My understanding of it was that you had these lanes (I thought 80) within the spectrum. DSS chooses 2 and they were about a Mhz wide. What keeps you from interfering with others in that same channel was the luck that you didn't send your packet at the same time as the next guy. Being that the information that we send to our planes or helis is rather small, it doesn't take long to get it out. Like packets in an ethernet network. The problem begins when you have a system that is powerful (which generally means it oversteps lane boundaries), and it is Packet intesive(meaning that the time required to send the information is long, and the time between transmissions is very short). This would keep you from getting a word in edgewise.

I could be completely wrong about this. The reason for the above thinking is that the Receiver would not have any way of knowing which mini-lane to move (left or right) to in order to receive it's next packet. In FHSS the Rx is told where to go next, but with DSS, this is not the case. Therefor, it doesn't have the ability to veer around upcoming traffic in it's lane.

I liken the thought of spreading out the information as having a light freeway loading, where there is a lot of space between cars. The problem is that your Tx can't see the next car coming, but has to just jump in there and hope that he doesn't get hit.

My understanding is founded on the belief that there are assigned channels in 2.4. I think the way Spektrum/JR uses it. It takes the whole range and divides it into these channels, then picks them at random on powerup.

Also, I don't think we can really consider this transmission "broadband" as it may be wider than what we are used to, but because we can't limit the transmission to only one receiver (like that of a cable broadband), we can't use the entire radio wave spectrum, like cable broadband could use the entire useful electrical spectrum.

BTW, Opjose, I mean no disrespect in arguing with you, I want to know about this too and I want to make sure I understand it better.
