How does 4G coverage compare to Evdo / 1x


Recommended Posts

To answer part of the OP's question, yes 3G EV-DO (And 2G 1X) speeds should dramatically increase with NV if they were previously below 600kbps. Sprint is connecting faster backhaul to all of the NV equipment.

so is LTE in rural areas like mine where cell spacing is in the 5-10 mile range going to be lilly pad style or what?

My guess would be to a certain degree this will be the case, but that the 800LTE will mostly fix this problem.

1xRTT is not 2G, it is a third generation technology.

It depends on how the towers are engineered and optimized. I don't know what the likelihood of blanketing an area with LTE 1900 coverage is with that cell spacing, but it might be possible with tall enough towers and absolutely no downtilt. People like AJ and Robert would be able to give you a better response.

Kind of. cdmaOne and not CDMA2000 is 3GGP2's implementation of 2G, that is true. In real-world performance, however, 1xRTT and 1xA are much slower than all other 3G standards (Ev-DO r0, Ev-DO rA/B, UMTS/WCDMA, HSPA) as well as speedier 3G transitional standards that are frequently erroneously referred to as "4G" (HSPA+21, HSPA+42, 802.16e Wi-Max, LTE r8/9). To the end-user CDMA2000 1xRTT is akin to other 2G transitional technologies like GPRS and EDGE. So I generally class 1xRTT as 2.5G and 1xA as 2.75G. I guess one could round those up to 3 ;)

 

I certainly wish Android's notification bar labeled 1x as such instead of having it share the same "3G" label with Ev-DO/eHRPD, and just labeled Sprint's current LTE r9 as "LTE" to distinguish it from the upcoming true 4G LTE-A r10+ standard.

Can anyone answer this question? I use an airave because i used to have terrible signal in my home but recently i unplugged my airave to check my signal since 3g has been rolling out on 800 mhz and i had full signal but it was on 1x and whenever i switched to 3g i had 2 bars compared to 5 on 1x. What exactly can be causing that and when network vision is complete will i have the same signal on 3g and LTE as 1x now?

It's because EVDO is on 1900Mhz and 1x is on 800Mhz. Your voice/slower 3G data coverage is greater but you "high speed" 3G data has worse building penetration. Eventually LTE will have the same signal as your 1x does currently.

That's fine, you should just stick with voice on 1x, and use WIFI when at home instead of 3G/LTE.

Ok thanks! I'm good with my 20 meg download on wifi. i just want to know when i can fully take advantage of my unlimited plan ;) and eventually have better than my wifi speeds.

You have it made now! Full voice and unlimited in home wifi... What I am hoping for if they ever upgrade my GMOs out here.

 

As far as "using" your unlimited... Remember, your home Internet is unlimited, too... Only difference is the cellular data is more valuable as a shareable resource with your neighbors...

You probably will never get more than your home WIFI speeds, but think about it when you're mobile and getting those same speeds.

 

I have Verizon FiOS at home and get 2x LTE speeds, but when I leave my house, I get to enjoy 15-20mbps down on my way to work, which is perfect.

In my opinion if it uses CDMA it is 3G. Yes, that means that you have to include HSPA in that group as well. I would also say that LTE (even the non-advanced kind) is 4G because it uses OFDMA.

I've noticed that when 1900 voice is around -90DB 4G is around 100-115 or there is no 4G.

 

CDMA1X is measured via RSSI.  LTE is measured via RSRP.  The two measurements are not exactly comparable.

Ah a article written by you lol. But it'd be nice if the RSRP could at least match the RSSI strength wise. It sucks to see that 3G can reach so far, but 4G doesn't go AS far. On the same frequency. But I know things will just get better as time goes on

The numbers mean essentially nothing.  They are all relative.

 

But a less robust airlink is the price you pay for faster data rates.

the numbers don't, but the speeds do.  I'd rather pay for something I can count on than something that you can hardly count on. There shouldn't be "a less robust airlink is the price you pay for faster data rates." It should be equal with the type of technology and hardware that is being deployed. But i love it lol

Nope.  Wireless technology is not magic.  It cannot solve all problems, and there is no such thing as a free lunch.  You were practically just out of diapers when I was in college and started using nascent wireless data services in the year 2000.  Max speeds on IS-95 CSD were 14.4 kbps, but it was just as consistent and robust as voice.  Now, we have data speeds 1000x that, but the price we pay is less coverage and a more fragile airlink.  That is the tradeoff.

I know that. But things will get better over time as they always seem to even through problems. Breakthroughs  happen all the time.

While that is certainly possible, I wouldn't count on it because there's only so much you can do. I think what needs to happen is that the operators need to rethink their networks and space them better (or use more small cells) to make up for LTE's fragility.

I agree about tower spacing or using small cells to help out. Where I live, 3G just barely reaches between towers. I will drive along sr16 and go from 6 bars to zero bars and 1x to a small blip of Primeco roaming for maybe a couple hundred feet to another 3G signal with 2 bars and back to full shortly after. It happens in quite a few sections of the city.

so are they upgrading the 3g as well??? to maybe fill gaps....and does it have a wider range.....say 2 mile circle vs 1.5 mile for LTE....those numbers are just made up distance wise....

 

 

 

Yes they are upgrading 3g also.. "new" 3g speeds are typically 1.5 Mb/s down to sometimes even 2 Mb/s down.. which is much faster then old ( legacy ) 3g..  Sprint is upgrading 99% of sites.. They aren't just adding 4g LTE, they are actually changing evertything.. so 3g get better, 1x ( Voice ) gets upgraded because its going to be on 800 Mhz in most places, LTE will also be on 800 & 1900 Mhz ,  and 2500Mhz TD-LTE gets added to most of the 38k sites now according to the most recent Sprint earnings conference..

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
