we have a project which needs the support of a rather large wireless network. The goal of this project establish a bus system video monitor network. Now we have a preliminary solution to implement the project :
Firstly, we choose the RB433AH to establish our base station which contains two 11N wireless cards: the 5G AN and the 2.4G BGN. The AN is used to support the backbone network and the BGN is to satisfy the coverage.
Secondly, as whole network will contain lots of RB433AH base stations, we use the combination of optical fiber and AN MESH to construct the backbone net.
Thirdly, as for the BGN coverage, we add a MESH port to on the RB433AH and it work under the AP Bridge mode. The RB433 in the bus will be set to be the Station mode which connects to the video recorder.
But something must be solved first:
First, we find the BGN’s connection is not quite stable, it can’t reach the full speed.
Second, due to the bus’s mobility, it will roam numerous base stations, the switch time keeps at 2-5 seconds which is unacceptable. I want to know is there any suitable method to satisfy the BGN coverage with the MESH manner? (We have tried to set both AN and BGN to be MESH WDS, but is seems we can’t put the data to the backbone network, the data go to the BGN’s MESH directly. )
So, Who give me a proposal is never the problem? Any suggestion will be appreciated !
TKS!
I have built a MESH network similar to the one you have described.
We have not seen any of the issues you are worried about. Cpe will roam between the ap’s in the mesh without any major delays.
I have very simple set up which however requires similar set up. I would appreciate if someone could help me with the set up.
my main problem is the speed in which the handover between the access points occurs.
I have a vehicle which travels between access points, on the vehicle is a camera and the video feed is used to control the vehicle.
It is crucial that the signal is very quickly handed over between the access-points.
This is a new installation and I’m totally free in the selection and configuration of hardware.
Please see attached PDF drawing

Ok. Have you tested the client handover between the access points or are you worried if the handover speed is not going to be fast enough and the system is not built yet ?
Make sure all ap’s in the mesh are on the same frequency and have the same ssid.
My clients switch between ap’s very fast and drop (max) 1 ping packet when roaming between ap’s in the mesh.
I will help you with this setup if you like.
This system is not build jet. I can use any hardware and cost is not the deciding factor (with in reason). I can use 2 radios on the vehicle if needed. I would relay appreciate your help with this project. I have build a number of wireless networks but none had the requirement of seamless hand over.
Thank you

I am just about to rollout a new network, and was thinking of configuring the the entire system of AP’s as a WDS mesh, how large is your mesh environment?
your comments would be valuable
Hi, most of my network is configured as a fully automatic multihomed ospf / bgp routed network. We have over 200 ap’s and backhaul in this type of config. I would have several areas within this infrastructure that are operating in a MESH config. I would not recommend committing to a 100% dynamic mesh config as you can lose some flexability. The dual frequency mesh solution is excellent in the right circumstances (coverage of a village for example where no high points are available) but I would not use it everywhere. It is just a tool to be used when necessary and where you need efficiency that is not found in a standard wds that relies on spanning tree to avoid loops. MESH does not need STP and is as a result more efficient.
Hope this helps
Is MESH work with Nstreme?
Is MESH work with Nstreme?
I do not see why not, although I have not used NStream in a production MESH config envirn, if all devices in the MESH were Nstream enabled then it should work. Be aware that NStream is a MikroTik proprierty protocol and will only connect to other MikroTik NStream enabled equipment.
Think of MESH as a way to do WDS but without the inefficient Rapid Spanning Tree loop requirement and it is better at working out alternative paths across the network.
Without Nstreme, AP WDS connect to other AP WDS.
But Nstreme AP WDS not connect to other Nstreme AP WDS
How in this case organize MESH network with many nodes?
Scheme without Nstreme not so interesting on the score of small speed, capacity and problems with hide nodes.
Hello,
I am very interested in what I read about how you all use the Mikrotik Mesh solution and about your experiance with handover between APs.
Can you let me know how you configured the Mesh, OSPF and the multi-frequency roaming network (DHCP, IP-Range etc.) with 2,4GHz for Clients and the 5GHz for the mesh? Please point me in the right direction!
I need to install a WLAN services in a hotel with 11 floors (28m x 20m), a second building with 3 floors (20m x 100m).
The two building will be connected via a 5MHz bridge, or via an existing cable.
The WLAN service is not meant for customers (yet), but for the internal personal using wlan for a software they use to facilitate needs in the hotel.
The idea is to have a continuous (through-going) network to be able to roam from one hotspot to another without interruption or packet loss. VoIP is NOT the goal, but an uninterrupted experiance using the software.
As we cannot use the preexisting network within the hotel we would have to rewire the hotel to connect the hotspots, and I would like to keep wiring to a minimum.
My ideas (first thoughts):
-
Put a switch on each floor, connect standard stations (picostation etc.) via cable and set all routers on same SSID on different channels.
-
Put a switch on each (second) floor, connect one Mikrotik-Router to it and use others in a mesh to cover the floors.
-
Put a Switch on the top and bottom floor as “mesh exit points” and use Mikrotiks on the floors as needed. The mesh is used to transport data trough the two wired access points to the server/internet. The Mikrotiks would have two wireless cards each:
2,4GHz for clients and 5GHz for backhault-mesh. -
Use Mikrotik Wlan-Routers on each floor, connected via a 5MHz connection to replace cabling between the floors. Use WDS with Picostations or other Mikrotik Routers to span the hotspot on the floors. Mikrotik’s WDS mesh solution could be used to extend the range of the wlan network on the floors and maybe between floors.
More questions: -
Is there any experiance wow many hops a Miktrotik-Mesh can support without loosing to much bandwidth (and how many devices are supported)?
-
Could I use the Mikrotik-Routers in the ceiling to cover two floors? Is it feasible to just install Routers every second floor?
I am very courious about your experiance, your ideas and your warnings.
Thanks for relpying in advance!
Robert
