SignalCheck - Android app to monitor your 2G/3G/4G LTE signal strengths

Recommended Posts

Mike and others,

 

Other apps such as Signal Detector and LTE Discovery also get null GCI, GCI & PCI, or RSRP from time to time.  Most frequently at the start or end of a connection to a site.  I just consider these as incomplete.  Occasionally you will also get GCI of FFFFFFFF, usually just one record at a time.  Rarely a sector will only broadcast GCI FFFFFFFF for a short period of time.

852 entries deleted. I didn't realize I'd encountered that many clear sites, or even b41 sites xD.

Hence my hope that most people would opt to scrub it away. Did the prompt seem clear enough? Adjusting the wording took longer than coding it.

 

Many of yours were probably bogus duplicate entries of B25 and/or B26 sites that had the wrong PLMN showing.. plus with one entry per unique GCI, a typical site could have 6 such entries (3 B25 sectors, 3 B26). The garbage piles up quickly!

It seemed clear to me. There was one thing I found odd, the order of the choices. Normally you see it as: yes, no, maybe later (at least in my experience). However your way probably helps cut down on people accidentally clicking yes and then getting angry with you :P.

It's not my way, it's Android's way -- buttons are coded as "Positive", "Negative", and "Neutral".. the OS decides what order they go in. Somewhere around Android 4.0 they switched the order around. I just go with the flow!

That would be great.  AT&T seems to use patterns of 8 here when it comes to the PSC, i.e. 32, 40, 48

 

I haven't looked at the PSC stuff yet for a pattern but here's what I have from my notes (figured I would share in case others need it as well)

 

310-410 AT&T - 1c = 1 carrier(channel), 2c = 2 carrier, etc.

 

HSPA Pattern

 

CID 11961 belongs to site 1196.  The 1 is the sector/carrier designation.

 

The sector and carriers are as follows for the first 3 subset of HSPA channels.  

 

1=1c, 4=2c, 7=3c of the Alpha sector

2=1c, 5=2c, 8=3c of the Beta sector

3=1c, 6=2c, 9=3c of the Gamma sector

 

2nd subset of HSPA

 

In most cases 4000 is added to the site number, in rare cases I've seen 4600 added.  1196 would become 5196.

 

The sector and carriers are as follows for the second subset of HSPA channels.  

(sectors 4-6 seemed to be skipped)

1=4c, 7=5c of the Alpha sector

2=4c, 8=5c of the Beta sector

3=4c, 9=5c of the Gamma sector

 

In summary, 11965 would be Site 1196 Beta C2 and 51969 would be Site 1196 Gamma 5c.

 

 

LTE Pattern

 

Last two digits of GCI to determine the band

 

0F, 10, 11 - B17

16, 17, 19 - B4

08, 09, 0A - B2

00, 01, 02 - B5

84, 85, 86 - B17 indoor DAS

64, 65, 66 - B17 wide area DAS

 

Example GCI - 02C3CC0F  - Remove the sector ID and convert to DEC - 02C3CC becomes 181196.  The first two digits are the market/region ID.  1196 again is the site ID and matches to the HSPA side of the site.  Occasionaly some sites will use the 4c,5c HSPA site IDs with the 4000 added to the number.  I've seen this on older Band 4 upgrades with RRUS11 B4.  I've seen them going back to the original site IDs(non-4000 incremented) when they've been converting them to B17/B4/B2 sites with the AIR21 B4A/B12P antennas with RRUS12 B12 with the A2 B2 backpack.

Uh, Samsung, the word is spelled "enginerring."  That screen is almost certainly in error.

Your enginerring screen is showing PLMN "311-49" which really means 311490 but Samsung can't get their act together. That indicates a Clearwire B41 site. However, your Note 4 is reporting PLMN 310120 to Android, which is the default for Sprint.

 

Improper PLMN reporting is an issue that plagues most Samsung devices, and unfortunately there isn't anything I can do about it except yell at Samsung and hope they fix it in a future software update. SignalCheck is not indicating B41 because the phone is not providing correct information to the app.

 

Samsung did release a tool that has fixed issues related to SignalCheck for other users called "Refresh Customization" you can try. I do not know which devices it is compatible with and some people warn of settings getting reset, so use at your own risk: https://play.google.com/store/apps/details?id=com.samsung.refreshDevice

Sounds like a juicy rumor! The weekend ends today, hmmmm.....

The most anticipated software update of your life is finally here.. SignalCheck 4.261 has been released into the wild! It has been pushed to Google Play and should be available within the hour. This is a significant update but my beta crew did a great job so it should be stable. One major bug I am still aware of is the lack of Alerts for those running Android 5.0 (Lollipop) -- I'm still working on that. The option is in the app, but the Alerts never play.

 

A lot of the details have been discussed over the past couple of weeks, but below is the full changelog, roughly prioritized.. as always, thanks for everyone's support!

 

Improved Sprint LTE band 41 identification, including new 8T8R sites.
Resolved issue with PLMN 311490 always showing for Sprint LTE band 41.
Resolved issue with Sprint LTE PLMN failing to update properly.
Band 41 identification is drastically improved.. and "drastically" might be an understatement. It was terrible before, and that's putting it nicely. The only remaining B41 issue appears to be with Samsung devices; many (including the Note 4 and Galaxy S5) are not reporting the proper PLMN, so the app is unable to recognize Clearwire B41 sites. On these devices, users will see a different GCI pattern that matches the Clearwire numbering scheme for their market. Hopefully Samsung fixes this sooner rather than later.
 
Users who have any Clearwire B41 entries in their Site Log will be prompted to delete them the first time they launch the app after upgrading. This is strongly recommended. The B41 identification in previous versions was so unreliable that there is likely a significant accumulation of unreliable data in your log. If you answer "Yes" or "No", you will not be prompted again, so choose "Ask Me Later" if you want to think about it until the next time you bring the app into the foreground. I understand that many of you may have saved some B41 site notes, but again, it was so unreliable, I suggest that you scrub it out and move forward knowing that everything from this point forward will be accurate.
 
Sprint LTE band 41 sites that were not Clearwire sites will share user notes with co-located B25 sites. (Pro)
Thanks to the detective work of S4GRU users, 8T8R sites are now identified within the app. SignalCheck will now link the site notes for B25 and B41 sites, but it requires a bit of confusing explanation. If you have B25 notes already saved for a site, and connect to the B41 side of that same site, you will see the same site note. The same is true in reverse -- if you have a B41 site note saved, once you connect to B25, the note will be linked. However, if you already have separate site notes for B25 and B41, those notes will remain separate UNTIL you edit either one, at which time it will overwrite all notes for that site. Please ask if you have questions about this; I realize it might cause some head-scratching, but it's really a great feature and will save everyone some time as 8T8R construction progresses.
 
Added option to display LTE and GSM neighbor cells. (Pro)
A neighbor cell is another sector in range of your device that is not serving the active connection. For LTE, neighbor PCIs are shown; for WCDMA, neighbor PSCs are shown; and for GSM, the PLMN, CID, and LAC are shown. No other information about neighbor cells is available, so I am not able to absolutely confirm which specific LTE or WCDMA sites the neighbor cells represent. However, I decided to take a stab at it for LTE and display the site notes associated with a site that it MIGHT be. If there is a note saved for the given PCI on the currently connected TAC, the note is displayed with the neighbor cell. There is a margin of error with this; you may be seeing a neighbor PCI that is on another TAC, so the note displayed may be incorrect. There should be a decent distance between these sites, so it should be clear if you are seeing a note from a site that is not in the vicinity.You may see the same PCI shown several times; this is most likely the different bands broadcasting from the same sector.
 
Added options to hide disconnected or unavailable connection types. (Pro)
With the addition of neighbor cells, the information display was spanning beyond a single screen, so it only made sense to include this now. There are a few different options; "Hide All" hides anything that is not conected, "Only Disabled" only hides disabled connections, "Only Wi-Fi" only hides the Wi-Fi display when it is not available, and "None" shows all connection types all the time.
 
Added Site Log fields for strongest signals and the locations they were received. (Pro)
After running the log for awhile, you should be able to plot the information from these new columns to get a good idea of where the site is. The signal strength, latitude, and longitude are recorded.
 
Added display of frequency class for recognized LTE bands (i.e. "LTE 800") on the main screen.
This is pretty self-explanatory; makes it very easy to see the impact of a tri-band network.

 

Sprint LTE band 41 sites that were owned by Clearwire are now marked with an asterisk on the main screen.
Eventually, these sites will be the execptions, as construction progresses on native Sprint sites with 8T8R equipment. Again, a Samsung bug prevents proper Clear B41 recognition on many devices, so nothing will be shown on those.

 

Added display of primary scrambling code (PSC) for GSM sites.
I'm not sure what this is, but I figured out how to get it, so I might as well display it. WCDMA neighbor cells are only identified by their PSC.
 
Resolved issue with disconnected Wi-Fi connections showing -127 dBm signal on Android 5.0.
Lollipop has introduced some changes that impact the app; please report any issues you discover. Alerts are still not working for Lollipop users. It looks like the public launch will be on November 3, so I will hopefully have this fixed very soon.
 
Resolved issue with null GCI and TAC values appearing in the LTE site log. (Pro)
I thought this bug was squashed, but apparently not -- please let me know if the issues continue.
 
Resolved issue with Wi-Fi connections displaying speeds of 0 Mbps on some devices.

The Wi-Fi speed will now be hidden if it is invalid.

 
Changed user site note prompts to capitalize the first letter of each word by default. (Pro)

This was driving me crazy, very happy to have found how to do this!

 
Resolved issue with missing last_time values in the Site Log. (Pro)

The "last_time" column could be null under certain conditions, but that is now fixed.

 
Resolved issue with stale 1X information displayed after connection is lost. (Pro)

The BSL and/or graphic meter would "stick" in certain conditions.

 

Added indicators for Free Mobile UMTS bands 1 and 8 and LTE band 7.
International provider based in France. I will add band identifers for any networks as long as someone can provide me with a site identification pattern to do so.
 
Updated provider database.
Minor update, mostly to international providers.

 

SignalCheck Lite (the free version) will be updated next week, I realize it is a couple of versions behind.

Well I'm in your hood now, in STL. Near Ferguson (since everyone now knows when that is). I don't have it in Madison though. Just never got prompt, didn't know if we were all supposed to see it.

You will only get the prompt if you have any Clearwire B41 entries in your Site Log the first time you open the app after updating. If there are no entries, there is nothing to clean up. If you have a S5, I doubt you will be prompted, because the S5 can't identify Clear B41.

 

Although now I'm wondering if there will be an issue down the road when someone who isn't prompted then saves some Clear B41 entries.. hmm.. uh oh! EDIT: I must have already thought of that, I checked the code.. that won't happen. :)

Can you work it to re-prompt and re-clean the entries every 3ish months or something?

      I recently went on an 8 day cruise from NYC to the Caribbean that stopped in Turks and Caicos, Puerto Rico, and the Dominican Republic. My first stop was Grand Turk and there I opted for the free roaming. My S9+ automatically connected to Flow's (Cable & Wireless) LTE network where I received speeds of around 120kbps on average with boosts of up to 150kbps. Something worth noting is that on speed tests, the server prefers to default to Sprint's Miami server as opposed to local servers. Speeds were more than adequate for any amount of web browsing and honestly felt much faster than in reality. It helps that using Chrome will save you data by not loading pictures on certain sites unless you click them.
      In Puerto Rico, I connected to Band 13 on the way into the port in San Juan but once I was in the city, my phone never left Band 41. While the phone was usable, speeds remained significantly lower than what I've come to expect from 3xCA in the mainland U.S. Data speeds peaked at around 25-30Mbos but on average were in the 5-10 Mbps range even on LTE+. Signal remained strong everywhere though. 
      Finally in the Dominican Republic, I entered in Amber Cover which is in Puerto Plata. My phone latched onto a weak Band 2 LTE signal in the port from Altice (called Orange Dominicana in SignalCheck). I had trouble loading pages though. Once off of the ship and out in the open, I had a much stronger signal which allowed me to browse the internet without a hitch. Because it was the last day of my trip, while at the beach I decided to purchase the 24 hour high speed pass for $5. My speeds went from 120kbps to 65Mbps in less than 5 seconds. In some areas speeds were slower, particularly at the port where it struggled to break 2Mbps. Now, back on the boat my phone is flipping between weak Band 4 LTE and overloaded Band 5 HSPA+ from Claro (called Verizon Dominicana in SignalCheck Pro). Here is the difference in speed from before and after purchasing the high speed pass.

      Sprint 4G Rollout Updates
      Tuesday, January 31, 2012 - 7:46 PM MST
       
      Since last fall, there had been talk of a Samsung Galaxy Nexus launching on American carriers other than Big Red. Sprint has finally announced several weeks ago that it is the another vendor slated for release in the U.S. Suffice to say, many of us out there, especially those adverse to heading to Verizon and paying its premium prices, are excited about the impending release.
      The good news is that Google could be working on an updated version of the Galaxy Nexus. It has unofficially been dubbed the Galaxy Nexus Plus. There is much anticipation that it will be released before Sprint turns on LTE this summer. It’s not the first time an OEM has refreshed a device and re-released it to the market place, which works to our advantage. It’s rumored that the new Galaxy Nexus will have either a 1.5 or 1.8 GHz Texas Instrument OMAP4670 dual core processor. This would be a significant upgrade from the 1.2 GHz dual core processor found in the current Verizon version.
      We don’t know anything about official specs, but it’s also rumored to have an 8 MP camera. This is a noteworthy upgrade to the 5 MP shooter on the Verizon model (which has been lauded by many techies). We already know that the Sprint model will come installed with Google Wallet, per previous announcements. Some rumors also point to a beefier battery as well. The phone should have all the other features that’s on the current Galaxy Nexus, so now all we have to do is wait.

      Sprint 4G Rollout Updates
      Monday, June 25, 2012 - 4:27 PM MDT
       
      As technologies advance, the equipment to use the technology must advance as well. With the upcoming release of 4G LTE in our area (Houston), new equipment will be required to be able to use it. Although Sprint will have numerous data devices to handle the usage by the end of the year, only the Sprint Tri-Band Modem will be available at the rollout of the 4G LTE service.
      Due to the enormous dependence my business has on accessing data in a mobile environment, plus the great increases in data speed available with 4G LTE, this makes getting access to 4G LTE imperative to me. I depended heavily on the Sierra Wireless data devices when I started this business 7 years ago for my source of a reliable method of mobile data transmission. This relationship continued on until the release of the original Hotspot with the 4G service in my area.
      At one point, I was so displeased with past models, that I had sworn I would never buy another Sierra Wireless device as long as I live. This conclusion was reached after having numerous issues with previous hotspot models. There were so many problems that it seemed as if the device was never even tested on the networks it was to be used on. Also Sprint actively blocked reviews of the device, likely to not hinder sales in spite of the problems.
      My need for a new device with both WiMax and LTE capability outweighed my outright dislike of Sierra Wireless products. I proceeded against better judgment, and the Tri-Band modem was ordered even though the possibility of getting a substandard unit once again was always at the forefront of my mind.
       
      On with the show
       

      The official part number of the Tri-Band Modem is 803S. Along with the modem, I also ordered the SSX7077-V desktop cradle. I had to dig through a lot sites to find the information necessary to make this decision for my business. Much to my surprise, even though I was told the cradle was not available yet, I got a Sprint telesales person who was able to use the part number and find they had it in stock.
      Upon arrival I unpacked the unit and cradle...while holding my breath. The device that came out of the box was a pleasant departure from the previous Hotspots I had owned. Above is a picture of the device as it was shipped with all components. There was a small user guide as well but to get the real instructions the user guide must be downloaded from Sprint.
       
      Gone was the one piece blow molded plastic case which allowed no air circulation and caused the prior Hotspots to overheat quickly. Although the display is still too small for my aging eyes (it is actually the same display size as prior units) the change to the case makes it much easier to see in the interior of my van where the device will mostly be used.
      In this picture of the front you can see that there is a new button arrangement as compared to the older Hotspots. Also in the picture is the USB cable for use with the charger or to connect a computer, the AC to USB adapter, the battery and the battery cover. I opened the cradle, which was surprisingly inexpensive, and was delighted to find an additional AC to USB adapter which meant the cradle could be left in place without having to move the adapter around.
      As you look at the modem from the side you can see the antenna ports (the covers are open), the USB connector in the middle and the slot for the memory card. The round hole just right of the left antenna port is the reset button for the unit.

      Here is the same view with the battery and cover installed. Notice that the SD card slot is covered by the
      battery cover.
       

      The opposite side has two switches. The one on the left is a WPS setup button while the one on the right is a slider to mute the unit.
       

       
      The unit sits nicely in the cradle and looks to me to be a solution to help keep the USB port for the charger/interface cable from failing. This has been a major issue with the prior Hotspots. The case of the unit also helps support the USB port to take some of the load off of the circuit board.
      It took quite a bit of digging on the Sierra Wireless site to find out that the antenna ports are for the 4G WiMax band only. The cradle contains 2 5dbi omnidirectional antennas to allow full use of the WiMax network architecture.
       
      Initial testing

      The initial testing of the unit looks promising. The antennas in the cradle for 4G WiMax actually seem to get 3 – 5dBm gain in all conditions tested. The new unit has the ability to search the other bands for signals while staying connected. This allows less downtime between band changes. I notice a lot less disruption when switching bands.
      This unit has better reception on 3G and 4G WiMax than the previous hotspots and even the U600 USB modem I use as well. 4G WiMax is able to connect quickly even at 10% and the cradle has improved stability of WiMax and decreased ping times. For a short time I had access to Sprint 4G LTE as they were testing the towers in my area. The speeds were incredilbly faster. A 10% 4G LTE signal averaged 8.12Mbps download and 1.85Mbps upload. An 80% signal was able to get 35.8Mbps down on my best test and 22.1Mbps up.
      The upload speeds was very unexpected, and much higher than Sprint LTE smartphone devices have reported. This is likely due to much stronger transmit capabilities of the hotspot. I also discovered that when the modem is tethered the cable limits the bandwidth to approximately 20Mbps total speed. It will be interesting to see how it works in the 12 to 14 hour days of hot Houston Weather.
       
      First week in the field
      The Tri Band Modem got pressed into service a little quicker than planned, as my main unit went down with a bad transmission and the U600 USB modem with a Cradlepoint that was in this unit appears to have been damaged by the wrecker’s radio which runs on the edge of the WiMax frequency at 5 watts. The units have been sent in to determine cause of failure and for repairs but I think next time I will make sure all electronics are powered off before getting that close to a transmitter (OUCH!!).
      I am running the same routes in a rental van with the Tri-Band Modem that I normally use the other units on. There is less downtime in the signal gaps I am familiar with and areas where I have had signal problems in both 3G and 4G WiMax are much improved. I have yet to encounter any more 4G LTE signals but am looking forward to the service coming online soon. The unit seems to be running hotter than I would like with a fully charged battery but is actually cooler that the previous Hotspots. The temperature is supposed to soar over the next few days without the cloudiness we have had this past week. So it will be interesting to see if the overheating problems of previous models still occur.
       
      Week 2 – The True test
      The unit is getting worked really hard this week with temperatures outside up near 100 degrees. The GPS is useless with this kind of sun load as the unit will overheat if left in direct sunlight (as the instructions state) in about 20 minutes. The good news is that this is about twice as long as my original Hotspot will last. How anyone can make a unit that requires a clear view of the sky for GPS but can’t handle sunlight is beyond comprehension. A quick check of the Tri-Band’s temperature specs shows that the unit is only rated for 95 degrees. The prior Hotspot was rated well above the century mark but couldn’t even handle 90 degrees for any length of time. The crappiest laptop on the market will handle 105 degrees plus all day long. The true test will be my afternoon calls when the temperatures are high. Battery life has been about 8 to 9 hours which is far better than the prior Hotspots.
      The unit started overheating one afternoon. I can’t say I’m a bit surprised at that, but what is surprising is that it will run steadily as long as the air temp is below 98 degrees. This is a first for Hotspots as they always overheated well before the rated temperature spec. The bad news is the crappy overheat shutdown doesn’t turn off the unit before damage starts to occur, nor does it turn the unit off completely.
      Removing the battery cover seems to help air circulation and overheating some. The button lights are flickering after one overheating but the unit seems to be working fine other than this. It will be interesting to see what happens when it really gets hot here.
      According to the specs 4G LTE takes the least amount of wattage to run so it may not overheat as fast when using 4G LTE. I had the chance to try the modem in the old school 3G EVDO mode as one of my locations is 40 feet underground and that is all that is available at this location. I shut the unit down after 30 minutes as the unit was so hot you could barely handle it even though the temperature underground is around 70 degrees. I would not recommend trying to use this for any length of time if you want the Tri-Band to not overheat!!
       
      My Opinion
      Although Sierra Wireless has made some major improvement in the 3rd generation Hotspot, this is still a unit for the casual user. It is not designed to handle heavy use or outdoor summer temperatures for any length of time. It will be going in my climate controlled cabinet to protect it from the heat next week. I will let you know how it works when the temperature stays below 85 degrees. The improvements in connectivity, reception and stability are worth the investment. As long as you know and adjust your usage for the limitations of the unit.

      Sprint Nextel revealed their second quarter 2012 corporate earnings in a conference call to their investors today and S4GRU was covering for news on Network Vision.
      Network thinning of the iDEN network is complete, taking 1/3 of Nextel towers off air. The Nextel network was built to support 20 million subscribers, but was only supporting 4.4 million subscribers, so it could easily be thinned without [much] noticeable change in street coverage. Sprint also converted 60% of the Nextel subscriber loss into their Sprint subscriber base. Interestingly, they stated that Verizon has been the biggest poacher of subscribers leaving Nextel, grabbing 50% of former subscribers in the last 4 1/2 years. In that same timeframe, Sprint has grabbed 25%, AT&T 20% and T-Mobile 5%.
       
       
      On the Network Vision topic:
      4 additional cities will launch, including Baltimore, by the end of August.*Edit* Cities were disclosed VIA press release following the conference call. They are:
      Baltimore, MD Gainesville, GA Manhattan/Junction City, KS Sherman-Denison, TX  
      Over 2,000 sites are currently online with 12,000 sites to be online by the end of the year
      Network Vision towers are seeing 10-20% additional voice minutes usage per tower, overnight after activating Network Vision. This will equal roaming savings for Sprint, and ESMR will only increase that savings.
      CEO Dan Hesse confirmed that Sprint will be releasing the Motorola Photon Q "in the very near future." It will be a QWERTY slider "with robust business and consumer features." It will also be sporting world phone capability.
      Several hundred Network Vision sites are waiting for backhaul, and will turn on when the backhaul is installed, several hundred more sites have birds nesting on them and Sprint won't be able to turn them on until the birds leave, according to the conference call.
      Sprint sold 1.5 million iPhones during the quarter, even though other carriers saw slowing of sales with rumors ramping up that the new iPhone would support LTE. 40% of the iPhone sales were to new customers. They also stated that iPhone customers require less customer support and are expected to churn less than customers on other phones.
      Mr. Hesse confirmed that Sprint is not looking to change plans in the near future.
      Things are looking up for Sprint. This quarter saw their highest ARPU and their lowest churn rate to date. They posted a larger loss than Q1, but beat their revenue goals for Q2. For more detailed financial information, check the source link below.

      Ericsson RRUS31 B25 + RRUS11 B26
      These are the newest and greatest remote radio units to come from Ericsson. 

      The new Ericsson RRUS31  B25 should be fairly distinctive compared to the earlier RRUS11s and now the RRUS12s being deployed by ATT and Verizon. One of these new RRUS31s can do the job of two earlier RRUS11s thus reducing deployment costs for Sprint and complexity in deploying new sites and making it easier for users to spot as there are now 4 jumpers coming out of one RRUS31 rather than two from each RRUS11 that Ericsson originally deployed. 

      All future deployments will be utilizing the new Ericsson RRUS31s. In addition Ericsson are sending crews to their original deployments and swapping out older RRUS11s for these new RRUS31s due to the aforementioned fact that one RRUS31 can do the job of 2 RRUS11s. Weight savings will be significant at sites where there are 4 or 5 RRUS11 B25s that can be replaced by one or 2 RRUS31s. The Ericsson RRUS31 deployment project is known as the 65 Mhz Project.

      Ericsson High Capacity / 4x4/2 MIMO Deployment
      Note the additional antenna + PCS radio.
      Previously Ericsson utilized additional PCS radios and used RF combiners for high capacity setups where they utilized three or more PCS radios. This new setup will utilize a completey new antenna + radio set just like Samsung and run 4x2 MIMO on the LTE antenna / radio set.

      A standard Ericsson Network Vision 1.0 site with 3 RRUS11s where two are dedicated to PCS and one to SMR.  

      This type of setup is no longer deployed or utilized in new sites. Existing sites will be slowly converted to newer RRUS31 B25 via the Sprint 65 mhz project.

      3 or 4 PCS RRUs are present for a total of 4 or 5 RRUS11s per antenna.

    • Something else I forgot to mention, the V40 is enabled for calling plus on LTE and wifi, and it has been working very well so far. I usually keep it disabled for WiFi, since my WiFi is a bit weak in some parts of my house.
    • A little anecdotal note on radio performance. I am currently a location with known poor coverage. We have 3 new phones - iPhone XS, XS Max, and LG V40. The iPhones are having no trouble picking up a usable LTE signal inside, but the V40 only connects to 3G unless I go outside, and the data is barely usable. It is band 26 LTE (800MHz) based on Signal Check on the V40 when I go outside and pick up the LTE signal. Actually now that I think about it, the V40 is probably on 1xrtt inside, not 3G, because Signal Check is showing 800 for both CDMA and LTE.
    • I second the LG V30+. I've had mine for over a year now, and I'm very pleased with the RF performance. I too live in a somewhat rural area, and also travel quite a bit, and I haven't been disappointed at all. RF performance is high on my list of must-haves when shopping for a new phone. The V30+ also makes use of all the current network technologies offered by Sprint, as far as I know. I haven't been able to test out VoLTE yet (not live in my home area), but it's on the compatibility list. I haven't been shopping, but I have seen the V30+ offered at very good prices recently.
    • Yeah it is. East of Sacramento

    • Is this in Cali? The T-Mo roaming is great news, but it would be nice to confirm that USCC roaming is still working on the Pixel devices.
