What is the record for point to multi point links

Hi,

Was just checking out some point to point records. What would point to multi point link record be?

Number of clients or distance?

What frequency?

Hi,

Looking distance record

Interested because I would like to see if I can break the record.

We just tested a link at 10 miles, just need to finalize the installation. Signal was a steady -79, ccq better than 80%.

I asked a similar question a few months back, one guy says he had a 12dBi omni with a 24dBi client at +22 miles. Has to be a clear shot, to say the least.

Hi, I have a link up for point to multipoint, 22Miles(35km) on two clients, and I think if we get a client at 40km we will still have quit good signal.

We have quite an advantage in our area, as we are based in the Kalahari, with little to no interference. Only problem all our high sites have to be made (towers), as there are no natural high hills or mountains.

Would be interesting to know if it is a record or not.

I had a 9dbi home made omni that was working at a distance of 45km(28Miles) intermittently, stable at night.
The omni was at 8m above ground level and the client was 24dbi omni with 200mW senao client. Omni was not tweaked at all, might bet better performance from it, but can’t tweak it now as it is in operation on repeater station, at a site that lies just outside line of site.

Most our sites are at 1000m asl with no moutains or buildings, very few large trees.

Could someone let me know what the theoretical distance I could get using 17dbi 120deg base with 200mW cards, and 24dbi clients with 200mW cards. I think at some point the earth curvature would start playing a role, just not sure at which point. The these long range links we have 30m Tower at base station and 20m masts for antenna’s at clients.

Thanks, for the reply.

Hi is the link you posted not for Point to Point Link?

I actually asked for Point to Multipoint.

I have no interest in breaking that record, don’t have the means $$ to get to a location where it is possible.

Very interested what the current point to multipoint record would be, and how many long distance clients actually connect to the base station, without a repeater.

There is nothing magical about point to multipoint vs. point to point. It’s all the same. Antenna gain + radio power - distance.

Technically you could use a 30db dish on the AP side and have 100 clients at 80 miles with 24db grids… of course they would all have to be within 5 degrees beamwidth, but it would still be point to multipoint.

We have clients out to about 15 miles p2mp, in a relatively non-optimum environment. Southeast kansas. Kinda hilly, not too bad. Fair bit of trees.
