question about cell connection - AT&T, Rogers HTC One X, Telstra One XL

ok so just a question, because i think i understand what's happening
my phone will switch between umts, hspa and hspa+ a lot
it seems like whenever the phone is idle it sits on hspa. but when i do something requiring data(open up facebook, for example) it will switch to umts and then switch to hspa+
is that just because when switching from hspa to hspa+ it falls back onto umts before switching over to hspa+(which youre probably always on underneath the hspa(+) connection)?

[Q] CDMA Data

I just switched to VZW, and I'm somewhat confused: should I be able to get data over CDMA? EvDO is 3G, are my options 3G, 4G, or bust? GSM has GPRS, which will faithfully deliver me data nearly wherever I am.
I don't know whether my VZW phone is simply mis-configured, or whether EV-DO is required for data access.
evdo rev a is verizon and sprints 3g
Is there anything slower than evdo on Verizon?
FFS one of you has got to bleeding know.
in some rare areas there might be evdo rev 0 witch is a tad bit slower.
1x which is national acesss and will be slower than dial up...
i almost never saw a "1x" / 1xEV-DO / cdma2000 icon on my phone during this trip. when i very rarely did see some icon on screen, it was usually 3G.
would you expect this on a somewhat-off-the-path road trip? i often had 5 bars, but still no data service; that seemed extremely odd to me coming from AT&T.
cdma has a 1x, it's like a gprs in gms
thanks for the help all. seems clear enough now.
now if only 1X had the availability/saturation of gprs, which seemed available basically everywhere.

set UMTS only on an Huawei dongle E160 E173

not sure if this is the right place to ask this question but i ask any way (no harm in asking)
i have an Orange E160 and an Orange E173 (both locked to Orange UK) there are 2 UMTS (i call that 3g from now) i can see one of 3g towers from my house and 1 tower that is HSDPA (i call that H from now) that is less then 15% signal (must be far away) and that is giving me connectivity issues due to the stupid dongle (and mobiles as well) radio is preferring the H tower over 3g even thought 3g tower has 80%+ signal level
i really wish mobile device makers would allow users to disable H/H+ as it makes loads of issues (an H tower always has 3g fall back and normally GPRS as well unless its 3uk network as it has no 2g network) as well as HSDPA uses 30-40% more bat then UMTS or GPRS (to me thats fact as every 3g enabled device with H+ i have had i be lucky if you get an day out of the phone and the phone warms up as well, on gprs/UMTS 2 days normally phone norm stays cool)
the link below looks like the commands to set the speed to basic 3g but not sure how to apply the commands to the device
http://www.shapeshifter.se/2008/04/30/list-of-at-commands/
its the UTRAN command it looks like i want to use to make basic 3g working
or is there custom Huawei software that gives all options
just wish UK providers would Upgrade the towers all to HSDPA or make the Radio based off signal level not network type (UMTS, H or H+) as its cheaper to do (H is not reliable below 10% signal levels)

[Q] Why do phones fall back to 3G?

If i understand LTE and radio stuff, 700Mhz is the lowest band used by verizon for its LTE service. 1x CDMA and EV-DO use higher bands. LTE should therefore have the best penetration into buildings and such. And if you have a 4G phone, it naturally attempts to prefer 4G LTE when possible.
So why is it that my phone is on 3G most of the time? Why would a 3G signal be easier for my phone to hang onto than 4G, when the band used for 4G travels better? Shouldnt it be falling up instead? Furthermore, why is it that when things are REALLY bad it can hang onto a "2G" signal (showing a 1X icon) since that uses even less penetrating frequencies?
The only thing I can think about is tower density and somehow verizon allocating more of its available spectrum to serve older networks. If thats the case then does anyone know if they will ever get with it and shutdown the older networks so that those of us with modern phones can stay on 4G all the time?
Yes I know LTE drains battery, but searching for signals and switching up and down is even worse!

Essentially, the frequency penetration is different no matter where you go based on a whole host of factors ranging from, building type (Materials used to construct the building), weather, interference from other radio devices and electronic equipment. Simply put a multitude of factors (A lot of which are beyond your control unfortunately) lead to some spots having great 4G LTE coverage and a spot that's a foot away having "2G" (1x). These articles might be of interest to you and answer some of your questions: Radio frequency, Frequency bandwidth, and Bandwidth efficiency. Hope this helps .

Only connecting to HSPAP when LTE is available?

I was at Disneyland today and I noticed that most of the time while inside the park it would only connect to HSPAP, and with the amount of people there, the speeds are usually abysmal, however if I go into the secret menu and choose "LTE only", it will connect to it and the speed and signal are perfectly fine.
After I connect to LTE via enabling LTE only, if I switch it back to LTE/GSM auto, it will stay on LTE for a while before dropping back down to HSPAP and not connecting to LTE unless I move out of the area or force it to connect.
This had never happened with my Nexus 4 when I enabled LTE on it. I've noticed that the Nexus 5 tends to switch to HSPAP more often than the Nexus 4 did (granted the radio was not intended for LTE on the nexus 4)
Does this have to do with the phone or my carrier (T-Mobile)?

S6 with network extender

Hey guys
SO I have a weird issue.
In my office, with my wifi connected, I get decent 3g, but if I leave the phone on the desk, I see the phone bouncing back n forth from 1x to 3g. doesnt stay locked in.
When on 3g, I get about -102db, which is sufficient for voice and sms. When on 1x, I get about -98db. Not sure what is causing the constant bouncing....but needless to say, it drains the battery.
EVen while on wifi, i see the radio still bounces from 1x to 3g and back. If I were to get a network extender, do you know if the phone will still look for a a 1x or 3g tower?
I tried the network extender somewhere else, but they had decent 3g coverage anyway. SO I dunno if it still looked for it.
Thanks in advance!
I have the same problems but with LTE
My LTE signal is low so it kills the battery standby. Is there a way to force 3g? All the old apps dont work with lollipop.
