AT&T in Oakland causes interference, has to shut down Cellular 850 MHz

AT&T's Cellular 850 MHz A block network in Oakland has been causing interference with public safety's newly rebanded (courtesy of Sprint) 800 MHz radio system. As a result, AT&T has temporarily shut down at least part of its Cellular 850 MHz operations in the city.

Additionally, this is what I posted at Ars Technica:

 

Ars' and other articles seem to indicate (but are not entirely clear) that AT&T has temporarily shut down its 2G GSM 850 airlink in Oakland but has left up its 3G W-CDMA 850 airlink. If this is correct and it has halted the public safety interference issues, then AT&T may very well be at fault. Narrowband GSM channels at various frequencies within ATT's Cellular 850 MHz A block license could be creating intermodulation products that are falling within public safety's 800 MHz spectrum.

Chances are it might not be AT&T which is the cause of the interference, it might be the crappy radio system they bought. Harris radios aren't the best.

    • Curious as to how SCP works with it regarding NSA, particularly in markets with n41 BW=100 and second channel.

    • T-Mobile eNB 879491/879493/879494 on the keep site map is located at 40.77536940167816, -73.92011957697034. Sprint eNB 5762 is now T-Mobile eNB 306271. Located at 40.582064139078206, -74.16175767702059 Weirdly both of the new Sprint conversions that have been found in Staten Island (eNB 306271 and eNB 326459) were sites I visited earlier this summer but neither of them were broadcasting the keep PLMN at the time. In fact, Sprint eNB 5762 was completely offline when I visited. I suspected both sites were keep sites based on their location relative to neighboring T-Mobile sites so I was surprised when I didn't spot 312-250 coming from them. Glad to see T-Mobile still kept them. Also T-Mobile isn't done with non-conversion new builds in the city. T-Mobile eNB 894075 is a brand new site added this summer on Rockefeller University's campus in Manhattan. It gives me hope for neighborhoods like Red Hook and Williamsburg that desperately need sites along the waterfront.
    • Nearly every site I encountered in the Bronx was running N41 SA. Consistent pings in the low teens and speeds were actually great. Sprint eNB 9294 got converted but isn't live yet. Location: 40.83091697219704, -73.8178106151994   Sprint eNB unknown, now T-Mobile eNB 310677 Location:40.880070855974395, -73.83644046611454   Sprint eNB Unknown, now T-Mobile eNB 894775. Bonus speed test with 2CA and N41 SA. Location: 40.8989406640668, -73.84564472722599   Sprint eNB Unknown, now T-Mobile eNB 894854. 40.86220687471859, -73.86242513896488
