Spring 2016 Pathfinder CSULB Wi-Fi Mapping
By Xiong Lee (Mission, Systems, and Tests)

Introduction:
For us to finish our objective, we will need to be able to access the Wi-Fi from CSULB campus. One of our requirements is to have the pathfinder explore the campus and since we need Wi-Fi, we will have to map out the best Wi-Fi signal we have here at CSULB. Using the Wi-Fi Maximiser app, we were able to map out the Wi-Fi at CSULB.
Steps:
- First, we need to download the Wi-Fi Maximiser app on your phone here.
- Next, we need to be connected to the network that we want to map out. (for us, it is the beachnet +)
- After that, we need to have a map of CSULB because we are mapping out the campus here.
- Once we import the picture to the app, we can walk around campus clicking on the map every time we want to see the Wi-Fi signal we receive. (Note: we can only click on the map 20 times, then we’ll need to do another map)
- After we finish mapping out the Wi-Fi, we can generate the map with details and send to our email.
Results:
These are the results we got from walking around CSULB. We first did the lower campus and then the upper campus.
Lower Campus
If you look at the dots on the map, it is labeled by a letter at the upper right of the dot going in alphabetical order from A to T (we can only scan 20 points at a time hence, A-T). These are the data received from the app which tells us the ping, lost packets, received packets, and whichever network we’re on at each location we monitored. Point A starts at the rec center and then we walked around in a clockwise direction ended up at point T (which is at the Pyramid). (The green spots are where we can received the best signals and red spots are the poorest signals.)

university music and dance department:
On this map, we only monitor 4 points which can give us the details below. As said above, the points are labeled from A to D. We started from the left near the pyramid then went to the right towards parking lot 12. The generated heatmap shows us the best Wi-Fi spot in the area that we monitored. (Green is where we received the best signal and red is the poorest signal.)

Conclusion:
As you can see on the generated maps, the green area are where the best Wi-Fi signal is. On the other hand, the red is where the poorest Wi-Fi signal is. The green area is where we want to launch our pathfinder and explore the area for 4 hours. These maps are not done to a 100 percent accuracy but, it will do because we just want to know the general area we can explore.
