到底AIMESH还有没有无线网桥速度减半的通病?

楼主 (未名空间)

马上要拿神由AC68们组AIMESH了,
突然想到这个问题。

觉得不管名字叫什么,
弄个路由器在二楼和一楼主由
无线通信,

和几年前折腾的wireless bridge / repeater
也不会有什么两样,
只是名字叫AIMESH而已。

应该performance不会好到哪里吧?
无线带宽减半的情况应该还有。

请明白人给说说?

谢谢!

你丫有病吧?

这个问题我也感兴趣,有谁测试过?

衰减肯定有的。它是用一个专门的5G信道做backhaul。我有一个节点离主机大概30尺,之间没有隔墙;一台电脑5G连到节点大概15尺,也没有隔墙。速度大概衰减20%-30%,
对我完全可以接受。

不过这个是手机版,是不是应该出门左转到硬件版。

和无线桥连一样
没什么意义
我的经验https://www.mitbbs.com/article_t/PDA/33060781.html
我组aimesh的另一个问题是
时不时的掉线
这个我完全没法忍
硬件版有个朋友也有这个现象
有人说是我们的固件版本问题

Conclusion
I really like the overall premise of AiMesh - the idea that you should be
able to add more routers to the router you already have and like, instead of needing to chuck it out and invest in a completely different mesh kit.

If you've currently got one AiMesh-capable ASUS router that you're really
happy with, adding a second in AiMesh mode instead of just using any old Wi-Fi extender isn't the worst idea. The comparison below brings together the
results from configurations that provided lower latency for all STAs than
the the solo RT-AC1900P.

If you don't have the option of Ethernet backhaul, you'd best stick to only adding only one AiMesh node (2 nodes WiFi bkhl). The results show lower mean application latency for all STAs with worst case latency of a bit over 850 ms for the most remote downstairs bedroom STA B.

Mean application latency comparison - best cases

Mean application latency comparison - best cases
If you have the option of Ethernet, my tests (3 nodes Eth bkhl No bndstr 5
GHz) show you can move up to two additional AiMesh nodes, but you'd best
force your devices to all connect on 5 GHz. Doing all this and maybe with a little bit of good luck, I was able to keep all latencies for all STAs below 400 ms.

The bottom line is that the data show that AiMesh, at least in its current
form, isn't up to managing STAs and backhaul connections when both use the
same pair of radios in each mesh node. And worse, AiMesh doesn't use
Ethernet backhaul effectively. So even if you don't need the (Wi-Fi) mesh
part of AiMesh and use Ethernet to connect all its nodes, it will give you
worse performance than manually converting the routers to APs and
configuring them yourself.

There are still some experiments I could have tried. For example, I could've tried dropping the 2.4 GHz transmit power to its absolute minimum and
running the 2.4 GHz-only tests again. AiMesh is also clearly not really up
to intelligently managing multiple-link backhaul; so I could also have tried pulling the downstairs RT-AC68U upstairs, and setting it up somewhere with a direct link to the RT-AC1900P router instead. I also could have introduced a tri-band router (or two) into the mix, to see if AiMesh could effectively use a second 5 GHz radio for dedicated backhaul.

But I didn't do any of those things because the tests I did run, which have provided the most detailed examination of AiMesh performance you'll find
anywhere, show there are much better, less frustrating and less expensive
options for Wi-Fi mesh systems.

Testing I've done for another publication has shown Orbi, eero, and Plume "
Superpods" were able to handle the same four STAs using Wi-Fi backhaul (
which is why you buy a mesh Wi-Fi system in the first place) and produce
comparable mean application latencies. While these compeing system's ain't
cheap, neither is the AiMesh configuration I tested. But they have the
advantage over AiMesh of not requiring Ethernet connection to provide as
good or better results.

Platform Configuration Price
ASUS AiMesh

- RT-AC1900P (x1)
$135
- RT-AC68U (x2) $280
NETGEAR Orbi RBK53 One router, two satellites $520
eero eero + two Beacons $398
Plume Superpod (x4) $460

And if your spouse is a believer that good Wi-Fi should not clash with the
home decor, then AiMesh is likely to lose that battle.

Which do you think will have higher SAF?

Which do you think will have higher SAF?
So again, If you don't already own an ASUS router and you're in the market
for a multiple access point system, there are frankly better options. If you have or plan to deploy wired Ethernet backhaul to your access points,
purpose-built wired access points such as Ubiquiti UAP-AC-Lite, TP-Link EAP-225v3 or other APs reviewed in the 2x2 AC Access Point Roundup series are
both less expensive and higher performance than AiMesh routers.

If you can't or don't want to use Ethernet backhaul and just want mesh, mesh Wi-Fi systems such as eero with a pair of Beacons still cost at least a
little less than most AiMesh options, and tend to be more stable, easier to live with, and higher in Spouse Acceptance Factor.
