hsdpa and gprs - Touch Diamond, MDA Compact IV General

Hello,
Whe i am connected to internet, my touch mostly goes to GPRS, bus i want to connect bij hsdpa. how can i change that? It is switching automatic now...

Data connections...
Switching is automatic. Your device will connect to whatever is available in your location at that time.
I'm quite amazed at how irregular the HSDPA signal is where I live. I can walk down the street a hundred yards and get it. Walk to work half a mile away and it goes off again... until I get inside, then it's back on again! Modern technology - great isn't it?

Tether = HSDPA....Not Tethered = 3G.... Have you seen this before?

I'm in San Diego, CA this weekend for a NPPL event (national pro paint-ball) and sitting here in the hotel tethering my laptop to my Tilt. So between beers (and NO it's not the beers talking now), I had to reset my Tilt so I pull the USB plug and noticed within a few seconds the H icon on the taskbar changes back to the 3G icon, I thought nothing of it.
I soft rest, plug in, noticed 3G, did a few things, still 3G, activesync complete, still 3G, fire up Internet Sharing and press Connect.... BAM! HSDPA icon and H icon within a second or two. So I further the test.... unplug, replug, start internet sharing, stop it, plug in/plug out.....
EVERY SINGLE TIME... H for tethering, 3G when not tethering.
Now of course, this could just be a total fluke, I will have to test again in another environment and see if I can reproduce. Also, I was able to get both 3G and HSDPA when the Tilt was not plugged in or tethering so I'm not saying that the device only gets higher speeds when tethered.
What was so interesting was the timing, if it was a fluke, it was a very cool one!
Has anybody else ever seen this before?
One side note... San Diego is the home of Qualcomm, the manufacturer of the processor powering the TYTN II/Kaiser/Tilt device. I know this has nothing to do with the spookiness of the icon above but now it's the beer talking, so time to sign off.....
When I'm not actually using data, my Tilt shows "3G". When I do anything that requires data use (web page, email, etc) it changes to "H". Sounds about like the same thing you have going on - when you're phone's not using data, it's sitting at the "3G", but when you're tethered, and using data, it's showing that "H" is in use...
This is normal.
On mine, when I don't have a data connection I have the 3G symbol, when I activate a data connection it will access the fastest (HSDPA if available).
I have noticed that if the HSDPA signal is weak (distance = greater packet rejection) on pure battery I only get a 3G connection, then when a cable is plugged in (power or USB) the extra power available while charging, increases the signal strength and I get HSDPA.
Maybe it was the same at the location you were.
That is the way "H" works. The cell you are connected to offers 3g and throttles up to "H" when data is tranferred. If you had accessed the web on your device when untethered, it would have changed to H as it transferred data also.
i know you asked about tethering.
but my tilt will jump in and out of HSDPA and 3G constantly during any data usage, tethered or not. However it is dependent on location, as in San Diego downtown I get H the whole time(that i paid attention to it), and when I was in North County, 20-30 miles north of downtown I get 3G/H in and out even during constant data transfer(streaming audio)

Never really noticed it before, I just sometimes notice the H, I never put it together that it ramped up during data transfer only. thanks for the info...
It swaps to HSDPA for only as long as it needs to download what it's working on... when you tether your phone you're doing lots of data, so H shows up more.
If you have HSDPA enabled, you'll see it using HSDPA when you use standard data connections from the handset -- but keep in mind, HSDPA & 3g are harder to get good connections for then Edge/gprs... I get HSDPA in my living room, but I swap between 3G/GPRS when I browse the same websites from my basement -- due to the weaker signal strength...

H, 3G or E

There used to be a mod that kept the phone on E always (for battery saving purposes) until data was required or being used, then it would switch to H automatically. Does that exist for the Tilt? I had it on my old 8525....
thanks

Perhaps I mis-understand what you mean but here goes... I am not aware of such a mod.
The handset can be operated in GSM (2G) or UMTS (3G). Potentially faster data connection speeds are available (at possibly higher battery drain) when you use the 3G mode (if available to you) - in this case when a 3G connection is available it may be possible to use the HSDPA data connection (automatically demanded by your hanset only when data is required) but that depends upon: whether you have that service available from your providers masts, whether they have enabled for you it and also whether your handset has the HSDPA setting enabled.
On the other hand only GPRS or EDGE (see wiki here) may be available when a 2G/GSM connection is available. EDGE is basically an enhanced version of GPRS but does not match HSDPA speeds.
So you are mixing the EDGE data indication "E" with the HSDPA indication of "H". The only way your handset can go from EDGE to HSDPA (or vice versa) is if your signal received changes to provide HSDPA from EDGE (perhaps as you change location).
Of course you can disable both 3G and seperatly HSDPA - then you are left with either G or E (use the comm manager and/or the various tweakers).
Beware - some ROMS are incorrectly showing the H instead of 3G when no data connection is active and this is a known problem.
Probably too much detail but may help .

He needs a program to switch between those modes automatically instead of manually though the comm manager, when he enables/disables a data connection..

yeah, that is right.
You know what I do. I use Kaiser Tweak or AdvancedConfig to tell it to Disconnect my 3G connection after 3 minutes. Then When a program needs Data it connects to The 3G network, than when It doesn't need it it disconnects after 3 minutes. Phone still works otherwise. And My battery lives for days.

Let's see if I get this..
You want to run the handset in 2G (GSM) mode for normal voice comms but when you want data you want to switch to 3G (UMTS) so that HSDPA can be used?
I personally haven't seen anything that can do that automatically and understand the problem is that to change from one band to another actually requires a cycle off of the actual phone. There are plenty of programs out there that cycle the phone mode - perhaps you should put this requirement to Dani who has developed a Comm Manager Pro program - his software does this cycling of modes but based upon time and place (for instance) rather than the trigger that you want which is when a data connection is required. Try looking at this http://www.commmgrpro.com/ and asking Dani who is always on this site with the Hermes forum here: http://forum.xda-developers.com/showthread.php?t=299070
Good luck .
Gotta be careful forcing the phone to Edge/HSDPA. Particularly if you force it to HSDPA.
I took a 2 hour road trip today and it took me coming back to figure out why my phone wasn't even getting a signal; it was forced to 3G. I set it to Auto in BandSwitch and it had a signal immediately.
Whoops!
speaking of road trips and HSDPA...
i took a trip today with my wife to Washington and had perfect signal the entire time.. until my battery died of course.
but HSDPA all the way..
i live in Jersey and have travelled to the NYC, the UK and Puerto Rico and have yet to get bad reception...with my old blackberry... im damn near posivtive i woulda had lag

i manually control my data connection through comm manager. i always have 3g off too on comm manager. However, my battery sucks ass and it doesn't last longer than 18hrs with normal use. However, my backlight is at full blast because i can't see the screen outdoors if i don't have it set to 100%. Wish i could see the screen outside during the day and i wish the battery life lasted longer.

Have you noticed any kind of lag in your device when using the AdvancedConfig auto disconnect feature? I "feel" that when I have this feature turned on the device lags a bit. So instead I have the long press end key mapped to terminate data connection and I end up having to hit that so many times during the day.
Hello
This is sort of on the same lines. I use the com manager built into the custom rom im using ( L26_Kaiser_Diamond_V9 ) and throttling back from a 3G/HSDPA connection to the Edge signal. Ive noticed a huge difference battery life. Before i would only get about 4-5 hours standby because I had an application running that kept the HSDPA active previously. If you use a messenger service like IM+ I strongly suggest upgrading to a rom like L26 that has the ability built right into its com manager. It more than doubled my battery life with 0 cost to messaging performance. If i have to hop onto the net or tether, its a simple button switch to re-enable 3g

EDGE/GPRS/3G Questions/Issues/Info

This might be a silly question, but does anyone know if the G1 will be able to access the web if you live in an area where 3G is not available yet? I live north of Los Angeles (who has 3G) in Bakersfield and we don't have it yet. I am hoping that I was not an idiot to preorder the phone and then not be able to use all the cool web features.
Thanks in advance,
Jamie
it should still work on the EDGE network
From my understanding it will work with GPRS, Edge, and 3g so you shouldn't have any problems bro by the way I understand the concern.
With a 1150ma battery, GPS, "big" screen etc, 3G will just drain the battery even quicker.
I will not worry about 3G until an extended battery is released- and the fact that 3G will not be in my market for a year of so.

Hey guys i have a htc wing now, and it does not have a gps. It looks like the gps for this phone is one of the main highlights, because it uses it for a lot of applications. Does anyone know what the gps strength will be like? Will it work will in a building, it do i have the be in direct light for like ten minuites to get a signal?
Anyone with a htc device with a gps already, does it work well?
I hear the android is a-gps, so mabye it will have the ability to somewhat work well when in a pocket, or building.....

Time for a lesson on GPS... It uses satellites in the sky, and you need a view of a certain amount of satellites to find your location (4 will find you but not very accurately, the more the better). If you're in a building, and not right next to a window, no GPS will ever find your location, ever. That's like asking if your internet will work if the ethernet cable is unplugged from the back of your computer and you don't have wifi, it goes against the entire idea of how it functions.
Now, as for the quality of the HTC GPS receiver... People have complained about GPS lag, but I maintain my opinion that it's completely software related, my Fuze had none whatsoever. You don't need to be in sunlight, just have enough clear sky that it can get a reading from the satellites. I've taken trips with the Fuze even on very cloudy days and it took a little longer to get a lock (5-10 mins, it locks in like 30 seconds to a minute with clear skies) but once it had my position, it stayed true. All of the upcoming HTC devices use A-GPS, by the way. Diamond, Touch Pro, Xperia, G1...

He's using the battery draining as an excuse, something to keep him from pulling his hair out because he won't have 3G for another year. Anyone who's used a phone for data features on both networks knows EDGE doesn't hold a candle to 3G.
As for the original post, yes, it will give you all of the same data features on EDGE as on 3G.
The big thing with A-GPS is that it's mainly used to increase the startup speed of your GPS. Instead of waiting 10 minutes to download the almanac of the satellites in the sky from the GPS sats, it downloads the data over your data connection, using the basis of which cell site you're connected to for determining your rough location. This way it only takes about 30 seconds to get a fix instead of much longer.
The sensitivity of the GPS on phones has been fairly good as far as i've seen on devices like the Tilt and such, so I don't see why a phone with such a heavy emphasis on location-based apps would have a sub-par GPS setup. Here's hoping things work well.

3g doesnt burn that much battery unless your using it constantly like as a primary internet for your computer. also when you put your phone in sleep mode it isnt runnig in the background

Exactly... But when you're without 3G, I guess you try to justify why it's not as good, and that's what he came up with. It's like everything though, people on here try to justify why the iPhone isn't as good as the Diamond/Touch Pro, truth be told it's better in many aspects but comes short in many as well.
3g data transfer?

I choose D... all of the above
No... it will not work out of the box.
Yes/maybe... it should work someday soon unless HTC/T-Mobile have somehow disabled that ability in hardware.
As soon as I get the phone I will be working on it on the Linux side (not an actual internet sharing app... more of a route/iptables script) and I am sure someone will work on a java solution (although a kernel solution would be faster). There was an application for the iPhone that provided internet sharing but it was banned from apple store and Google has said they won't do that so I think it should be here soon.
problems with Wireless (3g and wifi)
does anybody else have problems with the 3g?

also does anybody have problem conecting to wifi?

I have an issue with my G1 WIFI connection. If i broadcast my SSID I connect with no problems. but if i disable the broadcast it will not connect, and this is with me manually putting in the connections into the phone.
I called TMobile but they said i needed to call HTC. they didn't have a solution.
BTW, I have no WEP enabled. I just disable the SSID broadcast.
I just connected to my Linksys router with WPA2 and had 3G running, connected no problem.
Haitiankid: try entering the details of your network manually and seeing if it will connect then. Also, as for the 3G fading in and out, are you in a week signal area for 3G?
wifi working
I got my wifi to work. It was my routers fault. What I did was in went into my routers settings by typing 192.168.1.1 and entered 'admin' (no quotes) and no password. Once in my settings I changed my brocasting type from b&g mixed to all mixed changed frequency to auto, changed network key from shared to open and wifi started working. I don't know if all those steps were neccesary but it worked for me. Hope it works for some else.
As for the 3g it seems to be getting better
for those of you with the 3g/edge switching problem...
Hey, if uve got the 3g switching to edge back and forth continuously, its likely because you didnt get a new SIM card when u got the g1. It simply means you have an old SIM card that doesnt support 3g well, call tmobile up tell them your situation, theyve given most people a free new SIM card thats more compatible.

I don't think that's the case. I've had the same SIM card since 2000, no problems like this. If any SIM is too old to support 3G, I'd think one made 8 years ago would definitely be the case.
It sounds like he's in a bad coverage area, which could be lots of things. There is a coverage map on the T-Mo website, don't know if it shows 3G. Or it could be the building he's in. My phones have never worked at my grandmother's house. I get full bars on the front porch, and full bars the second I get out the back door, but no signal in the house itself. Even relatives on other networks get little to no coverage inside the house. Probably the really really old insulation and building materials are blocking the signal. At my last apartment I only had a good signal on the corner of my bed, and that disappeared when new neighbors moved in upstairs.
These are radio waves, which aren't foolproof or perfect, they encounter all kinds of interference. Nothings going to be as secure and consistant as a wired connection. Nature of the beast, unfortunately.

Careful dude, with the security set to open anyone within range (neighbors, wardrivers, etc.) can use your wifi to get on the internet. Try using WPA or WPA2 security, but leaving it all mixed and frequency at auto.

[Q][UPDATED] Big issues on ATT's network?

Now, you may know me for having immense troubles with my network connection speed, reaching .06Mbps (60Kbps) down and rendering my phone's wireless internet unusable, regardless of ROM, modem, or any real variables.
After a new SIM card from ATT and a few lucky Master Clears (where it worked after each session for roughly one hour before locking up again), I think I may have found the cause...Or so I thought. IP addresses weren't the culprit.
What is awkward, however, is that my EDGE service now works, and it's faster than my 3G service. On EDGE, my internet is 3 times faster than that of 3G, again still poor, but an improvement nonetheless. Thus, I've concluded that it's an issue with 3G and either my cell network or my phone's 3G cell chip.
How could I go about diagnosing this issue? I want my 3G service back... I have changed modems several times, and switching ROMs doesn't do anything. Anything I can flash, use Service Mode, etc, I'm game for. I don't want to keep throwing money at ATT if I can't use the service.
EDIT: Signature is showing my current internet speeds over HSUPA. HELP!

On ATT's network, one is authenticated with an IP address, as you may know. This is reflected in SpeedTest.net's plank for "External IP" in the results browser.
When I was getting real download speeds (my standard HSUPA rated 5.1Mbps down, 1.7Mbps up), my phone is connected to an IPv4 address beginning with "166.199.xxx.xxx". On UMTS (where I would get anywhere between 1.6-3.4Mbps down, 1.6Mbps up), the phone is also connected to "166.199.xxx.xxx". On 2G with decent speeds, I would get the same results yet again.
However, over the past week or so (since the 16th of January), I have gotten craptastic download speeds of .06Mbps and equally lousy upload speeds of .11Mbps. I just realised that in these cases (which happen after using the phone for roughly 45 minutes after a Master Clear and permanently stay that way), my phone is connected through a "32.16x.xxx.xxx" IP address.
What does this mean? How can I force it to stay on the "166" IP/network? ATT has been of no assistance, whatsoever, so I call for your help, XDA community!
EDIT: Sometimes, I think I'm being too technical in detail because nobody ever responds, but I just don't see this going in the Android Development board.

You are assuming that all of those IP addresses are routable through whatever network you are connected to. Perhaps there are some "crappy" towers connected to a piece of the network that sucks and you happen to hop around onto them?
Either way, why not just set the adapter manually using ifconfig to test your theory?

Hm, this didn't work, speeds didn't change and I found that it's band-dependent; 32.xxx.xxx.xxx is just the 850 band for my area, while 166.xxx.xxx.xxx is the 1900 one. However, using EDGE now works since meddling with it, so I can at least reduce this to a 3G specific issue. Any pointers?

Mobile Signals work upto what Altitude ?

I was just planning to Map my Route through MyTracks App from a Flight
But , the problem is , the GSM Network will not work after few thousand feet ...
I want to know How much Altitude, cuts off the GSM Signal , and what are the alternates to get the Network Data working while still flying..
I know we can Pre-cache the Maps but...I want to do this experiment...Has anybody tried ?
unless you are on a small private plane, your phone should not have any of the transmitting antennae turned on (phone, WiFi or Bluetooth) as you'd possibly cause interference issues with flight equipment. Also it would likely breach current safety regulations, hence you are asked to turn such devices off by the flight crew before take-off.
Certain aircraft/carriers allow GSM calls, but use an on-board GSM cell to handle this, not sure if there is additional roaming cost for using this feature.
http://en.wikipedia.org/wiki/Mobile_phones_on_aircraft
@indiandroid
As far as I know, it is not the altitude that cuts the gsm. Other factors are the high speed, and the amount of towers in range. Even though, the phone could connect, it has to switch towers too often to get a steady connection.
If it works though, I wouldn't worry too much about interception, as there is still no case, were phones lead to any problems.

I was playing with my phone during takeoff to see how far I could go before losing signal. I was looking at the GPS, GSM signal, and even barometer sensor.
GSM signal was lost at around 3000 feet.
At 200 mph during takeoff, Google maps had a hard time 'keeping up' with my location. At 400 mph, the GPS satellites had a hard time getting a lock.
At cruising altitude, the cabin pressure drops to around 700 millibars.
It's nothing to do with altitude, it's range from the nearest mast: http://www.youtube.com/watch?v=jpxb7txWZIc&feature=relmfu
I hope I'm never on a flight with any of you. You'd think you'd be able to manage a flight without your transmitters on...
