---|
8 | This module provides a simple wlan_exp example. |
---|
9 | |
---|
10 | Hardware Setup: |
---|
11 | - Requires 1+ WARP v3 node running 802.11 Reference Design v1.5 or later |
---|
12 | - PC NIC and ETH B on WARP v3 nodes connected to common Ethernet switch |
---|
13 | |
---|
14 | Required Script Changes: |
---|
15 | - Set NETWORK to the IP address of your host PC NIC network (eg X.Y.Z.0 for IP X.Y.Z.W) |
---|
16 | - Set NODE_SERIAL_LIST to the serial numbers of your WARP nodes |
---|
17 | |
---|
18 | Description: |
---|
19 | This script will initialize the given nodes; extract any APs from the |
---|
20 | initialized nodes; then for each AP, it will get the associations and counts |
---|
21 | and display them. |
