MOAR power to try to overcome attenuation and reflections from walls so more power bleeds into the next home/suite/apartment etc. <br><br>In the MSP space it's been rapidly moving to an AP per room with output turned down to minimum. Doing this we can reused 5Ghz channels 50ft away (through 2 walls etc...) without interference.<br><br>One issue with the RRH model is that to accomplish this 'light bulb' model, ie you put a light bulb in the room you want light, is that it requires infrastructure cabling. 1 RRH AP in a house is already a failure today and accounts for most access complaints.<br><br>Mesh radios have provided a bit of a gap fill, getting the access SSID closer to the device and backhauling on a separate channel with better (and likely fixed position ) antennas. <br><br>regardless of my opinion on the full on failure of moving firewall off prem and the associated security risks and liabilities, single AP in a home is already a proven failure that has given rise to the mesh systems that are top sellers and top performers today.<br><br>IMO, there was a scheme that gained a moment of fame and then died out of powerline networking and an AP per room off that powerline network. I have some of these deployed with mikrotik PLA adapters and the model works fantastically, but the powerline networking has evolved slowly so I'm seeing ~200Mbps practical speeds, and the mikrotik units have 802.11n radios in them so also a bit of a struggle for modern speeds. This model, with some development to get ~2.5Gbps practical speeds, and WiFi6 or WiFi7 per room at very low output power, is a very practical and deployable by consumers setup.<br><br>WiFi7 also solves some pieces of this with AP coordination and co-transmission, sort of like a MUMIMO with multiple APs, and that's in early devices already (TPLINK just launched an AP).<br><br>IMO, too many hurdles for RRH models from massive amounts of unfrastructure to build, homes and appartment buildings that need re-wired, security and liability concerns of homes and business not being firewall isolated by stakeholders of those networks. </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Mar 15, 2023 at 11:32 AM rjmcmahon <<a href="mailto:rjmcmahon@rjmcmahon.com">rjmcmahon@rjmcmahon.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">The 6G is a contiguous 1200MhZ.

There is no CTS with microwave "interference" The high-speed PHY rates <br>
combined with low-density AP/STA ratios, ideally 1/1, decrease the <br>
probability of time signal superpositions. The goal with wireless isn't <br>
high densities but to unleash humans. A bunch of humans stuck in a dog <br>
park isn't really being unleashed. It's the ability to move from block <br>
to block so-to-speak. FiWi is cheaper than sidewalks, sanitation <br>
systems, etc.<br>
<br>
The goal now is very low latency. Higher phy rates can achieve that and <br>
leave the medium free the vast most of the time and shut down the RRH <br>
too. Engineering extra capacity by orders of magnitude is better than <br>
AQM. This has been the case in data centers for decades. Congestion? Add <br>
a zero (or multiple by 10)<br>
<br>
Note: None of this is done. This is a 5-10 year project with zero <br>
engineering resources assigned.<br>
