Sprint TD-LTE 2500/2600mhz Discussion


Recommended Posts

Does anyone know how many sites Clear has by itself?

 

Seems to me that by acquiring Clearwire, they are getting themselves into a bit of a Nextel situation, taking on additional sites that they don't really need, increasing their costs.

 

I'm assuming that any 2.5 LTE (and possibly WiMax for backwards compatibility) will be deployed on existing Sprint sites to reduce expenses from multiple leases etc... coupled with the fact that most Clear sites are situated MUCH lower on the tower than the Sprint sites, it seems like would only make sense... Use only the Clear sites that are sitting in Sprint dead zones, and upgrade the other sites directly onto Sprint sites (I seem to remember seeing a slide about this when NV was first proposed, but it never happened--they changed the story to doing it with LightSquared, then never seemed to mention it again... I believe a few of the LightSquared sites were even completed)... of course they didn't do this with Nextel, so we'll see if they do it this time... the only difference being is that it will be a lot easier this time since all the new NV gear can take on LTE at 2.5, and even WiMax with the software defined radios...

 

If memory serves, 14,000 sites in the CLWR network.

 

However, 40% of Clearwire sites are colocated with Sprint CDMA sites. These can be moved over to NV cabinets and racks pretty easily and save money without any change in coverage. And how many of the other 60% are redundant coverage from nearby Sprint sites?

 

The New Sprint will be very coganizant of these points and will reduce Clearwire cost significantly. I'm not worried about this at all. This will be nothing like Nextel.

Will they have to deal with the same permitting hassles they're dealing with replacing the cabinets and everything else at every site, or since they're just moving existing equipment would that mean they don't need permits for that?

 

That's just one point I see continually brought up as something that delays progress currently.

 

and god help us if there are birds.  DAMN YOU BIRDS!!!   :P

At existing Clearwire sites, there will be very little permitting required except in the most red-tapish kind of places.  However, at Network Vision sites, adding TD-LTE to the mix will require an additional panel.  So that will probably be a threshold where permitting and plan review will be triggered in 60%+ of jurisdictions.  I think it will be a quick review in many places though.

Would sprint install panels that are 2500mhz only or would they go with Some type of dual mode/dual band antennas that would be compatible with future bands that they are likely to acquire? To save space on the towers like they have done with the nv panels.

Which extra band do you suggest? Kind of premature to know the next band used. Since there are so many different LTE carriers possible in the EBS/BRS bands, there may not be enough room inside the panel for more antennas than just these bands.

Maybe a panel for h-block/2500mhz being that Sprint most likely will be the only bidder. But then what if they don't or can't bid on it they will be screwed. Never mind

It's likely the existing NV panels/antennas can be used for H block. However, the existing 1900 RRU's cannot, though. It's possible that the existing 1900 RRU's may be able to handle H block with a firmware update. If not, then an additional H block RRU may be needed.

 

Sprint is not in the position to invest in hardware for other bands beyond PCS, SMR and EBS/BRS at this time.

Lets just hope that Sprint can salvage something from the existing NV panels/antennas or RRUs for the H block.  It sucks that Sprint would have do all this for a 10 MHz block of spectrum but Sprint has shown great interest in the H block so they must have known going in that they would have to deal with this issue eventually.  I hope a firmware update is able to resolve this issue for the H block in the existing 1900 RRUs.  Hopefully Sprint can talk to the OEMs about how to deal with the H block situation with the existing 1900 RRUs.

Any news on the New Sprint launching TDD? Possible announcement during 2nd quarter meeting? Will Sprint phase out Clearwire brand? Would be nice to get New Sprint internet hotspot unlimited on TDD.

So far no new news but I'm sure we will get some good news soon. To my knowledge clearwire already had 2,000 sites ready to be linked to the sprint network, we have a couple Triband hotspots releasing sometime this summer and LG and Samsung are expected to release a Triband phone later this year

 

Other than that I really don't know lol. We just have to wait and see

they won't phase out the clearwire brand, they're going to outright kill it.

 

And don't hold your breath for an unlimited hotspot

One site just down the road from me has Sprint on a billboard sign in front of the local Save A Lot grocery store. Clear wire and a bunch of others are on a large tower behind the store. Seems like they should be able to same some money and move one or the other 100 yards.

You would think they would have planned for this when buying G block compatible antennas and RRUs, they had to know this was coming. Something like swapping out the 1900 RRU or just updating the firmware?

i would think so as well but the argument about having the appropriate filters and such to support the H block power restrictions comes into question as to whether the current 1900 RRUs are able to support it.  Its really the 5 MHz of downlink frequency that is not currently supported by the 1900 RRUs.

 

The problem with swapping out the current 1900 RRU is that you spent all this capex on these expensive 1900 RRUs only to take it down a 2-3 years later or in some cases just 1-2 year if you are a 4th round market and not to mention the permitting and manpower required to install these new RRUs is time consuming.  I just hope that the 1900 RRU can be FCC recertified via a firmware update...*crossing my fingers*.

Eric, I started my WiMAX center frequency vs carrier bandwidth data dump into a spreadsheet.  Egads, man!  There in Southern California, you are like a WiMAX porn star.  You have been with way too many different sites.  You are damaged goods now.

 

:P

Found anything interesting for the Wimax center frequency vs. carrier bandwidth in your chart?  i would be curious to see at which frequency range could Clearwire could be using to launch TD-LTE.

No, we probably will not be able to see if Clearwire has been doing any specific spectrum refarming for TD-LTE.  The WiMAX center frequency data extracted from your Motorola Photon is not time/date stamped.  So, we cannot tell when you connected to each particular WiMAX carrier.  It could have been yesterday or last year.

 

That said, I will finish my work and make available a download later today that I think you will find quite interesting...

When I use the ##33284# (##DEBUG#) dialer code, there is a Wimax engineering menu that you can monitor which frequency you are connected to.  You set it to monitoring status and I have noticed that between towers I do switch frequencies.

Yes, Clearwire is using a frequency reuse pattern for its WiMAX network.  Each site/sector should be on a different WiMAX carrier center frequency.  So, my point is that some of those WiMAX carriers you may have connected to recently.  Others may have been a long time ago.  As such, we do not know exactly what spectrum Clearwire currently has allotted to WiMAX and what has been potentially cleared for TD-LTE.

 

Regardless, here is the fruit of my labor.  It was an arduous yet enlightening task, and I thank you for the data, Eric.

I found a link i found interesting. I wanted to see what kind of performance Softbank's TD-LTE was getting in Japan. According to the link, Softbank is using 2.6ghz spectrum in a 30mhz channel. Pretty good performance i would say.

 

http://www.huawei.com/ilink/en/success-story/HW_195558#.UeQvY9hnaqk

 

For those that do not want to read:

 

Spectrum: 2.6ghz

Channel width: 30mhz

DL Speeds: up to 76Mbps

UL Speeds: up to 10Mbps

Though Clearwire has said that they plan on upgrading until they reach peak speeds of 168Mbps in 2014.

    • Here's the spectrum breakdown by band. There's some 2.5 in there as well. The remaining spectrum is definitely enough to keep running FWA on while finding a buyer, and since the towers aren't conveying with the subs and spectrum there's nothing stopping USCellular from competing with T-Mobile on FWA until Verizon or AT&T decide the spectrum is valuable enough to take off TDS's hands. If they go that route, I wouldn't be surprised if FWA gets rebranded under TDS.
    • Transaction Details and Financial Profile T-Mobile will pay approximately $4.4 billion for the assets being acquired from UScellular in the transaction in a combination of cash and up to $2.0 billion of debt to be assumed by T-Mobile through an exchange offer to be made to certain UScellular debtholders prior to closing. To the extent any debtholders do not participate in the exchange, their bonds will continue as obligations of UScellular and the cash portion of the purchase price will be correspondingly increased. Following the closing of the transaction, UScellular will retain ownership of its other spectrum as well as its towers, with T-Mobile entering into a long-term arrangement to lease space on at least 2,100 additional towers being retained. T-Mobile does not expect the transaction to impact the company’s 2024 guidance or 2024 authorized shareholder return program. T-Mobile expects this transaction will yield approximately $1.0 billion in effective total opex and capex annual run rate cost synergies upon integration, with total cost to achieve the integration currently estimated at between $2.2 billion to $2.6 billion. The company plans to reinvest a portion of synergies toward enhancing consumer choice, quality and competition in the wireless industry. The transaction, which is subject to the satisfaction of customary closing conditions and receipt of certain regulatory approvals, is expected to close in mid-2025.
    • The way I heard it, these were for sites that T-Mobile would not be keeping, and presumably is how they would handle decommissioning the equipment from them.  This would presumably happen because they're already on the tower or on an adjacent tower.  For example, in Keysville, VA, T-Mobile is on a tower directly adjacent to the existing US Cellular-owned tower. https://maps.app.goo.gl/kefNy451QXYFSqi5A T-Mobile at left; at right is the US Cellular-owned tower with both US Cellular and Verizon gear on it. - Trip
    • My gut opinion is they are waiting for technology improvements. C-band is seeing some of those emerge now which will extend its useful range and carrying capacity.  Given it current short range, 24GHz is best for places where people are seated in sizeable numbers, although I would not rule out business pico cells. Of course, Verizon is using mmWave small cells quite well for FWA by placing them outside large apartment buildings that only allow one ISP with outrageous charges. UScellular and some Verizon have been using it to do the job of microwave links to preserve licences (4 needed per county).
    • Looks like T-Mobile is consolidating around 24GHz for mmWave. Curious to know what their plans are for that.
