@lx_allen:matrix.orgLX_AllenHi ๐Ÿ‘‹ there12:25:45
@lachezar:matrix.orgLachezarSo... When I try to bolster OpenWrt to my family, one relative of mine points to TP-Link's mesh devices beeing easy to throw around the house. Does OpenWrt support Mesh? Are there any devices on the market, that can have OpenWrt installed and do the same?14:29:16
@polymechanos:matrix.orgpolymechanos Iโ€™m pretty sure it does, but even if it doesnโ€™t, I think it would be relatively easy to set up something similar 15:09:59
@lachezar:matrix.orgLachezar polymechanos: Mesh is not easy... Sharing authentication session between cells requires cooperation that I am not sure is there OOTB. 15:14:01
@mhnoyes:matrix.orgmhnoyes802.11s is standard15:16:39
@mhnoyes:matrix.orgmhnoyesMesh (802.11s) sacrifices bandwidth for convenience. That will change with Wi-Fi 7. It has enough bandwidth that you probably won't notice a performance hit.15:35:54
@mhnoyes:matrix.orgmhnoyeshttps://en.wikipedia.org/wiki/IEEE_802.11be theoretical maximum of 46 Gbit/s15:38:17
@mhnoyes:matrix.orgmhnoyesFor all practical purposes, fiber is the only thing that will satisfy Wi-Fi 7 backhaul requirements. https://www.flukenetworks.com/knowledge-base/applicationstandards-articles-copper/category-8-cabling-fact-sheet All previous categories of balanced twisted pair copper cabling supported a Permanent Link Length of 90m (295โ€™) and a channel of 100m (328โ€™). Category 8 has a maximum Permanent Link Length of 24m (78โ€™) and a maximum Channel length of 30m (100โ€™) when supporting 25Gbps and 40Gbps speeds.15:48:40
@mhnoyes:matrix.orgmhnoyesNote: Cat7 is not an IEEE standard and is not approved by TIA/EIA. 15:51:49
@mhnoyes:matrix.orgmhnoyes * Note: Cat7 is not an IEEE standard and is not approved by TIA/EIA. Use Cat6A or Cat8. 15:53:54
@mhnoyes:matrix.orgmhnoyesFor reference 5G cellular theoretical peak download speed of 20 gigabits per second and 10 gigabits per second upload speed15:59:28
@mhnoyes:matrix.orgmhnoyesThis means the likely LAN choke point is the Wi-Fi 7 uplink port.16:07:40
@mhnoyes:matrix.orgmhnoyes * This means the likely LAN choke point is the Wi-Fi 7 uplink port. It also means there is plenty of excess bandwidth available for 802.11s. 16:12:34
@mhnoyes:matrix.orgmhnoyesExample: https://www.techradar.com/pro/tp-link-omada-eap690e-hd-access-point-review The supported WIFI standard is 6E, comprising 4804 Mbps on 6 GHz, 4804 Mbps on 5 GHz, and 1148 Mbps on 2.4 GHz for a total bandwidth of 10.8 Gbps.16:20:52
@lachezar:matrix.orgLachezarThis is $450 for one (https://www.amazon.com/dp/B0C448VPC1)16:53:32
@lachezar:matrix.orgLachezarThese are $130 for three https://www.amazon.com/dp/B084GTH5LL16:53:59
@lachezar:matrix.orgLachezar * These are $130 for three (https://www.amazon.com/dp/B084GTH5LL) 16:54:08
@mhnoyes:matrix.orgmhnoyesLook at the uplink ports.16:54:52
@mhnoyes:matrix.orgmhnoyesHow so?16:56:03
@lachezar:matrix.orgLachezarInternet speeds where I would be deploying these would be <100Mbit.16:56:36
@mhnoyes:matrix.orgmhnoyesThat's not the case for lots of people.16:57:06
@mhnoyes:matrix.orgmhnoyesEven Google is starting to offer 10GbE WAN.16:57:41
@mhnoyes:matrix.orgmhnoyes So you started giving polymechanos advice? 16:59:09
* @mhnoyes:matrix.orgmhnoyes wanders away shaking head.16:59:32
@mhnoyes:matrix.orgmhnoyesAnother bufferbloat test... https://speed.cloudflare.com/ https://developers.cloudflare.com/speed/aim/19:33:20
