Need Help on 3.5 KM PtP urban link.

Hello

I am very new on wireless networking so please help me.

I am going to setup a backbond link between ISP and my office for redistribution of the bendwidth, when i contact a routerboard suppiler he suggest me the 711 5hn with a 22DBI INTEGRATED ANTENNA .

what i want to know is

  1. Is 711 5hn with a 22DBI INTEGRATED ANTENNA the right choice.
  2. How much bandwidth is expected with the said device.
  3. any other suggestion on other device.
  4. will it work well in nearLOS. (urban area)

Thanks in advance.

But… what are you going to do exactly ? MIMO uses reflections, so 711 “n” seems to be a good choice. Remember that 22 dBi antenna would be quite big, are you going to use parabolic antennas ?

What antennas uses your ISP on the base station ?

hi

On the both side I am going to use the same device, the device will use panel 22dbi antenna.

Main objective is to setup a backbone for Internet.

Thanks

Please help…

You should use RB711G 5HND or the newer RB911G 5HND because these router are dual chain, gigabit and the last has a 600mhz cpu. It’s important to know if there are interference because an panel with plastic box will not be a good solution. A very good solution will be an Jirous mimo parabola with metal case for router. Speed will be over 150mbps TCP. It’s an expensive solution but is the best one.

Jirous or Cyberbajt dual polarity parabolic antenna http://www.cyberbajt.com/en/shop_item/3138/sd_523hv_wb_box.html. As far as I know Jirous have some original plastic boxes to be used with parabolics. Plastic with some shielding inside also would be ok.

Is SXT G-2HnD or SXT G-2HnD will be a good choice?

2 sextants would be fine. Just configure them as bridge, there are hundreds of examples for that config.

Hi

One of suppler is recommend me to use SXT G-2HnD, it has only 10dBi antenna and Tx-power of 32dBm as compare to SXT G-5HnD 16dBi antenna and Tx-power of 26dBm.

I am in remote area, MT product is not very easy to get, so please suggest me a good one.

Distance between the Point to Point connection is about 3 to 3.5 Km

Thanks

Go for the SXT G-5HnD. You will get much less interference in the 5GHz spectrum.

If you dont know how to use MikroTik, update to the newest software (5.24) and use QuickSet for PtP config.

SXT G-5HnD should be ok for that distance, but doesn’t guarantee anything. In urban area where is a lot of 5 GHz stations there can be strong interference. If you aren’t able to set up MT, ask for the help MT consultants http://www.mikrotik.com/consultants.html or QuickSet.
