[Q] Galaxy Tab and bluetooth internet FROM other phone - Galaxy Tab General

I have HTC Touch HD2 with wonderful internet and voice rate. But I cannot connect Samsung Galaxy Tab to cellphone via bluetooth to get internet from HTC HD2.
Is there any solution (as it was made with archos tablet)?
This article sheds some light that it possible. But how to get PAN and DUN bluetooth profiles from archos firmware?
I made adhoc WiFi available according to this guidance.
But WiFi consumes a lot of power.

Do you really think Wifi will consume much less power than Bluetooth ?

Yes. I absoluteley sure. I saw a table of comparison of power consumption.

OK I guess it doesnt ahve the same range of action, that would explain why. What about the bandwith ?

The point is more options never hurt. When i had a Nokia N800/N810 and a 12" PowerBook i used to tether them to my Treo via bluetooth 'cause it consumed less power than using WiFi to tether on both ends. Now this was years ago and even on an NYC bus going 30 - 40 mph streaming internet radio and general web browsing it was just fine.
Range is not a concern, how far am i from my phone that is in my pocket/bag/shirt and besides bluetooth has a range of about 10 meters (~30 feet).
I have an Epic 4G and just decided to get a 3500mah battery on eBay. Dang thing lasts 2 days with regular use, and with the wpa_supplicant mod to my tab for ad-hoc, i'm golden for hours of wifi tethering.

I agree the range wont be an issue. I was thinking about doing the same as you and held off because of power consumption (It's already borderline on modern phones, so can't imagine what will happen if Wifi is sucking the juice out of the device)
That said you may be better considering the Playbook from Blackberry. It seems it is exactly what they plan to do and you can probably trust them in terms of optimization of power consumption

WiFi dissapointing

Went into college today for the first time with my new HD. Two of the folks in my class have iPhones.
Anyway, from the start of the day, the colleges wifi was coming and going on my phone, the signal strength was barely registering and I could not browse at all. I went into WiFi advanced settings and set power to full, this made little difference.
Both my friends with iPhones were able to browse happily.
I'm now home and deciding to check out performance here. I've just gone back into WiFi - Advanced, made sure power was at "Best Performance". My battery is at about 70%. All I'm getting is 3 bars of signal strength, varying from about 50-60% signal.
Here's the problem, I'm only sitting literally 6 feet from the router. I'd call that f'n lousy.
My laptop shows a connection signal strength of 100% / Full Bars / 100%.
So WiFi signal strength is lousy at College and lousy here at home. Is there anything i can do ?
I experience exactly the same reception quality with my HD. But for what its worth, this is exactly the same performance I got with my Touch Pro and my TyTn II before that.
.....mmmm yes I had a tytn and it was bad compared to my great xda2i...
I wonder if it is something a radio update could solve? i'm getting my HD thursday!!
If you plug in your headphone, does the signal strength improve?

No, and I even tried connecting to external power. made no difference. I also notice that if I tilt the HD a bit this way and that the signal drops even further. I have had it here at 15-20% while sitting 6 feet from the Router.
This to me is a deal breaker, I dont think I can live with this. Its bloody awful, and I hate the way it kept dropping the wifi connection in college.
Hmm not sure of the problem, my Wifi signal strength is pretty much equal to my PCs, im 20 feet away and get 80%.
I've never been able to get reliable wifi on my Tytn. Sad to hear the problem persists in a handset I was considering moving up to.
I'm satisfied with the signal strength. Yes, it is weaker than on my netbook or my notebook, but I use the "Best Battery" mode and I get around 80% signal strength 15 feet away from my router.
Ugh say it ain't so.
I use the WiFi to listen to internet radio around the house.
I've not experienced any problems even when upstairs at the furthest distance from my cheap-n'-cheerful Netgear router. At this range, the signal will have to pass through several brick walls.
Having discovered the signal strength readout in the settings, I notice that it does not read very high, but this doesn't seem to adversely affect the performance.
As far as I am concerned, the WiFi is "fit for purpose" and doesn't seem to differ much from my laptop.
Maybe your wifi is defective... Mine works fine with walls between me and the router, my TyTN II also has no problems, my old TyTN used to drop the connection as soon as it connected, was useless for wifi.
Hmm
I'm sorry to say that my wifi on the HD works fantastic. It even picks up wifi networks my netbook deosn't. I use it all day long at home then connect when at work.
I don't care what the signal strength is in various rooms I just get on with it. Having said that its 3 or 4 bars in all the rooms so all good here.
What sort of Routers are you having problems with?

I'd like to hear from ppl who have tested the device within a weak WiFi zone such as my room in college.
My experience was that it drops the network. Literally would drop it as soon as it had connected. I was nearly crying. In the same place, my laptop and my mates iPhones work grand. So maybe some of you could test it in weak zones.
To those of you defending it and saying its fit for purpose, please dont forget how much we paid for this thing. I would have expected decent WiFi. It clearly isnt! Another thing that dissapoints.
Regarding what kind or routers I'm usin, DLINK, Netgear and I aint got a clue what they run in college. But thats not the point, the point is that in my place of work, the only device that does not work at all is my VERY EXPENSIVE Touch HD. Everything else (laptops, iphones, other phones) works. That makes me kinda sick
I've had very good signal at home and at work where its a big building. I think something might be wrong with yours try to have it exchanged.
I don't have the device, but on my Artemis I can select how good the wifi works, either auto, battery optimized or full power. Whenever I select full power it gets a better signal. Maybe you have such an option on your device too?
I have connected to about 4 different WIFI routers without problems.
The furthest was about 50 meters away with solid walls... Perhaps there is a fault with your HD? Consider returning for a replacement and see if it's any better.
objective opinion
theoretically, Touch HD's (and most of the HTC's phones) should have weaker wifi performance than iphone. Performance = throughput and/or ability to lock onto signals and/or range.
reason: touch hd uses TI (Texas Instrument)'s wifi chip, lab testings shows about 12 mbps
iphone uses Marvel wifi chip, lab testing shows 18 mbps.
TI chip is much cheaper in price than marvels, that's the reason why HTC chose them.
that being said, i have seen weak wifi signals in my house, where it would see the AP, but can't associate (at certain spots). but for me, once it associates , it will lock on pretty well. wifi through put is definitely weaker than iphone, despite the CPU advantage -> 528 MHz, vs. iphone's downclocked 400 Mhz (from 667MHz)
also, your school would uses enterprise AP, so it's either cisco or aruba. but it should not make a difference. the immediate remedy for your HOME, is to go into the router's console and change the channel away from the default 1, 6 or 11. those three channels have the most interference, because most ppl don't bother change them, so your neighbor would be on those channel too.
Mine seems to work 'ok'...
I live in a 100+ year old house, so the walls are pretty thick!
If I'm in the bedroom furthest from my router, my laptop gets a weak signal - and my HD does too (just about enough to watch YouTube with only a very occasional break)
So it certainly seems no worse - and considering that HD have squeezed a laptop into the size of a flattened fag packet, I'm happy enough with that

I don't exactly have that situation but:
- I use a US Robotics access point
- When sitting 6ft away from it, I get near ~100% signal strength, as you would expect
- Through some walls I get only a very slight decrease in signal strength
- My phone often picks up access points that my laptop (macbook pro, has quite reliable wireless) in other homes which are separated by thick concrete walls and easily 30 to 60 feet away
- At the office I can use my wireless outside, if I'm at least close to the building
- So basically it works as efficient as the wireless on any decent notebook I've used, which usually have stronger and better powered receivers than phones

True, you must expect nothing less than good performance, and as stated by many people, you can also expect the HD to offer that performance, it is simply there (well on the average HD). Something must not be working right, either the radio version, glitchy software, or in the worst case, the hardware is faulty, it happens on the best devices. If your wireless receiver has a hardware fault causing it to conflict you will see these drops as the device randomly disables en reenables all the time.
I'd suggest making use of your warranty while you still can.

Tether Nexus One to iPad?

Heya,
I am getting an iPad and want to tether. I have root and can wifi tether but wouldn't that kill the battery life on the N1?
Is there any better options
Tethering takes ~10-15% of battery per hour. Depends on the quality of your connection.
If you want to tether - you need to tether. No better or other options. And it doesn't require root.
i have done the tethering and it works good, it was not for a long period of time so i cant give you accuracy on battery %..
does the ipad have usb port by any chance?
no it does not..
I use my N1 to tether it to iPad all the time & it works great on 3G or Edge (Bit Slow on Edge Though) I usually keep it charging while tethered if I can as stated above it really does suck the life out of the battery.
i do this all the time with my ipod touch 4g. it works amazingly.
Works great for me. But if you want a more refined solution, you should probably go with the iPad with 3G and WiFi.

sure, if you can shell out how much more for the 3G option of the ipad, and then another monthly data charge, on top of the one thats already getting paid for on the N1...

Since you're a Bell customer - talk to Bell about getting the 6GB plan where for an extra $10 (I think) they give you a micro SIM to use in the iPad and share your data plan between both devices. You shouldn't even need to sign a contract to do so.
Are you on FroYo or using the Wi-Fi tether app?
The Froyo tethering uses hardly any battery life compared to the earlier modded ones. Use Froyo and maybe carry another battery if you want to tether.

Bluetooth tether or WiFi tether?

Which is more efficient?
Sent from my Nexus 7 using xda app-developers app
my thought would be neither: USB tethering i (guess) would be better for battery life, but would like to know for sure - wifi and bluetooth just seem to scream 'battery eater' on the phone, and i have a tethering plan and want to get the most out of it. bluetooth may use less juice than wifi but connection may not be as good.
anyone know if its possible to USB tether from android phone to NEXUS 7 ? or if its worth pursuing??

I tether from my galaxy nexus to my n7 on and off throughout the day it works perfect for me. My phone is running the vicious jellybean v1 ROM with tethering built in

Via Bluetooth you save battery life but you get slower speeds and can only connect to one device... via WiFi battery drains more but speeds are faster and you can connect to more than 5 devices depending on the mobile hotspot.

speedtest on my phone shows 3.6mbps and while tethered via BT, the N7's speedtest shows 1.6mbps for DL
Although BT consumes less power than WiFi generally ( this may not be true in the future) WiFi speeds are faster than BT s you are "on the air" for a shorter amount of time thereby potentially consuming less power. It depends on the chip set used and the implementation.
Battery life on the Nexus should be your least concern so WIFI all the way especially if you're streaming videos. Nexus 7 is perfect WIFI tether companion for my HTC Thunderbolt on LTE.
ive been using foxfi with pdanet on bluetooth and it really saves on the battery!!
Well more concerned with the battery of the device I was using the tether with, my Galaxy Nexus.

both are using battery constantly listening for new events. actually SyncSMS is most efficient since it uses Push Notifications to tell the other device when it should sync a new message
Are you referring to tethering? bluetooth uses less battery but i believe wifi is stronger

Bump this. Anymore opinions?
I would say Bluetooth, Wifi always drains my arc a lot quicker than Bluetooth does, when it's connected.
Just look at tethering, bluetooth uses a lot less power than wifi does

HTC One first to use Broadcom 5G WiFi

Interesting read about the new chipset.
83% batter improvement and faster WiFi N speeds. Lets just hope the range is good, because every phone I ever had has had the crappiest WIFI range.
Yeah, read that, really cool, but I think that router will be expensive

It's probably very immature of me to find typing errors amusing, but I just love the idea of a phone that improves the quality of pancakes.

I just tried saying better again three times into my phone and it spells batter....hmmm. maybe I need to see a doctor LOL
A quick google shows AC Routers ranging from £135-190 ish....
I just did a test using my Asus router for Wifi download speeds. I am quite impressed but one has to be near. Noticed that when I walk about 15-20 feet from router it drops connection

That's insane!
Although I don't have an ac router, I have also found wi fi performance to be very good if configured to use 5Ghz band

The DNA now the One have the best wifi range I have ever had. On my S3, it was terrible.
