Bullet Titanium M2 EOL vs Bullet Dual Band AC IP67 replacement

We have about 300  Bullet Titanium M2 which are end of Life.    We use them offshore in international waters to communicate between  vessels.   It requires omni antennas.  We would get a range of 10Km and speed was not that important.   

I noted that the replacement Bullet Dual Band AC IP67 at 2.4MHz can only output 22db  vs 28db of the Titanium M2. 

WIith only 22db I dought that the Bullet AC can do 10Km with the same antennas.   Or do they have a mode with slower speed were I can set them to 28db. Note: 28db is legal in international waters. 

Will the new Bullets DB AC perform the same or better regarding range or will they be worse?

Else do you have a better replacement.......or did Ubiquity drop the ball?

You have a unique application and surprisingly good

results with 10km aboard vessels in open water. For

your application, his new Bullet likely won't do.

 

That 6dBm deficit in rf output can't be made up by

an antenna; an omni antenna can only have low

gain unless its vertical beamwidth is drastically limited.

 

You may find similar results with Rocket M2 or with

Rocket AC radios--also with the advantage of MIMO.

But you may need to search for a compatible antenna,

because the Ubiquiti omni has an electrical down-tilt

which would not be compatible with your application.

Cost will be higher too.

 

For this low-speed application, perhaps a data radio

of some sort would work better.   Dave

Re: Bullet Titanium M2 EOL vs Bullet Dual Band AC IP67 replacement

Thanks for the quick response. The Rocket M2 Titanium are already EOL and the rest of Rocket M2 might soon follow.  Am I betting on a dead horse?  I already getting burned with the Bullet EOL.

 

The Rocket AC  only have 5Ghz which will not give us the range.  That would leave us with the Rocket Prism AC.  I am not sure if they can do point to mulipoint with repeaters as the Bullets did? The seem to be for point to point.

The Rocket antennas vertical beam at 12deg is too narrow since vessels rock and roll in the water. The minimum vertical beam is 18 degrees.  I am looking for alternate antennas but so far could not find anything suitable at LCom.  I could go for custom made antennas?

Data radios are not a solution. It has to be be a IP WiFi radio.

 

I might have to move to Mikrotik as they have some more choices. I would rather stay with Ubiquity if they have a solution.

As it stands today I am not aware of any plans to EOL the Rocket M2.

But it's not unfair to state the obvious: all the AirMax

'M' series radios are legacy, with a very old design.

 

I'm not sure what 'more choices' amounts to; this seems

on the surface to be an impossible task, and there are

no antennas that have both huge beamwidths and high

gain. You haven't described the application, or even the

data rates needed.    Dave
