Sirius/XM Dead Zones

I consistently lose XM reception in Addis LA of all places. The only thing that I can see that would cause interference are 2-3 cell phone towers. Do these towers really cause this effect, or is it the suckiness of Addis?

I think it's T-Mobile's new rollout. Google "tmobile sirius". Interference issues.

Every morning for about 2 seconds.

good info from WSJ article:
Explains the physics. A more recent article says the FCC sided with T-Mobile, so it falls to SiriusXM to come up with a fix.
Regardless, Addis still sucks.

The conflict between Sirius and T-Mobile derives from a quirk of physics, caused by something known by radio engineers as intermodulation. This happens when two airwave frequencies combine to create a third, similar to ocean waves coming together and making a new distinct wave. In this case, two airwave frequencies used by T-Mobile have produced a new frequency inside Sirius radios that is disrupting service.

Yeah in Lafayette around the mall. Dead zone. I thought it had something to do with the time of year.

Dirty little secret about satellite radio (SR) that does require some technical explanation, but this *is* the tech board, so...
Anyway, space-based SR was designed to work with on-channel "ground repeaters" that were represented as mere signal hole-fillers. Existing broadcasters quickly figured out that in reality this was going to turn out to be the other way: a network of ground-based transmitters that used the satellite signal as the hole-filler for users out in Podunklandia.
In other words: a competitor that didn't have the regulatory need for all those expensive local studios and annoying local DJ's**. Remember XM selling itself as the "third radio band"? Established interests said not-so-fast and pushed back against the growth of the ground station network.
So other than the largest cities, you're stuck with the satellite signal that's only a mere 22,000 miles away.
**Not gonna comment on how that's how broadcast radio turned out anyway.
Research for this post turned up an interesting map of "Sirius" ground transmitters. Not sure how current or relevant it is, but I can say that I have seen/touched one of the XM ground stations on top of a tall Atlanta building last year. It was apparently working, but it also did not look like anyone had been around to service it in a while.

I live in Addis and don't have any single loss except with certain channels. 1-40 appear strong but others I lose just crossing the I-10 bridge.

I hit it everyday
