6 Communication System
In order for the FLOCS system to display orientation and position data back to the user, a rugged
and flexible communications system was needed. This system consists of a four key components
● On board Ethernet connection
● Wireless Transmitter (Ubiquiti Bullet)
● Wireless Receiver (Ubiquiti AirGrid M5)
● Computer with Ethernet connection
Shown below is an overview of how the components are connected together in the final project. The
section in orange is the portion on the transmit side, and the green section represents the receive
side of the system.

6.1 On Board Ethernet
The on board Ethernet port is used to send out data packets from the board to the rest of the
system. As discussed in the sensor package section 5, the Ethernet port is mounted directly on the
board and and contains its own oscillator. Since the Ethernet port configuration was identical to the
EVK1100 Demo board system, we were able to make use of the lwIP port to the AVR32.
