If you want to test it on lab, attach it a little omni antenna (2dBi), or buy a dummy load at 50ohm.

Have you tried to use this howto?

mipland

it would be much cheaper to use a rootenna, any ideas as to if the solder ing would work?

You can't simply "solder" another connector on the antenna, it will result on a unbalanced antenna impedance.
If you want to use a dual-band antenna, you have to use a diplexer.

mipland

Uhm...sorry, no diagram.
What i want to say, is that on your card you have TWO line on pcb to the diversity switch, and it's probable that you solder connector on the wrong line. Try to solder your pigtail/connector on the other line, and try if you have some tx power.

mipland

You have no TX becouse:
- you have specified the wrong tx connector on ROS;
- the card transmit ONLY on one connector, and it is not which you soldering on.
- the TX section is damaged.

Small change?
I remember you that -102 is the HALF of -99!

mipland

It simply called "XR" feature. It introduce 4 new bitrate level: 3-1-0,5-0,25 Mbps.
-120dBm is not true.
It's -105dBm for about 250kbps (raw).

mipland

If you are (as me) a radioHAM, for example, in Italy you can use 2300-2450.

mipland

I have a RB153 with a Mikrotik R52, and with the superchannel license it goes all over the custom-frequency provided, 2.3-2.5 and 4.9-6.1GHz.

mipland

I am sure in a couple of months the bugs will have been worked out of the XR cards if you are willing to wait.

But...is there any knowed bug?
Where are you listen XR5 are bug's afflicted?

mipland

Hy Mike, and thanks for your presence here.
Please, can you post here the answer to "planedriver" 's question?
I think it's VERY useful for all other forum's member!

Or prepare your e-mail address to receive 1000 times the same question soon...

mipland

the spec sheet for the xr5 supports 40mhz channel bandwidth spacing, im assuming this is another term for turbo mode, no ?

Yes

mipland

Yes, I know it...my answer was for jo2jo.

mipland

Also what about he RB 153s? I cant find any vendors with them.

Take a better look on aerial.net, they have RB153. It will be available from 2007-03-20.

mipland

I have a RB153 with: - 1 x Mikrotik R52 - 1 x Ubiquiti SR5 - 1 x Senao NL2511+ on board. It's my Mikrotik Test Board. :wink: The max power consumption is: 1,320W R52 4,620W SR5 2,475W NL2511+ (as declared on web-sites, becouse on datasheet they declare <=280mA-->0,924W) 4,000W RB153 ------------- 12...

mipland

Sorry for the mistakes.
I just installed 2.9.39 and I confirm that it can works well.

mipland

Just tested under a 3.0beta5, and it doesn't recognize it.

Platform used:
- PC x86 Celeron 500
- PCMCIA-PCI adapter
- Senao PCMCIA 200mW

On same platform, but with ROS 2.9.27, it goes ok (recognized and perfect funcionality).

mipland

Anyone can post a copy of those package (wireless-legacy) updated? I need it too, becouse I have a Senao 2511Plus mPCI to put on a MT 112 with ROS 2.9.38. I downloaded 2.9.35, 2.9.37, 2.9.38, 2.9.39 (the only "all package" version available on this syte), but no "wireless-legacy"...

mipland

60Mbps+ FDX

But, only with one wireless card on each site?
2,4 or 5GHz?
Turbo?
Nstreme?

Thanks

mipland

Maximum power consumption for RB112: 3-4W (let's assume the maximum)
Maximum power allowed for RB112: 10W
Maximum power allowed for RB153: 13W
Maximum power consumption for SR2: 1400mA * 3,3V = 4,62W
Maximum power consumption for two SR2: 9,24W
Total power consumption (board + two SR2): 13,24W

mipland

From specs, RB153 can handle two SR card, but an RB112 cant't handle, becouse of power lack.

mipland

From specs, RB153 can handle two SR card, but an RB112 cant't handle, becouse of power lack.

mipland

For two reason:
- the simpliest: there's lower noise on 5800 than 5500;
- your antenna is not correctly adapted to 5500.

mipland

Hy Equis,
currently I have an hotspot + backhaul running on a RB112 with SR2 (hotspot) and CM9 (backhaul), and it's working fine.

mipland

Yes, you are right, but this is not MT, this is basic physics...

mipland

So , a BTS with -120 Noise Floor is better than a BTS with -90 Noise floor .. Correct ?

Yes, i think this is obviously.

mipland

You have to make a new bridge, and then add the wlan1 and the ethernet to it. The IP address have to be configured on the bridge, not on the eth1 nor wlan1.

mipland

Follow at the letter my howto, and you will have a basic (but functionally) hotspot.

I want to understand if 300 meters without obstacles could cause interference between my APs. Sure, but it depends by the antenna gain and orientation. You can use channel 1,1,6, placing the same channel (1) on the two ap which are on the opposite side. Take a look at the antenna's orientation for ...

mipland

After seen your nick i thought: "this is an italian boy".

Ok, you have a new mail.

mipland

I don't know what's the meany of "U" (i'm Italian), but elementary Ohm law says:

V=Volt (potential)
R=Ohm (resistance)
I=Ampere (current)
P=Watt (power)

V=R*I

P=V*I-->R*(I^2)

For Senao: V=3.3 I=1.3, so P=V*I=3.3V*1.3A=4.29W

mipland

So , every senao have a consumption of 1.3A . At 12v the cosumption is out of range ....

Senao and all other mPCI is 3.3V, NOT 12V. So, if we assume the max current consumption:
Routerboard: 3W
Senao 8602 Plus (FCC/ETSI) : 3.3V*1.3A=4.29W

Routerboard + 2 x Senao 8602 Plus = 11.58W

mipland

Finally...I did it! 111,7km, 5825MHz NO Turbo, nstreme (normal, not dual).

Hy, as the subject said, where can i find that mPCI card on Europe? I found only Business-to-Business seller. But, no online seller for private user? I found one on eBay, but it's from USA, and he wants 45$ for the card and 49$ for the shipment!

If you use amp, users will have strong signal, but noise will be enormous and surfing will be worst then on dial-up.

If 5GHz are connected to only one other point (Point-to-Point link), the bandwidth will not limited, becouse it is a PtP link!

mipland

So i wonder that this limitation is also valid for Mikrotik ROS?

Obviously. This is a phisical limitation, and there aren't way to substract from it.

mipland

Baisickly, the routers know how to send packets forward in your network (twards the gateway), but MikroTik2doesnt know how to get packets back to the far end of MikroTik1

Sure, and the default gateway on Mikrotik2 is the way (or a static rule).

mipland

Ok, so, as csickles suggest, check your firewall rules.

The client has a Linksys WRT54GL and a VAGI 16dBi antenna. But, can you explain why can't install NMP-8602 on a laptop? High power consumption? Other?
