Better wireless throughput with RB600 or RB433AH?

RouterOS Wireless Networking

Hi,


Do you think it’s better to use RB600 or RB433AH to make a Dual NSTREME link?


Thanks,

Both boards provide enough ‘horsepower’ to top out a Nstreme2 wireless link.

If you require gigabit routing via ethernet or true 802.3af PoE support your only choice is the RB600.
If you are going to using lots of queue/mangle/firewall rules go for the RB433AH as its processor is faster.
Both boards provide enough power to the M-PCI cards for multiple high power cads (ie. 2 x XR2/XR5), just make sure you use power supplies that can provide the necessary power (for RB600A → 48V x 1A, for RB433AH → 24V x 2A)
My personal feeling is the RB433 layout is going to be around longer so drop in replacements may be easier to get in the future

Cheers

Ok! thanks!

Do you know how fast could be my wireless link with 2 radios?


Thanks,

it highly depends on the outside influences on the link:

    • other ppl using that frequency and polarization
  • LOS or NLOS
  • quality of antennas

that is why, best thing to do, get some gear up and test for frequency usage, interference, etc.

Hi Janisk,


I need the max speed.. I know this other influences, but in the best cases?

Can I get 50+50Mbps with dual nstreme?

thanks,

In my lab I did extensive testing on the ‘theoretical’ ‘real world’ performance.

What is ‘theoretical’ ‘real world’ performance, simply put its the maximum speed of RouterOS on 802.11a,b,g link with absolutely minimal interference, perfect LOS and perfect link quality, yet still actually using the real product.

My internal tests showed bandwidth’s of ~30-35 Mbps half-duplex going through a single link on 20 MHz channels in both 802.11a and 802.11g

ie.
computer → RB600A —wireless— RB600A → computer

When moving to Nstreme Dual I was able to achieve ~35 Mbps full-duplex
When moving to a full-duplex routing with Nstreme I was able to achieve ~30-35 Mbps full-duplex (this was expected as both radios were required to Tx and Rx)

I didn’t do alot of testing with the turbo modes, but I have achieved >50 Mbps half-duplex in the lab, but I would seriously doubt continuous operation of >50 Mbps full-duplex. The amount of spectrum being used and the affect that a little bit of noise/interference in the vicinity of the link can have on the throughput would be the major reasons. However it is technically possible.

I make a 140 Mbps link with 4x RB333. 2 links of 70 Mbps half duplex (turbo mode+nstreme) but I need to make it with one RB.. and I don’t know if it is possible.

I make the 70+70 with a RB600A in both sides cabling the 2xRB333..



140Mbps

Will you facing the limitation on your ethernet part (due to 100Mbps real user data rate) only but they wireless support 140Mbps???

Hi!


ethernet ports of RB600A are 1Gbps.
