Re: Just an idea...regarding the recent FMS problems

Feel free to disagree but from the research I have done and speaking to knowledgeable FTA's and network engineers, the field setup they have right now is fine (note that is just the field, not robots).

There is nothing wrong with the current PLC system used for field IO and even the Cisco AP that is used to create the 7 WLAN's with the respective SSID's for each robot, 6 out of the 7 WLANs have a VLAN. The 7th WLAN is used for the pit monitor and the FTA monitor can be put on a tablet or laptop and used wirelessly.

The problem exists with the DLINK bridge system. We are using this unit for a different purpose than it was intended. Some may argue that it only happened to certain teams so that isn't the issue but it truly depends on the unit you have and where it was mounted. I personally think that FRC should switch to Cisco Aironet 1300's. These are a rugged wireless system that is meant to be abused. The only problem with these is the price is about $700 per unit. But maybe they can mitigate by moving some more components over to FIRST Choice and instead of buying as many components they buy the 1300's. And maybe dependent on Cisco's corporate health they can assist in funding as well.
