THis tower was being blocked yesterday at3:00 PM when I went through the area. I have not found a single active 4GLTE signal in North Houston recently.

Thank you it has been updated

I doubt that. PCS 1900 MHz licensees are not required to register individual sites. Yes, licensees (or tower owners) do have to register towers that exceed certain standards. But not all sites are located on towers, let alone towers that require registration.

Guess that would be why I had so much trouble finding many of the sites on the maps in the fcc database

8mbps in merrillville, indiana

Could you please take a screenshot of netmoniter while connected on LTE? This helps me find the tower so that a coverage map can be made.

I am trying to get my tuesday appointment changed to thursday so I can travel the wednesday instead of monday so I can attend this function. If we had an s4gru t-shirt I would have definitely worn it for sure.

Get the iron warmed up! And don't forget the other 1,000 members

In general, is there any way to translate the Network ID (NID) and Base Station ID (BID) values reported by netmonitor, which also seem to be the standard on-phone values detected by the Android utility Android System Info, to the site numbers reported in your maps? Is there a table somewhere that can cross-reference these?

Pretty sure that the BID is used in the FCC database for tower location, however the database is out of date, incomplete, and unsearchable to the point of being not useable.

There are a few towers within 2 miles or so that have been live since last month and the month before but I am almost positive those are getting blocked. There is one about 2 miles south west of your location thats schedule to have 4g turned on June 16th so you may be getting a signal from that one. When ever you leave where you are, if you don't mind, if you still have a 4g signal, could you please give an update as to your location? It would help me narrow down which tower it could from.

With that signal there is no way the tower is 2 miles away. more like 2 yards We might have a tower on a little early, closest I found using the lat and long is AT03XC001?

EDIT, Forgot he is in the 16th story, I am going to go with AT03XC089 or AT03XC088 as that is scheduled to turn on tomorrow

It has been brought to my attention that the coverage reported may be a little generous, I will post updated coverage maps tomorrow sorry for the inconvenience.

I just got a lte connection here in Houston.Im not sure the tower it came from but it was good while it lasted

If you are able to connect again could you take a screenshot of netmonitor so that I can find the site your connecting to?

Click on a Cascade ID for a coverage map of that site.

Update 6/15/2012, all maps have been updated to better reflect antenna configuration, this is still just an approximate guess as to coverage YMMV.

Interactive maps for sponsors can be found here

I will be maintaining coverage maps of LTE sites that people are able to or have been able to get a connection to. Please report in this thread if you are able to get an LTE connection along with the site location, Screenshots are helpful in verifying connection.

Even if you can no longer connect to the site please provide the information as the coverage maps will include those as well.

Hopefully this will allow for more efficient LTE site hunting.

Sites that I know of So far

I will get caught up on it this week.....

Atlanta

AT25XC056, Reported by danielholt, now blocked

AT25XC068, Reported by themuffinman, now blocked

AT03XC088, Reported by slackblade, allowing connections

Kansas City

KC03XC133, Reported by kckid, allowing connections

Houston

HO23XC275, Reported by techwrench, now blocked

HO33XC479, Reported by techwrench, now blocked

HO03XC425, Reported by techwrench, now blocked

HO03XC328, Reported by Latinoboi30, now blocked

Working on finding a way to display multiple .kmz files with image overlay on an online map. Any Ideas?

*DISCLAIMER, This is an approximation of coverage and no guarantee is provided that coverage will be there when you are so do not whine that its not correct, I only have tower height data for Atlanta at this point so all other towers will use an assumed height of 35 feet for urban sites. Antenna configuration including down tilt may have serious effects on actual coverage.

My evo is 30 minutes from my house.... Have my ups driver cell #, meeting him when first starts and getting off the truck. Will have early tomorrow. Sent from my PG86100 using Tapatalk 2

I miss my UPS driver, retired unfortunately for me.

No need to check by reference for me, Got email notification from Sprint that the phone was shipped!

There is a difference in capacity. Every base station will allow a certain amount of users depending on the amount of spectrum allocated. The 700 mhz spectrum has a much larger coverage area per base station than higher frequencies. This can be mitigated with downtilt, but the higher frequencies allow higher capacity by default.

I was referring to what I perceived was a statement that higher frequencies supported higher bandwidth in that they could carry more bits per hertz than lower spectrum. Even considering the propagation differences the capacity per channel in terms of users is still the same irregardless of cell size each cell would be able to support the same amount of users per cell how does this effect capacity?

*edit* Other than the overall network capacity. Which no doubt with little effort and expense can be effected by tower height, downtilt, and power output.

I do not know how much you know about spectrum but there are advanatages and disadvanages to the different types of spectrum.

 

The 700 A band is plagued with interference from TV. The 700 A B and C bands are not truly one band but multiple bands that can not easily be used in the same phone. All 700, A B and C, though are great at having the signals travel but not that good a capacity

 

The AWS is one of those ands that is the best to build on because it consist of 1700/2100 bands that give capacity and also travel good deals. Personally this is the best spectrum

 

The PCS is on the 1900 band and is again a good band for wireless connections like the AWS spectrum

 

2.5/2.6 spectrum is personally better then any spectrum listed above besides AWS or PCS for cities like New York because it gives high capacity. A high capacity network old be able to support the large population. You may have to locate the towers close to each other, with in a 1 mile range I believe for a constant network.

 

The only band I did not mention above is the 800 band but I have little knowledge

The various bands do not have any capacity advantages over another considering the same amount of allocated spectrum. The advantage of the higher frequencies in a phone are the smaller antennas required allow for more to fit into a phone handling more bands.

A hostile takeover of Clearwire would be impossible without also taking over Sprint, so I doubt DT wanting to get out of the U.S. market will end up expanding Tmobile and no way the FCC allows VZ or ATT to take them over. Regarding buildout costs, in urban areas it should cost no more than any other additional spectrum that Sprint would acquire with NV. In fact NV was originally planed to host clearwire spectrum.

No sites in the Atlanta market have 3G NV upgrades live yet. None. Zero. Zilch. Only LTE enhancements live so far in Atlanta/Athens area.

 

On another note, 1xAdvanced can be deployed for capacity/signal strength gains or speed gains, not both. So if Sprint deploys 1xAdvanced for maximum capacity, speeds stay right around 144kbps maximum.

I'm guessing maximum capacity, being able to effectivly get 8 channels out of 2 means more LTE in the PCS Band. If I was Sprint I would demand all non dumb phones have LTE capability by next year like Verizon. Dumbphones could be required to support the 800 band 1x advanced than. By 2014 they should only need 1 1xadvanced channel on pcs, saving all the spectrum for LTE, perhaps leaving 1 evdo channel

The part where it gets interesting is - how do you guarantee a consistent user experience?

 

You are on someones unknown femtocell and their broadband connection drops out and your call drops. Sprint is taking on that liability.

 

I suppose if you are going from zero coverage to some sort of coverage - that's an improvement... but if you are trying to use femtocell as some sort of pico cell to offload traffic... it could create an inconsistent user experience.

 

I wonder if the next gen femtocell will have self-diagonstics - testing speeds/latency/jitter. If it fails, the femtocell will blink red and not operate.

I have never had a dropped call on my airvanna and my internet connection goes out all the time, I get about a 1 second cutoff and it switches to the regular network.

Actually come to think of it I have never had a call drop on sprint unless I was driving somewhere in WV no cellphone land, My wife's IPhone however drops all the time usually with good displayed signal as well.

looks like someone needs to activate windows

Guess the releasing 800smr support to all capable customers is a non-event eh?

Might be a little more excited if I had my Evo LTE in hand and it was November. Till then it does me no good.

I should have been more clear, sorry clearwire *is able to* As I said in my second post 2 or 3 is more likely. The 100mhz was a clearwire marketing guy trumping up what they could do with there network in response to a question about competing with the big 2.

 

 

Also what polarity do the towers use? Vertical or Horizontal?

Vertical

50x50 = 1gbps download speeds on LTE!!!

yep but its td so its a big 100mhz slice not 50x50 clearwire says they can then allocate capacity to the up and down link as needed. Now just because clear can have a 100mhz slice dosen't mean they will do it. Most of what I have read from Clearwire interviews was 2 or 3 20mhz channels bonded. Apparently bonding much more than that has a drag on efficiency. The point is however that spectrum is the least of Sprints concerns. More pressing is getting the money to pay for all of this.

now for the bad news... an LTE tower thats on the LTE Active list for Athens:

AT04XC508

 

is not allowing LTE connections, further... the 3G speeds are under half a mb per second, with me sitting right in front of the tower...

 

3g is not active in the athens/atlanta market so that would be expected I believe, I was going to map out coverage of that tower for everyone tomorrow and those LTE speeds are downright sexy.

For those worried about capacity issues with sprint Clearwire has said they can aggregate a 100mhz channel with LTE advance next year with only a software upgrade required after a tower has the LTE equipment and they have an average of 160 mhz of spectrum nationwide, about what att and Verizon have combined.

20mb down... 9 1/2 mob upload ... Athens.

Could you tell me which tower you connected to? On the tower map it will have a cascade ID that starts with AT. If I know which tower I can map out the signal

I lived in an official market as well the last 2 years (Cleveland) and didn't know what everyone was complaining about. We ended up using it for office internet as well DSL was maxed out at 1.5mbs and TWC wanted 8 grand and a 2 year contract at 200 a month for cable internet. We got 15-20 down 2 up for 35 bucks a month no contract from clear to go along with the evo 4g for everyone in the office.

There was a issue about CDMA activations a few years ago. Verizon claimed that untested devices could cause interference issues with there network, however they agreed to test any manufactures phone they otherwise wouldn't carry and approve it for its network, after that I have not heard of a single phone that had gone through the process. Because the Nexus is already approved on both Sprint and Verizon's network If google wanted to sell them I don't think that the carriers would raise to much of an issue with it.

apparently sprint is part of the open handset alliance, sounds good but a review of there discussion boards has employees saying if you want to use another phone you have to figure out how to activate it yourself as they will not help or support anything. Duffman is a sprint employee right? he could have some insight
