Re: RB951-2n and Metal now shipping

Wed Jun 13, 2012 4:36 pm

How about two radios in a box, one for 2.4G and one for 5Ghz, both mimo (prepare for the future, make it 3x3) and each chain should have at least one horizontal and one vertical antenna.
Write some software that swaps between the antennas (per radio) and test the radio link to the client device which antenna chain actually gives the best results (ack)
This is why Ruckuswirelss is performing so much better in indoor environments with their 9, 12 or even 24 antenna's (per radio!). And all just with normal 802.11a/b/g/n chipsets. No proprietary tdma or nothing!
Now Ruckus is very costly and patent protected. But I'll bet MT can make something that is going an end in their direction for much less money without getting the lawyers on their neck.

Any that want to know how real Wifi should work should take a look at www.ruckuswireless.com.

From http://routerboard.com/pdf/414/Metal_5SHPn.pdf it says unit "Must be mounted with ethernet pointing down", can I ask does the unit come with right angle N-Connector adapter as most high gain antenna's have dipoles mounted horizonally.

"Dimensions 177x44x44mm, 193g. Must be mounted with ethernet pointing down"

wow, I totally missed that. Then this part is misleading, "completely waterproof". Or am I mistaken ?

These 90º N-connectors are a pain. You need to tape them in because on different models we used we found that the pressed-in part is letting water in the internal parts of the connector.
To tape such a 90º connector properly is a pain.

Also, for the signal a 90º corner is not good unless the unit is 1000% perfectly produced which most of the low cost connectors are not...

It would be nice if any manufacturer would come up with a better solution. Like a 45º connector or MT must make a better design.

The original plastic Grooves have 4 tiny little drain holes in the screw-on cap. Actually these are in horizontal position more prone to let water in than to drain any. (Try it under a shower...)
It would be better if these caps were just without any holes at all...
Or only one hole in the body located such that this hole is under where the text and LED are horizontally readable.

I live in a dry climate and have several Groove's horizontally fit. They never have water ingress problems after a shower or even a day long rain. In the beginning we used some with 90º connectors and they all gave issues with moisture after a while. So these are all replaced.

I also fit the Grooves such that in the event some drops of water might flush into the cap through one of the holes it would take some mm of water before any electronic part would be wet. So far we never had an issue with a groove due water ingress....

The metal will have a more sever condensation issue so here vertical fitting might be more important.

90º Adapter if totally sealed with two layers of self-amalgamating tape going in opposite directions will never have issues with water ingress

Just an FYI; a connector like this does not have pressed-in parts, so there's no need to tape the whole of it. Only found it recently, cheers.

Could you please clarify what is it that you wish to see in such a device, and why exactly the mentioned model? Has anyone actually tested it? Or you are simply comparing the features? If so, which features you need the most? 3 Chains?
Yes, 3x3 MIMO would be great for short range good performance, while 802.11ac wouldn't be available :D
http://en.wikipedia.org/wiki/IEEE_802.11ac
3 external (optionally detachable) antennas would be great too. For example I would like to have RB2011 with 3x3 MIMO and 3 external antennas. That would make it even better product.

hello,

can someone confirm is the maximum MTU on Metal same as on Groove and SXT 2028 bytes?

thanks!

Ideal for me:
1. Small device like 951
2. Gb ports like 751G
3. Port ground like 750UP
4. PoE on all ports like 750UP will be fine - but without 750UP bugs.
5. CPU performance like RB433UAH
6. RAM 512 MB
7. Storage 1024 MB will be fine.
8. microSD slot
9. Ideal 2USB Ports like RB433UAH
10. Internal 3G modem will be a plus.
11. 2 Wlan ports or maybe one and a mini PCI for expansion
12. RouterOS 5
13. Price 150-250$ ?

Thanks.

that's a great idea...
but i think it may not able to make it due to will creating high cpu temperature...

if the cpu can be at least power pc will be more attractive...

When you open RB951-2n there are two u.f.l. connectors for external antenna. Has anyone tried to attach better antennas?

I tried but it behaves as nothing is attached. No signal improvement at all.

It is NOT for external antena. This is conector for manufakturer testing

I like the IDU - ODU concept. How about a RB250G with an AP, no routing, PoE out on ether1, call it an RB251G-2HnD for this discussion. Your outdoor unit can do all the routing, including using VLANs to separate the AP from the ethernet ports inside the house. SwOS would probably need to be extended to know how to deal with the wireless device.

That way you don't need as much RAM and flash on the indoor unit.

A nice additional integration feature would be to have RouterOS on the ODU, SXT/Metal/whatever, recognize that it is connected to the RB251G-2HnD and be able to configure the RB251G-2HnD device as though it were all one integrated 751G-2HnD type device using the SwOS API. But that wouldn't be strictly necessary.

Most people who are unwilling to run ethernet in the home only need an indoor unit that would be a mythical RB211G-2HnD, probably the size of a Pacific Wireless PoE-24i.

I don't know what is considered a large apartment, but the 751U-2HnD does not quite cover my 2000 sqft (185 m^2) house with where I have installed the RB751U in the ham shack room at one end of the house (YMMV). By "cover" I mean the smartphone doesn't have enough antenna/power to associate from the far end of the 53 ft house. I take that as a sign that my house is too big, or too rectangular, and I should move somewhere smaller. :-) But a RB251G-2HnD I could hook up on the other side of the house would be nice. (Maybe velcro it to the back of the HDTV so I can plug the TV and the BluRay player into it via Ethernet). Then I could turn the power down on both RBs and have perfect coverage in a 3000 sqft (279 m^2) home.

That is strange. Why would that be on production version?

I'm curious about the same thing, however those connectors are not u.fl. It would be great if they were usable.

Has anyone managed to attach an aerial to J101 or J104 on the RB951-2n yet ?

Those are not antenna connectors. They are test points for factory testing
