Task Description

Communications between the rover and the base station will utilize 5 Ghz, 2.4 Ghz and 900 Mhz bands. Higher bandwidth bands, such as 5Ghz, will be prioritized for higher throughput, while 900 Mhz channels will be employed over long range. Transmitting antennas mounted on the base station are directional, and all receiving antennas mounted on the rover are omnidirectional and powered over ethernet. Once the rover’s mobility platform is operational, range, latency and video streaming tests will be conducted.

 

Task tickets

  • research on the current system way to benchmark and stress the communication system

  • setting up the site-to-site communication(Yuchen Lin)

  • documenting the development of the communication (Yuchen Lin)

Task Breakdown

Locate any existing documentation
Talk to any past/existing members who might know about the comms system (@Farris Matar / @Lance Bantoto (Deactivated) /Melvin/ @Ivan Lim )
Set up the simpler network topology (wireless bridge between the two routers with no VLANs) and test it
Set up the VLANs to eliminate switching loop between the routers
Investigate instability in VLAN network topology
Write documentation outlining how to use the current comms system
Verify that the current comms system will work for the competition
If it is not, outline what needs to happen to get the system working
Make a proposal for changes to the comms system or for hardware purchases that will improve or rectify the current system
Verify changes
Obtain a radio operator license well before Apr 28, 2023
Submit communications system details and operator license to URC by Apr 28, 2023

I’ll write up a condensed article/wiki on all the necessary theory to understand our network topology, but those videos are everything I watched to set up our current network.
