Is a line of sight required or can the units be used in separate rooms with walls between?

Line of sight is required. You will also want to make sure there is no interference with any wifi you may have. I have an Apple Airport Express that has 2 channels. 2.4 GHz and 5GHz. Lately I have had an issue with the 5GHz channel interfering. You want to keep your wifi on the double digits and not triple digits channels. I am currently using channel 44 and it is working fine.

The unit I have transmitted a loud motorboat sound through the speakers when the transmitter and receiver were only 8 feet away from each other and in direct line of sight. It's unusable for me. The "interference" source is not anywhere in my home. I trouble shot everything and eliminated any potential source of interference in my home and the noise through the speakers was severe. I gave up. It's useless to me. And I'm a musician and in the technical industry so I'm somewhat familiar with troubleshooting this stuff...

Hello - I bought one of these units (base station and 3 sensors) for my parents. They live about 800 feet off of a main highway with the base station in the house in an interior hallway and it works fine. They had one 7 years prior to that and it worked fine too. I don't think you have to have the sensor and the station in "sight" of each other as most people have the base station in the interior of their home. Hope this helps - Alan

No it is ment to be placed in an interior wall between two rooms. It brings air from a room that is air conditioned to one that is not.

About 10' maximum with direct line of sight is best. Didn't work through walls for me.

The wall might constrain the setup. It can be overcome by moving both monitors forward. However, the monitors then are closer to your eyes, which might not be what you like them to be.

yes a line of sight one ..... this us a GREAT radio better than thd Bose :)

I have two that are about 50 feet apart and on separate floors. They connect. You will get less reception the more walls you have to go through as well as how thick the walls are. There is no designated distance because of these variables.

from what i know it needs line of sight. it uses Ir. just like a TV you need to point the ir sensor for it to work.

No, but the signal can get interfered with depending on the object. It might cut out a bit. For best sound try not to be in different rooms

We use ours installed in a box. There is no line of sight. (we can't even see it up inside the box of electronics) It works great for us like that, but we are using it from probably less than 5 ft. away.

It doesn't need line of sight to be able to respond, however, it does need to be on the same floor. We live in a three storied house and my wife keys could be anywhere. We have to go to each floor to discover her keys. It has worked well when we needed it.

They need to be right next to each other. They cannot be separated or you will have ghosting.

Have not used my unit that way. But if unit made for one structure I doubt if signal can penetrate one exterior wall to enter the wall of another house. That just my opinion.

If you could only read the instruction booklet provided with the unit, you would know you must leave at least a12 inch perimeter around the unit for proper operation. So, no, you may NOT put the unit up against a wall!

It depends on the ceiling construction, but the range is pretty good. I have two of these in an old plaster house and the receiver unit is completely above the plaster ceiling and they both work anywhere within the room, and anywhere in the adjacent room that is within line of site of the doorway. They do not reliably function through a plaster wall.

The ubiquiti units are point to multipoint, however, we always dedicate a pair to each link. We have a mix of different frequency units to avoid interference from each other and trees, etc.. If you use a bunch of units on the same frequency, you will need to reduce the spectrum for each, which reduces the throughput. The 5GHz units must be direct line of sight. We only have about .1 to .5 mile separation, with 900, 2.4, 3.65 and now 5 GHz links, so not experienced with this unit over longer distance. See other answer about 120 degrees, these units are highly directional.

In my opinion they would have to be very carefully spaced. I am not sure about having any overlapping fields of signal. (call the company)I would not recommend that type of use as these units don't have all the controls that the in-ground systems have.It may work but I would not recommend it but I would call the company. They may have larger control system that don't need wires.
