I’m going to connect two Ethernet networks with a Wireless Connection and the distance between them is about 18km , i don’t know what kind of MikroTik equipments I should use to help me with this
Please i need your suggestion about what equipment should i use
Thank you in advance.
Note :
the temprature my reach the 60 C.
Hi Nett2k
We have successfully got Point to Multipoint link of 23.9km
We use the following equipment:
Senao Routerboard 532
3 X 120 deg sector antennae
1m of LMR400 between routerboard and antenna’s
Atheros mPCI 802.11b adapters with 200mW output
Client Stations use
Senao Wireless AP 802.11b running 200mw radios
Check with your local authorities if this would be legal.
for point to point link at that distance with clear line of sight , almost any wireless equipment will work with strong enough antenna on both ends.
One of the clients that we have is actually connected with a SMC pci 802.11b/g adapter that is connected to an external antenna with 3m LMR400 cable. The antenna used is 24dbi Grid and this works upto 15km with 11mbits through put.oh! and this radio is 100mW. It should also work on 18km no problem.
Our base station is 15m off ground level and client antenna’s range from 6m-15m off of ground level.
Obviously the higher the antenna’s are the greater the distance you can get with wireless equipment.
We do not have a problem with any interferance as we are the only users on the 2.4Ghz band, as well as no tall buildings in the area. very flat surface with no mountains or hills within immediate vacinity of the base station, in fact the closes high peak of about 100m is about 120km away.
On the furtherest link we have very low noise…almost nothing, and we get ping times of 80ms and less.
hope this was helpfull
thank you for your help but 11mbps is a bit slow i need at least 54mbps speed please.
thank you
You should be able to get at least 36mbit using 54mbit cards, and connect using Nstream if you only have one station that you want to connect.
You will need to have two antenna’s on each end though.
to maximise speed and through put.
Theoretically it is possible.
Depending on how much you want to invest in the setup.
You might even be able to get full 54Mbit if your signal levels are ok, but I doubt it in a built up area.
You might search for calculators to see what theoretical recieve vallues are and that way be able to see what speed you can get with the various cards available.
At this stage I understand that only Atheros and Prism II / III cards are supported by mikrotik and prism II only 11Mbit not sure about Prism III but atheros has 54Mbit cards.
I am sure you will be able to get the speed required using Nstream. You will have to find someone on the forum to help you as I have never tried it myself, as our speed is fine for all our traffic, as well as our network games.
RX Antenna P))----------((9 Tx Antenna 36mbit
TX Antenna P))----------((9 Rx Antenna 36mbit
Router Board Router Board or other equipment supporting Nstream
Total throughput of 72Mbit
As I said in previous post we got point to multipoint working with very good signal, so point to point 54mb should be able to be possible,
24-30dbi grid antenna P(((------------)))9 24-30dbi grid antenna
Ant height 3m Ant Height 3m
Theoretical signal on SMC AP 54Mbit = -60.790 dBm
which is 10dbm within the 54Mbit tx range…so theory says you can do it.
don’t know wether this includes calculation on earth curve, but visable horison is normally 20km so you should not have a problem. especially as the antenna will be raised above eye level.
Oh! Somthing that I missed.
We are situated in the Kalahari in Botswana, and temp here somtime reaches 50 deg C in shade, and MT router has no problem although some thermal fade on signal.
But we don’t get internet cos our Satellite router bombs out…so we sit with only lan.
If I understand correct the MT router should not have a problem opperating at this temp. but I would still implement means of cooling the MT, as it may damage the MT over time.
High and Very Low(-40 for egsample) temps are never good for hardware.
The plastic enclosures on the market when in shade drops our temps inside the casing about 10degC so our system runs near 40degC
