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

Recommended Posts

RAvirani    759

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.

Yea I have seen those microwave antenna thingys on huwei equipment too...does anyone have any idea what those actually are?

Backhaul. A great many Clear sites use Microwave for backhaul.

Oh.  Is Sprint getting better backhaul for the sites converted to B41?

Microwave is perfectly acceptable backhaul in most cases.

True but not how Clearwire deployed it.

Clearwire set up its microwave backhaul network with the anticipation they would need only 5-15Mbps per sector/channel. The equipment/links themselves each could support a lot more throughput than they did. The big limiter in the Clearwire microwave deployment was the amount of backhaul being supplied at the source point and the number of hops to the terminal end of the chain.

 

By the time you got to the end of a Clearwire daisy chain, you could be 8 hops to the source. That really reduces performance. Especially if they all are sharing one 100-200Mbps connection at the source end. Which blows my mind, as I have 200Mbps at my house now.

I didn't think Huawei was a Network Vision partner, or are there markets where there isn't a Network Vision upgrade, but using older Huawei equipment, which since not upgraded as part of NV, won't have CA?

It's not. This is Clearwire equipment we're talking about that was deployed in first wave of WiMax.

Ah, OK. Does this apply nationwide, or only in certain markets? I'm curious if this is the case on Clear towers in the Chicago Market, or since the Chicago Market has Samsung as the vendor, are the Clear sites using them here or Huawei?

No, only certain markets. And the WiMax vendor markets do not match up with the Sprint NV vendor markets. Chicago has Samsung dual-mode RRUs, which is why you have already seen the 2nd carrier deployed there on Clear sites.

Network vision vendors will come and replace these. Right?

So as of now, CA cannot be deployed in non upgraded areas?

For those sites that still have all Huawei equipment. Any Sprint sites are good to go. Any sites with the second release of Samsung's RRUs are good to go.

That's pretty much the whole Seattle area. Samsung hasn't done much on the 2.5 side here

All the Sprint sites with B41 are on Samsung equipment. Hundreds of them in the West Washington market.

They're in the premier sub-forum. The thread is even pinned... it's not that hard to find. TD-LTE sites accepted.

      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.

      hey guys i am due for a upgrade today....i am curious on the opinions of others of what phone is a great phone... any opinions are welcome !

      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!
