Bluetooth Modem to Laptop HSDPA Speeds

I am supposedly in a UTMS/HSDPA zone (Detroit MI). The phone show me a "U" in the status bar. I've read the speed is around 1.5Mb/s. But I am getting only 30KB/s - 50KB/s MAX using the Hermes as a bluetooth modem! This sucks!
Is this speed limited by bluetooth? If I use the phone as a USB modem instead, does that increase the speed significantly? It's a much more involved setup to do this however.
Or am I missing something? These speeds are atrociuos for what I am paying. I expect MUCH MUCH higher speeds. Please someone enlighten me or I am going to cancel the stupid service.
Very frustrated. Thanks for any input.

Anyone?

I have the same problem via USB, here 60 miles north of Manila, Philippines. Best I can figure, it has to do with the radio stack being used...? I am using Orange m3100, but my buddies in Manila using Dopod 838 Pro and/or Universal, get real 3G speeds with no special settings...

What version of BT is on your laptop? Older versions than 2.0 are very slow. I use USB and get 700 Kbps avg with 2 bars of UMTS in Bay area, CA.

anubus12 - partly the answer gave you Chirunavvutho. Check what kind of BT adapter you have in your computer, which version.
Go to http://en.wikipedia.org/wiki/Bluetooth for details about versions and about speeds.
But, in my opinion and my practice BT option is much slower then USB connection. First of all all interference with other radios (especially WiFi [same bandwith], and other apliences like CRT monitors and TV, microwave ovens even fridge - it sounds weird but they do interfere.
Second - when your device has to be like a midleman, and has to use GSM/WCDMA radio to get information and then send it by BT radio it will limit it's speed. Actually both speed end efficency. That is why it is better to use USB.
Third - I do not know which version of HSDPA has Cingular in your area. Remember that even if they have 3.6 Mbps speeds may be much lower, due to many reasons - lot of users, kloged backbone etc.
Forth - for info on HSDPA go to: http://en.wikipedia.org/wiki/HSDPA
drummer10630 - find out FieldTest_157 here on xda-developers. It is monitoring application for Hermes. Find if you have HSDPA in your area. Remember that pure UMTS (WCDMA) has only 384 kbps. This app will tell you what kind of connection you have. You have here also manual if you do not know what to look for.
Hope this helps you guys

No EDR
The Hermes/TyTN supports Bluetooth 2.0 but not EDR. The maximum speed is 721 kbit/s, or about 90 kbyte/s.

My buddy has a PCMCIA Card with EVDO Rev0. I put it the same computer and got constant DL rates at around 100Kb/s. That is very acceptable.
Using BT 2.0, it's horrible. I don't get anywhere close to 90Kb/sec.
So now, it might make more sense that USB would yield higher download rates. MAYBE.

Thank you very much for the clarification. I'll check USB out to see if the x-fer rate is faster.
As to FiedlTest_157, I downloaded the manual and can't really make heads or tails of how to read it. The manual gives you some parameters, but how do I know what type of connection I have? UTMS/HSDPDA or EDGE?

anubus12 - let me tell you few things and then I will answer your questions. OK?
If you want to have fast data access for your PC - use PCMCIA cards or build in systems - IBM has few notebooks with it, other I do not care
I can assure you that it will be quicker then any connection via USB/BT because hardware and software (drivers and apps) are dedicated only to handle DUN (dial up networking).
So there is no point of comparing PCMCIA cards to PocketPC telephones. Especially when you are using two different networks.
I had HTC Apache in Sprint and Hermes in T-Mobile/Cingular and then I can tell you that Sprint network is simply faster then Cingular. First of all Sprint in my area is fully EVDO-Rev.0 and Cingular is UMTS sometimes HSDPA or EDGE depends on radio used, interference, or even air (windy/raining/t-storm - it has some influence).
HTC Hermes just like other PocketPC handles DUN well, but it is more like backup connection, not when you need it all the time. Just get the info and finish connection. Not because price per MB but they were not build to work this way. You need PCMCIA cards for that purpose (constant net access).
Most of people here might disagree but if you are not traveling internationally on regular basis - use Sprint or Verizon - it is faster and more reliable. Sorry guys its the truth.
When T-Mobile will start 3G it might be different thou T-Mobile has expirence in other countries but other networks has this advantage.
If you traver internationally then you have to use Cingular or T-Mobile. For corporate use I would choose Cingular for personal T-Mobile.
My point is that you cannot compare something which is not comperable. Back to your questions.

OK, let me put it in the easy way
You have Cingular so your only choice is UMTS/HSDPA (3G) and EDGE (2G) because Cingular claims that it's network is fully EDGE enabled.
When on top screen bar you have G (or when using aku 3.3 - E) you are going to GSM (for basic data), AMR (for speach codecs), GPRS (for data connection).
When on top screen bar you have U (or when using aku 3.3 U or H) you are going to WCDMA (for basic data) or HSDPA CQI Status (for knowledge is HSDPA is in use). Well if you see H (aku 3.3) you know that you are in HSDPA area. But if you are using aku 2.3 you are going to HSDPA CQI Status.
You have to know that GSM/GPRS/EDGE data are time and usage driven due to it is TDMA network (Time Division Multiple Access). It means that network data are given to you every few seconds. Because data transfers it is usage then when you are finished data is 0 because nothing is happening. You have to monitor during transfer.
UMTS/HSDPA data are event driven due to it is CDMA network (Code Division Multiple Access). It means that you will see something during and after event. Like after download, but you have to have FieldTest open during download to record data. You are in HSDPA when after/during download in HDSPA CQI Status group CQI1-10 fields are more then 0.
Hope this helps, if you have more question just ask

I use both bluetooth and usb on the cingular network with my tytn.
And yes, bluetooth is much slower than usb regardless of the type of bluetooth on the pc.
I usually get 300-400 on bluetooth and 800-1300 on usb. higher speeds with vista vs xp (don't know why tho) I doubt you will ever get 1.5 mbs as you mention, unless you are the only person using that particular cell tower

@Pawlisko....My problem is that I do get 3G speeds when using the unit itself, browsing, streaming, etc..., but when I use it as a modem for my laptop, from the same location, during the same time frame, I only get one tenth the speeds. Are there different versions of the USBMDM.inf that would cause such a thing? I have experimented with init string settings, and for some reason, using NO init string gives me the fastest speeds.

eagle 1 - By your end of quote I can tell you that still you are thinking old way
Huge advantage of CDMA is it's multi connection to tower bases. There is no handover like in TDMA system. In large city your cell might be served by many towers (TyTN 1 to 6).
HSDPA is regarding of category 0.9/1.2/1.8/3.6 Mbps (current). During 2007 CeBit in Hanover 7.3 Mbps will be shown. It will go thru 10.2 to 14.4 Mbps (max) in near future. Of course like any other link you have to substract overhead of TCP/IP protocol data of avg. 20%.
Like fast ethenet - suppose to be 100 Mbps = 12.5 MBps, if you will get 80 Mbps = 10 MBps of real transfer you have very fast network.
If you have more questions - ask

drummer10630 - did you check your speed using any speed tester? Sometimes speed is relative. Remember that some pages are optimised for PDAs with less ads, better html coding etc.
First of all - do not change anything - no strings. Just put your APN in TyTN and dial *98# should be the fastest way.
Second - check if you have installed in your computer software like IM/update that will use some band without your knowledge. That can kill your connection for good.
And last - delete everything for comp - inf files, and related dlls. Install one more time and do not change anything. As plan as it can be.
As usualy - if you have more questions - ask

I can get about 70KB/s download with my laptop's built-in bluetooth module ( 2.0+edr) and tytn and about 150KB/s via usb ( i'm in Italy with VODAFONE operator ).
Using a 1.2 BT dongle on the pc will reduce speed at about 40KB/s ... this is the connection speed from the pc to the device and not from the device and the operator network ( network speed is independent from your pc to tytn connection ).
Just a question : how can be the tytn BT 2.0 without edr since the specs tell that only differences from 1.2 bt vers and 2.0 bt vers is only the speed increase and there isn't a 2.0 without edr in the bt specs ???

OK, let me answer.
I do not know how abubasim knows that TyTN does not have EDR but this is meaningless.
Your speeds are normal. First of all maximum speed is something which normally is never achived. Why? Because of interference, not optimal power scheme etc. Just like WiFi (IEEE 802.11g) you will never get transfer of 54 Mbps = 6.75 MBps even with protocols overhead (of 20%) = 5.4 MBps. Real transfer is 1.5-2.5 MBps.
Now BT speeds:
BT 1.2 - 721 kbps = 90.125 kBps = real transfer max 72.1 kBps so your speed of 40 kBps is normal with this type. I would said that this is good link speed.
BT 2.0 - 3 Mbps = 384 kBps = real transfer max 307.2 kBps but as per wikipedia data transfer is 3xBT 1.2 = 2.11 Mbps = 270.375 kBps = real transfer max 216.3 kBps so your transfer of 70 kBps is roughly 1/3 so it is about right. I would say that 110 kBps is what you may get, if more you are lucky.
I do not know if TyTN has EDR - in my opinion it may have, but it has to be chcecked.
Hope this helps, if you have any other questions - ask

You may have meant *99# ? ;-)

@Pawlisko :
i think the tytn has 2.0+EDR also if HTC website say 2.0 without edr ( this mean nothing if you read the BT specs ) .
I was using a samsung Z560 HSDPA before ( BT 1.2) and max download speed via BT in conjunction to my 2.0+edr laptop never reach up to 40KB/s.
Now with tytn i can reach up to 70KB/s and a stable 55KB/s , i mean tytn has real BT2.0+edr imho...

Right. My bad

Something that you may not have thought of. Set the baud rate on your Bluetooth serial ports to the highest rate at which you can communicate. Mine is set for 460Kbps. It made a serious difference for me. I didn't perform any measurements but I did see the difference. The default rate is 115200. This was the mistake that most folks made with standard modems. The default serial port rate was 9600 and a 56K modem needed to have data fed to it at at least 115200 to keep its compression engine busy. It didn't matter if you had a 56K data connection if you were only feeding it at 9600. The same principle seems to apply here, at least in my case.
Just my .02.

How do you set the modem to 460Kbps? The bluetooth modem is set as a standard modem at 115200, which is the MAX. I don't see an option for 460kps. Are you saying to set it up the BT connection as something other than a standard modem?

Please post your 3G speed test results

Would anyone who has managed to get a HTC Touch HD phone be able to run a speed test and let me know what network, time and location the test was conducted?
www.dslreports.com/mspeed seems like a good place to start
Thanks in advance!

Just ran the test with a 1MB file.
Result was 775 kbit/s.
Network is O2 Germany.
Test was done inside a building, that might lower the transfer rate.

That site's not much use - I just got 500k on 3G, then 250k on wifi (on the 1mbyte test).
Testmyiphone 3Mbyte seems fairly consistent, about 1.25mbit, or 2mbit on wifi (lowest performance, best battery setting).
This is Orange btw, in a good signal area.

There was the same thread in the Diamond forum.
It turned out that it also depends on what browser you use.
I did my test with Opera. PIE seems to be slower, so if anyone of you ran the test with Internet Explorer, please re-run it with Opera.

speedtest.net, Opera 10 mobile, HD2 is slower on WIFI than on Tmous?

First I apologize if this has been covered in another post - I searched but couldn't find and if so a redirect would be appreciated.
I'm trying to determine just how fast data can be pushed through the phone and I've run into some problems.
I'm trying to use speedtest.net to do this and it was working with the stock ROM but since I've been trying different ROMs (3 of them in fact) I always get the error "Missing License Key" in he Speedtest.net window.
Anyone have any idea how to fix this?
Since that one doesn't work I've been using the Speedtest.net mini. That at least gives me up and download speeds.
But I've also found that whne I connect to the internet with WiFi the speeds are almost slower than a decent H connection.
It's rare that I get over 3 down /1.5 up on a WiFi N connection that has 20+Mbit Comcast connection behind it.
Here I'd just like to confirm if everybody else is seeing the same thing:
What dl/ul speeds are your seeing with your HD2 connected to a fast wireless router?

On the stock ROM it wasn't much higher than the 3G.

Not for me, I usually get 13-14 Mbps down/ 50 kBps (stupid cable upload speeds) up on wifi and around 1.8 Mbps down/ 1.5 Mbps up on HSXPA/UMTS.

I personally have very little faith in the reliability of numbers from speedtest.net
Try testing this way...use IE instead of opera, and go to www.speakeasy.net/speedtest (it wont run in opera but will in IE). When I use that method while connected to my home wifi, I get the exact same speed my desktop gets using the same dsl source (just a hair over 5MB down), which my 3g connection here has yet to match...usually caps out at around 3MB or so.

I've seen the same behaviour as the OP.
My Wi-fi speeds are slower than my HSPA speeds.

I had same issue as well. I had bsb tweaks installed. I disabled the wifi n tweak. after that both my 3g and wifi speeds went up. Re-enabled the tweak to see if speeds would be reduced and this time only the wifi speeds increased again. tweak must of been causing some sort of issue with the 3g and wifi speeds. Try disabling it, soft reset and than re-enable the tweak. Hopefully it works for you as it did for me.

Which ROM are you using and how much faster is it? Do you see a large speed difference with a different ROM between a fast WiFi and 3g/h?
The only real difference I noticed between the stock and 3 other ROMS I've installed so far is that I wasted a long time trying to get WiFi working in KAOS but never could. I was able to get a connection but the client never reported an IP address. Turns out the ROM I was using was not specifically for the TMOUS HD2 so maybe that was the cause.

My situation is reversed; the cable manages 3mb up on the PC but the 3G/H is almost always much slower on upload than download.

Thanks, that was an excellent suggestion; I hadn't tried this particular site before and while it uses the same data as speedtest.net it also allows a specific destination and works with IE.
In random testing on WiFi I got around 7-8Mb down, 3 Mb up. While driving around the local area I got 5 bars from two different towers and found an average 1.0Mb dl, 0.8Mb up, and that was pretty constant whether moving or stopped.
I've also noticed in general that the "H" only appears whenever data is actually being transferred (sounds like our back-end hasn't been upgraded). Right now I can get neither the speedtest.net nor the mini version to work - the windows just stay white.
I'll keep trying both of them to compare over the next few weeks but I think the biggest part of the problem is Adobe Flash. There is a reason why Apple doesn't support them and I don't think it's all political like Adobe would have us believe.
I've also done some more experimenting with mobilespeedtest.com as well as general testing over the past few days.
Mobile speed test shows that IE seems to be faster/more stable than Opera - by probably 5 to 20%. While the absolute numbers had alot of variability, Opera was unable to complete the 5 MB and 7 MB tests at all; the browser window just remained blank.
The other thing to throw in here while trying to clean up the phone I found the post about doing a hard reset and that also seemed to help. I don't have any solid data but I would certainly hard reset it again and recommend it to anyone that has changed ROMS much or done a lot of installing/deinstalling of cabs.

I don't have BSB tweaks installed currently but I performed the WirelessN tweak in the registry. Based on what you've said here I went back and switched it off, did a soft reset, tested and then back on and retested, and found no dramatic difference between any of them. What I found was a lot of variability between the tests in the same setting - even one right after the other. (I would probably do well to review the wireless router settings to see if I can up the data throughput rate.)
To compare I checked a notebook using N located at about the same distance from the router and got speeds a little (5-10%) faster than on the phone (-hardwired into the router I get 25Mbps down). This tells me the phone is as optimized as it's going to be going through my router.
So on the phone I see final scores of about 7-8Mbps down, 2-3 up, with spikes over 10 Mbps down and 4 up during the tests.

I tried "mobilespeedtest.com" and get around 1100-1300 kbps on wifi and the same or more when wifi off and using t-mobile (with "H" showing, not 3g).

No, Not on the Stock ROM.

Like Opera Mini and Skyfire, I think Opera Mobile 10 goes through an external server. One cannot get an accurate speed test that way. Use Opera 9, or better IE, as it works with flash speed tests as well, not only the mobile ones.

Mi note 2 Wifi speed limit ?

Mine Xiaomi mi note 2 never reaches more than ~ 45 Mbit on Wifi (tested with speedtest.net app). Someone also have this problem?
Rom - official Chinese 8.0.15.0, no root, no unlocked bootloader.

No issue here.
http://beta.speedtest.net/result/6106180223
(Use "request desktop site" with http://beta.speedtest.net to avoid having to download the app)
There's only a 1x1 antenna in the Mi Note 2 so using a 2.4GHz network without channel bonding will max out somewhere around 50Mb/s in practical use. Oddly about half the time it will only use 20Mhz rather than the 40Mhz it's capable of though I think this is ROM dependent and I can't think now which roms offered channel bonding. It seems pretty clear that 8.0.15.0 doesn't though.
Upgrading to a 5Ghz network will help a lot, you could also upgrade to the latest rom and see if that improves things.

[Wifi Issues] Not what you may expect

Hi all, just picked up a Tab S5E today - love the screen, built quality etc. What I don't love is the Wi-Fi performance. I'm left very confused.
I installed Android 10 right out the box and did a clean reset - after which my link speed in Wi-Fi settings shows 86 mbps throughput. For reference, my other phones (Oneplus 5 - 3 years old and Oneplus 8 Pro both show 866mbps receive and transmit speed).
When right next to the router I get a max of about 150mbps, with an average of 80mbps on Speed Tests - This is the case whether holding the tablet or not. When about 5 metres away through a wall this goes down to 45-55 Average, in comparison both phones show around 280-330 average.
When right next to the router with my other phones I get my networks full download which is 550mbps.
I understood before purchasing that if holding the tablet in the bottom left corner when in horizontal position (camera on the left) you are likely to lose signal - potentially mitigated with using a case. However, by wrapping my hands round the left antenna, on average - the speed increases to around 150-170 - odd...
When attempting to put pressure on the antennas from both ends and firmly wrapping my hands around the tablet, I do not see any network connectivity issues relating to dropouts and the WiFi bars remain on 5.
Honestly not got a clue what's happening here, either who have decently fast connections don't big this up online, or this is just a weird hardware fault with my unit.
Pretty disappointed. If anyone has any advice / screenshots of their speed results higher than this - I would greatly appreciate this, in which case I will definitely pursue a replacement device. I can't accept that in 2020 a device cannot achieve full 5.8ghz WiFi speeds when directly next to the router.

There is nothing wrong with your device. The maximum WiFi speed on the Galaxy Tab S5e is around 160 to 180 Mbit/s. I didn't expect this either when I bought this model and it is also a major bummer for me.
The device supports 802.11ac, but unfortunately Samsung only put a single antenna into it which limits it to a single MIMO stream (on a 80 MHz channel that gives you theoretical 433 Mbit/s throughput, which of course no device will ever reach). I would expect something around 220 Mbit/s with this configuration, but somehow the maximum speed I get with this device is only around 160 to 180 Mbit/s. It is not only the speed that is bad, it is also the signal strength that is exceptionally bad compared to all my other devices.
Your phones and other devices probably have two antennas and support 802.11ac with 2x2 MIMO which gives you theoretical throughput of 866 Mbit/s and around 500 Mbit/s in practice.

Thank you for your reply. I just received a replacement unit and tested before updating to the Android 10 update. There was indeed something wrong with that previous device as the link speed shows 433mbps and I consistently got 280-295mbps download.
However, I just updated it to Android 10 - now it's completely gone again. Link speed 87mbps and downloads of 20-70mbps. This is most definitely a software issue which I'll be contacting Samsung about.

I also got a WiFi issue when upgrading to Android 10. My tablet was working perfectly before the update but now will not auto connect. I agree this must be a software issue.

I have just upgraded my tablet to Android 10 and the Wi-Fi speed maxes out at 60 Mbit/s. I'm thinking about selling my device again, this is unusable.

All I can suggest is to create a bug report in Samsung members app. I did so over 10 days ago now and am awaiting a response. The more people that do so the better - a fix needs to be rolled out for this. Something's quite wrong with how the WiFi module is working after this update, probably driver related.

Has anybody tried wiping the cache partition in Recovery Mode? If that doesn't help back up your device and perform a Hard Factory Reset. That normally fixes any software issues.

With both the tab s5e's I've had I had reset them both twice, and cleared cache in recovery.
This is definitely an issue brought about with the update considering Android 9 was absolutely fine network wise.

In that case you may have purchased a unit from a bad batch.

I disagree, this is definitely a new problem that was introduced with the recent Android 10 upgrade. Samsung made the Wi-Fi signal "more stable" by limiting the modulation type to QPSK (MCS-2) instead of 256-QAM (MCS-9) which effectively caps it to 87,8 Mbit/s on a 80 MHz channel. Instead of 180 Mbit/s with Android 9 (which was pretty bad), users are now getting around 50 Mbit/s (which is incredibly bad).

My S5e won't auto-reconnect following the recent upgrade to Android 10. Also stutters and freezes for a while after restarting in various apps and settings. System software issues presumably.

Thanks for doing the research to find this out. This definitely explains exactly what I'm seeing.
Very disappointing as I was achieving fine speeds 290mbps or slightly higher prior to the update. Now WiFi on the whole is pretty poor in comparison.
Why was this done intentionally - it really makes no sense. Surely this must get reverted.

I just got an update this morning aimed at WiFi improvements

I can confirm this update has fixed all issues for me. Normal 433 link speed when next to the router and the same WiFi download speed as on Android 9.

Since updating to Android 10, I started having issues with mesh wifi (I'm using Google Wifi). Same position and setup that used to work perfectly with Android 9, now the table starts disconnecting from Wifi and I have to reboot to reconnect. Anyone else has this issue?

I'm contemplating buying an S5e tablet (in Australia). Does the reduced speed of WiFi impact on any practical applications ? My internet cable subscription is for 50mbps. It used to be 100mbps, but I dowgraded on purpose, seeing no benefit for the cost. Even at 50mbps (practically 46) we have moments like today when both myself and my son are working remotely to different employers, while my wife us watching a video. I realise there could be apps which require more bandwidth, so I'm just curious what those might be.

That is exactly my problem as well. Google WiFi and random disconnects from the tablet that sometimes get fixed by disconnecting/reconnecting but majority of the time a restart is the way to solve it.
No other device in the household gets disconnected from the network (neither was the tablet before upgrading) so it is definitely the update to blame.

Having similar issues following the update. I tend to turn the tablet off when I'm not using it, and thus far I have yet to successfully connect to WiFi on startup. I have to manually toggle WiFi to get it back on.

Same wifi issue here after updating to Android 10. Is there a way to manually update using file some were receiving in late July?

I am really bothered by this GROSS limitation too! It makes issues with the driver even worse.
Maybe our answer can be found on this page or something or nothing ?
