Everything 800mhz (1xA, LTE, coverage, timeline, etc)


Recommended Posts

I live in the Nashville market and we have many, I mean many 8T8R site's. I'm rarely not on band 41 outside.

I had band 41 most of the time too. My problem was that in the part of town i was in, it was all clearwire 41. Do u know whos band 41 u were connected too

Ideally this would be discussed in the Nashville thread...

Detroit's in the primary IBEZ (100km or less from Canadian border), and so far nobody has found 800 in this zone, only the secondary boundary is known to have it so far. It's still better than the whole IBEZ+20km that Sprint had imposed for the longest time.

So I have a question that might stir up a little chatter here. 800 is known to obtain usially better distances than the 1+GHz. I'm curious about approximate maximum distances and locations of connections that others have attained made either with LTE or 1x800.

 

My personal best happened a couple days ago in the morning via 1x800. I connected to an 800 site just north of Pittsburgh, PA metro from approximately 30 miles east of Cleveland, OH. I crunched some numbers with the coordinates I had of the site (likely an offset, but probably not an enormous difference) and of my device and it came out to a little over 70 miles away. I was cheating a little. I learned years ago that morning propogation enhancement on VHF/UHF frequencies via tropospheric ducting often occurrs in my area. And it is often times even more enhanced in the spring and fall months. :)

I've actually gotten B41 (from a Clear site no less!) over a further distance than 1x800. I've connected to a site about 10 miles away on 1x800 (physically in Ohio, but the site was in Pennsylvania). On B41 I've connected to and used a site 13.2 miles away.

How even!!!??? B41 doesn't even go a mile here in Seattle!

The site is on top of a large hill, and most of the distance was across open water (SF Bay). There are a couple buildings between the bay and where I was at, but it's close to line of sight. I quit connecting to it once local B41 sites started coming online, but it still shows in my neighboring sites in SCP with a signal of around -115.

It just sucks that San Bernardino County can apparently prevent San Diego from getting B26 even though the IBEZ issues with the Mexican government have been presumably? resolved and the former is fairly far of a drive from the latter. On a recent trip to the Bay Area I almost never dropped down to 3G or 1X (the latter happening in one possibly shielded room in an office building), whereas drops to 3G happen extremely often here in SD.  :( Hopefully the densification effort will help.

Yeah, it doesn't travel that far here either.

 

Different sites, different equipment, different setups, different geography, atmospheric effects, etc... 

 

You can't generalize like that. I am sure there are sites that have wider footprints than that.

Cells are much, much smaller and tighter in dense urban environments.  If a Band 41-equipped tower attempted to cover a cell with a radius of 13 miles, centered on downtown Seattle, it would have a potential poulation to cover of several million people.  That is clearly absurd and, not to mention, absolutely impossible.  So the cells are tuned to cover manageable potential populations, translating into a very small geographic footprint in a highly populated area.

It does suck majorly that SB county has been dragging ass on their reband effort because sprint has been hampered from deploying 800 cdma and LTE all of So Cal and Vegas.

I have seen the long range B41 sites too when you drive along I-15 before and after you pass the tower in Primm, NV. My guess you hold on to the signal for about 8-10 miles in each direction. There is nothing blocking the signal.

So I have experienced B26 for the first time in my life as of like 2 days ago because I am staying at my aunts house in Houston for a thanksgiving family reunion :). What I've noticed is that B26 dies when EVDO is still at -98 or so dBm (my aunts house I either get -114 to -118 B26 or EVDO). Is this B26's full potential ot is it just not optimized? I've seen videos of B26 eclipsing the range of EVDO by a lot (

) but my experience just hasn't patched up...Shats going on here?

In my experience that's about where it drops off and goes to 3G.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however.

    • Still nothing for my AT&T and Visible phones.
