How to Spot Clearwire TDD-LTE / Wimax Antennas & RRUs (Huawei)

Recommended Posts

What are we suppose to look at?

bottom rack, the other two are Verizon, AT&T. The bottom ones are what look like to be the wimax equipment, with the RRUs behind the round panels

I don't see any panels or RRUs. 

 

I do see some antennas that do not belong to Clearwire. 

 

OIC. Clearwire protection site. Not clear enough of a picture to determine whose equipment it is. Probably motorola or Samsung.

What are those bottom level panels ? The RRU is attached to the back of the farthest right round panel. Kind of hard to see, didn't help it was dark. But it is the only level that resembles wimax. It is on a wimax protection site

It almost looks like an omnidirectional, did Clear use those?

Those are sector antennas.

90% of the Protection Sites I've seen are Huawei gear. The ones in Lamesa Texas, Flagstaff Arizona and North Bend Oregon are the ones I recall off the top of my head that were different. At least of the ones I've seen. I have seen a couple others too. The other 50 or so Protection Sites I've seen are Huawei. All the ones in NM are Huawei.

Hey I was wondering why Sprint will keep using microwave backhaul on clear sites and go to fiber on Sprint sites? I'm assuming it's a cost thing and why Fix something that isn't broke right? I'm assuming the microwave way is still very efficient back haul?. Thanks.

It can be. It works fine as long as the link has sufficient capacity. You can easily do 1Gbps full duplex at the distances required for 2500MHz site spacing.

 

The issue comes in with how many hops are required between points where the network is loaded. Ex. 3 sectors TD-LTE will require about 450 Mbps in a perfect world, about 250 in a more real world. This means that with a 1.5 Gbps connection, four or five microwave hops would be a practical maximum.

I need to get you some Michigan pictures. Some are pretty odd.

Those look kinda like the stupid "stealth" sheath things that are on some towers in Charlotte. I don't know why they are used (consistency among carrier racks, I guess?), and I think they just slow down site upgrades. If you can get closer to the site, does it look like those are just cylinders that are open at the tops and bottoms with antennas inside?

yes and you can kind of see the rru attached to the cylinders, i cant get closer to the other two protection sites In town, but this one I was literally Right underneath it.

 

Looks just like this

Ahh. I thought so. I guess you have to go off of the RRU for identification. Which is better than seeing the antenna in most cases anyway. It would be best if you could get a photo with a camera with a zoom lens just to be sure, but I don't know of any other carrier using antennas of that height with RRUs of that size. So it's probably safe to assume it's Clearwire. :)

Oh i know it has to be clearwire gear. But finding the vendor is what im curious about, im going to try and borrow one to focus on the RRUs and possibly another sight or two. Thanks for the thought that it might be a stealth container. Never thought of it

Here are some better shots I got:

And here is the closest I could get from another Protection site, without the stealth containers:

Second one is Samsung. First one is unknown.

 

Sent from my Nexus 5

I figured it was Huawei or Samsung. The first set, those couldn't be Expedience equipment could they?

Is this picture any better, I cant really tell, but it looks like maybe a small RRU inside of some sort of casing

The only really distinguishing feature I can really see is the what appears to be a microwave antenna of some kind that the Samsung equipment seems to lack. The antennas themselves look to be roughly the same size. I see a lot of these when I'm in Sprint's WiMAX footprint in Cleveland, OH.

 

While I'm thinking about it, is there a glossary of terms and acronyms somewhere on S4GRU? It took me about a month to figure out that a "RRU" was a remote radio head, and I still have no idea what a GMO is.

Guys, can someone help tell me which one of these racks is WiMax? These are my local towers, and curiosity got me today, and I took a block long drive down a private drive to take pictures. This thread feels dormant, but hopefully sees this.

I think the second rack from the top is an example of Clear protection site equipment (it's the only one with one antenna per sector); it looks like the other Huawei pictures in this thread, but I can't tell definitively. No evidence of TD-LTE live here. (This is the Clear protection site on Russell Parkway in Warner Robins, Georgia.)

Is there a number available how many Huawei radios / sites are still on air? What is the replacement priority for Sprint to comply with the .gov?

      The 850 MHz LTE Sprint network is so congested in De Soto MO. I also have proof on my SDR Radio.
       My SDR Radio can only show 1.920 MHz of the 5 MHz wide LTE Signal.

      I notice a lot of post regarding the markets in IL,FL,TX,PA,NYC.... but how about about the Los Angeles market? I THINK it was samsung doing the set up for the L.A market? Not sure though.... I'm not a sponsor member of the site so I can't really check... if I had a job I'd most definitely donate!
       
      Couple of months ago the local towers were all down and being upgraded to NV I assume since Larry from Howard forums said there was NV work being done my zip code. The speeds were better for a bit but now they are awful again.
       
      Can anyone (most preferred Robert) make a comment on if there is any LTE activity near 90255 area code?
       
      Thanks, great site by the way... I'm a Lurker.

      Did you know that with many Sprint (Uniband) LTE Android devices, the signal strength indicator at the top does not show your LTE signal strength? Even if 4G or LTE is displayed next to it?
       
      That's right!  This signal displayed here is your 1x (voice signal), and it is not your 3G EVDO signal strength, nor your LTE signal strength.  Regardless of whether it says 3G or 4G next to it. This is the cause of a lot of confusion.  Also, third party apps like NetMonitor do not show accurate LTE signal strengths. They also only show the 1x signal strength, even though they may reference being connected to LTE.
      The purpose of this thread is to help educate the masses, because many people think they have a strong LTE signal, when in fact they do not. And then they are unhappy, thinking that Sprint LTE is really slow, even with a strong signal. LTE performance is very signal strength dependent. So, when you have a weak signal, you can expect much slower than peak results.
       
      There is only one accurate way to get your LTE signal strength, and that is from your LTE Engineering screen in your Debug menu. And we will discuss the different ways to get that below.
       
      ...In HTC, Motorola & LG Sprint LTE devices:
      Go in to your phone app, and dial ##DEBUG# Select LTE Engineering Go down to RSRP. The number under RSRP shown in dBm is your LTE signal strength. ...In Samsung Sprint LTE devices:
      Go in to your phone app, and dial ##DEBUG# Enter 777468 for your lock code Select LTE Engineering Go down to RSRP. The number next to RSRP shown in dBm is your LTE signal strength. ...In the Galaxy Nexus, Nexus 5:
      Go in to your phone app, and dial *#*#DEBUG#*#* Enter 777468 for your lock code Select LTE Engineering Go down to RSRP. The number next to RSRP shown in dBm is your LTE signal strength. The LTE Signal Strength Scale:
       
      Now you have determined your actual LTE signal strength in dBms your device is receiving, you can use the following scale below to determine its strength:
      Better than -88dBm RSRP is a strong signal Between -89dBm and -96dBm is a very good signal Between -97dBm and -105dBm is good Between -106dBm and -112dBm is fair Worse than -113dBm RSRP is poor Feel free to link people to this thread for explanation. Hopefully, this will clear up some confusion out there!
