AT&T Band 30 shrinking from 10mHz to 5mHz Channel

**mdob07** · 09-06-2018, 09:43 PM

I noticed today that all band 30 LTE in the Louisville, KY area has changed from a 10MHz channel to a 5MHz channel. Has anybody else seen this or know why it is happening? Every band 30 site I connected to today has been changed. Band 30 is still being deployed here, sites that didn't previously have it are getting it along with the band 14/66 upgrades. I searched for existing threads about this but didn't find anything. If this discussion is happening already in another thread feel free to close this one and link to that thread.

This was happening here in NYC for a while on some sites. They are all back to 10mhz channels now though. It had to do with Sirius XM interference. Not sure it's related to what's happening by you though.

What Joey said — it’s related to interference between AT&T and Sirius XM in the 2.3 GHz band. I’ve been seeing several sites like this, but not to the extent you seem to be seeing. Keep us posted, for sure.

A map of SiriusXM terrestrial repeaters: http://www.dogstarradio.com/sirius_map.php
Looks like there is one repeater in downtown Louisville.

Damn, they have the power cracked on those, 4000 to 5000 watts...

I still don't understand why that's even allowed and cellular towers can only be like 150 watts or something like that. So much for people claiming cell towers give cancer. Lmfao

Now we need to remember that 5g is going to nuke everybody too.. lol. If cell towers had that power they wouldn't need towers everywhere

Yes we would...because your handset is still low power (a few hundred milliwatts) and has to be heard by the site.

After observing for a week or so, I can say all B30 around Louisville and surrounding areas is 5MHz. I took a trip down to Bowling Green KY Saturday for LS fest, and it was also 5MHz there as well as the entire stretch down there where I hit it. Today for work I'm out in the Frankfort and Lexington area, and noticed it jumped back to 10MHz right as I hit Frankfort. Weird...

Another update, it appears that Frankfort and Lexington KY areas were changed to 5x5 last night. I was just out in these same areas yesterday for work and it was still 10x10. I drove through Frankfort and I've been all over Lexington this afternoon, as well as Versailles and Nicholasville KY. All were now 5x5 MHz for band 30.

Are they rolling out fixed broadband by you?
