Backhaul equipment?


Recommended Posts

does anyone know what it looks like or has a picture of what it looks like? Much luf lol

 

There are dozens of different backhaul vendors around the country. Usually 4 or more in each market. Each have different looking boxes. But typically they demark into a non descript gray "telco box." And then the telco box is connected to the RBS unit by a conduit. All pretty non assuming and easy to miss.

What does the fiber run look like? I seen orange pvc coming from tower working its way across town to one of the sprint sites here, looks like they were digging the underground for the runs.

 

It is often orange. Sometimes gray. But it doesn't matter if it ends up buried.

Do they run fiber up to the RRH? I've seen other carriers do this, just curious.

 

Yes. Sprint runs a fiber optic line from the new RBS unit at the base cabinets to the RRU installed next to the panel on the tower. Then coax is used to connect the RRU to the panel. Probably one day the panel/RRU connection may be fiber too. But currently, OEM's are still designing and building units where this final connection piece is coax. But the distances are so short that it doesn't really much matter.

Maybe Sprint might be able to get some tips from this site on how to fix their backhaul. Forget FOC, I get such lousy data service in Tampa I think they're using two cans and a string. This happens repeatedly, but especially every weekday between 4-6 P.M. They must be dumping data for voice because of QoS.

Yes, voice always takes priority over data.

 

That being said, my understanding is that voice on the 1x carriers takes up a pretty small amount of the total backhaul, and seeing as voice doesn't go over EVDO, it's likely the backhaul is simply overburdened for data. But, that's my understanding. I'm sure AJ or Rob will come in and correct me.

 

Also, Tampa is in active deployment, so it's likely only a (relatively) short period of time before your backhaul issues are fixed.

Once the network connection leaves the tower, what happens ? Is there a VPN to a market hub or does it go out to the cloud and straight to Kansas City through a VPN ? Intrested in the learning the back end logistics of how it work ?

It goes to the MSC, which you can determine by clicking on the sites pin, and from there it is routed out to the larger internet. Not sure if a VPN is strictly necessary as they have their own backhaul to the MSC. AFAIK, there is no central NOC in Overland Park/Kansas City, except for the respective MSCs for that market. Perhaps they have some kind of warroom at the campus. Also, this is for data, I do not know the ins and outs of how they route voice. Now Robert and AJ, let us know if that is all wrong.

Yeah from my traceroutes on Sprint's nothing goes through Kansas city for no good reason especially out here on the east coast with major hubs for connections in DC and NY. The connections from each tower are a private point to point connection via metro ethernet/fiber no public internet is involved until the connection reaches through the MSC in your respective area, no VPN's as that as complexity and reliability issues.

Depending on the provider and how many fiber counts. Its pretty thin usally about the thickness of RG-11 Coax cable. That may seem thick but most of that is protection of the fiber its self. Yes the orange pvc is usally the new conduit they use a machine to put it underground than use a rope to pull fiber through.

That's very cool I'll keep an eye once we get a spring thaw here.. We just got 5 more inches of the white crap.. I can't wait for summer, being out doors fishing and all.

    • Just figured out this is a waste of time. US Mobile and Verizon lock the eSim to the emei while T-Mobile only uses it to see that you have a capable phone, like Red Pocket does with physical sims (although RP does keep track of what phone you are using it on with the emei.)  So @Trip was right in this case on liking physical sims.
    • Verizon has a reputation for being frugal with MVNOs. After looking around, I also decided US Mobile was my best option. People have gotten C band on it.  Hoping for esim for my S21 Ultra.  No luck so far.  Red Pocket does not claim Verizon 5g, although they say Soon!(TM).  I do see some 5g with it. Typically MVNOs are deprioritized, thus I am reluctant to claim truly getting top speeds with one.
    • Did some exploring yesterday/last night and didn't find a shred of C-Band, including with my brand new US Mobile SIM. Did find 4CA CBRS but the site seemed backhaul constrained; both that plus 15x15 B2 and band-locked 2/66 got me 190 Mbps or so.
    • Did some more exploring yesterday/last night and I think I spotted some LAA downtown but didn't get a chance to confirm before it went away in favor of mmW, which also went away pretty quickly. Also saw another n66 site, as well as an n2 site, making AT&T the second carrier to run n2 DSS within a few miles of me. I think at this point they won't be able to advertise anything flashy, but due to the sheer amount of CA they're throwing at customers here they can keep their network at 50+ Mbps until they can deploy both 3.45 and 3.7, and that's probably enough.
