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

Recommended Posts

Huawei DBS 3900 TD-LTE / Wimax eRAN Equipment

 

The following photographs are pictures of Huawei dual mode capable Wimax / TD-LTE RRU (remote radio units) as part of a DBS 3900 series setup. These equipment were originally made for the Clearwire Wimax deployment and are now being re-purposed via software upgrades to enable TD-LTE capabilities. 

 

The Huawei equipment currently used by Clearwire are temporary and will be replaced by one of the TD-LTE vendors (Samsung / Alcatel-lucent / Nokia Solutions & Networks ) in the near future.

 

As of 2017, all Huawei equipment has been decommissioned.

Is it just my connection, or is the topic written in another language?

Now its showing up in Chinese. I swear the first time read the topic is just listed a bunch of random meat types.

 

I'm still laughing......

Wait so Huawei has dual mode WiMAX/TD-LTE too? Have other vendors (besides Samsung) started making dual mode WiMAX/TD-LTE equipment too?

I was under the impression that it was all going to be dual mode since they don't plan to decommission WiMAX for another couple of years.

I think this is what we have here in Columbus. I haven't seen Samsung equipment like I thought I would since we're a Samsung NV market.

I would guess Clearwire had already ordered (and probably installed most of) these prior to the merger going through. The fact that it is just a software update to use it as dual mode would suggest they will leave it in place as long as they can. The new dual mode Samsung equipment is probably heading first to older clear sites that can't be upgraded by software.

Are we sure that Sprint has signed agreements for the network wide deployment of 2500/2600 TD-LTE? It is conceivable that the vendors might win contracts for different areas for NV 2.0 than NV 1.0....

My original thought was that since Columbus Sprint NV is Samsung that Clearwire may have went the same route initially.

Doesn't the Huawei equipment need to be torn out and replaced in order to comply with the conditions of the Softbank purchase of Sprint? How soon does that need to happen?

That would certainly make it easier for everyone if that is the case. I guess we will see a pattern as they roll out the equipment,

This one yes. 

Would either of the two smaller panels be for wimax? The one just to the right of the far left NV equipment is gone now

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.

They are upgrading the microwave in many instances.  It's a case by case basis depending on capability/demand.

Oh I see. Are microwaves just has good as fiber? Why would Sprint not use microwaves on Sprint towers?

Who in the heck is the vendor that installed this weird looking wimax equipment?

I thought we had huawei equipment but I've never seen one like this.

I'm guessing the bottom rack? Maybe? ...

      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.

      hey guys i m curious what you guys think about rooting phones and the positives and negatives about it.... let the discussion begin!

      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!
