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


Recommended Posts

Since the 800mhz antenna are housed with the 1900mhz how are they adjusted? Can this be done without climbing the tower (remotely) from the site or in a office somewhere?

Each frequency has its own element in the antenna and each element has independent remote downtilt control. In some cases a tower climb may be necessary for larger adjustment.

Is this 1x800 for the past day all I can connect to is 1x

Yes, all 1x800 has a System ID of 5 digits starting with a 2.

Any ideas why I'm not seeing a 1x800 signal worse than -104 in my market? It's as if that's the cutoff level. I have usable LTE down to -115 to -120 all the time....

LTE is measured in RSRP. 1x is measured in RSSI. This is horrible oversimplification (AJ please don't kill me :P) but -120 RSRP is roughly the same as -105 RSSI.

From my experience 1x will not work at -107 or less. So that is about the cut off level.

I'm at a huge music festival currently and I've noticed that my phone sits on the useless B25 carrier when I know B26 is available. I basically have to death grip my phone for it to switch, and then a few minutes later of a perfectly usable connection, I get shunted back to B25, even with B26 on 1st priority. Is it possible that network management isn't fully integrated here yet? And yes, I'm back in EricssonLand...

I think that is precisely your problem. Well, that and b26 ecsfb issues. I experienced the same thing here in Atlanta - obviously an Ericsson market - until they resolved the issues. The phone works beautifully now. Don't worry..they'll work it out fairly soon.

The other day I looked at me debug screen and saw an SID 33792 I didn't know if that it's Sprint or not.

Possibly a glitch or mistake. According to the ifast.org National SID list, that is assigned to a non-transmissable BID. Not sure how up to date that site is but AJ cited it in an article before.

Your in ntelos territory there network is not the best they just signed an agreement with sprint. No timetable on there network build out or when sprint can start using their LTE. Sprint can not build towers there they have to wait on ntelos.

That's either a glitch (maybe you were no longer connected to 1X and the debug screen was having a seizure) or a misconfigured site. Sprint PCS uses IDs scattered between 4103-6225 (mostly in the 4000's) and Sprint SMR is in the 22400's.

So I went and looked at the tower in Athens, MI  and it only looks like there is only 1 RRU per antenna, unless I can't see the second one. Does this mean this site won't be getting 800MHz LTE? The tower climbers said they were installing 2.5GHz equipment, but I don't seem to see those up there either. I wasn't able to get the best pictures since I was taking photos with my phone.

Well the tower must be a good distance away then, I usually have 1 bar of B26. I rarely get B25 at my house or work but I get B26 plenty. I've been seeing more and more lately.

If you see only 1 RRU then it is a Band 25 site only.  I'm not sure where Athens is at, but you could be within the 100 mile boundry of Canada and IBEZ or on an MSC boundry.  I know of a site in Portland and Muliken that are on the Lansing/Grand Rapids MSC boundry, they are Band 25 only.  That is the only odd thing about them.

Okay I have a one max and I've had a problem lately where my phone after it drops b26 it will cling to a dead evdo connection with sometimes -118 dBm will be completely unusable for anything when there is a -90 dBm 1x 800 connection that would at least allow slow web browsing... And this only really happens when I drop off b26 that has been optimized I would guess because lte works farther out the evdo... Just an observation seeing if anyone else has this problem. One thing I must say is that b26 is awesome.

I know that site doesn't fall within the IBEZ boundary. What's the MSC boundary?

MSC is the switch that the traffic routes through.  Click on a site in the sponsor maps and it will list the MSC

    • Today I was driving over in Bothell/Kenmore area. I noticed the site which used to host Sprint eNB 745953 (where Waynita Way NE turns into 100th Ave NE) before it was fully decommissioned last year is now hosting all new T-Mobile gear. The gear isn't live yet but is fully installed. My guess is they plan to decommission the T-Mobile B2/B66 (enB 84647) only site a few blocks up the hill. This is a great move because decommissioning that old site would reduce interference with eNB 84740/175124. At the same time, the new location should notably improve coverage in the geographically shielded area along Waynita/100th.  The weird thing is I can't find a permit for this anywhere!

    • I've now seen 100 MHz n77 from SoftBank and 100 MHz n78 from NTT. NTT seems to be a bit better south of Osaka, though in some cases it drops down to B19 LTE as some areas around here are pretty rural. SoftBank has n77 around, but it's flakey enough that I switched eSIMs earlier this morning.
    • I'm currently typing this from a bullet train headed from Tokyo to Osaka. Using a roaming eSIM rather than T-Mobile as it's a lot cheaper, but I'll start with T-Mobile's roaming experience. Since I have a business line, I can't add data packs online, so I'm just using the 256 kbps baseline service you get by default. That service runs on Softank 4G. SoftBank has a well-built-out LTE network though, with plenty of B41, falling back to B1/3/8 as needed. 5G roaming from T-Mobile doesn't appear to exist though. I've seen 20+10 MHz B41 when I've looked, generally speaking. WiFi calling works well, and voice calls over LTE work fine too (I forgot to turn WiFi back on after doing some testing, so I expect my bill to be a dollar more next month). I want to say I even got HD voice over the cell network for the VoLTE call I did. I have a bunch of eSIMs and a couple of physical SIMs to try out. I've gotten the eSIMs up and running, but last I checked the physical SIM wasn't working even after activation so I'll run through eSIMs for the moment and update this thread with pSIM info and details on not-Tokyo in the coming days. First off, there's US Mobile's complimentary East Asia eSIM (5GB) that I grabbed before my unlimited plan Stateside expired. That SIM uses SIM Club, routing through Singapore, running on SoftBank LTE and 5G. I've seen 40 MHz n77, as well as 10x10 n28, and have seen download speeds in excess of 200 Mbps with uploads of more than 50 Mbps, though typical speeds are slower. Routing is via Equinix/Packet.net. 5G coverage is rather spotty, but LTE is plenty fast enough; either my phone doesn't want to use the 5G band combos that have more coverage or 5G coverage is just spottier here than in the US (at least on T-Mibile). Latency is as low as 95ms to sites in Singapore (usually closer to 120ms), which is pretty great considering the 3300 mi between Tokyo and Singapore. Next there's Ubigi. It also routes through Singapore via Transatel (despite being owned by NTT), and sites on top of NTT docomo's network. I didn't see NTT 5G in Tokyo when I tested it, but since then I've seen 10x10 n28, and have seen B1/B3/B19 on the LTE side. So far it's not the fastest thing out there, but I'm guessing coverage will be a little better...or maybe not. This was $17 for 10GB. Latency is a bit higher to Singapore, but still under 150ms it seems. Then there's Airalo, which was the cheapest when I bought it at $9 for 10GB. It also routes through Singapore (on Singtel), but on my S24 I have my pick of KDDI (au) or SoftBank. KDDI has extensive B41 coverage and I've seen 20+20 with UL CA. While waiting for the train at HND Terminal 3 (Keikyu line) I hit 250+ Mbps down and 10+ Mbps up...over LTE...with pretty respectable latency numbers (not much above 100ms). This is in adition to supporting SoftBank, also on LTE (my S24 defaulted to KDDI, while my wife's Pixel 8 defaulted to SoftBank and didn't seem to want to connect to KDDI). Of the various carriers mentioned, I'd say this was the best pick, though prices have bumped back up to $18 for the 10GB plan...but it's probably still what I'd pick if I had to pick just one carrier. Then there's Saily, which uses Truphone out of Hong Kong. I haven't used this as much, as I only grabbed 3GB for $7. It runs on NTT but doesn't seem to have 5G access and doesn't seem to have as good speeds. Yes, Hong Kong is way closer to Japan, but latency didn't seem to be any better, at ~150ms. In all cases, I've had reception even in train tunnels and even at high speed on the bullet train, on all three carriers I've tried (I don't think I'll be able to play with a Rakuten SIM, which is rather disappointing). There have been cases where service has degraded, but it looks like you'd have reasonable cell service no matter which of the big three carriers you picked...and since T-Mobile roams on one of them, that's good enough if you're content to buy day passes.
