And then you have to wait for good phones that can even USE that much bandwith (GS3 and GS4 limited to only 5mhz x 5mhz LTE).

 

I don't mind the wait, just saying.  :-)

An additional carrier would provide more capacity, IE if the G block 5x5 carrier is filled up, a 2nd A-F block carrier is available.  Similar to the current EVDO setup with multiple carriers from a tower to spread load.

Are the current G Block LTE carriers anywhere near capacity?  Nope, no need for additional carriers until the existing carrier is filled up.

Let's get NV finished so all the towers are upgraded, then see about this

There is a ton of Spectrum out there already, build more towers with smaller cells, share the existing spectrum better, reband the existing spectrum into useful wideband configurations rather than the crazy ass 30yr old narrow band configs.

WiMax in Columbus was very good the last few years when I've been there, but EVDO was terrible.  I always turned on WiMax when I actually needed good data, then turned it off to save battery on my OG EVO, then GS2.  Sometimes I couldn't get a simple twitter refresh on EVDO...

Columbus tower spacing always seemed to be fine to me, just need LTE and SMR and they will be golden.

There was a guy who used to post here that had family working in SoLinc, just about everything he said has come to fruition.  SoLinc isn't so much a public mobile company, but a two-way radio service for Southern Companies.  They don't care if it loses money, because the overall company rakes it in hand over fist and they need the radio service.

Sprint couldn't offer SoLinc enough money for its spectrum to get them to say yes...

This is a network still under construction, lets see what the signal strength was for those areas.  As Justin said, what is the signal strength compared to the other carriers.

I wonder how soon can Sprint begin to deploy the US Cellular spectrum in Chicago to add more capacity relief on their NV towers.

I thought Sprint was leasing the Spectrum back to USCC until they shutdown their network or the customer transition period completes, something like 12 months

As an example, T-Mobile launches markets for LTE when 70% of sites are upgraded (and they're upgraded at the same time that PCS HSPA+ radios are added). Their network is closest to Sprint's in that, nationwide, they have PCS-ish spacing and are doing a network overhaul on every site (in urban areas). But, again, the number is 70%, not 100%. And there's a distinct difference in coverage when every third site doesn't have a tech enabled.

 

Oh, and for refarmed PCS to launch in a market, the threshold was even lower, from what I understand.

 

On an unrelated side note, T-Mobile shares a few sites with Clearwire around here. Hence "PCS-ish" spacing rather than straight-up PCS spacing.

Also, T-Mobile already has enhanced backhaul (i.e. Fiber or AAV) for their HSPA+ AWS network, they don't need to wait for that to be installed.

Oh, come on. The FCC first established SMR about 30 years ago.  And for years after that, all mobile operations were narrowband, for which the SMR configuration is well suited.  You are playing Monday morning quarterback decades after the fact.

Yes I am, I can't see how it is logical to say "Let's design this "ABABABABABABABABABAB?!?"  How about we use logic and go "AAAAAAAAAA" then "BBBBBBBBBB" and the licensee can use that block how every they need it.

Clearwire is believed to be deploying TD-LTE in 20MHz TDD channels. Most likely with a 3:2 time slot ratio between Downlink and Uplink. A 20MHz TDD channel deployed in a 3:2 could almost reach 100Mbps in ideal peak situations and the proper backhaul.

Between that plan for Highspeed Data and a hopeful 20Mhz TDD in 600Mhz with PCS tower spacing for VoLTE, Sprint would be set for quite awhile, with a very strong network!

To bring some greater clarity to the SMR 900 MHz discussion, I have cooked up another of my famous graphs.

 

 

Note the interleaved nature of the SMR blocks; B/ILT blocks occupy the channels in between. At the very least, this is why Sprint cannot currently utilize its SMR 900 MHz holdings for CDMA1X or LTE.

 

AJ

What exactly does "B/ILT" stand for?  only thing I found via google was "B/ILT Business and Industrial Land Transportation."  Does this mean that some other form of communication is happening in those blocks between the iDen channel blocks?  Who designed this crap, a three year old?

Sprint just increased its offer to $3.40 per share.

 

Robert via Nexus 7 with Tapatalk HD

Wow, I saw maybe a small increase, but not $0.43/share, that is huge!!!

GRR!!!  So fricking annoying

 

AT&T might not be ideal, but Sprint isn't deploying 10x10 ANYWHERE for LTE.  the G-block is getting 5x5, and 800Mhz is getting 5x5.  It's only if they can get approval to buy Clearwire from the rest of the bitchy shareholders that they'll have a nice position in pretty high frequencies for something to the tune of 20Mhz worth of TDD-LTE.  

 

So while AT&T only has 10Mhz in some places, Sprint has it in zero, with plans for zero more.  Unless they get to buy Clearwire.  Tomorrow.

 

Seriously, what is the big deal with 10x10 or 10Mhz FDD, besides measuring your phones schlong in a speed test screenshot?  For 99% of smart phone users a 3-5mbs down and 1-3mbs up connection is more than enough for every possible mobile app out there.  Sprint has a great plan with 5Mhz FDD channels and when the Clearwire spectrum comes, they will have huge pipes in the BRS/EBS with TDD LTE.  But TDD won't even be 10x10, it will be a time divided ratio, I think Robert or AJ mentioned a 10:1 d:u guess.  5Mhz FDD G Block, 5Mhz FDD SMR, plus eventual refarming 5Mhz FDD in A-F Block will cover Sprint users very, very well with mobile broadband access.

While I agree that long term, the larger data pipes will be needed for mobile applications and services, that is probably 5 years down the road.  Sprint have LTE-A on their map and can look at Carrier Aggregation if they need high throughput in the PCS Spectrum at that time.  I really hope that Sprint gets their wish of TDD banding for 600Mhz and that works out to clear the 70-80Mhz that the FCC wants.  Then Sprint can hopefully get a 20Mhz swath and build out the future network for use around 2018.

I can not wait til 1x 800 arrives in my area either.  When at home I constantly bounce from roaming on a site that is less that 2 miles away and native sprint signal from a site that is roughly 5 miles away.  What confuses me is that I am usually between -105 and -115 from either of them.

 

I never have issues with voice calls at this signal but texting can be a pain at times.  The main problem is when Im roaming it causes my phone to burn through the battery while it just lays on the coffee table. 1x 800 will hopefully eliminate my roaming.

I would guess that you are directly pointing at the sector antenna for the further away tower, while the closer tower you might be right between sectors, causing the odd signal fluctuation.

This might be similar to the issues Chicago saw during the early NV roll outs.  The Samsung NV equipment was not "compatible" with the Legacy Motorola equipment, so changes towers was impossible and calls hard dropped.  I've actually seen it in Michigan too.  It you are on the border of an upgraded tower and a legacy tower, you might be bouncing back and forth causing some problems.

The North Lansing Tower off MLK/Grand River, near the railyard is broadcasting 4G

This sucks, Forum Runner is the way I view the site 90% of the time.

Hope a solution can be found soon...

When Sprint 800 Mhz CDMA is launched for us to use' date=' will the voice calls change from 800 to 1900 to 800 on the fly?[/quote']

 

Robert observed this when doing his field testing in Austin

Lots of towers in lansing and the surrounding area have antennas and rrus, guessing just waiting on backhaul

Just reproduced the handoff again on my way home. I started the call on Sprint, and it handed off to US Cellular!

I'd love to see engineering screenshots before, during, after handoff, and hangup

LOL trying to force my hand, are you?

Not at all When I was following I/O on twitter and saw that announcement, you were the first person I thought of with your App.

Gotta know your local SIDs, baby. And that, appropriately enough, is going to be the focus of my next engineering screen article. I am thinking of calling it "SID and NIDsy." Anybody get this music reference?

 

AJ

I'm guessing its a Sid Vicious/Sex Pistols reference?
