What about 133+R52 +15dBi Omni [Coverage]?

Thu Nov 22, 2007 8:14 pm

Hi

If I use RB133 with one R52 wlan and one 15 dbi omni antenna with hotspot enabled..

How much coverage will I get?

I want 12km max (each direction)

What about stayability?

That's a loaded question which there is no good answer for.... In a wide open area where there are no trees, hills, or buildings in the way and there is no interference... yes, it is possible... In a big city or forest, probably not chance of it. Also depends on the clients' transmit power, antenna, and receive sensitivity. I'd at least upgrade to a high powered card for long range like that.

That's the best I can do with the limited info you gave.

in a perfect theoretical situation, sure, it'll work just great.

Realisticly, 10.5 dBi pushing 200mw with a 24dBi grid for a client got me 5 miles on a test shot. With MT, it would have been a stable signal. It still would have been at the absolute edge of stability, but it would have worked.

Thank's jcremin

It's in a small city (12km between city's 2 sides).

The tower will be higher than any building in the area and no trees.

The interference is low, most of detected wifi net's are adsl modems.

I would like to upgrade. What do U suggest?

I'd suggest to go up with a test system and just check the noise floors to see what what they say just to make sure. It's better than doing a huge install just to find out it doesn't work.

If it were me, I'd probably go with an XR2. If not for the higher output and good receive sensitivity, because it has the extra protection against static that many have reported from their omni's....

And in response to the "omni's suck" comment, my opinion is they work as good as any sector antenna if you don't have noise or too many customers on one antenna. Gain is gain and if it works, it doesn't suck.

That's a good idea.

I made a test with a swivel antenna that came with the RB. The noise floor is -100

I'm going to upgrade but as I already have the R52 I want to see if it is possible. My aim now is 4km (all directions) max.

I will not have more than 15 customers.

Thank's jcremin

I did a mistake of replacing 3x120deg sectors (indivdually fed with 2xr52 and a XR2 on rb532) with an 15db omni antenna and im desperate right now :(

if you want peace of mind, good quality signal and stability, do NOT ever go for an omni.. pay a few more bucks and go for individually feeded sectors.... I did more than 100 customers in 3 weeks time with that setup, all NearLOS....

You did the right way doush. But the omni's are cheaper, more available & easy to install.
I have an omni. I'd like to try it first.

Thank you :)
