New 568m Link Question

RouterOS Wireless Networking
1

Hello!

I have just discovered MikroTik today on a recommendation by a DD-WRT member. I would like some recommendations for hardware for my link.

My two points are 568m distance from each other. The connection is in a urban downtown environment. The 2.4ghz range is very overcrowded. 5ghz unknown. I want 100mb connection or better.

I have a clear line of sight, on towers 30ft off the ground. I have a Omni 5ghz 54g AP on one side now, with two 16dbi gain 54g Units pointing back. I can go higher on the tower if i can keep the current setup for redundancy, or remove them.

I love the price point on the RB-SXT, and read in another thread it would achieve the 100mb link with ease. I’m open to any suggestions, and thanks for your time!

Two RB/sxts in bridge mode will meet your requirements at that distance. Definately the best cost effective solution.

Well i ordered two of the RB-SXT to try out. I was hoping for a warmer welcome from the experienced members.

It’s surprisingly very quiet here right now, even from the MikroTik staff.

I’ve posted my results with my two devices sitting on my kitchen table in the beginners section. I was hoping to get some more help there.


I’m very glad to hear things are quiet, i was beginning to think this was a ‘no new guy’ forum.

Sorry for my previous short response. i can give a little more information. I’ve been in the wireless world for <10 years, though new to this forum.

The RB/SXT’s are a great little unit. you can speed up the TCP speed on them in a bridge type setting using something called MPlS.

I find with MPLS i can get TCP speeds above 35-40 megabits. UDP assuming good Wireless speeds are near 85-90m full duplex. (MPLS enhances tcp speed by lowering cpu some)

pay attention to the guide and make sure you add the correct interfaces to the bridge if you’re going to give it a go :slight_smile:

on the SXT’s make sure to enable all 4 Tx/Rx chains and the extension channel, and remember with the NV2 and Nstreme protocol it has a long guard interval, meaning you will only see air rates of up to 270/270, which will max out the units ethernet port anyway..

Thanks for the response. I’ll give that a test!
