Can this topic be free from how to’s and which bits and pieces one is experimenting with?
** try and keep on topic.
And if one has “thoughts” (be they ever so jumbled) one can also just reuse a post that one has, by editing it (like I do with this one)
Decreasing costs and availability of Real GW’s: may mean some issues disappear.
False hopes of coverage by “coverage” on the TTN Map: The map should only show “the real thing” as defined by core team
Pollution of the RF: where pollution is the generic term of a byproduct of what one wishes to achieve
If there is one GW in the area (and maybe only ever be one) why not a directional antenna on a device so that the RF is kept clear in other directions to avoid pollution.
Collision domain and physical limits:
node, repeater, bridge and router (Ethernet LAN: the old yellow stuff)
in relation to
device, missing1, missing2 and GW (TTN type LowPowerWideAreaNetwork)
missing1: a “thing” to allow line of site to a missing2 or GW (missing1 does not necessarily have to support many devices as it is “filling a hole”)
missing2: a “thing” that is a full blown GW without Internet connection to connect to a GW with Internet Connection. Internet is sometimes “hard” in an area with many devices that do not have LoS to a GW.
In respect to capacity (single channel “GW”): missing1 can be “interesting”.
Remember: newbie alert (with experience) but no knowledge of previous thoughts as to how to fill the holes of LoS with “GW”'s for few device, lack of easy Internet connectivity, for many devices
Ethernet yellow cable:
Based on CSMA/CD:
Carrier-sense multiple access with collision detection
LoraWAN? (which I “Like”)
Carrier-sense: not sure, transmit and pray
Multiple access: yep
Collision detection: almost, just throw the packets and hope for reception, or try again (which is also fine)

Original first post
Edit the edit
htadvisser kindly added more information later https://www.thethingsnetwork.org/forum/t/the-future-of-single-channel-gateways/6590/31?u=owenbrotherwood
So, what is the minimum channels to be a full GW, and why the “some even ten” in some context
Edit
I answer, my own question, 8 but the 10 is confusing.
As a newbie, I presume 6 spreading factors is a constant and is in the specs (I don’t need to read as such: just comply when purchasing a GW)
https://www.thethingsnetwork.org/wiki/Hardware/Gateways/Single-Channel-Gateway
- needs revision: has the 10 and no mention of band
Edit
Latter in the topic, I read that there are systems with even more channels, which puts the original first posts 10 in context https://www.thethingsnetwork.org/forum/t/the-future-of-single-channel-gateways/6590/19
“LoraWAN has the concept of bands”
So maybe, one day, there will be a discussion on GW’s that only support single bands …???
