I would like to implement a wireless network in rural are where there is no object between the AP and the client

and the client is in the constant movement(mobile)

1-what is the maximum distance range if i use two omni directional anntena?

2-which frequency (2.4 or 5) can be used?

i can sacrifice the bandwidth to latancy

you dont need to use two omini antenna .using one omini antenna with high power access point (1000mw) is very enough

2-which frequency (2.4 or 5) can be used?

both are usefull depends upon the clients

Two antennas are better than one if they bring more signal to connected radio. Better to use a ring of many panel antennas covering full azimuth. Too much power from Ap is for nothing. You need to clearly hear the client as the mobile has weak radio and weak antenna. So the selective receiver on Ap is a must.

I believe i have mis-represent my question as whole.
I have to RB-METAL which each of them has one omni directional (6db) anntena. what is the maximum range or distance for this two devices?


Thank you in Advance

And what is maximum distance of your phone?

one RB-METAL is at static position and the other RB-METAL is in movement and nothingin between causing obstruction and there is also no interference at all. Cause, it is not in urban are. so both omni directional can see wach other no matter what

Oh. You wrote "mobile" before. In this case of two metals moving around in clear environment few kilometers can be reachable with no problems. Use as narrow band as possible (5mhz) to gain high power to frequency density. With fine tunning at place I believe you can reach 5 to 10 kilometers expecting you do not need high speed.

Thank you very much for your response.
That is exactly i was expecting to hear.
actually the bandwidth is not an issue for us. latency and link stability is playing major role in our scenario.

What speed do you expect at the moving side? 54 Mbps? 1 Mbps? or is 300 kBps enough?


For the 54 Mbps....: stay close (within 20 meters) of the fixed antenna. For 300 kBps: well, it can go several kilometres (or miles).


The further you go you less speed.


So your question should be: In a LOS situation, with tow Metal RB's, I need to achieve 500 kBps (fill in the numbers you want). What is the maximum distance I can achieve?

And do not forget, radio (RF) spectrum is very very "jumpy".

Thank you for making my question understandable.

I would try various channel widths.

As mentioned above 5Mhz wide channel will have the strongest signal, however I've found that 10MHz seems to be the sweet spot. More resilient to loss of signal, variances you'll likely have while moving about. Every situation is different, so the only way to know for sure is to test it and find out.

Ok thanks,
i will share my result as soon as i conduct my research on that
