# EMANE Antenna Profiles
## Overview
Introduction to using the EMANE antenna profile in CORE, based on the example
EMANE Demo linked below.
[EMANE Demo 6](https://github.com/adjacentlink/emane-tutorial/wiki/Demonstration-6)
for more specifics.
## Demo Setup
We will need to create some files in advance of starting this session.
Create directory to place antenna profile files.
```shell
mkdir /tmp/emane
```
Create `/tmp/emane/antennaprofile.xml` with the following contents.
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE profiles SYSTEM "file:///usr/share/emane/dtd/antennaprofile.dtd">
<profiles>
<profile id="1"
antennapatternuri="/tmp/emane/antenna30dsector.xml"
blockagepatternuri="/tmp/emane/blockageaft.xml">
<placement north="0" east="0" up="0"/>
</profile>
<profile id="2"
antennapatternuri="/tmp/emane/antenna30dsector.xml">
<placement north="0" east="0" up="0"/>
</profile>
</profiles>
```
Create `/tmp/emane/antenna30dsector.xml` with the following contents.
```xml
<?xml version="1.0" encoding="UTF-8"?>

## Run Demo
1. Select `Open...` within the GUI
1. Load `emane-demo-antenna.xml`
1. Click 
1. After startup completes, double click n1 to bring up the nodes terminal
## Example Demo
This demo will cover running an EMANE event service to feed in antenna,
location, and pathloss events to demonstrate how antenna profiles
can be used.
### EMANE Event Dump
On n1 lets dump EMANE events, so when we later run the EMANE event service
you can monitor when and what is sent.
```shell
root@n1:/tmp/pycore.44917/n1.conf# emaneevent-dump -i ctrl0
```
### Send EMANE Events
On the host machine create the following to send EMANE events.
!!! warning
Make sure to set the `eventservicedevice` to the proper control
network value
Create `eventservice.xml` with the following contents.
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE eventservice SYSTEM "file:///usr/share/emane/dtd/eventservice.dtd">
<eventservice>
<param name="eventservicegroup" value="224.1.2.8:45703"/>
<param name="eventservicedevice" value="b.9001.da"/>
<generator definition="eelgenerator.xml"/>
</eventservice>
```
Create `eelgenerator.xml` with the following contents.
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE eventgenerator SYSTEM "file:///usr/share/emane/dtd/eventgenerator.dtd">
<eventgenerator library="eelgenerator">
<param name="inputfile" value="scenario.eel"/>
<paramlist name="loader">
<item value="commeffect:eelloadercommeffect:delta"/>
<item value="location,velocity,orientation:eelloaderlocation:delta"/>
<item value="pathloss:eelloaderpathloss:delta"/>
<item value="antennaprofile:eelloaderantennaprofile:delta"/>
</paramlist>
</eventgenerator>
```
Create `scenario.eel` with the following contents.
```shell
0.0 nem:1 antennaprofile 1,0.0,0.0
0.0 nem:4 antennaprofile 2,0.0,0.0
#
0.0 nem:1 pathloss nem:2,60 nem:3,60 nem:4,60

90.0 nem:1 orientation 0.0,0.0,0.0
90.0 nem:1 antennaprofile 1,45.0,0.0
```
Run the EMANE event service, monitor what is output on n1 for events
dumped and see the link changes within the CORE GUI.
```shell
emaneeventservice -l 3 eventservice.xml
```
### Stages
The events sent will trigger 4 different states.
* State 1
* n2 and n3 see each other
* n4 and n3 are pointing away
* State 2
* n2 and n3 see each other
* n1 and n2 see each other
* n4 and n3 see each other
* State 3
* n2 and n3 see each other
* n4 and n3 are pointing at each other but blocked
* State 4
* n2 and n3 see each other
* n4 and n3 see each other
