Can the modem (CODA-4680) be setup sideways (i.e. horizontally)?

EVS · June 2023

I did not have enough clearance to set up the modem upright (vertical), so I set it up sideways (horizontally) and lifted it a bit over 1/2 inch to allow for airflow.

I wonder if this is OK and whether it makes any difference in range and/or performance.

Thanks!

Hi @EVS

Please check on the temperature, that it is the most important thing, if there is enough air flow you will not have any problems

Good idea to add blocks for air flow. If there are ventilation holes on the top and bottom only, the position might affect the airflow, but it looks like there are some on the sides.

In theory, it is possible that the antennas will provide a more consistent coverage in the vertical position, but I think it is unlikely. They are probably mostly omnidirectional.

It will definitely not blow up. Maybe an occasional dusting and it should be fine.

Temperature is OK, it is not getting hot at all.

For functionality, the most important is the temperature. There are no mechanical components inside, so the positioning doesn't matter much.

As for the antenna, its performance depends on its placement. If you don't have any WiFi signal problems, you're okay. However, these issues can also occur in a vertical position. Sometimes, adjusting the position slightly can affect the signal.

Yes........................

I don't think it really matters... any mention of restrictions in the owner manual?

I don't think it matters either, but I could not find anything in the manual.

It does have ventilation holes on one if the sides as well. When sitting upright (vertical) it only does not have holes on the bottom and on the back.

I turned it so that is sits vertically and the signal strength at the back of the house improved by about 3-4 dBm.

So we will see how it performs on Teams meetings.

Thanks everyone!
