Edge network speeds

I'm not sure if this is the right forum for this question, but i'm sure a mod will move it if its not I live in hill billy hell, so i get gprs/edge networks out here, when i cant jump on an open wireless connection, and i wasn't really paying attention, because everything i was downloading was comeing in around 3-4 Kbs tops. I am useing Ubuntu linux, which i am new too, and i realized one ot the packages i wanted wasn't installed, so i opened synaptic and found the package clicked apply and switched desktops, to play a lil bit of mobsters. So a few mins later i switch back over,and i see synaptic DL'ing at like 15 Kbs. So my questions are these: is 15 Kbs accurate over edge, or was that possibly a mistake, and if it is possible, are there settings i can change on my box that will allow me to connect at faster throughputs.
ubuntu 10. something the new one
connecting useing the opensource wifi tether advertised here, useing the edge network mostly, the gprs seems faster at times, but the signal isn't great.
Any advice or pointers is greatly appreciated

try downloading anycut then create shortcut->activity-> phone info
click it then scroll down and select WCDMA only it might help forcing your G1 to 3G connection I hope it will help

obviously it depends on a few things, i too use ubuntu 8.10 and i usually get arount 20kb/s when tethering on edge. sometimes i get a weird spke and sometimes i get some real bad lows, it really depends on the time of day and a whole lot of other factors.

AT&T 3G Speeds

Can someone who keeps close tabs on their data speeds with AT&T run a speed test and see what you get?
I just read on wmexperts.com that AT&T has completed their 7.2 HSPA upgrade to the 3G network and I am getting some really high results on speed tests, but I don't really know what I would've gotten a week or two ago.
Can anyone confirm that the network is much faster?

i did this speedtest.net with my laptop connected to my fuze via usb. i had 1 bar of reception. i got a download speed of 1.3mb/sec not bad at all

Full bars 120ms 1.3 down, worse than usual.

Okay, I just got 11834 kbps at mobilespeedtest.com. But I was using the skyfire browser, so is that cheating because their server downloads info and then sends it to my phone?

Okay, I tried it with IE Mobile and got 3213, 2000, and 2991 kbps. With 1-2 bars.

im on energy pheonix rom, on long island. in H data mode.
I ran mobilespeedtest.com in opera with 3 other tabs ope (old browsing session) and got 294 Kbps, 400 Kpbs.
Then in IE Mobile: 377.
Then I clicked the "test again" link on the mobilespeedtest for a 1 MB download, in IE mobile, and it returned 2388 Kpbs, 2197 Kbps.
Then ran the 3 MB test, 2050.
So dont just trust the 100KB test, click the 1mb. Then a 3mb. If your speeds increase as you go up, latency is the problem.

Changing MTU from 1428 to 1500 Yielding Speed Boost

I performed a cursory search and was not able to find much on this board, but feel free to point me in the right direction if I missed something.
I have always wondered why the MTU is set to 1428 in System>>Build.prop file. Knowing that my desktop computer does just fine using an MTU setting of 1500, I decided to test the impact that setting the MTU to 1500 would have on 4G LTE and Wifi speeds.
The results were surprising, but may not be repeatable for those who wish to try this. I live in Southeast Houston, which may help some of you to decide whether or not to try this. I accept no responsibility for damage to your phone, business, life or anything else if you do.
MTU 1428 (90+ Days)
4G LTE: Average 7-13 Mbps Down, Record 18 Mbps
Wifi 802.11n (Asus RT-N56U): Average 10-20 Mbps Down, Record 27 Mbps
MTU 1500 (24 Hours, Limited Data)
4G LTE: Consistent 17 Mbps Down
Wifi 802.11n (Asus RT-N56U): Consistent 13 Mbps Down
I realized a 5+ Mbps boost on 4G LTE Download speeds (Results will vary)
Standard Caution - back up your phone in case something goes wrong
Step #1 - Use Root Explorer or equivalent to create a copy of System>>Build.prop and place copy on SD Card (I use the Download folder)
Step #2 - Open the copy of the Build.prop you created and locate the default MTU entry, which should be 1428, change this entry to either 1492 (DSL) or 1500 (Cable) and save the change
Step #3 - Use edited copy of the Build.prop file to overwrite the one in System>>Build.prop
Step #4 - Reboot your phone and test your 3G/4G and Wifi speeds for improvement/degredation and repeat steps above to find optimal setting (Max=1500)

My buddy works at the Columbus Vzw building and is a 4G engineer. When I spoke to him last week he JUST mentioned the MTU as well and said its going to be changed with an OTA radio update. He said theyre always working on radio updates but whether or not they are all released is another question ha.

I forgot to mention that my 4G LTE upload speed average increased and became consistent as well. I am now seeing 8 Mbps Upload in a location that had averaged 3-5 Mbps before I changed the MTU to 1500. My Wifi is limited to 2-3 Mbps Upload, so I am not sure how my Upload speed would be on a connection with more bandwidth.

I've been running 1492 since you posted it and giving it a try out. Doesn't seem to help the tether speed, but helps the phones speed of loading pages in the browser, tapatalk to servers, and loading news much quicker.

Glad to hear! I have used this tweak for years on Windows computers, so it makes sense that it should work on our phones as well. My only concern was data fragmentation, but that does not seem to be an issue for me. Mileage will vary though, so improvements are not guaranteed for all.

Been using stock since day one, today just broke 60mbps here in NYC:

The easiest way to do this on a Windows computer is to visit Speedguide.net and run the TCP/IP Analyzer utility (Link on Bottom-Left of site's main page), then, if needed, download the TCP/IP Optimizer. This utility is a portable app, so there is nothing to install. Just remember that a reboot is needed for changes to take effect.
Here is the manual method for setting MTU on a Windows computer:
1. Open a command line window as an Administrator (ie. Right-Click on All Programs > Accessories > Command Prompt and select Run as administrator)
2. Type the command 'netsh' and wait for prompt
3. Type the command 'interface' and wait for prompt
4. Type the command 'ipv4' and wait for prompt
5. Type the command 'set subinterface "Local Area Connection" mtu=xxxx store=persistent'
6. Reboot
Hope this helps. I know a lot of Windows tweaks, including many Registry settings that are not well known. Perhaps I will put together a self-help document if there is any interest.

Using the newly leaked 906 radios, my download speed jumped from 17 to 40 Mbps yesterday on 4G LTE! Upload & Wi-Fi Speeds remained unchanged for the most part.
I didn't believe it at first, so I reset the MTU to 1428, rebooted my phone and my Download speed returned to the 13-20 Mbps range. Changed the MTU back to 1500, rebooted and jumped right back to 40 Mbps.
I encourage others to try changing the MTU setting to 1500 (For those using Cable) or 1492 (For those using DSL)

stupid question here, but would this increase speeds while in a 3g area or the mtu specifically for 4g data rates?

MTU is not specifically tied to either 3G or 4G. In fact, this setting is used on Windows based computers all the way back to the early versions of Windows. MTU is used to optimize the connection between the host and client. If MTU is set too low, bandwidth is reduced because more packets of data are managed. If MTU is set too high, fragmentation will occur and there will usually be a need for more re-transmissions of data. As a rule, 1500 is the Maximum MTU setting for cable based internet, while 1492 is the maximum for DSL.
"A larger MTU brings greater efficiency because each packet carries more user data while protocol overheads, such as headers or underlying per-packet delays, remain fixed; the resulting higher efficiency means a slight improvement in bulk protocol throughput. A larger MTU also means processing of fewer packets for the same amount of data. In some systems, per-packet-processing can be a critical performance limitation."

Everything you said is correct, but just to elaborate for those that might get mixed up, MTU has *nothing* to do with windows itself nor did Microsoft create the protocol. MTU predates Windows by some years and was set up as part of the greater Internet Protocol and OSI Model by DARPA in the late 70s/early 80s.
In theory, a larger MTU is a good thing, assuming the connection can handle the larger MTU. Slower connections trying to handle a high MTU can cause a bottleneck and lead to less efficiency than greater though. When that happens, it has to slice up the data units into smaller pieces (fragmentation).
Think of it as like having to carry a stack of bricks from one end of your yard to the other. Sure, if you're strong, you can carry a ton at once, but if you're not and you try to do so, you're going to have a heck of a time getting them from point A to point B and probably end up having to split up the load, slowing yourself down as you do so.

Thanks for filling in the gaps. I sometimes skim over information that requires a little more clarity, so I thank you for chiming in.

Edit: Nevermind. I changed to 1492 cause I use DSL at home so we shall see if I can get some better speeds with this change.

Guys you're forgetting your LTE service is not DSL. If you're changing MTU which by the way is "maximum transmission unit" and have been in existence way before Windows, use 1500. LTE is a flat IP based technology, and it doesn't matter if your home (WiFi) connection is DSL, you're using Verizon's 4G LTE and that's where you're applying MTU. 1492 is used on home computers that are wired connected to a DSL modem.

I'll change it to 1500 then. Thanks.

btw I've been using stock since the launch date, and am seriously considering rooting for the first time after seeing this post. MTU can definitely help the throughput and I've been wondering for a long time if tweaks are possible on Android platform.
I know it's sounds noob (and when it comes to rooting I am) which leaked radios currently give the best data performance?
this is what I'm currently seeing on my Bolt: http://www.youtube.com/watch?v=RTwRm3QMqUs
I wonder if I can get closer to that 73.6mbps maximum theoretical throughput.
Thank you.

You must live underneath a cell tower. Lol. Highest ive seen on my phone is 25 down and 10 up.

It's NYC lol. Every corner has some kind of pico cell and it's usually fed by preexistent fiber. NYC is loaded with dark fiber.
Still trying to figure out if I should just root and flash with that latest Gingerbread RUU or should I just keep it stock. I'm just trying to get the best possible data performance, don't really care too much about the features of the ROM.

This is true for 3G/4G, but not when the phone is connected to Wi-Fi. A max MTU setting of 1492 is needed when connected to a Wi-Fi network that originates from DSL.

Ping (Latency) highly variable on LTE?

I've noticed lately that my ping at home is significantly worse than it is at work. If I ping google from work, I get 90-110ms latency. If I ping that night from home, I will usually get double that, in the 200-220ms range. This is all on LTE, using terminal emulator to ping google (dns resolved).
What I can't seem to figure out in my own testing is whether it is the time of day or something about the tower that I am using that causes the difference. It seems that on the weekend most of the time I get the poorer ping (~200ms) , but if ping is worsened by heavy load on the network, then it is not a very good test because load should be higher on the weekend (assuming here).
So, does anyone have similar exprience? Are there any tips or tricks for lowering ping ?

i've had it be weird also... and often times in the same location. i'll be at home and try, it'll be around 80 - 90.. then like 5 minutes later i'll try again and it'll be 200... and will just go back & forth even though signal strength remains the same.
possibly due to traffic.

A) Your pinging essentially a "wireless" router.
B) "Ping" is typically set to use the lowest priority if not disabled altogether on most networks.

Also dual-core brings a humongous improvement in latency. Try Bionic at the store next to the Bolt.

[REF] Tweaking the GPS for Speed and Accuracy

I don't take credit for this, I'm just basically confirming that if you are inside the US, the following tweak should improve lock speeds and accuracy. I was able to lock on inside my house < 10 secs, with a 6 meter accuracy. It's been done on a number of phones -- just posting it for the folks here who haven't found the tweak yet.
It requires root - see the threads in this forum.
To install it, you should create a backup of your /system/etc/gps.conf file before doing anything. The easiest way is to use Root Explorer and then copy the file to somewhere on your sd card. (Make a directory, or put it in a safe place).
[ Edit: Sorry, I'm having trouble getting the new file attached - the links below work (I think) but look sort of funny ]
Download and unzip the file View attachment 784134, then copy the attached file to /system/etc/gps.conf. Reboot or power off/on and you are done. (Again, use Root Explorer if you aren't comfortable enough with terminal/adb shell to do this on your own.)
Alternately you can edit your existing file with the text editor of your choice. All you are doing is replacing the NTP server and adding the SUPL lines at the bottom.

My phone already does this, even while indoors. Has anyone been having worse GPS quality?

Mine was at 25ft previously. It's been reported on quite a few forums to improve both lock time (mine improved here as well) and accuracy.

Two seconds to first lock with 3 sats. 4 seconds later floating between 9 and 10 sats locked.
F'n sweet. No tweaks needed.

I don't know about either of those phones, but I had the Captivate which was pretty horrible. both the SGS2 and the skyrocket are excellent right out of the box with none of those problems.
This post was meant to be about getting that last couple percent of accuracy and lock time, or to possibly help if someone had a restricted view of the sky via the SUPL lines at the bottom of the config along with closer geographic time servers. I've used the GPS heavily in the last couple of weeks and it's been terrific.
( Obviously the Skyrocket was only released this past Sunday, but I was using the OGS2 prior to returning it for the Skyrocket upgrade. )

Very good to know. I am actually one of those that has issues getting gps lock in my house not sure even this will help considering I have a tin roof. Still good to know that this has good GPS out of the box.

(wave) Hi
On the topic of this thread,
I did some disassembly on the GPS kernel module, and it is looking at 3 seperate config files for configuration infos. /etc/gps.conf, /data/data/angryGps/secgps.conf (i think there's a com.android in there, have to go double check, don't remember from memory) and /etc/loc_parameter.ini.
loc_parameter.ini appears to be the most interesting one, with a number of previously undocumented configurations. Notably the GPS is always defaulting to start up in "driving mode" vs. "pedestrian mode" which anyone familiar with the function of GPS will know means there is a filtering algorithm active to prevent some GPS updates from getting to the user (if the location has not moved more than 5 meters in any direction since the last update, assume this falls within the margin of error and report no movement)
Pedestrian mode is desirable in many cases as there are no GPS reports filtered out and you get the constant position updating every second.
Also the GPS driver reports 1Hz update mode, which is common for consumer level GPS receivers. More expensive/higher level receivers can report as fast as 3 times per second. It might be possible to tweak our GPS to perform similarly (boy wouldn't that be sweet)
Lastly, the GPS driver defaults to full verbosity in logcat output. This might be slightly detrimental to performance and flipping a simple bit in loc_parameter.ini cuts the amount of output by a large amount with every position update.
Out of box the GPS daemon is configured to use AT&T's SUPL server, so switching to google's SUPL server should actually be detrimental to GPS time-to-first-fix performance, since AT&T has a much more accurate geolocation database driving their SUPL platform vs. google. Outside of the US however, I imagine google's SUPL server will perform better. Also, outside of AT&T's data network their SUPL server is not accessible, so this is another case switching to google's SUPL server would be advantageous.
Further disassembly tonight

Da_G,
Thanks for the very informative post! Glad to see someone well versed in the subject commenting.

This does sound pretty interesting and worth playing with. Is there an easy way (like killing a process, like in system panel or from a terminal) to get the process to reread the config file short of a reboot? I have no idea if mobile phones can take a kill -HUP <pid> and reread, or just a -TERM and the system restarts it.

That does sound interesting - I wonder if the "pedestrian" routing on google maps actually does something besides changing how it routes - maybe it also changes the gps functionality as well?

Good to know. What amount of time do you think the first fix might be delayed, order of magnitude wise? (1s, 10s, etc.) I'd trade a short period of time for better global/rural data possibly, but it's good to know the trade offs.
