Hi,
It is a very nice and I take a lot of time to made a RB411 + Built in 5/2,5GHz 802.11a/b/g card

Today RB for AP (wireless)?

RB 433 only a 3 cards (one card for traffic in, one card out and one card for ap) – hmm int in not too much
RB 600 it is N/A - excelent board
RB 800 problems with temperature.

And others ?

And for client?
RB 411 + Card 5G (because onboard is only 2,4G)
Now may be RB711, but 1 MMCX connector
Very nice – excellent choice:
- New type connector (incompatible with UFL)
- only one connector, so for MIMO (2 antennas) its impossible.

So the unpopular qestions to RB Engineers is :
Why do not ask the ISP- Your customers before You preparing a new type of routebroard ???????? (ie. RB with only 2,4G card)

In the hight quantity the price go down, so prepare few universal boards for everything (ie. 3-4 : client (all mode, all band), AP, Network router) !
You should develop what costumer needs. !

Have a nice day

MT don`t ask ISP becouse this is business.

example:

When you need 2x antena connector for MIMO then you must buy RB + minipci_card with 2conn.

The last RB releases: 800(big temperature problem), 711(no dc jack, no plastic case) and maybe 1100 (slow CPU) is hopeless.

711: depends on the Price. May be for very cheap clients.
1100: is a good upgrade for rb450g

New type connector (incompatible with UFL)

RB711 is also available with uFL

711(no dc jack, no plastic case

it's for outdoor, you don't need dc jack and indoor case

only one connector, so for MIMO (2 antennas)

speed difference is too small, for most clients it will be perfect. also, why need 2 connectors for more wireless speed, if you have 100Mbit ethernet anyway?

OK but i use indoor all RB411

711 is cheap alternative but DC connector I need.

I would say that it's not an alternative if it doesn't provide any of the features you personally need You need to wait for the one with DC and indoor case and built in antenna ...

You're kidding normis. Hard to get 100MBit out of 11n with MT. Just read your forum
Using dualpol has one big advantage. You're free to change polarisation without touching
the antenna. So you're able to get signal separation. As interference kills your
11n/nstreme Implementation this is needed.

we get 100Mbit easily. All about configuration. We have real links.

What is the price of a second anntena connector and power jack ?
it is not more than 1$.
It will be very nice:
- have RB with 2 connectors.
- have RSMA onboard - easy connect to antenna, wihout any reduction. !

I and other ISP give more $$$ for one universal WISP tiny client. One type RB for any client, 2,4G 5G, 5G MIMO 2x2

So and HW for proffesional AP? When will be avalible ?

yeah, and some other people will need a miniPCI slot, or a serial port, or a SIM slot.

there are other devices that have those.

if config=get a free tower and a free band you're right. But this config is seldom.
On our towers no config leads to 100Mbit on one chain but using different polarisation
helps to get 60-70.

if you have no available channels and lots of interference, no existing technology (for 802.11) will give you speeds above 100mbit.

I'm just saying that it's possible if your conditions are right:

If they are very bad, I can't imagine how an improved protocol could help

To keep on topic: Having a second channel on another polarisation helps simple by
switching to it to reduce interference problems.

I see problems even with free channels but channels on the same band used.
Even with 60Mhz separation we suffer from interference. Using 11a with R52 this
is no problem but 11n with R52n is much more sensitive to signals on the same
band.

An improved protocol can make the best out of bad conditions.
I see nstreme help a lot in good conditions but make things worse on bad conditions.

So I think there has to be done some work on the RF-Side and some work on nstreme
to make it more robust.
