access Point, in this case, it's A6X and Syscom123.
As a recommendation, also set a different IP for the Subscriber. To do this, go to NETWORKING > Management IP.
In the Management IPv4 section, set the desired IP. In this example, it's 192.168.1.21 (this will be the new IP for access).
With this, the Subscriber is configured. Repeat this process for all Subscribers to be connected (just use different IP addresses to avoid conflicts).
VALIDATION
By accessing the Access Point (in this example, 192.168.1.22), the dashboard will indicate the connection status.
