set up wireless 360 using 3 sector Antennas

RouterOS Wireless Networking

Please help me set up wireless 360 using 3 MikrotIK RB4I1 Radios,3 wireless cards,3 sector 120 antennas.

2

What do you need help with exactly?

3

My problem is how to configure the three mikrotik RB411AH to allow clients to connect to any of the three sector antennas,without ip conflicts.Different ssid will be used for the radios.

4

How many clients are you expecting to connect to this system at any given time? How much bandwidth are you going to provide to each client?

5

Why do you want different SSID on each sector if you want the clients to be able to connect to each?

Bridge them, set one AP as the DHCP server.

6

Hi CBrown,i am expecting about 60clients to connect,20 clients per sector,with download speed up to 1Mbps and upload speeds up to 256kbps per client.

7

Hi Oldman,most of my clients use cpe to connect to the radio on a sector antenna with line of sight,The difference ssid will let me know which sector they are connected to,and also limit interference.

8

It’s not going to help with interference. Is your internet feed coming in via wireless do you have a wired connection at the AP?

Hi,

configure the rb411ahs as bridges and do dhcp on a rb1100ah this rb411ahs are connected to.
Use the same ssid. Control the cpe/sector assignment with accesslists.

Hi C.Brown.Internet feed is coming via a ADSL moderm to a Edimax Broadband Router,and the cables from the three radios are connected to the Edimax broadband router for the internet.

11

Hi Stefan,I do not have RB1100ah,instead i have Edimax Broadband Router where the radios RB411ah pick the internet.The IP address are
Radio 1.-----192.168.0.250/24 192.168.0.0 ether1
192.168.3.254/24 192.168.3.0 wlan1

Radio2-------192.168.0.251/24 192.168.0.0 ether1
192.168.5.254/24 192.168.5.0 wlan1

Radio3--------192.168.0.252/24 192.168.0.0 ether1
192.168.6.254/24 192.168.6.0 wlan1


Please do u find anything wrong with this settings?

You will have problems if you jump one CPE to another sector. They tend to hold on to their IP address.

13

I will not juimp from one CPE to another sector,every CPE will be connected permanently to one sector,with the ssid.Please comment on the radio IP and wlan address,they include network address.

14

I would build a bridge with ether1 and wlan1 and assign one IP to this bridge.

15

Hi Veteran,Please comment on my ether1 and wlan1 address,how do i bridge ether1 and wlan1 and assign one IP to this bridge,could you please give me an example.Should i do it on all the three radios

Hi,

http://wiki.mikrotik.com/wiki/Manual:Interface/Bridge#Bridge_Interface_Setup

Just create a bridge, add the 2 interfaces (wlan1,ether1) to it and then add the ip to the new bridge interface.
A router connected to all three sectors ethernet interfaces can see the cpes connected to the wlan sides of
all sectors and give ips to them.
When it is a mt router you can bridge or switch all sectors together so a you can use a single dhcp-server/iprange
for cpes connected to all sectors.
