Comparison of LTE vs. Current 3G coverage


Recommended Posts

I'm sure someone will be able to answer this for me and know that I'm not asking for an apples to apples comparison just what others have seen from thier experience or what they think. Right now I have a terrible signal inside my job. Recently it has got so bad that either my radio is disconnected or it's 1X. This maybe a result of ongoing deployment, but either way it has always been bad here. When the deployment is completed should I see slightly better coverage inside, worse, or the same.

 

Especially if you are going thru deployment now I would like to know what your experience is.

I had a similar issue at my work, its like working inside a lead box. With the tower I connect to being less than 1 mile away, I was continuously around -98 to -110 dBm in signal stregth. When the tower was updated, I saw a VERY SLIGHT improvement, not in bars or signal strength, but in the fact that all my calls were clearer inside the building, everyone I was talking to didn't sound like a robot, and I didn't have the "oh you have a voicemail, but your phone didn't ring" problem I used to have before the tower by my work was upgraded.

 

Now keep in mind, every situation is different and my experience may not be the same for you.

LTE-1900 will be worse than current 3g 1900. 3g 1900 will be improved by up to ~20%, however. If you get a new phone that has LTE-800 and the towers close to you are outputting LTE-800, then your in building LTE coverage could be better by a lot or a little than current 3g. LTE-800 is theory right now so we would have to go by similar deployments like Verizon LTE-700, which doesn't travel as far as their CDMA/3g 850, but does travel quite well.

Thanks that was exactly what I was looking for as an example.

Lost completely with your post..sorry :blink:

ok

 

Coverage will probably be something like:

 

NV CDMA-1x 800 > NV CDMA-1xA 1900 > Legacy CDMA-1x 1900 >= NV LTE-800 >= NV EVDO 1900 > Legacy EVDO 1900 > LTE -1900

 

NV LTE-800 might not travel as far as NV/Legacy EVDO-1900, or might travel further than NV/Legacy CDMA 1X 1900, not sure.

 

Network Vision LTE-800 might be greater than EVDO currently is.

My thinking is like this in order of highest priority:

1. Lower frequency travels further

2. CDMA travels further than EVDO. EVDO travels further than LTE.

3. NV increases coverage with RRU + antenna improvements

LTE requires a stronger signal than EVDO or 1x to work, so it will have slightly worse coverage than 3G does now. However, during the network vision upgrades, Sprint is installing radio technology that will allow them to improve signal strength by up to 20% over their current deployment. Because of this, indoor coverage and performance should see a slight boost on any current Sprint phone after the upgrades.

 

Sometime after the initial upgrade, Sprint is then going to come through and enable 1x on the ESMR band, which is on a much lower frequency than their current PCS 1x. This will allow dramatically better in network coverage and signal strength. This will only affect 1x and will only work on phones released after the EVO 3D (sans iPhone 4 or 4S). Also, 1x only carries voice and 2G speed data, so 3G won't get any better after the initial upgrade.

 

Even further down the road, Sprint will deploy LTE on ESMR. Then, 4G will have better coverage than 3G by a significant margin. This will require new devices to access though.

No, be careful with that prediction. LTE 800 may provide broader coverage than EV-DO 1900 does, but there is no guarantee. And "significant margin" is probably too strong.

It might also be relevant to note that we might not see the complete NV boost in signal strength until downtilt is adjusted back to pre-NV levels. I have heard it mentioned several times on here that due to the incomplete nature of the build out to this point, that most panels have little downtilt, in an effort to maximize area covered. I don't know if any NV buildout is far enough along to have had the downtilt adjusted.

The panels have 3 separate downtilt adjustments. PCS EVDO/1X to mock the legacy network, 800SMR, and PCS LTE. If by some miracle, the tower crew fires up 3G when they fire up 4G. They would of course have to adjust the PCS EVDO/1X downtilt to be somewhat like the previous legacy equipment in order to prevent interference with adjacent legacy network cells. They can do whatever they want with the 800SMR and LTE downtilt adjustments of course.

 

Your voice and texting issues could probably be solved when your local site becomes 3G activated (meaning legacy is shut down) due to the newer panel and RRU benefit. But I bet it will really make a difference when 800SMR is activated in your area. It might possibly be activated right now with that goofy Utah SID or maybe even the Tampa SID. You'll have to test that 800SMR PRL with all SIDs activated to find out.

Are you mocking the legacy network?

Ah, good to know. I didn't know they had separate down-tilts for all 3.

Elaborate please...

 

800SMR is actually what I have been looking forward to the most.

Look in the download section here. No LTE in that prl on qualcomm devices though.

It deserves it. Its been mocking him for a longggg time.

    • Has anyone checked Verizon n77 in areas with more than 100MHZ active? This spectrum has been fully available since August of last year.  Of course they are not typically using SA.
    • I updated my other s21 ultra factory unlocked to the latest firmware... It behaves like the S24 Ultra n38 or n41 depending on 80 or 100MHz or their nr- arfcn.
    • I see everything correct. The two ARFCN's you mentioned earlier and they idenitify as n-41.  using 4.832b SCP. Only using one TM SIM.
    • I posted this in the Nebraska Premier thread last week, but just wanted to share in this thread the progress that T-Mobile has made in filling in the great coverage gap known as Nebraska. Between late last year and this year, they have added 28 new expansion sites filling in the coverage hole, plus 11 Sprint site conversions in eastern Nebraska and far western Iowa. Notably, in the last month n41 coverage was added on over a dozen expansion sites in western Nebraska that were added to the network last year. For comparison, here is the very first map that I created in October of 2022 after we noted expansion sites outside of Sprint conversion in Lincoln and Omaha. It doesn't show any western parts of the state, but just know there was nothing besides roaming coverage and a little B12 coverage leaking down from South Dakota to the west of Valentine, NE.
    • Sent a copy of my DB in an e-mail just now.  Couldn't leave the house today but can hopefully get a screenshot when I'm out on another cell site tomorrow.
