5Project Status
- DWAP Status - Alex
- Issue unable to get from DWAP LAN to
Infrastructure - Reconfigured DWAP to factory settings and started
from scratch - Resources used Monowall guide, ECE 158A,
Raytheon engineers - Final solution was reached NAT not configured
properly - This morning reconfigured both DWAP units to
operational status - Testing Design - Kehinde
- Received parameters from client
- Developed testing scenarios as will be shown
later - Will meet with client tomorrow to get more
direction

8DWAP What was the problem?
NAT Network Address Translation
NAT is a way to enable multiple hosts on a
private network to access the Internet using a
single public IP address
Issue In our case, we never told the WAN side
where to connect to hence the LAN side could
not communicate with the outside
9NAT Solution
SSID DWAP
NETWORK, ASSIGNED STATIC IP
LINKSYS ROUTER OUR DHCP SERVER
UCSD LAB PC
192.168.5.1
192.168.5.100
192.168.1.1
192.168.5.101
Solution We had to map the WAN side
(192.168.5.101) to the LAN side (192.168.1.1).
Once this mapping has been made (manually) there
is translation (NAT) between the laptop (behind
the NAT) and the PC outside the NAT.

10Test Design - Preliminary
- PHASE 1a Remote Clients and 1 DWAP wired in
lab - Linksys router will serve as infrastructure
- Client remotely connected to infrastructure
through DWAP - Run Bricks and Madi software and measure
throughput - PHASE 1b Remote Clients and 1 DWAP wireless
in lab - PHASE 1c Remote Clients and 1 DWAP wireless
outside the lab

11Test Design - Preliminary
- PHASE 2a Remote Clients and 2 DWAPs wired in
LAB - Linksys router will serve as infrastructure
- Client remotely connected DWAP_2
- DWAP_2 connects to DWAP
- DWAP connects to Infrastructure
- Run Bricks and Madi software and measure
throughput - PHASE 2b Remote Clients and 2 DWAPs wireless
in lab - PHASE 2c Remote Clients and 2 DWAPs wireless
outside

12Test Design - Preliminary
- PHASE 3a Remote Clients and 1 DWAP wireless
mounted on Aerial Platform - Linksys router will serve as infrastructure
- DWAP is mounted on Aerial Platform
- Client remotely connected to infrastructure
through DWAP - Run Bricks and Madi software and measure
throughput

13Test Design - Preliminary
- PHASE 3b Remote Clients and 2 DWAP wireless
mounted on Aerial Platform - Linksys router will serve as infrastructure
- DWAP is mounted on Aerial Platform
- DWAP_2 is _at_ ground level
- Client remotely connected to infrastructure
through DWAP_2 to DWAP - Run Bricks and Madi software and measure
throughput

14Action Items
- Complete Test Design
- Confirm that we have all the parts we need
- Begin building the infrastructure
- Install OpenWrT on Linksys router
- Begin testing next week
