4km PPTP link with 100mbits full duplex

Tue Apr 24, 2012 4:12 pm

Hi,

I need to pass 100mbits internet line over a 4km wifi link, i know that is possible to use link aggregation. (perfect LOS)

What products do i need and antennas.



Thanks

RBSXTG-5HnD, tho I haven't done it myself yet.

I would probably build my own with a higher gain dual polarity grid or dish. RB433GL with R52Nm.

IT Elite has a 21dBi dual polarity panel that sounds like a good fit for this.

I have 2 units RBSXTG-5HnD from the fist version that needed to drill two small wholes, and i cannot get more than 30mbits, maybe bad configuration or something, but the antena looks small for 4km.


thanks

I've got a 26dBi grid on a 7 mile shot, signal is around -50 if I leave everything default.

Your signal should be in the mid -60s. I'd prefer a tighter beam, but 4km/2.5 miles is a really short distance. I have longer 54mb shots with 10 and 15dBi panels.

ItElite has some dual polarity 21 dbi panels, 5GHz 711G, signal would be quite strong, probably have to turn down the tx power.

It is not how small the antenna is but what is the Gain and transmit power of the radio using the link calc one should get a reliable link 20 Km using the Sxt

Now i need some help to get 110mbs/s full duplex in my 4km link.

I have it connected using nv2, but i need to align the antenas a litle bit more.

you could design your own systems using mikrotik boards and radios....

will turn out efficient....

you can use dual polarization 24dbi antenna ex jirouse with rb433ah and 2 ub5 cards, one for transmit and one for recive, load the rb with RadioOS from asn.pl software and you will have a 97mbps/97mbps true speed. I have just tryed a link with one polarization with a simple one card A only r52 i got 45mbps /45mbps full duplex speed . software modulation is TDD.

:) good lock

What is this RadioOS and what miracles it performs? I did read their web, but what they claim is not convincing for me. I can write anything myself in my webpage.. Are these figures achievable in real life, or it's just in theory. How does it compare with RouterOS? More info please. Preferably from own practice

i have purchased two license from them, one prime and one bis, the only problem that i have is that i cannot scan and is difficult to put radio on clear chanel without scanning but i have made some tests, one is made with prime version and mikrotik 411ah and r52 i was able to archive 35/35 fdx, the beautiful is that you can set the link ex: 70% with 30% and the same link now perform 50/20 ,this is TDD Time Division Duplex, with dynamic ARQ like ligowave, saf-freemile etc, this days i will test a dual polarization link with jirous 24dbi RB433 and UB5, link will be 3km, i hope to archive 99/99 fdx. i will post results here. if will be true is a good invest, TCO of a similar link is les then 1000eu .

i can bet RouterOS can achieve equal or even better speeds with fdx if configured properly.

try that to on the same hardware.

agjini, I'm sure we all would like to hear your results and comparison. SAF Freemile is a product of completely different league. And a p2p link out of those costs at least 4-5k EUR. It'd be nice to see how they compare despite all the circumstances and clear advantages of Freemile..

hello, today i tested one of the links with ub5 and 24 dbi jirous extreme antenna, link is aligned only with eye I have not made alignement properly.

the test was made with laptop and mikrotik bandwith test tool at remote site. distance 3km. frequency 4980 width 40mhz.
Signal lever 32db laptop---RadioOS-2<<<-->>>>RadioOS-1----cisco---Nstreme-Dual-1<<<<<-->>>>>Nstreme-Dual-2--Cisco-Cisco-Cisco--Mikrotik Border Router.

NstremeDual is with simple r52 cards distance 800 metter.
Mikrotik is small supermicro server.

Speed which i tested 40/40 duplex. ping during speed with mikrotik-router 17ms. there are 2 backhauls and 4 cisco switch in the middle.

I have changed throughput ratio (%) from 50%/50% to 70%/30% link reached about 68mbps on one direction. and the card is UB5 simple "a" card.

i think that with antenna alignement and other tuning it can reach 65/25 asimetric bandwith easy. and is still very good i think

i will post results with dual frequency next 2 days.

It can be not compared with freemile becouse of diffrent hardware, but software modulation scheme i think are similar TDD.
