New Mimosa B24 radioline in action!

New 24GHz radio from Mimosa Networks

Mimosa Networks met the expectations of its customers in 2018 by presenting their latest solution operating at 24GHz.

Mimosa B24, because that's what the latest radio line operating at 24GHz is called. It supports the TDMA and TDMA-FD protocols and aims to revolutionize the industry while meeting the needs of customers in many industries.

It is also noteworthy that the B24 consumes only 19.5W of power, and is therefore perfectly suited for power supply via batteries and solar panels, and has an SFP port that is probably compatible with all available cartridges on the market.

Taking the tiny power consumption into account, we decided to use EXTRALINK 12 V 7,2 AH batteries connected in series to get 48 V.

You can't forget the professional mounting bracket, which enables very precise positioning of the antennas - and this is one of the most important stages in the installation of each link, especially in the case of radio links.

Mimosa B24 works well in urban agglomerations (and not only) because it remains very stable in the less noisy 24GHz band and you can definitely set up a link over a much longer distance than in the 60/70/80 GHz bands, and additionally 24GHz is not so susceptible to weather conditions (rain/snow).

Of course, like other Mimosa products, the B24 radioline is also equipped with GPS synchronization so that the devices can work on the same channel. GPS synchronization allows up to eight links in the same location.

Theoretically, with B24, a connection of up to 3 km can be established, but that is the upper limit.

With this information about the latest Mimosa radio line, we can move on to the practical part, which is what we like most -> performance tests.

Traditionally, we have prepared a testing setup.

To check performance, we used both the built-in Mimosa mechanism, the indispensable iperf tool, and the MicroTik Bandwidth Test. We tested both the TCP and UDP protocols.

The link was set up at a distance of about 1.5 km, and after adjusting (it took a while) the antennas properly we managed to get a signal of -57dbm.

Let's go to our test results. Mimosa B24 was tested in 3 stages:

TEST1 - using the built-in Mimosa tool and UDP protocol

TEST2 - using the MicroTick BTest tool and the TCP and UDP protocols

TEST3 - using a very graceful iperf tool (1.5, 10 TCP steams)

As you can see, the results are very satisfactory. We have achieved a throughput of over 1300Mbits with a very stable connection.

Radio line B24 from Mimosa clearly deserves the attention of anyone who needs a stable and very efficient link for e.g. a business client or for a backup link.

You know, I think that at this price (650usd) it is impossible to buy such an efficient 24GHz radio line, and given the much lower susceptibility to weather conditions than in the 60/70/80GHz bands, I recommend this solution to every ISP.
