I'm new to RBE970/971 but old to all this netz stuff
I'm new to RBE970/971 but old to all this netz stuff. I have router, with 6 sats. Home is massive with cabling ranging from CAT5e from 20 years ago to recently pulled CAT7. All installed "a la Carrie...
Wow - you have a lot going on there., Do you have in excess of a 20,000 foot house? I seem to remember you have the gear to measure signals levels, have you seen how many Orbi devices have strong signal in any given area? I bet it's more than 1.
You seem to have the background for this but in case you have a VERY VERY huge house, you have way too many Orbi devices, and contention will cause all kinds of problems. Even though an 'extra' Orbi device may make the signal stronger in a given area, the overlap areas may be large and a contention of very strong signals will cause all kinds of problems. In the mesh world, 'more is better' is FALSE.
As a data point, I get very strong router signal from my router that is 3 floors away in an old house with much concrete between floors. Orbis have very strong signals.
Well said; you’re right as a general practice. Some insight in my situation...
Yes the home is well above 20k sqft at multiple levels; I also need to cover a swimming pool sitting 50 feet away from the home structure (position of the closest Sateliite). Note: I did state that WAPs are not closer than 50 ft apart "line of sight" with many walls of mixed construction to deal with concrete, plaster lath and sheetrock and studs.
I use MetaGeek wifi analysis tool with channelizer software to view the radio spectrum frequencies and energies. My past roles in telecom does include RF signal analysis for FM, satellite, microwave and mobile radios. (I was engineer for responsible for IBM’s microwave system spanning from Madison Ave in NYC, up the Hudson River, to Alpine, NJ, White Plains, NY, Poughkeepsie, Fishkill and Kingston NY. Corporate performance on this system back in the 80's was better than 1x10^9 BER for 18 years. This was achieved by modifying conventional tower spacing, precise frequency bandwidth, antenna alignment and power output. Also did 39 earth stations in the US/Canada to bypass excessive carrier tariffs and mobile radio schema while at BlackBerry.
In thjis estate, the closet neighbor is several miles away and the only radios in WiFi spectrum are those we generate in the home.
As you know... overdriving the RF signals would result in issues that would 'appear'
in the for of packet loss/retransmission, reduce window sizes and packet/bit errors. None of these were measured during test. Keep in mind that antenna design is important as signals travel radially (perpindicular) from the antenna. Thus in multi-level situations, RSS (relative signal strengths) drop off rather quickly. {{ Just a trick of the trade... if you need to travel vertically where these is no wiring, take two WiFi devices and lay their antennas flat/horizontally) and you'll have a wireless link going up several floors!).
The fundamental issue here is the Orbi Product not finding its own neighboring nodes on a completely wired multi-gigabit/10 gigabit L2 backhaul. There are no dependencies on wireless technology whatsoever! That's is a control plane problem (akin to how OSPF would be used in legacy networks to find neighbors and shortest paths across the interior network). NG has really messed up here with what appears to be shortcuts to put all thing wired and wireless into the same basket! The inability for the router to see its wired neighbors over the wired backhaul is totally inexcusable. RF interference matters can't be the root cause for the control plane not converging. Wired client physically attached to the LAN side should get to the main router NO MATTER WHAT via the physical fabric because there is no need or consideration for 'in-home roaming/mesh' techniques.
But as a general practice, your point is very valid as a general practice. If one has spectral measurement gear, you have a chance to exploit the rules to optimize the actual environment.
BTW.. your responses and comments (those I’ve read) were very much ON POINT. I can see you are a pro in this field and certainly have my respect. …marcel
