RRU Questions


Recommended Posts

1) How far away have we seen RRUs from the panels? Curious as some of the sites I've visited appear to have boxes on the tower grid itself and not mounted on the back of the panels as other confirmed LTE sites have. Will have to revisit with binoculars to confirm via cabling (making sure they are radios and not just all-weather enclosures), but I was curious if Sprint was using a standard OEM model of panels+RRUs.

 

2) Do any other carriers currently use RRUs? When identifying Sprint vs Tmo/ATT/Vz on a tower, are RRUs a dead-giveaway of Sprint LTE or do other carriers/technologies use them as well?

 

Answers might be FAQ material...

T-Mobile and AT&T currently use RRU's as well.

AT&T already uses RRU, tmobile is also using(starting) with its new network upgrades. Depending on tower and partner for sprint the RRU can be mounted on the tower structure and not just behind the panel. The RRU purpose is to move radio from ground like older tower setup to the tower itself near antenna. Benefit is less power loss and better/stronger signals

This is a site done by Ericsson sub contractors:

From what I've seen they are always directly behind the large NV panel.

 

I think there are some of Alca-Lu and Samsung work in the gallery here.

 

Edit- This video here gives you a good look at the RRUs.

Good stuff. Missed those threads apparently. Digiblur: I saw those pics when he first posted them on G+ (taken in this area), but didn't have the backstory you provided here. Explains a lot, thanks.

 

Need to remember to keep the telephoto with me so I can look closer.

    • Sent an immediate diagnostic report
    • Rolling out a new beta release now with some minor adjustments and additional logging. Please log out of the app (or remove your session(s) from the website if the app is not providing the log out option) and try to log in again. If you experience an issue, please submit a diagnostic report immediately after your attempt. Logs only capture a limited amount of information, and sometimes a delay causes the useful information to already be overwritten. I also sent an e-mail to the beta crew offering a faster way to receive beta updates, please let me know if you have any questions.
    • what differences? My son is thinking of going from the 21 ultra to the pixel pro... Yea, nay??
    • I just hope it doesnt make me reset my PW to log in every 5th time.. Sprints side has been wonky for a while. The 1 year I went to Tmo, I did like their online stuff 3-1 vs sprint Having a biz account might be making it troublesome, but I don't know why, everything in there is pretty straight forward. I heard it "might" be the financing issues on the sprint side.  I do know if I want to upgrade any of the lines, it still has to go through sprint, if I try on the Tmo side itll force me to pay off the few I have, vs it just bringing them over.
    • Just switched to the S22 Ultra from the Pixel 7 Pro. Love this beast!!
