Attension GPRS Dial-up Users!!!!

[Gigacore]

If u r using GPRS Dial-up to connect to internet for your system via ur cellphone and facing Low speed here there is hint to Optimize the Speed.

I use Airtel Mobile Office @ 20Rs/Day in Bangalore which gives a smooth access. My SE W810i's EDGE gives me the speed above 380 Kbps and Download speeds of 40-58 Kbps (Without EDGE 115.2 Kbps Browsing and 4-8 Kbps Download Speeds)

Before using SE W810i, i used to Connect Via SE K508i and was getting the 115.2 Kbps Speed and 4-8 Kbps in free time. In peek hours i used to get 1.2-3 Kbps.

So i came up with a plan to inscrease the Signal Reception during Peek Hours with some unwanted old stuff in the House.

All u need is:

- A lengthy old Antenna for TV or Radio (2 Antenna of abt 1Meter is Recommended)
- A Standard Speaker Wire of about 1 Meter (Transperant with red lines)
- A Spring of 5 to 10 mm
- Two Mousqito Coil Stands
- Blade
- Tape
- Scissor
- A Small Cardboard Box to fix the Antenna (CPU box Size is Ideal)
- A Metal Stip of ur Mobile Phone size.

After gathering all these stuff follow the procedure:

1. Make two holes on the Cardboard Box using Antenna and Fix it, leave about 3 Inch Gap between them. (If u have One antenna then fix only one)

2. Open the box, so u can see the two Antenna's legs inside the Box, Slide the antenna upwards a bit and fix the Mousqito Stands in betweent a small hole in the mousqito stands so the antennas will not shake.

3. Take the wire, Cut 3 Pieces of 10 Inch Wire and Peel it at both the ends.

4. Make a hole between two antenna's on the box.

5. Tie the peeled wire at both top of each Antenna, and open the box at bottom and connect two wires to two stands at any place u desire and take the two wires out of the box from the center hole b/w antennas.

6. Take the spring and place beside the hole and connect the two wires that u have taken out from inside the box and tie the wires at both ends of spring.

7. Take an another wire of 5 inch, peel it and tie it to the center of the spring.

8. Take the Metal Strip and make a small hole using a nail and a hammer, Connect the Wire that comes from the spring.

9. Place the Mobile on the Metal Strip connect the Data Cable or IR or Bluetooth (Datacable is Recommended)

10. See the difference.

Any doubts regarding this can be commented...

Refer Diagram



Observe the Speed @ the time of Download using 115.2 KBps Connection:

I might try it on my reliance mobile for R-Connect.

[Gigacore]

Sure u can try it @ Harvik780

Ok man, looking forward for ur result. But i'll say u may get 4-6 kbps in Peek Hours!!!

[great_manish]

mobile office in calcutta gives me peak download speed of 16 kBps...comes for 250 rupees a month .... unlimited bandwidth...not bad huh ??

[Gigacore]

Ya not bad without EDGE in culcutta, but if u review the net traffic in Bangalore its Worse.... gr8 manish

[infra_red_dude]

can u post a screenshot of the finished product? it'd be much easier for people to visualise the same.. and help during the construction procedure....

My Finished Product Looks crap so thought of posting Diagram!! Nice Responce!!!

[Harvik780]

I got a max of 14.1 KB/sec during night (after 2:00am)and a max of 4.8KB/sec during peak hours(10pm as it's the time when the cost/hour drops to half).

[infra_red_dude]

doesn't work on my dad's cell! din exactly make like this but the idea was largely based on it!

[Gigacore]

Which network is ur dad using @ IR Dude

[int86]

I think this will help only those who are in not good reception area. i.e. they do not get full tower on their mobile.

[sankaranand]

Thanks for the tip, i posted about it in my blog.

[blueshift]

I have MO Unlimited @100/-. Sometimes get good download speeds of 20-22KBps in Limewire and download managers.

@giga can u pls post a pic of the setup.. The diagram isnt too helpful

[infra_red_dude]

Airtel here.......

Nice Job, thanks for posting it in ur blog..

I think the handset and GPRS class of ur dad's cellphone is either newer or older... The trick works fine in GPRS Class 10 @ IR Dude

[infra_red_dude]

he uses a z550i and afaik, its a gprs class 10 mobile! anyways, its ok. he'll be shifting soon... and broadband is the way for him!!

btw, nice tut gigacore

[naveen_reloaded]

Guys that wont change...

u can hit as low as 1kbps to max of 8 kbps...

THIS SYSTEM THEY R USING IS CALLED


----T U N E L L I N G----

SAY they have a bandwidth of 100kbps...

if use he gets all of it and is set to bound only by his phone speed

2 users 50kbps each
3 users 25kbps each
4 users 12kbps each
5 users 6kbps each

and it goes on llike this....

so getting 8 kbps is nothing a miracle...

@Intel_Gigacore

Thanks For your nice tut...

Can you post some Pic, as your mobile have a camera, isn't it?

Please post some pic of the Antena Box, It will help ppl to get clear idea.

Low picture quality will be ok.

[Josan]

Hey man thanks for this alll but can you plz tell me that wat is Mousqito Coiand how it looks

[Gigacore]

u dont want a Mosquito coil, u require a mosquito coil stand. Mosquito coil is coil used to light up in the night to aviod mosquitos.. You can buy it from a general store. You wont get a mosquito coil stand but u can buy one mosquito coil for 2 Rs and request to give a stand. The stand will have a flexible arm with two folds, the two folds have a holes at the center. so if u make the those arm as shown in the figure u can fix the antenna using its holes.

[teknoPhobia]

600 bucks a month for what is basically dial up, why would anyone in their right minds use it?

[Gigacore]

but u cannot tie a Broadband cable or an wireless Broad Band Phone from airtel where ever u go.. 600 Rs is worth coz a GPRS based gives 115.2 Kbps where as EDGE gives 236 Kbps anywhere the network is avialable. Only one doesn't have rite mind thinks only the drawbacks!!!

[amitava82]

Airtel kolkata has better GPRS speed than bangalore. right now i'm using and its pretty good compared to bangalore. during pick hour in bangalore, while a page loads you can take a nap BTW CC in Kolkata REALLY REALLY BAD..

[freshseasons]

I still dont get it! I mean why will some antenna help in increasing the speed.If you have all the bars on the mobile it ain't gonna make any difference.
Ok if there was some hardware mod or some software where we can by pass he ISP i will really appreciate.But this antenna thing is bizarre.
The only bottle neck in Gprs ( Hell in most of the connections too)is the ISP and simply increasing the range of the phone is not going to help.Moreever if you already have full range its more helpless.
Still one thing.CAN YOU PLEASE POST THE PICTURE FROM YOUR CAMERA.
I want to see how it looks cuz on my farm where the mobile signal is really weak this may be useful to make decent calls.
So POST THE PICTURE !

Doesnt it use up the battery? How long do you think it will last on N70 ?

[Dipen01]

^^ u are damn right there..!!

It sucks the battery.... wen i get the best of speed i.e around 27-30 Kbps... my battery is out in 4-5 hrs flat..!!

i dunno about N70..but i am using W810i
