Problems with Current Comms System

  • Cannot reliably enter the Agile OS on multiple attempts

    • Cannot enable POE on router - this is required for all further comms systems

  • Why do we have 6 receiver antennae?

    • There is probably some justification (aka transferring certain types of data over different antennae)

    • Do 6 antennae strengthen the signal?

    • Are the receiver antennae used for specific ranges?

    • Lots of redundancy?

  • How much data do we expect to transmit over the comms system (average and peak)

  • What are the battery requirements for the rover antennae?

    • Battery needs to last an hour and a half max over a mission; do we need idle, high speed data transfer modes?

  • It appears we have stronger antennae in the bay - why are we not using these?

  • Base station is very large and very heavy → 20 min to set up

    • Center of mass and spacing isn’t really proper

    • More than one person is required to set up the base station (ideally one person required)

  • What is the feasibility of streaming video over long distance and long range?

  • Omni directional antennae vs active tracking system to address line of sight issues

  • When we are out of line of sight

  • How can we connect an operators control system to a base station? Long ethernet?

  • A lot of teams use multiple frequencies bands depending on their distance from the base station

  • Why can’t we just use one band? It is recommended to use two from competition rules, but we should see why first.

  • Do we need a network, can we use P2P?

 

Potential Development Paths Forwards

  • 1km wifi extender plus router

    • Buy OTS 1km ethernet router (relatively cheap) and new extender

    • Supports 2.4 and 5Ghz bands

    • Is a competition viable solution (potentially)

    • Unknown if other teams use this
