[EVO 4G General] alvintimothyjr:
I live in the South Park area in San Diego. I am getting intermittent 4g access on my evo. I would think 4g is on the way for SD...finally!!
[EVO 4G General] jefbal99:
I think clear has two towers up in the San Diego area.

Check out http://www.clear.com/coverage and zoom in on SD
[EVO 4G General] mayate:
after reading this i tried connecting to 4g... the clear coverage map didnt show coverage in my area but i was able to connect... granted it was poor signal but my speed down was 1.9MB and up was still crap .95KB :D
[EVO 4G General] flipper12:
To mayate, out of curiosity, where abouts in the SD area are you located?
[EVO 4G General] blackroseMD1:
Man, I hope so. I live right downtown though, so don't know how great of coverage I would get with all these huge buildings around. From the looks of the Clear map, I need to move over by San Diego State...:p

Edit: Turned on WiMax and let it scan for a couple minutes, but got nothing. Hopefully they fully kick it in soon.
[EVO 4G General] jrdejavux:
i noticed late last night i didnt have any 3g in chula vista. maybe there are setting them up?
[EVO 4G General] atypical1:
I work in the Mission Valley area and I'm not getting anything. I live in Mission Hills and I'll try it there too but I would be really surprised if I got anything.

I bet that SD would be a tough area to cover simply because of all the hills but who knows.
[EVO 4G General] blackroseMD1:
If you look at the clear map...Mission Valley has a tiny bit of coverage, but not much. The SDSU area is absolutely saturated, and getting over towards La Mesa has quite a bit of coverage too. Hopefully they expand the rollout, although I doubt downtown will ever have great 4G coverage.
[EVO 4G General] mayate:
i live in the national city area... about 3-5min away from chula vista... i can finally post attachments so ill show my results
[EVO 4G General] jrdejavux:
what part of national city???
[EVO 4G General] mayate:
if you check out sensorly around euclid and 16th theres a dab of green randomly =P

the only detail i can actually give after that is the exact address... no thanks =P

if my lazy ass ever decides to go for a walk ill see how much i can expand that green

EDIT: After some driving around I found full bars around the highland Walmart/99¢ store
[EVO 4G General] Shigster:
sweet I live by IB, and I haven't gotten anything down there but hopefully soon!!
[EVO 4G General] ruben1221:
I live in spring valley and I will give this a shot. I work in la jolla at ucsd so I will give it a shot there too. I ll give feedback when I get a chance.

Sent from my HTC EVO phone, shouldn't we all have one? :)
[EVO 4G General] cornelious1212:
No dice at USD.

Sent from my keyboard, using my thumbs.
[EVO 4G General] dwntwnall4u:
No luck in Kearny Mesa area.
[EVO 4G General] shoobshoober:
sweet clear map shows coverage at ucsd. gonna try it during school tomorrow
[EVO 4G General] lehalter:
I will be in San Diego tomorrow...hope I can finally use 3g!
[EVO 4G General] Shigster:
LOL I go to school at UCSD and I couldn't get a signal at Revelle or at Sixth...how did it go for you?
[EVO 4G General] alvintimothyjr:
I'm in Southpark and have been connected to the 4g for about 15min 7pm PST...

cm7Evo
[EVO 4G General] jrdejavux:
what are in southpark? i am headed that way in a few and would like to try it
[EVO 4G General] alvintimothyjr:
I'm close to the south park Abby whistle stop area...the signal goes in and out and its slower than 3g....I think its just testing going on. This signal is reported "strong" in my settings however.

cm7Evo
[EVO 4G General] skennedy843:
I have 4g in San Marcos. I get 2500 inside and 6k outside. I hope I get signal at my work. Its about damn time we start to get 4g.
[EVO 4G General] ruben1221:
I got nothing around UCSD

And nothing in spring valley. But I did get good signal in Montezuma area next to SDSU. I got pics :-)
[EVO 4G General] alvintimothyjr:
South park San Diego

cm7Evo
[EVO 4G General] alvintimothyjr:
Its still slow with a inconsistent signal...

cm7Evo
[EVO 4G General] alvintimothyjr:
I'm in south east Diego....very strong 4g signal.

cm7Evo
[EVO 4G General] jrdejavux:
WTF? i been all over town today and no connections to 4g at all! WTF ugh
[EVO 4G General] alvintimothyjr:
Seriously...I can only get it in the south east region..I'm in Southpark and the signal is not stable. However I was in the "hood" earlier today and got a constant strong signal. When I say south east...I'm mean Logan.

cm7Evo
[EVO 4G General] atypical1:
4G comes at a high price...lol
[EVO 4G General] rensouken:
I'm near the J street Marina next to I-5 in Chula Vista...I get nothing :(
[EVO 4G General] jefbal99:
My buddy lives on Costa Verde Blvd off La Jolla Village Dr and gets solid 4g
[EVO 4G General] slipshft:
To put an end to the speculation... The sites in SD are for spectrum holding and are not full bandwidth sites. So the connections will be limited and slow. Some of the sites will have better through put than others, but there are only 5 sites in SD that are transmitting. Sorry, but I cannot disclose where they are.
[EVO 4G General] shoobshoober:
I think at ucsd I picked up a weak signal around peterson and muir. But i was in between class so I wasn't sure if the 4g was actually 4g and not wifi.. it's kinda weird on cm7 sometimes. Will give it another shot today.

either way low signals for now
[EVO 4G General] ruben1221:
Im near UCSD right now off of La Jolla Shores Drive. I get on/off 4G but with poor connection.
[EVO 4G General] blackroseMD1:
Well, seeing as how Sprint has told me, since I bought my phone in June, that we would have 4G at the end of Sept/Oct/Nov/Dec and now the end of the 1st quarter (which has passed), Clear and Sprint need to get off their asses and upgrade those sites to full bandwidth and make good on the things they actually say.

I know Clear is hurting for cash right now, but if the sites are already there...turn them on full blast!
[EVO 4G General] sal87:
Im in escondido i picked up 4g i was at the san marcos street fair yestarday and the signal seemed alot stronger
[EVO 4G General] djhspawn:
Anything else you can inform us?
[EVO 4G General] lehalter:
I was in San Diego this weekend and I could not find 4g anywhere. I'm disappointed.

On the bright side, I have been using CM7 recently and I am really beginning to enjoy how much you can change about it.
[EVO 4G General] slipshft:
I would love nothing more...
[EVO 4G General] alvintimothyjr:
That explains a lot. Thanks.

cm7Evo
[EVO 4G General] alvintimothyjr:
I heard that man...turn those MF's on already

cm7Evo
[EVO 4G General] culua:
I'm amazed how fast 4g with 1 bar of signal. I wonder how fast it be with full bars.
[EVO 4G General] blackroseMD1:
I got my first connection at 38th and El Cajon Blvd the other day. I was using an older CM nightly, though, so when I went to run a speed test, Wimax started disconnecting and scanning over and over.

Gonna be up by SDSU today, so I'll check out the connection there.

Edit: Funny thing is, if you go to Sprint's coverage map (not Clear's), it says that San Diego has 4G, and SD is also in the city list. Maybe it is coming soon after all.

[Off-topic] SciFiSurfer:
My work just got in a Nintendo 3DS, and it's really cool to be able to get 3D depth perception on a flat panel display without glasses.

Of course, they have the whole 30 minute viewing warning thing going on, so...
[Epic 4G General] Txdaredvl:
4g wimax/ LTE both? :eek:

Got the epic a few weeks ago and the display sheet for the phone showed wimax and lte but the evo didn't. So I asked the sale person if it is a typo and he said no. The phone would need just the software to enable the LTE. He asked a co worker and he said the same. Does the epic actually have a wimax/lte enabled chip or are they just going by a typo? Was just wondering as I know sprint is looking at LTE now.
[Epic 4G General] Kcarpenter:
Highly doubt it...there isn't much of a way to get a sim card in the phone...
[Epic 4G General] LordLugard:
A combination flustercuck of a typo and reps who don't know what they were talking about.

Epic has no LTE hardware.
[Epic 4G General] Txdaredvl:
I figured they were stupid. I figured if they really put both chips in here the cost would be more kinda like a global phone. Would be cool though if they would and allowed us to use verizons lte just like roaming on the 3g side.
[Epic 4G General] jbadboy2007:
Lte doesn't need sim cards and he didn't say gsm say your response is not valid. I'm not 100% on this but all sprint has to do for lte is switch out very minor things. The only difference with our phones is the spectrum it is looking for. So since we have 4g and maybe the software can make it lte. Its possible I think.
[Epic 4G General] ichefae85:
Doesn't LTE require a sim card though? I remember seeing a sim card on the thunderbolt
[Epic 4G General] rocket321:
http://www.google.com/m/url?client=...YQFjAA&usg=AFQjCNGVHbjKzqjmuBU-GpssbLsI8KIueg

Lte is using sim cards...at least on verizon's implementation.
[Epic 4G General] Txdaredvl:
I bet that will allow lte roaming on att/tmobile one day then. Dang.
[Epic 4G General] 063_XOBX:
Never. Different spectrum used and even then ATT and Verizon have no reason to sign roaming agreements when they are each others biggest competitors.

Texted while driving
[Epic 4G General] Kcarpenter:
Uh Huh...show me an implementation for LTE that doesn't use a Sim card for network authentication.

I mean GSM doesn't "Require" a sim either, that can be spoofed with hardware...just sayin.

I mean at least in for me, I have put 32 Sim cards in Verizon Pantec UX260 USB Aircards for some reason....
[Epic 4G General] jbadboy2007:
They can configure these phones however they want. We have 4g with no sim card. 4g is almost exactly the same thing as lte just different frequency that's all.
[Epic 4G General] Gersonian:
How about this article where they state what Sprint has said on the matter?
[Epic 4G General] Kcarpenter:
Ummm no...the entire protocol is different.

there are currently 3 popular 4g implementations.

HSPA+ with Extended Backhaul (ATT, Tmo)

LTE (VZW, Metro, non national carriers, EVENTUALLY ATT and Tmo on different freqs)

WiMax (Sprint)

The only thing these share is the 4G monicker. The technologies are enitrely different, the protocol is entirely different, the modems are entirely different.
[Epic 4G General] k0nane:
FTFY. AT&T's HSPA+ is very slow - there's no additional capacity or speed to be had.
[Epic 4G General] imtjnotu:
well...i wonder how true that article is...if it could just be a switch on the towers and a software patch it would be nice
[Epic 4G General] Esteway.619:
It would be nice cuz we paid a lot money for a 4g phone that some of us don't even have 4g like in San Diego I would be very mad cuz we where promise 4g by the end of this year
[Epic 4G General] Top Nurse:
I saw. Some company announcing a dual lte/wimax chip about 6 months ago. Since the modem controls these chips it isn't a far stretch to have software that will switch modems as needed.
[Epic 4G General] adrift02:
According to a seemingly knowledgeable manager I met with (he was down with rooting and xda lol) wimax is compatable with lte with a software update. But, honestly I doubt it.
[Epic 4G General] Txdaredvl:
That's what the 2 best buy employees said. Wasnt sure as most there are there for the money and know nothing. I asked if the evo had the LTE chip too as it wasnt listed and they said no but the Epic did. I couldnt imagine sprint leaving people hanging in today's phone battles. I will have to ask a store manager if they work there and see if they have any knowledge of it yet or if we will be able to roam. I thought LTE was near the same freq. for sprint and verizon with sprint just having the larger freq bandwidth due to LTE WIMAX.
[Epic 4G General] akijikan:
This came up back when WiMAX was first being introduced. I remember the CEO for Clear said multiple times that the WiMAX infrastructure was software "swappable" to LTE. It wouldn't surprise me if phones were the same.
[Epic 4G General] NoSoMo:
I haven't seen the specs for the size of the antenna in the Epic, but unless a specific length, it will not be able to get the signal properly. Unless Sprint has the ~825MHz frequency spectrum for LTE, I don't see it happening. The current antenna is sized for 2.5GHz, and typically antennas are sized at even fractions typically multiples of .5 of the actual wave lenth. (1/2,1/4,1/8,1/16)

So it may work out if the frequency is correct.
[Epic 4G General] Art2Fly:
I like to think of it like this... WiMAX is just a giant wifi hotspot while LTE is more like 3G except its a lot more powerfull... HSPA+ was just a software update and thats why t-mobile has the most (4G) coverage. 4G is a huge mess with a lot of companies implementing different (4G's) globally.... I read a very nice article on Engadget that outlined all of the G's and what they REALLY mean, you should go check it out. It describes everything in great detail, in fact this should be a must read for every member of this site. http://www.engadget.com/2011/01/17/2g-3g-4g-and-everything-in-between-an-engadget-wireless-prim/
[Epic 4G General] budderocks:
LTE is not linked to one frequency, it can be deployed on a variety of frequencies
[Epic 4G General] jbadboy2007:
Exactly thank you. This is a data connection just like our 4g and wifi. It is very similar and not that hard to convert any of it. I also saw the dual wimax and lte phone. We are not talking about the differences between cdma and gsm which those are way different. Data being data are almost the exact same protcol just different frequencies.
[Epic 4G General] NoSoMo:
No, but it's the frequency that's the Achilles heel of the current wimax implementation. Wimax and LTE are similar as it is. Sprint owns several 8-900Mhz Frequencies as Nextel uses them and I'm willing to bet if they DO switch to LTE, it won't be over night, and it will most likely be on the lower frequencies. It's not clear how sprint and clear will work with each other in the future, but I'm willing to bet that the new frequencies they own will be put to use now as they didn't have them when wimax was implemented.

It's all speculation until they actually announce and act on such announcements. It's not a secret that they've been testing the LTE setup in AZ, but I couldn't find anything to mention the frequencies they used. There were however peaking around 100Mb down and I saw a peak of ~72Mb up.
[Epic 4G General] lynyrd65:
I would say this is practically correct and this is why, it all boils down to spectrum.

Why does verizon have better 3g coverage than sprint? Frequency. The lower the frequency the better the range and the lower the theoretical limit on speed which is negligbly lower for now, (700Mhz-->700Mbps vs 2.5Ghz-->2.5Gbps), because we are nowhere near those limits.

The wimax and lte protocols are very similar in structure and theoretically could work seamlessly together. However, the frequencies they operate on, which are artificially set by standardization organizations, differ. By convention 2.5Ghz is the primary frequency used for wimax and 700mhz for lte but it doesn't have to be that way.

The coverage of a 4g network is quantified by the spectrum the operator chooses to use. The 2500mhz (sprint wimax) band is an especially undesirable band not only due to its high frequency (low range) but because of its proximity to the 2400mhz band which is used by consumer electronics such as microwave ovens, wifi devices, cordless phones and countless other sources of interference. 700mhz is a low frequency (with much better range). It is also a safe distance from any significant sources of interference.

Therefore the reason lte will win out (on att and verizon at least) is because of the low frequency these companies will use. Whatever frequency sprint chooses to implement lte or wimax on will ultimately make or break their 4g future.
[Epic 4G General] stevesprivateaccount:
A quick google search gives you pretty much all the information you need:

http://en.wikipedia.org/wiki/Comparison_of_wireless_data_standards

Frequency bands are based on what was contracted/purchased. As far as the radio technology, it looks like both LTE and Wimax can utilize similar technologies.
[Epic 4G General] charlie95113:
Possiblei

I got a twitter about a week or so ago from some android forum that took me to a page were SPRUNT anounced that all 4g phones on wimax will get an ota update for lte but who nows
[Epic 4G General] NoSoMo:
As stated in the previous posts....
[Epic 4G General] NoSoMo:
So it seems that sprint will utilize carrier aggregation to utilize all of their frequencies simultaneously. It's reported that there will by hybrid utilizations of all frequencies simultaneousness depending on what your phone determines is the best based on your location.

If such is the case, sprint wins hands down. Using the 8-900MHz frequencies for those hard to reach areas while those of us who pick up 2.5GHz will utilize it is brilliant. All of the frequencies will co-exist and basically it looks like the phones will balance based on what's available. LTE has been shown to be able to utilize several frequencies simultaneously, in sprints case it will be 8-900MHz, 1.9GHz, and 2.4x-2.6xGHz
[Epic 4G General] Whosdaman:
Actually...if you want to know the true. The Epic can support LTE. It is as simple as a software update. A new modem can enable the frequency on the Epic to pick up LTE on Sprint. Sprint would have to change to LTE first, but the Epic does support it. There is no requirement that says LTE needs a SIM card.

Check out Sprint's "Project Leapfrog"

If it's true, Sprint will easily have the best coverage in American, 3G and 4G wise.
[Epic 4G General] jbadboy2007:
Awesome thanks for the confirmation on this. To all the nay sayers ha ha ha rofl. Now I really won't need a new phone for like 10 years
[Epic 4G General] jbadboy2007:
Also I don't know why some of you would doubt the capabilities of our epics kinda dissappointing.
[Epic 4G General] Whosdaman:
Yeah, Verizon went with SIM card integration LTE network because it is cheaper. The expensive LTE network rollout combined with the expensive hardware of a LTE built in antenna is ridiculous.

The UICC SIM card was unique to Metro PCS, then Verizon follow suit. There was much debate on whether Verizon would go with or without SIM card usage.
[Epic 4G General] Top Nurse:
This is true, but just because the antenna is slightly off wavelength doesn't mean it won't radiate enough to pick up a cell tower. I can hook up a 15 meter tranceiver to a 2 meter antenna and still get workable 2 way reception. It may not be ideal, but it is definitely usable. Then of course they may have already forseen this and built into the device the capability to accept different wave lengths.
[Epic 4G General] Txdaredvl:
Does the 4 plugs on the back of the phone tell us how many antennas/radios we have. Thats assuming those are for external antennas.
[Epic 4G General] gTen:
Verizon is rolling out FD-LTE in the 700mhz band.

Sprint would be rolling out TD-LTE in the 2.5ghz band, Sprint is using 10mhz in the 2.5ghz band and they got 20mhz in the 2.5ghz band they can use for TD-LTE.

And yes, TD-LTE is a lot more similar to wimax then FD-LTE...(well LTE in general is similar to wimax too)
[Epic 4G General] insanity213:
Here is a slightly modified version of something I posted in another thread....

Granted on the downstream link both LTE and WiMax use OFDMA, their upstream characteristics are quite different. LTE uses a more complex method of multiplexing the upstream, utilizing both subcarriers on different frequencies and different timings. With such a drastic change in the return modulation schemes I would expect the RF transmitter in the 4g radios to be drastically different. I'm not exactly sure what the WiMax chips are capable of, but being how frugal chip makers have to be to stay competitive these days I wouldn't think a WiMAX chip could support the more robust LTE return modulation requirements with just a firmware update. You could probably overcome that limitation with some design changes on how the LTE tower is configured, but that would kind of defeat the purpose except for maybe using a more desirable carrier wave frequency. I would suspect that you could bastardize an LTE radio to lock onto WiMax (which is a looong stretch in and of itself) but going the other way around doesn't seem plausible. Maybe there's a nice suprise lurking in the WiMax chips Samsung uses in their phones, but somehow I doubt it. The only surprises I've found in the equipment I've played with so far have been quite the opposite of nice.

Modulation and time division schemes aside, doesn't Sprint/Clearwire's WiMax network operate in the 2.5ghz carrier freq range? If they implement LTE in the 800mhz neighborhood there would be issues with the wavelength the 4g antenna in a Wimax phone is tuned for. I'd have to understand the current antennas and do some math on the topic, but I'm pretty sure the wavelengths are going to be drastically different and would cause major issues on a relatively small mobile antenna.

Just my .02, but based on what I know about RF technologies it'll take alot more than a firmware flash to get current WiMax devices on Sprint's network to work on an 800mhz LTE network. And if they are going to use a decommissioned iDEN spectrum to facilitate this build out, it's going to be a while before they can even start lighting towers.
[Epic 4G General] jbadboy2007:
@insanity. Dude your wrong. Did you even read this thread before you posted or have you even researched lte wimax before. Sprint said they just have to software update 4g enabled phones for lte.
[Epic 4G General] gTen:
Again I repeat, sprint is going TD-LTE, not FD-LTE....800mhz is allowed for FD-LTE but NOT TD-LTE...TD-LTE runs in 1850 - 2620 mhz...TD-LTE uses OFDMA for download it uses SC-FDMA for upload..

While wimax on WiMAX 802.16e uses OFDMA, WiMAX 802.16m uses SC-FDMA as well..
[Epic 4G General] insanity213:
Whatever modulation standard they use, penetration in large cities and into office buildings is still going to be a problem at that high of a frequency. I wish they'd just trash iDen already and use the more desirable frequency.
[Epic 4G General] insanity213:
"Sprint Said...." Oh, well then. If they said a software update will improve my Samsung phone then it MUST be true....

They've said a number of things.... I'll believe it when I see it. Call me jaded if you will, but Sprint saying something about a software update to a Samsung device just doesn't carry much weight with me these days. I'd be curious to read more about the 4G radio in these things, but I'm really not buying anything Sprint says anymore.
[Epic 4G General] gTen:
They can't trash iden that quickly because they have contracts with clients...they recently swapping direct connect to cdma which is a step forward but it wont be till 2014 till its decommissioned.

That said they only have like 14mhz in the 800mhz band free..if they go FD-LTE they would still have the disadvantage of verizon using 20mhz in the 700mhz band..maybe in the future they will have a hybrid TD-LTE and FD-LTE network oreo...

I mean they can make TD-LTE work in big cities..they will just need more towers...simple as that...

Either way TD-LTE is what they are going thats 100%...and that means 2.5ghz band 20mhz....

Question is do they plan to completely dump the 10mhz wimax network or hope to up to to wimax-enchanced...which is a minor upgrade that will offer 2x speed and 40%-60% more efficiency.
[Epic 4G General] NoSoMo:
Sprint has lost 75% of the iden users to other frequencies so there are some frequencies open to fully implement leap frog
