Ok,

So I have an adapter and an antenna, but my Samsung Charge has 4 ports. One L1R2, one L2, one R1, and an odd smaller sized one G.

Im assuming that the 3 normal ports are for its MIMO ability, but Im getting reduced signal not increased signal in each port.

Any thoughts?
[Thunderbolt General] miketoasty:
I dont know if you purchased it or not yet but Verizon sells a device that increases the signal throughout your house without having to plug it into your phone. If you need a link just say but I would much rather that from the company I bought the phone than some off brand thing that may or may not work.

Plus the Verizon would would work with all Verizon phones in your house.
[Thunderbolt General] kierandill:
My indoor experience has been exactly the opposite. My office is smack in the middle of this concrete and steel WWII-era building

and my phones have almost never shown 3G, including the TBolt.

Since 4G came on last Friday testing in Indy, I have seen consistent 4G signal. That is consistent with the lower frequency being better at penetrations. In fact, it prompted me to put the Internet Connection widget on my desktop so I could turn off data instead of watching a huge battery drain.

That said, at home in a 4G fringe area, the only way to get 4G in my house is to walk to the window facing the direction of the tower. And the signal strength holding to the glass is about 10dB higher than just a few feet back.
[Thunderbolt General] ddarvish:
hook a brother up with a job.. loookin to work for raytheon in LA.. lol
[Thunderbolt General] mattevandavis:
Yeah,

Im not looking so much to improve call quality as I am looking to get 4G on a fringe area. Overcast days we get 4G from the reflection of the clouds, so I figured if I put a yagi on it I should be able to get 4G on a normal day.

I tried the normal connector that VZW normally sells for aircards. It cause a loss of signal in every port. But I looked at my neighbors Thunderbolt and saw that it had the same little port that my phone has that is marked G.

I ordered a plug for it and we will see if I get any boost from there.
[Thunderbolt General] stealthrt:
So any good advise on making an external antenna for the thunderbolt? Has it been confirmed that the rubber round hole under the kick stand is indeed an external use for LTE antenna?

I talked with 3gstore and they recommended the use of the Wilson Electronics 801865 4G Verizon LTE Cell Phone Booster 70dB Adjustable Gain In-Building Wireless 700 MHz LTE Smart Technology Signal Booster but then again, that cost $350+.... can a simple hookup connector be connected to the phone with an outside antenna?

Thanks for your time,

By any chance you got a friend with an LG Revolution?

That phone will tell you for your dbm for 1X,3G, AND 4G.
[Thunderbolt General] loonatik78:
I drove a truck for 5 years. Wilson has been selling this crap in every truck stop in America for at least as long and I've seen a lot of people buy it. The stuff I've used (other people's stuff) really hasn't done anything that I can tell. To me, it seems like a massive marketing gimmick. The stuff that actually connects to a connector on the device might show promise, but I'm not a fan of some 6 foot coax cable hanging off of a delicate connector soldered right to my board. I'm not really sure how effective any LTE solution would be either, since the LTE specification calls for dual antennas.

Bottom line: I've pretty much everything I've ever seen come from Wilson Communications is over-priced gimmicks that lack any sort of verifiable functionality.
[Thunderbolt General] zeeza57:
I agree with the other driver. Most of the antenna stuff sold is a gimmick. I have a Verizon extender in my house. It only works on call quality. I only have. 1 EV signal at home with the extender. And it does not improve that. so I know that won't help the 4G signal get any better. But the extender does at times interfere with other cell phone calls of my neighbors within range of it.
[Thunderbolt General] stealthrt:
OK so i have heard what not to get but haven't heard what to get in order to increase my bars on the phone within the house.

David
[Thunderbolt General] loonatik78:
If having a solid data connection is a must, WiFi via broadband is certainly a better solution than these gimmicks. Until one of these gimmick makers begins showing some independent lab results, I'm forced to believe that they don't work. I've looked into this, and the best solutions are active cellular relay stations, and they aren't cheap. In this device you'd probably only get voice service as LTE is probably too new to be supported.
[Thunderbolt General] stealthrt:
I'm in the woods so i don't get hi speed internet (broadband) if that's what you were talking about. I would have to pay my cable company 7000+ for them to run a line to my home if i wanted hsi - which isn't going to happen.

4G finally got around to these parts and i get about 2 bars inside the house for 4G but it goes back and forth from 4G to 3G, etc etc. so i wanted something to at least keep it in 4G even if its still 2 bars (its still 5mb down/ 2mb up) with 2 bars.

I've seen on the back where the antenna would hook up but the reason i posted on this thread was because i wanted to know what connection would fit it so i could put a antenna on the house facing the Verizon tower location and get a better signal.

Hope that helps :)

David
[Thunderbolt General] loonatik78:
Ok.... Let me try to explain why that's not going to work as well as you think it might.

LTE is a GSM based technology which uses TDD and FDD channel access methods. What this means is that even if you could somehow rig an antenna to that connector, your LTE signal will not improve markedly because one of the key indicators of signal quality is distance from the tower. Your handset and base tower can determine this to a pretty exact figure by calculating the the signal's doppler shift and speed of light delay between you and the base. This is critical in order to allow your device to fully utilize it's assigned time slot according to the TDD access method. LTE also only allows so much delay, just like GSM. Even if you had an active relay amplifying the signal coming and going, if you're outside the zone where time delay can be compensated for, you will be kicked from the tower.

What this also means is that the quality of your service isn't going to vary some huge amount based upon signal strength. Basically, it works or it doesn't, with relatively little variance in speed. If your issue is slow connection speeds, external antennas won't help much either because the distance from the tower is the primary basis for determining what the allowable transmission speed shall be. Even if your device is attached to a focused antenna pointed squarely at the tower, theoretically allowing it to broadcast more strongly to that tower, your device isn't going to receive a significantly stronger signal.

Regarding broadband, cable isn't the only solution out there. If you're within range of LTE, I'd be shock and amazed if you were outside of range for a WiMax provider. Most rural locations near me are serviced by some sort of WiMax provider. You won't be getting 60Mbit from them, but it's not a bad service, and definitely cheaper than funky antennas that may or many not work for a phone. They often supply the equipment as well.
[Thunderbolt General] kierandill:
I wish I'd read that book by that wheelchair guy...
[Thunderbolt General] baronmxc:
Couldn't someone also build a private LTE network that runs off their home network? Or is this only limited to labs and government agencies?

Basically you connect to voice using Verizon's CDMA network, then use your private LTE for data since LTE is data only anyway.
[Thunderbolt General] ece4free:
I have suspicions that Verizon has disabled lower order modulation on it's LTE network since they can just switch people over to 3G to get similar speeds. That also makes their 4G network appear faster since they disable lower QoS tiers, so they can claim that they are the fastest. Quite clever if you ask me, since the lower QoS service wouldn't be much faster than 3G anyway.
[Thunderbolt General] stealthrt:
Alright thanks for taking the time to explain it to me, loonatik78 :)

David
[Thunderbolt General] mattmartin77:
i think that some antennas in phones are fractal based, and im pretty sure that the 4g antenna on the tbolt has two connections on the battery cover. fortunately, i have access to a laser cutter so i might make an external fractal 4g antenna, like this.
[Thunderbolt General] loonatik78:
If one desired, it's not at all impossible to implement an LTE pico-cell. That's actually part of the specification for LTE and has been used in GSM for a long time. That's typically how bad GSM coverage is resolved subterranean environments and sections of cities and buildings that have a small area of bad coverage. In theory, Verizon shouldn't have an issue with this and should permit making it an actual extension of their LTE network. Private companies have been doing that for years with GSM. In fact, AT&T is doing it with LTE right now by installing pico-cells in certain Apple stores.

But... then you're back to the uplink issue for your local base.

It might not be a bad idea to talk to Verizon about installing a pico-cell or micro-cell near you if there's more than just yourself who'd be served. Cells come in different sized and it could be set up to serve many more people rather easily if there's a demand for it.

It makes sense from a technical standpoint, too. On a packet based network, connections with lower latency tend to have higher priority. If you're connection drops below a point, it would make sense to kick you to CDMA where your latency might be lower and your connection priority higher, allowing for faster responses as well.

[EVO 4G General] derekwilkinson:
Really, getting an open-source OS to run on other platforms is easier than closed-source? der her
[EVO 4G General] fixxxer2008:
he still had to write a bootloader & drivers. the same could be done for us with the right motivation.
[EVO 4G General] cnstarz:
because writing a bootloader and drivers for an open source OS is exactly the same as doing it for a close-source OS.
[EVO 4G General] MichaelMcEntire:
Is WebOs not open source?
[EVO 4G General] CheesyNutz:
bit late to the party eeh
[EVO 4G General] jeeplj8:
When I switched from Pre to the Evo I thought Sprint would sell a lot of Evo's if they ran WebOS. I still cannot get my wife to do anything on my Evo, but she could use a Pre without problem.

Question is - has anyone actually ported WebOS to an Evo?
[EVO 4G General] dirkyd3rk:
Android being OPEN source makes it easier for devs to port on whatever phone they choose. We have android and we keep asking for CLOSED sourced ports. Why don't we get this yet? Are you surprised that android gets ported to so many other phones including the iphone lol?

To start off, I am following the "effen-manual" from the ace hack kit v10

phone is in debug and plugged in *charge only*

I keep getting held up on the model id check, i did some searching and found that this error is because it cannot connect to the sdcard? or that the goldcard creation didnt work...

anyhow i downloaded the goldcard helper app and even the simple goldcard program but nothing seems to work. the simple goldcard gives me the reverse of mmc2 but when i "load" the image it gives me a pop-up that if i "ok" through it throws a debug error on the program. I have tried getting an image of mmc0 & mmc2 *online documentation said use mmc2*

If i use the provided commands: hack-ace rev-cid

it returns Your reversed CID is: 00~28,-2~26,-4~24,-6~22,-8~20,-10~18,-12~16,-14~14,-16~12

,-18~10,-20~8,-22~6,-24~4,-26~2,-28~0,-30

again more garbage that it cant find the card

so now that i have the goldcard.img *stuck in the gcimg dir*

It looks like your gold card didnt get created correctly. Either go to the unlockr.com and search gold card. This is only to make a gold card not to root. they have a pretty good guide that works.

If that doesn't work then I would go to the irc chat channel from att1. Just look under his signature for the link. Tons of people there to help.

I hope you get rooted so you can enjoy the crazy good roms out there.

Had that issue when I first tried to run Hack Kit.

Fixed it by trying a different SD entirely, had an old Sandisk 2GB laying around.

Thats what i was coming to the conclusion of. I try to do indepth searching prior to asking but Im running on 26.4k dialup w00t! 3hrs of searching that could have been done in <20min ;-)

ohhh my! I didnt even try that... i was using the smallest *1gb* that i had but i do have a few others i could try. Local help too, im in Oneonta about 45min South of utica ;)

just curious, i havent seen any info on it but i shouldnt need to run that goldcard at all times would I?
[HTC Inspire 4G] nightborne:
You don't need to run the goldcard at all times. Mine is in a corner cabinet in my kitchen with a "do not touch" note on it for the kids (which means it is going to get touched eventually).

Once you create the goldcard, you can set it aside to use on another inspire or keep it safe in case you may need it again later. Some people say certain brands work better than others, but I spent $9 + change on a 2GB PNY branded one at Wal-Mart (right by the photo section) and it worked like a champ as a gold card.
[HTC Inspire 4G] Scott_S:
There's a couple of important, but often overlooked things that need to be done when making a goldcard.

It needs to be formatted FAT32, (and I chose 32kb allocation size). You also need to be sure you "safely remove hardware" from the computer OS whenever you switch USB modes (from charge only to disk drive, and vice-versa) even if you aren't actually removing the card from the phone. They get corrupted if you don't.

I had some POS 4gb, old-ass SD card laying around with a layer of dust on it, lol, that worked like a champ.

Now its back out of my phone re-gathering dust. :)
[HTC Inspire 4G] baggenismo:
I was able to make the goldcard after i switched to a different card. I had read your mentioned concerns prior so i did take care when switching modes and properly ejecting the device.

The issue was resolved with a different sdcard
[HTC Inspire 4G] Scott_S:
Glad you got it worked out.

My suggestions were mostly things to make sure of first, before going and buying a bunch of different new SD cards, as a lot of people have had to do.
[Captivate Q&A, Help & Troubleshooting] s13envy:
I just recieved a new captivate via a warranty issue. Welll this one came with froyo 2.2 already loaded. My last capitvate had serendipity 6.4 installed and had no problems with flashing that one. Since I go my new captivate I wanted to try flashing a new ROM of course. So I decided on continuum v4. Here is where my problem started I opened odin3 plugged the phone in while holding the volume buttons and sent it into download mode. then clicked start on odin and let it do its thing. it got where it said "removed" in the bottom part and "RESET" up in the green bar. after looking at my phone it was just a black screeen with the battery charging symbol loading. it would come up and then disappear and come back up. it kept doing this for a while. this is where i made the mistake....after waiting a while i unplugged the phone from the computer to see if it would even start or anything. Well of course it wont start at all. it gets stuck at the AT&T screen and wont go any further. I can't get it back into download mode and dont know what to do? is my phone a paperweight now? IF anyone can help, i would greatly appreciate it. Either via here or phone. I've got my sim card back in my backflip right now.

what do you guys think?
[Captivate Q&A, Help & Troubleshooting] kschumake83:

[Captivate Q&A, Help & Troubleshooting] mossination:
Can you get into recovery?

You could also buy a jig, but idk if im allowed to post the link so just pm me if you need it.

You could look up more than one way of getting into download mode. (there are several) Ill see if I can find them for you.
[Captivate Q&A, Help & Troubleshooting] s13envy:
i try holding the volume buttons and plugging the phone in which worked to get into download mode just before i ****ed it up. it doesn't work anymore it just loads the battery gauge and flashes on and off....if i hold the volume buttons and hit the power button the at&t screeen just flashes on and off infinitely
[Captivate Q&A, Help & Troubleshooting] mossination:
Try this, I found it by googling :cool:

I've had success with this method to get into Download Mode:

1. Remove battery, SIM and microSD from phone (if you have one)

2. Wait at least 10 seconds with the phone in this state

3. Plug your phone into your computer (this step has always been optional for me)

4. Hold Volume Up/Down, don't let go!

5. While holding both volume keys, insert the battery
[Captivate Q&A, Help & Troubleshooting] s13envy:

my question is what caused odin to fail on me? do i need a different version of odin to flash a captivate that came factory with froyo 2.2?
[Captivate Q&A, Help & Troubleshooting] mossination:
Lot of things could of happened, mainly because something might have happened to the wired connection between the pc and phone during the process. Im sorry I don't know the answer to the second question though. Maybe because the odin you were using was going back to stock "eclair" and not stock froyo?

[Captivate Q&A, Help & Troubleshooting] studacris:
Yes there are a few versions of odin but, either will work fine ... It's been reported that the one click will remove the 3 button fix in some phones with build numbers later than 1010, that info can be found under the battery btw, I've personally never had that problem, I flash and mod 3 captivates 1. Is a1010, 2. Are 1012's. All I've used is the one click version and they all still have 3 button combo.

There is an odin that flashes the 3 button combo while it flashes to stock, if you either never had it or have lost it ... Which I suggest you look for and use after you get jiggy with it so you'll have the combo for future use.
[Captivate Q&A, Help & Troubleshooting] s13envy:
after making the jig with the resistors and everything, instead of going to download mode it just tries to turn the phone on and flashes the at&t screen on and off repeatedly....not sure what to try now

Scratch that. Was doing it barehanded and it would just try turning it on. I used some gloves and got it into download mode.
