Creation of common biker 2-way radio channel?

[CookMySock]

jcxss, I've been toying with the idea of using a mesh-network style communicator using the 2.4GHz (802.15) range.

That would be interesting to hear about, from a techie point of view anyway.

We used channel 7

Channel 7 is one of the repeater outputs. Use a channel between 10 and 30.

Land sakes alive, looks like we got ourselves a convoy!

jcxss, I've been toying with the idea of using a mesh-network style communicator using the 2.4GHz (802.15) range. It'd be perfect for group rides or the 'bikes that pass in the night' scenario you mentioned.

It's a free spectrum, allows multiple senders at the same time and can be implemented on a relatively small (compared to CB) package.

If you're interested PM me, I've got a interest in electronics and a background in software.

2.4 is rather crowded/directional for voice chat isn't it?

Nah if its just voice its quite narrow-band and theres hundreds of MHz available. Yes theres a lot of stuff on 2.4 but its quite low power or tightly focussed. It will need to be frequency-agile so it can scoot around interference.

2.4 won't go over hills like VHF will. Even 450MHz UHF CB cuts off real hard in heavy terrain, even with high power and big antennas, so pretty much you are screwed either way.

If you are going to play with 2.4GHz and write code, then a huge amount can be done. Store-and-forward messaging would be fun - could be used to warn of road hazards and cops and the like.

Yeah, it's not much good unless you have line-of-sight. However, as it's a digital signal you can sacrifice usable bandwidth for extra distance and as as voice doesn't require much bandwidth (when encoded efficiciently) a balance could be found.

I suspect this would be much more useful in group rides than as a full CB style setup.

I can just imagine riding along and all I hear in my helm is hi,hi,hi,howzit,hello,gidday mate (that stupid aussie biker would say) all being said at the same time as every biker in a 10km radius is saying hi to each other. By that point I would gladly throw myself off my bike to stop the voices in my head and chalk one up to ACC. I mean it is a nice idea but logically come on.
