caspar347 Posted September 30, 2014 Share Posted September 30, 2014 I was leaving school today and noticed hoist ropes dangling off of the tower on our school property. I ran over and found a crew putting up 2 new antennas and 1 RRU per sector on the AT&T rack. This struck me as odd because I believe the current equipment on the tower is fully B17 and B4 LTE capable. The new RRUs say RRUS12 B4 and the antennas both have two frequency sets (basically all of 700+CLR and AWS+PCS and WCS, apparently) despite being different heights. The tech I talked to seemed to know what he was doing (a rare occurrence) and said that one of the antennas was specifically for LTE. The taller antennas also have, among other things, "WCS" written on them in marker. http://m.imgur.com/a/W4XXm Anyone have any idea what is happening? 1 Quote Link to comment Share on other sites More sharing options...

tybo31316 Posted September 30, 2014 Share Posted September 30, 2014 Why does AT$T more equipment on their sites than any other carrier? I know that more is not better but what's the reasoning behind it? Sent from my Nexus 7 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Destroyallcubes Posted September 30, 2014 Share Posted September 30, 2014 Those look just like these: New ATT sites Here are 4 panel sectors, with only 2 running. Most likely not running WCS yet. But have the capabilities of so. 2 Quote Link to comment Share on other sites More sharing options...
jroepcke51 Posted September 30, 2014 Share Posted September 30, 2014 Does T have that much AWS nationwide? I know that WCS is really there only expansion band (outside of the impending auctions). Quote Link to comment Share on other sites More sharing options...
lilotimz Posted September 30, 2014 Share Posted September 30, 2014 Does T have that much AWS nationwide? I know that WCS is really there only expansion band (outside of the impending auctions). It's either aws or pcs for their second lte carrier. Market by market type of stuff. Sent from my Nexus 5 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Dkoellerwx Posted September 30, 2014 Share Posted September 30, 2014 Band 30 WCS 2300 MHz. I guess it is happening. AJ Looks like the antennas posted in the East Kentucky thread a couple weeks ago. Quote Link to comment Share on other sites More sharing options...
WiWavelength Posted September 30, 2014 Share Posted September 30, 2014 The photographed antenna panel does seem to represent an AT&T infrastructure bandwidth expansion. Previous antennas supported Lower 700 MHz (band 17) through AWS-1 1700+2100 MHz (band 4). This antenna supports Lower 700 MHz (band 12/17) and Cellular 850 MHz (band 5) via its low frequency port, as well as PCS 1900 MHz (band 2), AWS-1 1700+2100 MHz (band 4), and WCS 2300 MHz (band 30) via its mid/high frequency ports. And it does appear to have dual mid/high frequency ports. Antenna gurus, can you corroborate? AJ 1 Quote Link to comment Share on other sites More sharing options...
EvanA Posted September 30, 2014 Share Posted September 30, 2014 What RRU does AT&T use now? RRUS 12 B4 only support band 2, 4, and 5 so no WCS deployment just yet. Quote Link to comment Share on other sites More sharing options...

AJ I think the panels are still on the ground and I can get more photos of specific stuff tomorrow if there's anything in particular we need pics of. Like the RRUS12. Also, I think I got pics of both antenna bottoms. I'll check tomorrow. Quote Link to comment Share on other sites More sharing options...

Most sites I've seen with these new installs have 4 panels two unused. My guess is the will have WCS dedicated RRUS and just use the unused panels for WCS and extra LTE carriers for b2,b5, and b4.

It is flexible for whatever holdings they have for that market. The question is now, is this set up necessary for them? Quote Link to comment Share on other sites More sharing options...

TheForce627 Posted October 1, 2014 Share Posted October 1, 2014 Here in the DC area I see ATT sites with 4 antennas. Usually two large ones and two smaller ones. Haven't seen any that are all the same size yet. Quote Link to comment Share on other sites More sharing options...
bigmachine Posted October 1, 2014 Share Posted October 1, 2014 In Los Angeles AT&T has mostly 4 panel installations. Verizon is a hodge podge of everything. It looks like they picked up panels from garage sales around town. 2 Quote Link to comment Share on other sites More sharing options...
caspar347 Posted October 1, 2014 Author Share Posted October 1, 2014 Just took more pics that I'll upload later. The short and long antennas have the exact same port layouts and numbers. The tech told me that these would replace two of the three antennas per sector on the tower. Also: the tech claimed that the ALU equipment around here sucks and the Ericsson stuff is better after I mentioned Sprint using Ericsson elsewhere in the US. I chuckled a bit and said "whatever." Is this the first positive review of Ericsson gear ever? 1 Quote Link to comment Share on other sites More sharing options...
Jeffrey_J Posted October 1, 2014 Share Posted October 1, 2014 Email from ARRL about ATT WCS band. In comments filed in response to an AT&T Mobility Petition for RuleMaking seeking a new air-to-ground communications system on 2.3 GHzWireless Communications Service (WCS) spectrum, the ARRL has onceagain asked the FCC to elevate the Amateur Service allocation at2300 to 2305 MHz from secondary to primary. The Petition (RM-11731)asked the Commission to authorize an LTE-based in-flightconnectivity service in the WCS "C" and "D" blocks (2305-2315 MHzand 2350-2360 MHz, respectively) for airlines and airlinepassengers. AT&T has asserted that restrictions on out-of-bandemission and power limits to protect adjacent-band users make theuse of the C and D blocks problematic. The wireless provider askedthe FCC for rule changes to permit deployment of its service "usingcurrently fallow spectrum" while also "preserving adequateinterference protection to users of adjacent bands.""Notwithstanding this broad and nebulous claim, there is no showinganywhere in the four corners of the Petition that the proposed rulechanges would permit any continued Amateur Radio operations on asecondary basis in the shared A block (2305-2310 MHz)," the ARRLcommented on September 22. More to the point, the League said, thereis no showing in the Petition that Amateur Radio operations in theadjacent 2300-2350 MHz band would be protected from increasedout-of-band emissions, if the FCC were to implement the changesrequested.The League asserted in its comments that the FCC has, to date,"failed to protect Amateur Radio operations at 2300-2305 MHz fromWCS out-of-band emissions." The ARRL said the band is "regularly andsubstantially utilized by radio amateurs" for weak-signal,long-distance communication and, only by circumstances - a lack of aprimary occupant - has it been able to enjoy that segment as a defacto primary user."The Commission's rules are quite clear that WCS licensees enjoy noentitlement to disrupt adjacent-band radio service operations," theARRL commented. But, the League pointed out, previous FCC actions toexpand mobile broadband devices left 2300-2305 MHz vulnerable toincreased out-of-band interference that would be difficult orimpossible to mitigate. The ARRL said amateur stations operating inthe 2300-2305 MHz band would be unable to avoid interference from ATand T Mobility's proposed system, and that the FCC has refused toclarify the obligation of WCS mobile providers to avoid interferenceto Amateur Radio operations there.The ARRL objected to what it called the FCC's "practice of makingallocation decisions which place incompatible uses in closeproximity to amateur stations and then place on the amateurlicensees the burden of avoiding the interference.""It is obvious that the result of the AT&T Petition will be avirtual preclusion of amateur access to the 2305-2310 MHz segment,"the ARRL's comments continued. "A ubiquitous air-to-ground systemwhich operates at and above 2305 MHz will clearly render thesecondary allocation status of that segment a virtual nullity."The ARRL asked the FCC to recognize Amateur Radio's "de factoprimary status" at 2300-2305 MHz and to elevate that segment fromsecondary to primary for amateurs. It further called on theCommission to "clarify the obligation of WCS licensees in allcontexts to protect the adjacent-band Amateur Service operations at2300-2305 MHz from harmful interference." Finally, the Leaguerequested that AT&T provide "a complete technical compatibilityshowing and interference analysis" that would demonstratecompatibility between its proposed service and amateur operations at2300-2305 MHz.

gnoj Posted October 1, 2014 Share Posted October 1, 2014 In Los Angeles AT&T has mostly 4 panel installations. Verizon is a hodge podge of everything. It looks like they picked up panels from garage sales around town. Sprint's racks will also fill up eventually with their own sort of hodge podge. In addition to the current 800/1900 and B41 antennas, they'll also have 600 MHz + any equipment related to a spectrum hosting deal with Dish or a CCA partner. So it's important for them not to put off taking down the legacy antennas for too long. Also, does this mean the AT&T work stoppage is coming to an end?
