AraHaul Experiments

Experiment 1: Aviat Link Configuration (Microwave and Millimeter-wave) and Status Check

Resources needed: Aviat Networks mmWave and microwave radios (WTM 4800) and radio host servers.

Short Description: Aviat link configuration and measurement.

Detailed Description: The experiment allows users to measure the configuration parameters of Aviat radios and check related metrics. The following figure shows the experiment setup involving a long-range (~6 miles) microwave/millimeter-wave links.

Follow the steps below to create leases and launch containers for this experiment:

1. Login to the portal portal.arawireless.org with login credentials.

2. Create two reservations using the Project -> Reservations -> Leases tab from the dashboard.

   1. Aviat Host Computer at Wilson Hall

      • Site: Wilson Hall

      • Resource Type: AraHaul

      • Device Type: Aviat

   2. Aviat Host Computer at Agronomy Farm

      • Site: Agronomy Farm

      • Resource Type: AraHaul

      • Device Type: Aviat

3. Launch containers, using Project -> Containers tab in the dashboard, on both the reserved nodes using the corresponding reservation IDs. For containers, use the Container Image as arawirelesshub/aviatcli:ssh. Provide other attributes as per your discretion following the ARA Hello World Experiment.

4. Once the container is launched, associate a floating IP with the container using the Project -> Network -> Floating IPs tab in the dashboard. The floating IP allows you to access the container remotely through SSH via ARA jumpbox.

5. The containers can be accessed via the console tab of the respective containers in the Project -> Containers tab from the dashboard or using SSH via the jumpbox server.

Checking the Status of Link/Radio

6. For retrieving the carrier capabilities of the Aviat radio from local-end (i.e., measuring the carrier capability of Aviat Radio of Wilson Hall from Wilson Hall itself), execute the following command in the console of the container launched at Wilson Hall host:

   • For 11 GHz

     # aviatcli carrier show capabilities Carrier1/1

   • For 80 GHz

     # aviatcli carrier show capabilities mmwCarrier1/1

   To check the carrier capabilities of radio remotely, i.e., retrieve the capabilities of Wilson Hall Aviat radio from Agronomy Farm or vice versa, use the following command in the respective container console:

   • For 11 GHz

     # aviatcli carrier show capabilities Carrier1/1 --remote

   • For 80 GHz

     # aviatcli carrier show capabilities mmwCarrier1/1 --remote

   To check the carrier configuration status of local-end Aviat radio using the command below:

   • For 11 GHz

     # aviatcli carrier show status Carrier1/1

   • For 80 GHz

     # aviatcli carrier show status mmwCarrier1/1

     Example output:

Configuring the Link/Radio Parameters

7. In addition to the radio/link status check, ARA provides APIs to configure the radios and change the link characteristics. The following commands provide options for enabling/disabling, configuring, and checking the status of the link.

Note

Before changing the configuration, ensure the existing configuration of the carrier. In addition, if you want to change the carrier from Carrier-A to Carrier-B, strictly follow the sequence: (1) enable Carrier-B; (2) disable Carrier-A. For example, if the current carrier is Carrier1/1 and you want to change the Carrier to mmwCarrier1/1, first you should enable mmwCarrier1/1 and disable Carrier1/1.

The basic API usage of Aviat radio configuration is as follows:

aviatcli carrier [OPTIONS] COMMAND [ARGUMENTS] ...

For example, for getting help on the OPTIONS and ARGUMENTS, use the following command:

aviatcli carrier --help

Note

Provide --help option to any command to get usage information from that level onward.

8. Enable the microwave carrier, i.e., Carrier1/1

   # aviatcli carrier enable Carrier1/1

   Example Output

   root@demohost:~# aviatcli carrier enable Carrier1/1

9. Configure the Aviat link characteristics.

   Get help on the provided configuration options with the following commands.

   # aviatcli carrier configure --help

   # aviatcli carrier configure all --help

   The basic API usage of Aviat configuration is

   aviatcli carrier configure [OPTIONS] COMMAND [ARGUMENTS] ...

Caution

Take sufficient care while changing the radio parameters.

Configure radio with the configuration: (a) bandwidth 50MHz, (b) transmit frequency 11250000 KHz, (c) receive frequency 10745000 KHz, (d) modulation of QAM-2048, and (e) transmission power of 26 dBm.

# aviatcli carrier configure all -b 50 -t 11250000 -r 10745000 -f qam-2048 -p 26 Carrier1/1

Example output

root@demohost:~# aviatcli carrier configure all -b 50 -t 11250000 -r 10745000 -f qam-2048 -p 26 Carrier1/1
