  1. Band 26 -110 signal for me has less speed than, band 25 -110. I believe it is like that because more people are being moved TO band 26. But band 26 does perform decent here, At home I just got a -111 signal (with the Booster) from a site 14 miles away, as the crow flies.

    LTE on 800 may have less bandwidth because in many cases the channel is narrower, too.


  2. The cable company i work for uses 8 downstreams now.  By the end of the year it will be 16 so something is in the works.  Just make sure houses are clean NOISE (ingress) is a killer on speeds on CATV systems.  Most people believe the old foam master antenna wiring in there houses doesn't need to replaced.   :wall: .  Its not really is dual shield coax and most of it isn't 75 ohms.  

     

    Not 75 ohm?  Impedance mismatches cause visible artifact in analog television, so I doubt that.

     

    Ingress on cable is also very hard to track down sometimes, as are ground loops.


  3. Well, when I am driving on high way, why they keep putting me on B41

     

    What sort of device?  The Photon Q that you have listed on your profile is not capable of operation on LTE other than on Band 25 (1900 MHz PCS).  It isn't known for the best reception on 25 either.

     

    Now, assuming you have replaced your device with a more modern telephone, it should always want to put you on 41 if your device is capable, as the capacity is the highest.  Once you get to the edge of range of 2500 (or the carrier becomes oversubscribed), you would likely be bumped to a band 25 (1900) carrier, which has approximately twice the range at a given transmission power and antenna angle.  After that, and assuming you haven't come into range of a stronger 1900 or 2500 signal, you would be moved to 800.

     

    Remember that the system cannot place you onto a band beyond your device's reception range.  If you are on band 25, it can't just send you to band 41 unless your device communicated its ability to receive it and that its current reception is acceptable.  There is constant back and forth of control data between your device and the cell site, indicating the capabilities of your device, its current signal reception levels, and also instructing your device on which band it should park and operate - again within the bounds of its current reception and channel loading.


  4. Forum Newbie, please be gentle.....

     

    Is there a map that will list Sprint towers in a particular area?  I'd like to know where the towers in my area are, how to check them out, etc.  With Sprint sucking bad in my area, I'm contemplating leaving them.  But, if I can get an idea of where towers are, and find out what sort of upgrades if any have been done, I might find a way to convince myself to stay! (I'd almost hate to go back to Verizon!)

    Thanks guys!

    For what you get, the price of the maps is very cheap.  It's really cool to be able to watch progress happen almost live.

     

    Also, it's an interesting study in network design, at least if you know the areas and their population densities.

  5. So anyway, all, I took apart my phone and cleaned everything nicely, adjusted the tension on the contacts, put an anticorrosive contact protectant.  It seems to have helped, but I will know more when I am out and about tomorrow.

     

    The lack of 800 is going to be annoying because I am going a few places out of town next week where I am told the 800MHz service has made a big difference.

     

    Going to see if I can figure out a root-less method of loading PRL.

  6. To revisit this thread, the Galaxy Note II is getting long in the tooth. The time may have come to confine it to the "cellphone coffin" -- aka the old handset/tablet drawer.

    Moo again?

     

    My wife took my Note 2 after her Photon Q was run over and I got the S4T. She has no LTE related issues, guessing you've got some bunk hardware.

    Yes, mine has exhibited this change quite suddenly, as in it was working one day and the next it was not.

     

    To blame this on an aging hardware platform is an excercise in questionable logic at best and a display of outright idiocy at worst. I seriously believe that something has suddenly (or cumulatively but with a sudden manifestation) changed with this device, whether in hardware or software. My firmware was recently updated, but that was at least a month before this issue began.


  7. That's very strange and unfortunate the note 2 I had for a few weeks had superior LTE signal strength to any of my others phones... It very well could be antenna contacts.

     

    About my s3 those Dbm I said were from the same tower in the same spot at my house. I meant to include that it was great signal then went bad. I watched it with signal check pro. I noticed its new behavior after I mapped a long sensorly trip plugged in. I guess it got to hot. Anyway just the 1x pcs was affected that's why I jumped on this thread sounded similar to my problem. However 1X 800 still works great..

    The Note II does seem to have somewhat better LTE reception normally than my S3 did.  The S3, however, was still better than most other phones even a year or more after its release.  I find that the S3 was a lot better behaved with the CDMA side of things than the Note II, routinely showing better numbers for data speed on EVDO on the same channel of the same site.  1x reception is about the same.

     

    As for 800, that is irrelevant for me at this time.

  8. My galaxy s3 has a similar issue. The 1X 1900 radio is 20 dB out so higher than ehdpd and usually higher than LTE.

    Ex 105 for 1x and ehdpd will be around 80.

     

    I took my s3 apart and there are burn marks on the motherboard and it smells like a blown capacitor does. So my problem is a hardware failure. Maybe it could be something similar to that.

    Does it get really hot when using LTE or 3g for long periods of time?

    This can be normal.  Your S3 can actually connect to 1x and EVDO on different sites.  It's not common, but can happen.  Remember also that the two services, even when running on the same site, work on different frequencies.  They might be 20 MHz or more off from each other, depending on what Sprint is licensed for in any given market.  There's a lot of room there for interference that could affect one but not the other.  LTE RSSI generally isn't accessible, so the meter you have, RSRP, is actually based on the average of the amplitudes of specific components within the signal rather than raw signal level.

     

    In this case, I have a very good memory for signal levels in specific locations or areas.  Mine have dropped hugely on LTE, to the point that my phone is on 3G about 80% of the time when I am near home.  It used to be more like 30% of the time on 3G.

     

    I had a phone a while back with reception trouble.  It was caused by some deposition on the board at the antenna contact points. I cleaned both parts with contact cleaner and the problem disappeared. Almost looked like electro-galvanic reaction.

     

    Your S3 has solid capacitors, which do not smell when they fail.  There are other components in there that might, however.

     

    And no, it does not get hot.

    Moo?


  9. I have never had reception complaints about my Galaxy Note II until recently.  It seems to have decided to live primarily in 3G-Land and not pick up LTE unless you're practically within sight of the tower.  I just grabbed it off of my table a few minutes ago and it showed LTE @ -117.  In this part of my house, it should be -103-106.

     

    Overall, reception seems between 10-20dBm below what I am used to seeing in any given location.  Any ideas about this?  My Galaxy Tab 3 is not affected by this problem, and my Note II is frequently on 3G when my friend's Note II is on LTE with decent signal strength.  Are there any connections in this phone that might require cleaning (as I have seen in other models) or is it simply malfunctioning?

     

    CDMA reception does not seem affected at all.


  10. ...

     

    Worth mentioning that the roaming data is very bad. Even if you connect to HSPA+, the speeds and latency are artificially throttled to below-EDGE performance, so your not getting any better connection over HSPA than EDGE.

     

    Sounds like Verizon EVDO roaming for me.  I HOPED to get on even just 1x with Sprint because Verizon's EVDO roaming was so bad.  Their 1x was really bad too, maybe 25 kbps tops.


  11. Just because someone isn't aware Nextel isn't an active network doesn't make them stupid. Anymore than you being unaware state statute 17-240 was replaced with 18-240A, or something of the sort.

     

    Don't be arrogant.

    I am not being arrogant.  Facts should be vetted before a press release is made.  It's that simple.

  12. Honestly I highly doubt it, If they are on a tower by themselves its a county tower with at least one county antenna or on a water tower, (at least around here).  The big two have more money to have there own towers, or at least that is my understanding whenI have talked to a guy I know really well at Sprint (on the tower technician side). Its not to say you will never find one registered with Sprint, but good luck.... However I have come across a "Sprint/Nextel" one back when they first merged BUT Nextel was First on the tower.  

    Primarily a few Nextel sites in remote areas, on which Sprint and Nextel were the only carriers.  As I said, I know they sold off whatever they did own that others would buy a number of years ago.


  13. 90% of the Protection Sites I've seen are Huawei gear. The ones in Lamesa Texas, Flagstaff Arizona and North Bend Oregon are the ones I recall off the top of my head that were different. At least of the ones I've seen. I have seen a couple others too. The other 50 or so Protection Sites I've seen are Huawei. All the ones in NM are Huawei.Robert via Samsung Note 8.0 using Tapatalk Pro

    I need to get you some Michigan pictures. Some are pretty odd.

  14. Hey I was wondering why Sprint will keep using microwave backhaul on clear sites and go to fiber on Sprint sites? I'm assuming it's a cost thing and why Fix something that isn't broke right? I'm assuming the microwave way is still very efficient back haul?. Thanks.

    It can be. It works fine as long as the link has sufficient capacity. You can easily do 1Gbps full duplex at the distances required for 2500MHz site spacing.

     

    The issue comes in with how many hops are required between points where the network is loaded. Ex. 3 sectors TD-LTE will require about 450 Mbps in a perfect world, about 250 in a more real world. This means that with a 1.5 Gbps connection, four or five microwave hops would be a practical maximum.
