[Q] 3g weak in buildings!!! - Nexus S Q&A, Help & Troubleshooting

Hi guys, my 3g (Tmobile) at home is excellent, but whenever I'm in school buildings, internet rarely works even though there are 3 or 4 bars does anyone know a solution for this??!!
Thank You

I have this same problem except my connection is bad at home and good everywhere else

My whole connection sinks when I'm in school buildings, most of the time no connection at all (emergency calls only). I see people on 20$ boost mobile phones still being able to atleast text.

The 3g issues arise from the frequency at which days data is transferred. Because it is high its building penetration it is less than other similar technologies

yup we need both 1700+2100 to make a proper 3G connection
while AT&T, Rogers, etc. they only need 850 or 1900, but they do not need both
i had to sacrify my 850 for the AWS, due the amazing price package

said before, tmobile's 3g network uses high frequencies which have bad building penetration, 1700/2100mHz. the lower the frequency the better the penetration of structures, like 850mhz is much better at going into buildings, reaching far distances, and better propogation properties.
nothing can be done about it, its a law of physics limitation. the only solution is to double the amount of towers/distance between towers in half.

[Q] Question about bands/3.5G

1) How can I tell if my phone is running on a 3.5G network? I am on T-Mobile in Virginia Beach, VA.
2) I know there are different bands out there for different carriers, so can I change to a band that can get me better 3G coverage? I have slooooow 3G coverage where I am right now.
Any help in the right direction would be awesome, and don't be afraid to dumb it down for me. I am getting pretty savvy on all this phone stuff, but bands still elude me.
Hi
until recently, 3.5G was known as HSPA7.2. If your device shows "H", then your device can use the HSPA (real) speeds.
If so, and your browsing is slow, then this is mainly due to saturation and low signal strength, but exists more factors.
To use another bands, you must change the service provider (and change your device). No manually way to do it.
Best regards

I recently visited Jacksonville Florida where my CM7 Rom showed me I was running on 4g. When I came back home to Virginia Beach it is showing me a H. Stock rom shows me as 4g but CM7 still shows me as H (HSPA). Is this truly telling me that I am operating on 3.5G network here in Virginia Beach?

SGS supports HSPA+ ?

Hello ,
I have a Samsung Galaxy S . My carrier never had a 3G network .. so ive never really felt what its like to use a smartphone to its full potential .
And just a week ago they introduced HSPA+ . Now i have a couple of questions , since this wireless technology is evolving too fast for me to catch up with :
- HSPA+ is 4g ? 3.5g ?
- Does my phone support it ? to my understandings , i can connect to it but not at full speeds (21Mbps)
- Is that good news for me ? i mean they skipped 3g and launched HSPA+ ? should i be happy with that ?
Excuse my noobness ,
Cheers !
Your speeds will depend on your network and possibly your data plan.
Different carriers use different "bands" for high-speed data and the SGS may or may not support your carrier's band. T-Mobile, for example, uses the "AWS" band, which is not the same that, for example, AT&T uses.
If your data plan doesn't allow access to the APN that supports HDPSA+ then you won't have access to those speeds, even if your phone has a compatible radio.
There is a lot of specs-manship and marketing hype about what is and what isn't 4G.
On my SGS4G I am seeing over 4 Mbps down and over 1.5 Mbps up with T-Mobile in the San Francisco Bay area. I've only tested one location (that has mediocre signal levels), so it may be better elsewhere.

G2x 3G????

I have noticed in the 3 days since I have had my g2x that I never get 3g, I either get 2g or 4g on my status bar, but never 3g. Anybody else having this issue?? Considering sending it back to TMO for a new one. And yes I have a new similar card, got it about 3 months ago when I had my G2.

I've noticed the same thing though idk if that's really a bad thing....
They probably lumped 3g and 4g together.
That's what I was thinking but wasn't sure.....has anyone seen 3G on their status bar ever????

I've read other threads here where people report seeing a 3G icon... I haven't seen it myself.
But it's possible that we're in areas where HSPA+ is turned on, which is "4G", and once you leave that range, you are in 2G (EDGE) territory. In other words, there's no area near us that is just HSPA (3G), it's either HSPA+ or EDGE.
Too many people not doing a search. No one has seen the 3g logo/symbol yet. Also a side note for those complaining about 4g speeds:
T-Mobile USA uses the 1700/2100 MHz AWS Band for its 3G network. The carrier states it allows faster download and upload data speeds utilizing HSPA+ technology, which allows for simultaneous voice and data. Upgrades to HSPA+ are planned for 2009 through 2010 which may boost average download speeds from 7.2Mbps to 21Mbps. (Reported from http://en.wikipedia.org/wiki/T-Mobile)
But my old G2 that I had just a few days ago hag Edge(2G), 3G, and H(HSPA/4G). Now with my new g2x it's either 2G, or 4G. No 3G.

yes they are lump together. It's always 4g or 2g. It's a marketing thing, they want us to think that we always have 4g, when a lot of the time we're only getting 3g speeds.

Actually there is a thread here where someone stated they did see 3G (I'm skeptical) on a long distance driving trip they did.
There is also a comment from someone that the "missing" 3G icon is a bug TMO is aware of and will fix in the first software update. Take it for what it's worth (although I would believe this one).
You will not see a 3G icon appear on any TMO 4G device.
Here is the reason:T-Mobile is using the same frequencies for 3G as they do for "4G". Meaning they are using the same cell tower/antenna. The upgrade in speed comes from a base station software upgrade and a strengthened backhaul. HSPA+ devices branded as 4G literally cannot tell the difference between 3G and 4G.

You forgot a technology: UMTS (on which HSPA is based). It can tell the difference between UMTS and HSPA (but not HSPA and HSPA+). That's why other phones have had separate "3G" and "H" icons. Both were originally 3G technologies (in the same way that GPRS and EDGE are both 2G), but HSPA has been expanded to now qualify as a 4G technology (I'm not going to argue semantics here, HSPA+ is 4G and provides faster speeds than WiMAX).
Has anyone pulled apart the framework-res.apk to see if there's a 3G png in there?
I haven't seen 3g sign either, only 2g or 4g, mostly 2g though, and I'm in vegas... I'm returning the phone for that reason, and I have very bad light bleeding from the top corners too. When calling t mobile, they don't even try to troubleshoot, I guess they r aware of that problem already. Now I'm waiting for another one in the mail

Just to add: The G2x is limited to 14.4Mbps theoretical maximum download speed So you won't enjoy anywhere near 21Mbps, or 42Mbps which is now rolling out slowly and is already in 3 cities (Las Vegas, NYC, Orlando). The most I've gotten on my G2x is 7.9Mbps down.

My beef is not the lack of a 3G icon, although I have yet to see one on my phone.
My beef is the lack of reception at my work, a problem the Galaxy S 4G and MyTouch 4G dont seem to have.
And why does the phone say UMTS when its on 4G ?
That right there tends to make me think the phone has an issue
(along with poor/no reception at work).

Force 4g LTE service?

Is there anywway to do this? I am right on the edge of 3g and LTE service and it keeps bouncing back and forth. I dont think you can, but thought I would check with you guys as well.

If your phone doesn't connect to LTE by simply cycling through Airplane mode, don't expect forcing LTE mode to connect either. All Force LTE does is disable every connection except LTE ones.
If you live in fringe LTE coverage, and your phone bounces back and forth, your best bet is to disable LTE for the time being.
Source: The office I work in was in the same situation a couple months ago. All of us with Sprint LTE phones learned the hard way that this is the solution.

You could buy a signal booster? They work really well in doors. Sprints 1900mhz LTE has trouble penetrating buildings but it gets good area and distance coverage. In a few years when they roll out the 800mhz LTE they will get building penetration as well.

I would not recommend buying a signal booster. The reason people are in the edge of an LTE signal is because a tower further away has been upgraded, whereas the closer 3G tower doesn't have upgrades. Hence, you connect to 1x Voice to the closer tower, but LTE on the one further away. I would just wait it out. eventually you will get LTE when your closest tower is upgraded.

I don't think you know what you're talking about. I have seen signal boosters used on log cabins deep in the mountains and gain full bars of 4g LTE service when there is no service whatsoever available outside of the booster zone. They work. Period.

I never said that signal boosters don't work. But the cost of them is not worth it. Paying $350 for a booster, just why? I could see it being worth it in a rural area when Sprint doesn't have many towers and no intention to build more, but in an urban area it is pointless. I was to understand that the OP didn't have 4G service at his workplace, or did but it was pulling in 0 to 1 bars (over -100 dBm). But, at his workplace, he has perfect 3G signal because there is a tower closer that doesn't have 4G service yet. So why buy a booster, spending $350 on something that will fix itself in the coming months.
Point of the story, if you have great 3G signal where you are, DO NOT BUY A BOOSTER. You will get 4G eventually. If you do not have great 3G signal, don't expect to get great 4G signal either. If you don't have great 3G signal in a rural area, the booster will help.
Another thing to note, if you live in an area right between two towers, or at the edge of signal. It may be worth giving a call to Sprint and saying you don't have service in your home. They may send you an Airave. This thing works basically by using your home internet connection to create a router for Sprint phones. The phones will use the "router" for voice and texting, and data as well. It essentially gives you a small tower in your home. The catch on this is that prior to Softbank's purchase of Sprint, Sprint sent these things out to anyone. Calling and complaining to Sprint about poor coverage would yield them sending you an Airave. Now, you must pay $200 for this device of you have between 1 and 3 lines. If, however, you have 4 lines on the Sprint account, you may get it for free.

Heres the thing - Even with good coverage outside, 4G LTE on 1900 mhz spectrum has difficulty penetrating buildings. Doesnt matter the towers. 800 mhz spectrum is only in its infancy and 800 mhz will never be compatible with our current phone model of choice the MPQ with a slide out keyboard.
For less than the price of a new phone you can boost your signal to receive the 1900 mhz LTE indoors. I'm not getting a new phone unless it has a slide out keyboard and it looks like thats not happening any time soon. So for someone who wants LTE on the MPQ indoors, a signal booster is highly economical. Not to mention for consumers that cut the cable and internet bills and use mobile broadband hotspots for all their home entertainment needs. That one booster can save you the $150 month cable/internet bill for perpetuity. It pays for itself in 3 months.
In short- 4G LTE is here but its building penetration is disappointing and to get on the 800mhz band you need to buy new hardware (phone) anyways at an undetermined future date.
Sprint Sucks!!!
Just saying.

[Q] Nexus 5 T-Mobile Signal Booster Not Working

I have a T-Mobile CelFi booster because the way my house is built, which seems to block out signals to various carriers. The booster worked pretty well for Nexus 4 and HTC One. However, now that I have Nexus 5, I am getting consistently low bars of signal. People on other end of calls often tell me they can't hear me. I am not entirely sure if the booster just doesn't work with Nexus 5. Based on my observation, it seems to be trying to hang onto signals from the tower for longer before it switches to the booster, though I cannot say for sure because honestly I am not sure if that's how it works or not. Anyone have similar experience or might have a suggestion on I can fix this?

Theory:
Nexus 4 doesn't provide LTE, only HSPA+. Nexus 5 is LTE. LTE is preferred over HSPA+ when available. Your booster is likely an older unit that only supports HSPA+ and does not improve LTE. Therefore, your Nexus 5 is getting boosted HSPA+ but ignoring it in favor of a weak LTE signal.
Just a theory, though.

This is certainly plausible -- however, it's puzzling as the OP indicated that s/he's having voice call issues. The old boosters only supported AWS, but I know of no T-Mobile area that would have LTE and PCS HSPA, but no AWS HSPA.
I have an old booster, and last I checked, it appeared that my N5 was using it just fine (I have no real coverage issues, but I stuck the repeater in my basement to improve signal there). However, I don't have LTE coverage at my house, so I'm unsure if there are any LTE->HSPA handover vagaries that the booster could be exposing.
There is a newer booster that supports LTE and PCS HSPA. According to a thread of Howard Forums, T-Mobile has them, but getting one appears to be a challenge. You may want to take a run at upgrading the booster by calling CC or retentions.

I got my booster less than a month ago, older version. There are times where I get a faint LTE signal at my house, but the booster usually pushes HSPA+ over the LTE. Maybe the OP needs to position the booster and receiver in different spots? I had to do this as well. To the OP, do you suffer from poor call quality outside of your house in your travels, or just in your house?
