Yep, pretty simple to do. I haven't merged my complete area yet but I have most of it done already. Pretty slick so far and no issues!

 

Once it goes out public I will probably make one for a few folks in my area.

calling out to bosox.... :D  :D  :D  :D

I received your report, thanks.. are you sure you have seen other GCIs on that version of Android? The error I saw in the log is related to a new HTC security permission that I believe got added with the KitKat update, and isn't in the public version of the app yet (it's in the beta that is in testing now).

I'm not sure. It could have been before the KitKat update. Do you have a rough time-frame on the update currently in beta being released? I saw something about mid-April on your website, is that correct?

I don't want to jinx it.. but let's just say that the way things are looking, you should be counting in hours, not days..

I have discovered that a lot of people are very sensitive about updating their apps for some reason.. it's a delicate balance between the frequency and value of pushing out an update. I love seeing the update button light up for my favorite apps, but others apparently find the 10 seconds they spend downloading/installing something to be the worst part of their week. I'm not out to change human behavior, so I just try to adapt to it. ;)

For anyone complaining about too often updates you can refer them to play store > settings > auto update apps > do not auto update.

 

Alternatively, play store > my apps > pick which ever app to not auto update > menu > uncheck auto update.

99% of all users should auto-update every app they have on their mobile device and on their computer.  The vast majority of users have no idea if an update is good or bad.  They often leave publicly known security exploits on their computer or mobile device by staying on old compromised versions of software.  Then their computer or mobile device becomes a spam machine, DDOS machine, key logger, bot, host for bad software, etc. after some bad person on the internet scans for software with certain known exploits.  Most of these scans are run on computers they have already compromised so that they can build up their bot net anonymously.

 

Only people who really know what they are doing and can tell good updates from bad should worry about manual updates.

I don't disagree at all. But that was not the point of my post.

Oh I am aware of those options, but that is not the source of the problem. The unhappy customers don't usually seem upset about the automatic or manual methods they choose to use.. just the fact that an app is being updated "too often". I think the same folks who get annoyed with frequent updates are those who don't like to see apps with pending updates in their list.

 

Like I said, I'm not going to try (or succeed at) changing anyone's personal preferences or behavior, so I just try to adapt to it.

It's here! It's here! It's finally here! No, not the Android 4.4.3 update due today.. but it's almost as cool: SignalCheck has received it's long-awaited update. Pro version 4.24 has been pushed out to Google Play and should be available shortly.
 
It's been a long 3 months, but it was worth the wait. Greatly improved stability, better Spark recognition, and logging features are the biggest improvements in this version. Here are the major changes:
 
Added location features and options. (Pro)

Enabling the "Location Services" option will cause the device's location to be calculated for display of latitude/longitude on the main screen and/or be included in the log (see below for log details). Users can configure the accuracy/power settings for this feature in the Preferences menu. A location icon will illuminate on the main screen when the service is active, and a quick-toggle is available in a new dropdown menu. Activating this will increase battery usage (the extent of which will vary by device and location settings), so users may want to leave this off when not needed. 

 

Added logging features and options for 1X, GSM, and LTE sites. (Pro)

Enabling the optional "Site Logger" will create a SQLite database that will save an entry for each site that is connected to. If location services are enabled, each entry will include the coordinates of the device at the time of the entry. Each site has one entry; re-connecting to a site already in the database will update the information. An icon will illuminate on the main screen when the service is active, and a quick-toggle is available in a new dropdown menu. More details about the database structure and some more ideas of what can be done with it will be coming soon. Activating this will increase battery usage (the extent of which will vary by device and frequency of log entries), so users may want to leave this off when not needed.

 

Added ability for users to add notes to LTE (if GCI is identified), 1X, and GSM sites. (Pro)
Clicking on the display area of an active 1X or GSM connection will open a prompt that will allow users to enter a "site note" that will display on-screen whenever connected to that site, identified by SID+NID+BID for 1X connections, and PLMN+LAC+CID for GSM. To advertise this feature to users, a placeholder will show if there is no note entered for a site; this can be disabled in Preferences. The site notes are stored in the site log mentioned above.
Notes can also be added to LTE sites, but it is slightly more complicated. LTE sites are identified by PLMN+GCI; therefore, if your device does not show a GCI within SignalCheck, you will not be able to save LTE site notes. Also, for now, the last two characters of the GCI (I refer to them as the "sector bits") are ignored -- this allows users to enter one note that will display for a particular site, regardless of what sector it is connected to. In the future, I may add an option to allow separate notes for each sector, depending on user demand and feasibility.
 
Added ability for the widget to launch system shortcuts directly. (Pro)
Clicking on the widget can now trigger a variety of actions, set by the user in Preferences.
 
Added display of Wi-Fi channel, frequency, bandwidth, protocol suffix, and IP address.

This is the first step in an effort to improve the Wi-Fi features within the app. Wi-Fi information is currently only updated when an update is received for a cellular connection. Future updates will include an option to actively monitor the Wi-Fi connection independent of the cellular connection(s).

 
Added option to disable background service when app is not in the foreground. (Pro)

Due to a bug in Android 4.2+, the notification icon must remain in the status bar in order for the app's background service to remain running in the background. Users can now choose to disable this service when the app is not actively on the screen, which will also disable the widget and logging features.

 

Added new “Site Hint” options for major CDMA service providers. (Pro)

Thanks to input from various users, new "site hint" options are now available. Sprint users will now see two options, as there are apparently different options in different markets. I do not know which markets use which option, so choose whichever seems to properly identify CDMA 1X sectors in your area. Verizon users connected to LTE will see the BID that is colocated at the LTE site you are connected to.

 

Added options to display timestamp and/or device location coordinates. (Pro)

This is a step towards making screenshots more useful. Display of either item is optional, and if the app's location services are disabled or unavailable, the location display will automatically be hidden.

 

Improved display of LTE channel/frequency information available on some HTC devices.

The uplink and downlink channels will be displayed if available, and the frequency will be shown if it can be calculated. A different formula is needed to calculate the frequency for each LTE band, and with limited ability to identify LTE bands, this becomes complicated. Band 25, 26, and 41 frequencies should display properly; other bands will be added as they can be identified.

 

There are numerous additional changes that are mostly self-explanatory:

  • Added BID and street address back to BSL markers in Google Maps. (Pro)
  • Added BSL display to notification icon pulldown. (Pro)
  • Added field to display when telephone calls are in progress, limited or unavailable.
  • Added option for the Reset feature to use the Jelly Bean Airplane Mode Helper Xposed module if a user prefers, instead of the method built into the app. (Pro)
  • Added option to disable expanded notification pulldown. (Pro)
  • Added system shortcut to update PRL on Nexus 5 devices. (Pro)
  • Changed label of “1xRTT 800″ to “1X 800″.
  • Changed label of Reset feature to Reset Mobile Connection. (Pro)
  • Improved recognition of Boost and Virgin Mobile LTE connections.
  • Improved recognition of Sprint “Spark” LTE connections on bands 26 (“Sprint B26″) and 41 (“Sprint B41″).
  • Improved speed and reliability of Reset feature for Android 4.2+ devices. (Pro)
  • Reset feature will now take a device out of Airplane Mode. (Pro)
  • Resolved force closes on GSM devices when the MNC-MNC was invalid.
  • Resolved force closes on some devices when connecting to LTE.
  • Resolved force closes when using the Reset feature. (Pro)
  • Resolved freezing/crashing issues on some devices when connection is lost/weak.
  • Resolved issue with 1X provider name showing as “SID: xxxx”.
  • Resolved issue with alerts failing to trigger. (Pro)
  • Resolved issue with BSL continuing to display after 1X connection is lost. (Pro)
  • Resolved issue with duplicate or unneeded 1X status bar icon on the screen on KitKat devices. (Pro)
  • Resolved issue with incorrect LTE MCC-MNC display on some Sprint devices.
  • Resolved issue with invalid LTE TAC values appearing.
  • Resolved issue with no information showing when in EV-DO only mode.
  • Some system shortcuts will now be hidden on unsupported devices. (Pro)
  • Updated GSM provider database.
Feel free to holler with any questions.. but please don't quote this entire post. A huge thank you to my beta crew for helping me out with feedback and testing over the past 3 months! As usual, the appropriate updates to the Lite version will be pushed out within the next week or so. Enjoy..

Mike,

 

Thank you VERY much for the MUCH needed update!! You've added features I didn't even know I wanted or had thought of yet that are AWESOME (like BID address in dropdown)!! Knowing my WiFi channel and IP are such useful features as well!!

 

Seriously, thanks!

Thank u. So Samsung devices aren't able to get LTE band information or save notes?

Most pre-KitKat Samsung devices do not show the GCI.. so there is no way for the app to know which site you are connected to. I've tried communicating with Samsung, but I don't think my feedback went as far as I would have liked. The latest stock software for the Galaxy S4, S4T, and S5 does show this information (at least on Sprint), so if you have one of these, you should be fine.

 

Well lets cross our fingers that the long awaited nexus 5 update doesnt mess anything up!

My thoughts exactly. When I saw the 4.4.3 posts this morning, I hesitated a bit.. but if an update to SignalCheck is needed, it should be quick, since I have a N5 and Spark is popping up all around me.

That also prevents the app from knowing if you are on band 26, but you should still see band 41 indicated. I've tried communicating with Samsung, but I don't think my feedback went as far as I would have liked.

Looks like the S5 shows GCI IDs now. So, a little progress!

Very good info, I don't think I was aware of the S4T displaying GCI (does the enginerring screen even show it?), and I had not sought out any S5 information yet -- excellent, thank you both! I will edit my previous posts. Hopefully this will no longer be an issue on future devices. Too bad it took so long to get this far.. I know there are a lot of S3 and S4 users who would love to see GCIs.

Really liking the new notes ability. The bad news is. SCP is showing band 26 on a few sites when the engineering screen shows band 25. I've only hit two sites where it did this out of the ten I've gone by today uploadfromtaptalk1397570635061.jpguploadfromtaptalk1397570661238.jpg

Hrmmmmm.. if those channel numbers are correct, you are right, that is band 25. The problem is, the last two characters of the GCI (09) do not follow the band 25 pattern; until now, that had been indicative of band 26.

 

This is disappointing.. or a misconfigured site. Or the channel numbers are wrong. Several possibilities, but I tend to trust HTC's engineering screens unless someone is aware of issues with the M8's screens? I can definitively tell you that SignalCheck is assuming that is band 26 because the GCI ends in 09, which in turn is why the (incorrect) 760/805 MHz readings are being displayed -- the B26 formula is being applied to an apparent B25 site.

      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.
