PtMP- 1.5 km- 1 AP and 3 stations over a lake

Hello

 

Please note that I'm almost new to all this.

 

I have to send an internet signal to 3 stations over a lake. The distance is about 1.5 km. From the AP, the 3 can be reached within a 30-40 degrees angle.

 

I now have 2 NBE-5AC-Gen2 (1 AP and 1 station) in a PtP configuration working over the lake. Therefore I need to add 2 more stations.

 

Can the AP still be a NBE-5AC-Gen2 in a PtMP configuration with that narrow 30 degrees angle ? Would it be better to use a LiteBeam, or something else ?

 

Thanks to provide me with some guidances.

 

Gaston

There's no need at all. Stick with what you have.   Dave

You don't show an aerial photo or a map, but it's

likely that two NBE-5AC-19 radios will do. Review

the antenna pattern:

Be careful when redistributing Internet service. Most

provider terms of service do not permit this, or any

kind of 'sharing'. If discovered, you could lose service.   Dave

Thanks Dave

 

I attached 1 image to this post. As you can see, the distance is less than 1 mile from the AP, and the stations are quite closed one to another. There is no internet provider on that side of the lake.

 

I already have 2 NBE-5AC-Gen2 installed in a PtP configuration. My intention was to install 2 more stations in a PtMP to complete the configuration. 

 

For the AP, I know that I have to select a device with the correct coverage angle, not more. The question that I'm unqualified to answer is: on the AP side, could I install another NBE-5AC-Gen2 (in fact it is already there in a PtP configuration) or install something else if the coverage in a PtMP is not adequate ?

 

Thanks again.

 

Gaston

"PS": using the AirLink calculator, when choosing the antenna gain 19 dBm, I'm proposed the NanoBeam for the stations. 

For the AP, I'm never proposed the NanoBeam. When selecting 23dBm, I'm proposed the Gen2 LiteBeam

It seems you have already discovered what works,

because you have a link in place. If you're not

convinced, test with what you have.

 

Place your slave radio at S1; turn the master radio

toward the right until S1 has a slightly reduced

signal, then turn it back a bit. without moving the

master, place your slave at S3 and determine if the

signal is adequate. If it is, of course S2 will be fine.    Dave

It's very smart Dave.Smiley Happy  Thanks.

 

At first glance, would you see any adverse effects of using the LiteBeam (Gen 2) on the AP side (except that the site owner will find it too big, of course...) ?
