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

Recommended Posts

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?

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.

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

I've seen them but in most of the areas I'm in, there's still huwei equipment

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

    • Excuse my rookie comments here, but after enabling *#73#, it seems that the rainbow sim V2? requires n70 (I turned it off along with n71 - was hoping to track n66) to be available else it switches to T-Mobile.  So this confirms my suspicion that you need to be close to a site to get on Dish.  Have no idea why they don't just use plmn. To test, I put it into a s21 ultra, rebooted twice, came up on T-Mobile (no n70 on s21).  Tried to manually register on 313340, but it did not connect (tried twice). I am on factory unlocked firmware but used a s22 hack to get *#73# working.  Tried what you were suggesting with a T-Mobile sim partially installed, but that was very unstable with Dish ( I think they had figured that one out).  [edit: and now I see Boost sent me a successful device swap notice which says I can now begin to use my new device.  Sigh.  Will try again later and wait for this message - too impatient.]
    • Hopefully this indicates T-Mobile hasn't completely abandoned mmwave and/or small cells? But then again this is the loop, so take that as you will. Hopefully now that most macro activity is done (besides rural colo/builds), they will start working on small cells.

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, FWA Mobile in RVs in Walmart parking lots working where mobile phones need all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71, 90% 5g.  93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77 also with its shorter range.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
