why does 3g seem to be stronger than B26


Recommended Posts

Just kinda wondering why sprints 3g which is 1900mhz, seems to penetrate and have a stronger signal then B26?

B26 is turned on at low power, or just aimed lower. They optimize it later to provide better propagation. Aside from that, LTE will always drop out sooner than 3g because it requires a stronger and more stable connection.

Ahhh makes sense, thanks for the info. Any ideas on if they are still optimizing B26 around Lakeland Fl area.

Optimization is technically a never-ending process (they tweak the settings constantly), but initial optimization (that would noticeably improve range) can happen anywhere from the day after Band 26 is enabled on a tower to more than 6 months later.

 

Unfortunately, the process is so complicated that it requires a certified technician to do it and Sprint doesn't have enough to go around.

I was going to say...my local site has been upgraded to B26 for about a month now and it's reach is about the same as LTE 1900, but the way it is set up is everyone's camping on B26 so it's very slow.  Only single-band phones get B25, and it's much, much faster.  I'm thinking they tune certain areas at a time and continually optimize them.

 

I like that LTE is spectrum efficient, but sometimes I do wonder what EvDo RevB and higher would be like on Sprint as far as reach and building penetration.

For rural sites where interference is less of a concern, B26 should reach just a bit further than 3G on PCS does (1x included), bested only by 1x800. There have actually been a couple reports of B26 coverage somehow exceeding even 1x800 on some rural highway sites.

 

In urban/suburban areas, they do need to be more conservative, but I would still expect it to at least match the Ev-DO footprint.

 

If all surrounding sites are broadcasting B26, but a tri-band device still experiences either frequent drops to 3G or is sticking to B26 rather than shifting up to B25 or B41 during an active data session, then optimization is either not finished in that area, or wasn't finished properly.

Yeah I notice in my area B26 has about the same signal as B25 if not a little worse, can't wait for Sprint to finally optimize it. I've had my Nexus 5 since August and it's been the same no improvement, hopefully by the new year it will be optimized. It's quite funny actually I get no B25/B26 in my house but I am picking up B41 from a Clearwire site a few blocks away.

Very similar up in the Pottstown area, i rarely "see" LTE800 despite being surrounded by it. If i do transition to LTE800 it's typically for a few seconds before dropping to EV-DO. On a plus LTE2500 rollout seems to be picking up pace.

Here's a 5 minute video I just took of what optimized B26 looks like at the edge of signal. It beats EVDO, and also rivals 1X.

 

 

The "action" starts around 1:40.

 

What phone is that that picks up LTE so quickly when moving in and out of coverage? Or was airplane mode being toggled?

 

I swear the nexus 5's LTE scan timer is upwards of 20 or 30 minutes, very frustrating to hit a cell edge and drop to EVDO, returning to LTE coverage mere seconds later but having your phone camp on EVDO for the next 20 minutes.

Depends on the device.  If you have an active data session during the set scan intervals, it'll not scan for 4G because it'll disrupt the data flow.  That's why usually you'll stay on 3G often if you're streaming internet radio or have a background process using an active data session.  N5 is one of the few devices I believe that you can't modify the scan timer.

This is a galaxy Note 4. The reason it's picking up LTE so fast, is because that B26 LTE is the only good Sprint signal it's seeing. When its roaming, it's desperate to find any Sprint service. In an area that has a weaker B26 or stronger 1x/EVDO, it will take the normal ~3 minutes or so to pick up LTE again.

Incredible how Verizon has awesome signal at this location but Sprint just struggles ????

its simply because verizon has more towers in that location for some reason. also they run on 850MHz or something for 3G.

 

Also a properly tuned B26 site should easily best a 3G site. i mean heck i have read stuff on here with people saying they got 1x800 more than 10 miles from their location (and i have experienced it to) and i have seen my friends verizon phone on 4G KILL IT in terms of range.

Not necessarily. LTE is more fragile than 1x/EVDO, and in some places, EVDO may still reach further than Band 26, even when properly tuned.

Exactly....more towers. Sprint needs MORE towers....

Sprint's nationwide network site spacing is setup for 1900MHz, if its properly configured it can match Verizon's Cellular 850 setup. Verizon's primary LTE band is 700MHz which means they do not have to deploy LTE on every site they are located on, Sprint's 800 SMR LTE should closely match it in non-IBEZ markets once its fully deployed.

And the beauty is that almost every site will get 800mhz LTE, so take the PCS site spacing, and tack on 800mhz LTE.

VZW is deploying on all the sites they have here in Southern Illinois, the problem is twofold:

 

1. They have too many customers.

2. That grid has to be densified to handle getting LTE signal everywhere as well as adding on capacity.

    • Excuse my rookie comments here, but after enabling *#73#, it seems that the rainbow sim V2? requires n70 (I turned it off along with n71 - was hoping to track n66) to be available else it switches to T-Mobile.  So this confirms my suspicion that you need to be close to a site to get on Dish.  Have no idea why they don't just use plmn. To test, I put it into a s21 ultra, rebooted twice, came up on T-Mobile (no n70 on s21).  Tried to manually register on 313340, but it did not connect (tried twice). I am on factory unlocked firmware but used a s22 hack to get *#73# working.  Tried what you were suggesting with a T-Mobile sim partially installed, but that was very unstable with Dish ( I think they had figured that one out).  [edit: and now I see Boost sent me a successful device swap notice which says I can now begin to use my new device.  Sigh.  Will try again later and wait for this message - too impatient.]
    • Hopefully this indicates T-Mobile hasn't completely abandoned mmwave and/or small cells? But then again this is the loop, so take that as you will. Hopefully now that most macro activity is done (besides rural colo/builds), they will start working on small cells.

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, FWA Mobile in RVs in Walmart parking lots working where mobile phones need all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71, 90% 5g.  93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77 also with its shorter range.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
