I recently discovered the chrome inlay surrounding the camera pops off and under it is a port for an external antenna. I go camping every now and then at a place not too far from home where unless I'm in a field, the service isn't strong enough to hold a call. Though texting is fairly reliable. Would an External Antenna be substantially helpful? Would it boost my Data signal as well? It would be great to use the Dun hack when camping.
I've been trying to find a decent external antenna which I can use on my Env Touch for those times when I have a faint signal but not enough to actually hold a call or send a text. I've been looking on eBay and other places but its hard to find one with a direct CRC9 connector. Any recommendations?
Anyone know is it possible to connect an external antenna to the CK-100 Car Kit? and if so, is there a socket on the unit into which it can be plugged?
I need an external antenna to boost my signal in my basement, I was messing around i discovered this antenna attachment under a black sticker. I don't know whats the connector for this called, any help?P.S samsung doesn't mention any external connector in the manual
Yes, I know there are plenty of threads on this already, I just wanna do a quick straw poll to get a sense of whether this is a design or manufacturing/batch fault.I can replicate the left handed signal drop issue on the iPhone 4, and disabling 3g does help alleviate the issue. I'm in the UK on o2, so far no dropped calls, although I don't ever recall having dropped calls at all.Given how this seems to be a pretty hardware serious fault, I may march into the Apple store and DEMAND a free bumper in the interim.
I've had the iP4 since the launch day and yes I have seen the bars drop but haven't dropped a darn call yet. I'm on the phone for the better part of each day and I, like Mr. Jobs, see this as a NON ISSUE. It's just like the old story "Dr. my arm hurts when I position it like this" Dr: "Well don't do that" " Honestly, the news, media and Apple haters have taken this story and misconstrued the hell out of it. Whenever any company sells a million of anything, there are going to be some issues with a small % of the devices. That's a given. The problem nowadays, is that the first "I want some media love-whore attention jerk" will begin to whine, tip news outlets and complain on every message bored around. I've TRIED to drop a call by using a Samurai Death Grip and it just wouldn't happen. Yes, the bars fall but it's not hurting reception or the phones performance. Anywho, to those who have been weary about picking up and iP4 because of this nonsense please don't hesitate it's seriously not that bad.
Just curious, if there are any major problems people are having with their iPhones at all? I'm tempted to get one but what's holding me back is the antenna issue right now, but I was also curious if there were any other problems people were having?
How the heck do I change the name from att to my name..The att logo next to the antenna.And yes I am a noob.Laugh it up.but I did get my phone unlock from att...hahahah....I hope every one has there phone unlocked.O and by the way My phone is a E71x and again my cell is unlocked...
I have a Nokia 5800. I just upgraded today to the last version of the phone and maps. I have installed the ovi suite. All latest versions. From the Ovi I got the maps of Germany. Going to the Maps application I can see the maps, zooming in, out... looking for a location.
I want to work offline so in the options i have chosen only "Integrated GSP" (No a-GPS). But the problem I'm having is that the phone doesn't connect via the GPS antenna, the satellite icon is crossed out, the first bar of the signal yellow blinking and if i want to make a route to any location it says "waiting for GPS". I've been searching in the forum but i couldn't go further this point. It seems as i have the satellite signal deactivated.
So since I have been having the reception antenna issues I thought I would make an appointment and stop in to the Apple store today. I told the guy all my issues and he said we can either replace it or give you a bumper and see if it helps. I thought it would be a good idea if I started fresh with a new phone. He went in back and came out with a box that was NOT the nice small iPhone 4 retail box.
It was plastic looking like one of those small hardware screwdriver boxes with all the little bits. He opened the box and in it was an iPhone 4 surrounded in black foam and the phone was wrapped in a little bag. My first thought was this has to be a refurbished or one someone brought back that was having a different problem. He said "How could it be refurbished? The phone just came out." I didn't believe him cause he has a odd smirk on his face when he said it.....
Do you think that Apple made a calculated risk with it's new antenna design? Let's take the 3G/3GS.....the antenna is on the inside of the phone behind essentially an outer plastic shell. So a naked iPhone 3GS the antenna signal goes through 1 layer (the plastic back).
Do you think Apple had enough research and statistics to show that the majority of users put an iPhone in some sort of case, whether that case is plastic or silicone? So now on a 3GS, the antenna has to go through the plastic back, then a plastic/silicone case....now it's going through 2 layers. Do you think they determined that this combo caused a lower/weaker signal?
Now the iPhone 4....antenna on the outside. Do you think Apple took a calculated risk in knowing that most people put it in a case anyway (heck even Steve in one of his emails suggested using a case) and the fact they came out with the bumper....that they knew since most people would put a case on it....that the antenna being on the outside would provide a stronger signal?
Yes, the people who choose to go caseless with their phones are more easily affected by the issue, but since that may be the minority of users, Apple is ok with saying "Hold it differently"? We all know Apple does things based on what they "think" the majority of users will do....ie: no firewire on low end Macbooks.I don't know anything about antenna signals, so I'm just guessing here.....but if an antenna's signal is degraded behind each layer of plastic etc, then by moving the antenna outside, Apple is giving it a better chance at getting a stronger signal, even though there is a side effect of direct contact with skin that can cause the signal to degrade significantly.
Tests I would like to see are the difference in signal strength in a 3GS with the back on and the back off.
I've been looking around and I'm not really finding too much information.First of all, I need to know the dB Gain of the internal 1900MHz antenna, which is just a piece of aluminum curved around a few times. Second of all, I need to know what the external antenna plug is called. It kind of looks like MMCX, or MCX, or maybe MC-Card... Although I can not be sure unless I order these connectors to test out.
I know I can get the Wilson external antenna adapter but I think it is too big for what I need. I'd like to get something I can mount on the board permanently and just add an external 3-7 dB Gain omni-directional antenna for travel usage, or connect a 15+ dB Gain outdoor directional antenna when being used inside. Pictures below are 1, antenna connectors, and 2, screw on SMA 3-7 dB Gain antenna for use while traveling. Added a 2 pics of the jack on the Mogul for the external antenna, first is not a good quality pic though.
How good is the wifi antenna on the Eris? Comparable to a decent laptop?I've never had a phone with wifi before but I would want a phone that can get reception where my laptop does. Sometimes I use these devices pretty far from the AP with low signal strength.
Where is the phone antenna of the Xperia Ray located? My best guess is that it is located below the battery (not under), beside the speaker at the back.
The antenna in the E71 model is situated in the bottom of the keypad, next to the microphone. I generally handle the phone in the left hand while I work on the other things with the right hand. Actually, except while typing something on the phone, most of the time it's in my left hand, with the antenna behind the palm (or the palm behind the antenna). Do you think it causes some health or reception issues? The SAR emission from this model is already more than double of most other models.
So far, I've not noticed the signal strength dwindling with my normal handling of the phone. The call quality is the best I've ever experienced in any other brand. The voice is clear, crisp, and very real. My concern is, then, with the effect of constantly using the phone for web browsing or for the calls on the human body. Will it adversely impact me or my hand?
Don't you think the antennas should always be on the top (but on the backside to reduce their impact near the head while talking)? Why do people come up with the new ideas that make little sense? And then, how many of us get to know where the antenna in any new phone model is? If the position is a fixed one, at least everyone will know how to hold the phone right.
I've got a N97 mini and notice that I keep losing the signal. I can be sat there, the phone won't move and yet I'll go from 4 bars to virtually one/none at all. I had a similar problem with another N series and apparently it was to do with the internal antenna.......I'm sure its not the network as was on 3 before changing over to O2 and had same issues ! Also does anyone know if the CR 116 will fit the mini as well ?
a few weeks ago i saw somebody who got a free bumber by complaining to apple. Supposedly it solves the problem. I went to the apple store and what they tell me is ridiculous. buy a bumper im NOT going to buy a piece of plastic that cost 60 cents to make in china. FU&K that. or Return the iphone. Thats out of the damn question i love the damn phone i spend hours waiting in line. So if anyone can help me find that free bumper people have been getting for the issue that would be great. Thanks for the help and sorry for the rant
For those who have the Lumia 950XL, can you comment on signal strength as it relates to the Dual Antenna feature that was touted when the device was first announced? I kept hearing about this Adaptive Antenna Technology that blends signal from two antennas and that the 950XL utilized this technology. Was it just another one of those hype vehicles to sell units or does the Lumia 950XL actually get better signal/reception due to this adaptive antenna feature?
WiFi antenna location on iPad2 and iPhone4? Somebody says the iPad antenna has more gain than the iPhone one but according to my checks when holding the devices it is not true.
I got my sprint curve 8530 last thursday, and so far haven't been having a good experience.
I have horrible battery life with the device. With brightness at 10 percent, ten second backlight, locking the phone when not in use, having wifi and bluetooth off when not in use, and phone off or antenna off when in low service (about four hours), I am lucky to get through the day with a little bit of heavy use (web browsing). I have a few minutes of calls, and mainly texting and web browsing with some email. I expected better battery life out of a blackberry!
The reception on my phone is bad. I have five bars of sprint coverage at my house, but when I pick up the phone and start using it the coverage drops to two bars, zero bars, searching, and can't keep a signal. With one bar of service my phone won't send messages, and then I will lose the bar where my old phone would get one bar solid, sometimes two bars.
I'm an engineer, and a collegue of mine has a friend (tedious link I know!) who works for a mobile phone manufacturer as an engineer. His take on the whole atenna issue is the following:
1. Sticking your hand over the join between the atennae short circuits them (we all knew this!)
2. The short circuit causes the two small antennae to form one much larger one (obvious I know...bear with me!)
3. This larger antenna has a different frequency to the small one.
4. The phone detects this and switches between frequencies.
Sounds simple in practice, but apparently it takes an age for the software to switch between the two frequencies. My guess would be this is to prevent the phone from hunting between signals. This could indeed be what Apple were talking about when they mentioned that the new phone placed lower demands on the network.
For the sake of making things easy to understand, have a read through the two artciles on Wikipedia and HowStuffWorks:
http://en.wikipedia.org/wiki/Cell_site
[url]
Basically, a Cell Tower has a finite number of frequencies it can use and assigns your phone to one of these frequencies. As you move around however, you'll be assigned different frequencies on different towers depending on what's available. As you can imagine, if a phone is super sensitive to variations in signal quality, it can reach a point where it jumps continuously between cell towers, placing high demand on all the switching hardware in the network. In reality, the user wouldn't notice any change in call quality if it stayed on one tower. By placing a delay in the frequency switching on the phone, your call will no longer be shuffled around towers constantly and will instead stick to one cell tower for longer, reducing the amount of juggling the network servers have to do and hence reducing dropped calls.
Here in lies the problem. When you change the length of the antenna on the phone, you cut out it's ability to see one segment of frequencies. The phone then starts looking for another available frequency. This now takes forever. Although the frequency may well be avaible, by the time it's found it, the call has been dropped as the slightly weaking signal it is expecting as you move away from the original tower has completely dissapeared.
The design of the antenna is undoubtably a fundamental design issue, which has somehow been overlooked or ignored. Let's not get into the politics of that here. What this does highlight however is that, if the delay between frequency switching is removed, reduced or in some way made smarter, the switch will be so quick, it won't have any noticeable effect on your call as it will just be another frequency switch similar to that between a towers.
So i got my phone today from att and of course it has the issue ( not complaining ill deal haha cause its awesome) anyway called apple to see whats up and they told me there will be a update soon blah blah and until then i should put a piece of scotch tape over the antenna and they would fix it for now. Sure enough it did and it hasn't happened since. Just thought id pass this along for those who might wanna try it out.
My iPhone 4 has been really buggy with the data connections on 3G. I run Speed-Test.Net on it and it barely registers sometimes.....I have to turn it off, reset the network, put it in airplane mode, and then once in a while it will kick in with decent 3G speeds. I thought I was going mad or just imagining this due to all the talk about the antenna. Then I did a test beside someone else's 3GS and I knew there was a problem. I called ATT and got the tier 1 tech. They tried all the stuff I tried above and the Speed-Test and the latency test were all still terrible numbers.
They made me an appointment at the Apple store for 5:30 PM today. I show up and I don't even tell the genius my problem and she is like they are working on the 4.0.1 firmware fix. She did not even look at my phone. The problem is apparently very widespread, and really has nothing to do with the antenna, and that the shorting is just a symptom of the software glitches and the real issue was the switch from the normal sim to the micro sim. Apparently the software was written for the regular sim, and then they made an 11th hour switch to the micro sim, and it was never properly tested. She also said that all the Apple store employees that have the iPhone 4 have the same issues and they are all bummed............
Time to buy a new one.The amorphous metal alloys developed by Liquidmetal Technologies may be used in the design and development of Apple’s next generation wireless antenna, according to Liquidmetal founder Dr. Atakan Peker. In an interview with Cult of Mac, Dr. Peker notes that the properties of Liquidmetal make is an excellent substrate for usage as an antenna and could be one of many reasons Apple signed a broad licensing deal with the California company.Described as a metallic glass, the various alloys used in Liquidmetal offer a high strength to weight ratio, high wear resistance, and a low softening temperature that allows it to be molded into complex shapes and designs. Liquidmetal technology is already used in a wide variety of consumer products including sports equipment like golf clubs and skis, jewelry, and in electronics where it makes its appearance in the casings of USB thumb drives, MP3 players, and mobile phones. It is also used in the antenna of the Verizon USB727 wireless modem, which is known for its excellent reception. Surprise, surprise, Apple already uses this novel technology in its newly released Magic Trackpad.URL...
I m having an factory unlocked iphone 4S and i starts losing my signal bars when i take out my phone from case (bumper) and sometimes in case also when i hold my phone with some force its again starts lossing its signal bar Is any 1 having this problem ..?i m having iOS 5.1..!
I was testing the Ovi Maps and found that the horizontal screen (Landscape) is better to navigate than the vertical (Portrait) position What is intriguing me is that my 5230 only switch from portrait to Landscape when turned to the left, and in this case the GPS antenna would be located in lower place of the unit, not at the top, where it should be. Question: Wy 5230 do change the screen from portrait to Landscape only when switching to the left and not to the right? How I can make this to works correctly, so that the GPS antenna is looking to the sky and not to the floor in the landscape position?
