are cases necessary ? - Captivate General

I was messing around with my captivate and i was noticing it wasnt getting same amount of service that my old iphone 3g did. When i was in an area where service was quite sketchy , i would put it down and get two or three bars. When I picked it up in my hands it would drop for one bar or no service.
So the question is do we have to buy cases for these phones since service drops so much by having direct contact with the phone ?

no, cases are not necessary for reception.
If you are completely losing signal when its in your hands, you need to go to att and get a new sim card. If that doesnt work, have them replace your phone.
Note: if you are holding the phone by the bottom and losing bars but your signal is not dropping, this is perfectly normal. All phones do this to an extent since the antenna is located at the bottom. If you completely lose signal or drop calls because of it, you have a serious problem.

what i have noticed thats not just 3g reception its wifi too which is weird, i pick it up in my hand i lose a bar of wifi when i am in the same room as the cablemodem/router that doesnt seem right.
Usually when i pick up the phone it drops the three bars i hold it in my left hand usually. Another issue is i bought this phone thru amazon since it was 30 bucks cheaper for upgrade price, will att still allow for trade in or do i have to send back to amazon ?

I too have noticed this with my phone. Never really noticed until this iPhone 4 shiz came out. Guessing its par for the course.

areas where i used to get full bars i am not getting full anymore when i pick up the phone, it also happens with wifi which is really problematic.
Sitting in same room as router and cable modem and dropping below full wifi connection, and if i walk out of the room drops to one bar of wifi guess i will have to call att tomorrow and return my phone
Kind of off topic how thorougly do they check thier phones am i going to have to find an rom that has all the att bloatware stuff on it ?

This is a sad day really liked this phone , but appears i am going to have to return it , since this issue is a known issue so getting a new phone wont make these problems go away.
I was reading on another forum site that a lot of people having this same issue oh well i guess

wifi doesnt drop for me... thats really strange. in any case if you are only losing about 2 bars its normal and will happen with most phones. If you lose signal completly then its abnormal and ur phone/hardware is faulty.

yeah was reading about antennae issue on back part of phone where the battery cover is you cant touch it apparently. well i am going from 2 or 3 bars to zero bars pretty much.
An good example would be when i went into apple store which has 3g microcell tower in the store to hide the antennae problem with iphone 4 , i dont get full service and the iphones get full no matter how hard you grip them.
Going to give both samsung and att a call tomorrow morning to see what i can do i really dont think its fair to have to eat the upgrade and restock fee when phone cant perform normal functions

If you got the phone from amazon and are returning it, then it is free to return with no restocking fee. At least thats what they told me. All you gotta do is call the number for returns so u can get a return shipping label from them. Did you ask if you could exchange for another captivate at a local At&t Warranty Center?

I will be calling att and samsung tomorrow when i wake up to see what they have to say. As far as returning it to att, if its a known issue then an replacement phone will have the same possible issues.
So i did an little experiment to test 3g and wifi. I walked across the room, which has the modem and router, and stood by the door. got no 3g service in my hand, and the wifi dropped from full bars to just 1 bar of wifi in the same room.

I don't know what you guys are talking about. I can touch the phone any which way and the bar fluctuates by a single bar, if even that. I get more fluctuation walking around in my house then I do holding it. The only time I've ever noticed a significant drop in reception has been literally covering the phone front and back with both hands. Maybe you guys are just in poor reception areas. Before you completely discount the phone and send it back, instead of relying on the bars, look at the actual db signal in the settings.

I have looked at those i get an big fat zero. the other issue i have is my wifi goes from full to 1 bar by just moving to other side of the room thats not good at all.
I have been to areas of my town where i know there is full 3g service, and i get maybe two or three bars. i was thinking maybe an case would mask that particular issue since i am not directly touching the phone. The fact that i really like this phone i would just do the case thing if that were a solution

I will admit the area where i live doesn't have the best reception in the world, but when i place the phone on an table or sofa, i get -105 dbm and 4 asu. once i pick it up drops to 0 dbm and 0 asu quite odd.

Just to make sure, I removed my phone from it's case, and plastered my hands all over it. With a solid 3 bars, I touched sides, with two fingers all the way to a two handed deathgrip. Not only did I not get a degradation of bars, at one point I got a bar increase! I palmed the back, front, cradled it my hands, held it to my body. I didn't get any change in bars.
Maybe it's the band of cell phone signal in your area. I know that either the 1900mhz or 850mhz is better than the other in terms of penetrating power, so if your signal is going over the weaker one, that may be the issue.

I am just going to give samsung a call , when i actually use phone i am not touching the back of the phone. I have taken it into area where usually you should get full service and i dont get it if i hold it in my hand.
I also did an comparison with my old 3g iphone and the 3g was getting two to three more bars...
The other major issue is my wifi signal dropping from full to one bar in the same room of the router that shouldnt be happening

well its like i said, this signal issue that you few are having isnt that wide spread. go get a replacement sim, if that doesnt work then simply have ur carrier replace your phone. you should be within the 30 day trial period anyway... dont bother talking directly with samsung, getting a phone replacement from att would be quicker.

well the only issue with returning the phone i dindt buy it directly from att , got it thru amazon so returning to get a new one may be a bit problematic i think.

The iPhone's issue is different - it has an external antenna, and one finger in the wrong place rendered no signal - one finger bridging the gap between antennas - creating an electrical conductive circuit.
The Captivate (and all other phones) have internal antennas covered with plastic (the phone's case) - so the antenna is already covered.
Apple tried to deflect criticism by talking about "The grip of death" killing signal on other phones. While this is true, it is not what plagues the iphone - although it can. All phones will show signal drop if you wrap your hand (or some other signal blocking material) around the phone.
The Problem with trying to measure the signal drop, is that signal bars are not very accurate - you need to be in the phone menus where it shows you actual signal strength in DB - I don't think you will get this for WiFi though. Then of course there are all kinds of external interference issues - Microwave ovens, cordless phones, etc.
So, unless you measure this stuff in a controlled environment, like consumer reports did, where you can control the transmitter and all eliminate all external influences, then most observations are not including all environmental factors.
My phone works great, regardless of what the bars say.

well i have seen my phones service go from -105 dbm 4 asu to nothing when i picked up the phone. and then i would get the nice blue circle with line thru it.
I did an speed test also with phone while holding it and when putting it on an table , the times i would actually get no bars on my phone while holding i would get 1/3 the dl speed of when it was sitting on a table.
I will have to wait till tues to get an replacement phone and hopefully i wont have the same issues

so are you getting the replacement from att or amazon?

Deathgrip

If I hold my phone normally (near the bottom) my signal plummets, is this normal or do I have a lemon?? It is really worrying me, if I grab it near the bottom I go from 3 to 0 but still have service but I am still without bays and my data slows. I don't know if this is normal and I should just accept it or if I should go exchange it.

I haven't been able to produce the "death grip" effect even when I have tried to.
Mine does the same in my house with a pretty weak signal. However, unlike my iPhone 4 (I am a happy convert to android now) which dropped calls and data went to 0, the Captivate seems to keep the connection. Even with zero bars, I get decent data speeds and people say I am loud and clear on the phone.
I wouldn't stress over it. The antenna has to be located somewhere in these phones, and yeah, covering it completely will cause a signal drop. Just be happy the antenna is on the inside and you can't short it with your skin
I get the same thing, but I think where I work is a dead zone, because my old phone had problems holding a signal also. I'll do some more testing when I'm out of here
OK, I will do more testing and make a final decision next week since I am going out of state to a place I know has good coverage and if I get bad signal there it is probably my phone and not coverage area.

I have to completely cover the metal back to drop a couple of bars. Even then, it still performs about the same in speedtests.
It is not the metal back you need to cover on my phone but instead the plastic below the back...

Tried it this way as well and the results were even closer together.
It's the way Samsung is programming the bars. They underestimate signal strength believe it or not.. it's not like the iPhone where it gives you this crazy readout (before 4.0.1).. it's still wrong, but in the best way possible.
Dropping calls like crazy with Captivate
I was just on a very important call about a new job and my captivate dropped the call 4 times within 15 minutes. I was holding the phone only on the outside. I was not touching the bottom or the back of the phone. How frustrating. It even drops calls when I am using my headset. Just dropping all the time. Any suggestions?
I can get the bars to drop one or two when I hold the phone at the bottom, however (and this is a BIG however!) even with 0 bars, I was just able to make a phone call, and while the signal bounced from 2 to 1 to 0 to 1 bars, the call didn't drop or even so much as hiccup.
As heygrl said, it seems however Samsung calculates their bars, the phones are displaying a lot less signal strength than they actually have, which is a good thing in my book. It's a nice surprise to look at your screen, see 0 bars, desperately try to make a call anyway, and have it go through!

Sounds like the AT&T network to me.
Yeah you can see how Samsung reinterprets the phones recieved signal strength under the Service Menu. I also suspected that the reason why we only see -81dBm max and not -51dBm like the Captivate is because Samsung didn't completely readjust the scaling and just cut off one visible bar. Under the Service Menu (Antenna/ADC or something of the sort) you can see where it says "Antenna bar: 5" when we clearly only have 4. The same goes for actual signal strength, you can see a very usable 10 RSSI but Samsung designed the bars to show that as "0" instead of 1.
I do notice that when I'm in areas that are 1-2 bars, giving the phone the deathgrip does kill the signal totally. But when I'm out in full service I can hold it any way and no problem.

[Q] found a serious flaw with radio hardware and shipped ROM downloading consistency!

Hi all, please welcome me whom had bought the Optimus 3d just 2 days ago. I love this phone. Please do let me welcome you all to talk about a flaw, which I've found out right away with the new phone since 2 days ago! I've been with some others Android phones, so, I should say I've had good experience with Androids.
I realized that Optimus 3D has some kinda hardware Radio receiver flaw (I really don't know what should I really call it) similar to the famous iPhone 4 dilemma in the beginning. I found out that the "Radio receiver" is located somewhere at the bottom of the phone, where our hands most often holding the phone with. The hand will block out the signals and the signal bar will be reduced by a lot as much as to zero (if the signal strength itself is not strong in the 1st place!) Try find this yourself, have some experience by holding the phone at the bottom and let go and holding the phone and again let go, keep trying this you should see the signal strength that will drop and rise and drop and rise again. Or is this only my phone? But I've never experience this phenomenal with other Android phones!
Also, I don't know this has the directly link to the downloading issue or whenever browsing nets, the network data will drop very very often. I hardly got successful downloads from the market without few retries. Thank god at least at the moment I can temporarily fix it by turning off and on again with the data enabling shortcut in the pull down menu.
Please help me here and advice! Very much appreciated!
Since the famous iPhone 4 drama for a lot of phones these stories pop up once in a while. I know lots of people furiously believed the Samsung Galaxy S had the exact same problem but after a week or so nobody ever talked about it anymore.
I myself have absolutely no problem whatsoever with the signal, not even when I completely cover the entire phone with my hands leaving just a small spot to read the signal it never drops, not by one bar. I've never had a single download dropped with either 3G or wifi and I've downloaded my share of stuff from the market and other places.
I've tested this with my T-Mobile simcard (which has pretty horrible coverage here) and with my Vodafone simcard (which has great reception) and with both simcards the signal strength stays exactly the same according to the bars. Even when I go to the settings the dBm and asu values stay exactly the same, no matter how long and how bad I cover the phone.
So far you're the first and only person I've read about having these issues so I think it just could be an isolated incident, although that would be bad for you as that would mean you could have a defective phone
This problem is not something new and is not related with O3D.
All the phones have the same issue.
It is normal that if put your hand on the antenna the reception will drop.
The radio waves just work like this.
However the atenuation from your hand is most accentuated on higher frequencies like 2100Mhz.
On every phone even on the oldest phone with external antenna you will meet this phenomenon.
The difference between 4 bars and 1 bar is only around 10dBm which really isnt that massive a drop at all. Now that you've pointed this out i do see that the signal strength varies a little depending on how you hold the phone but its not enough to panic about i don't think. The iphone 4 problem was significantly greater in that the iss was that a user's hand would electeically short the mobile network antenna to the bluetooth and wifi antenna causing a total loss of signal. While 10dBm or so is a definite dip in signal strength, it's an acceptable level of attenuation and i dont see it causing any real world day to day network problems that you wouldn't experience with any other high end smartphone.
My workplace is in a giant tin hut of an industrial unit (read: faraday cage) and today while i had this phone there for the first time i saw no noticeable network coverage problems. The behaviour was as far as i can tell exactly tue same as my motorola milestone from which i upgraded.

As stated all phones can lose a bit of the reception when it's in your hand depending on how you hold it, the reason Iphone4 was such a big deal was that it was extremly sensitive when it came to left-handed people and they had a real problem with their antenna being totally blocked when holding the phone normally when speaking in it.
Later on media and uninformed people started fueling the flames as soon as they saw a bar drop when picking up the phone, radio waves are not magical rays or tachyons that can move though matter without interacting with it.
thanks for all the replies. Believe me or not, this is the 1st phone I realize this issue and it is so obvious, the bad news is, it is really bad for me that the antenna is located at the bottom, probably most others phones I've owned were at the top as a result i didn't got any problem before.
And another issue, I'm pretty stucked with the shipped rom now, really hope to see custom roms soon. I'm at the moment totally freak out with the inconsistent of data and the wifi, it keeps failing me, this really freak me off, what the hell is happening to me with this phone! I've never ever got any dropped data or wifi connections before. Arggghhhh!!!!!!!!!!!
I have no signal drop out no matter what hand positioning i use..
I'm in a very poor reception area. I do notice hand over phone a drop from 1 bar to none. Still not a red cross to indicate no signal but a drop of 1 bar all the same.
Just tested it.
Signal drops from 4 bars to 3 (1-2 in awkward positions) when hand-held. Not an real-life-usage impact though...
Thanks for all the test replies to support my findings. OK, now, I've realized that the hand holding issue has no direct impact to data drops. And the data drop is entirely due to the time issue which it does not lock down the data connection when swithcing data modes. And at the moment it can beasily over come to turn off with the data button in the pull down menu. I'm not sure though when in the situation when the signal strenght was so low, by holding with hands will give an direct effect of data drop or not. Will observe that

[Q] Struggling with Reception.

I have not done anything software wise to my phone, its still a factory rom and radio for ATT... now my issue is I'm struggling all the time with reception with this phone. I don't remember it being this bad when I first got it and now its just becoming a huge annoyance.
I'll have phone calls breaking up with a display showing 3-4 bars of service and also having troubles sending txt messages quite often.
I'm in an area that is labeled as HPSA coverage area and my "voice" coverage map for my area is not bad at all... for example where I work is listed as "BEST" coverage and if I walk outside I'll have 2 maybe 3 bars of service.
There is nothing visibly wrong with my antenna/sim cover but should I attempt to replace it and see if that could be causing the problem?
There is nothing out there on the web for improving reception on a Inspire 4G phone and there is now way to shut off the HPSA and revert to 3G, but at the same time I really should have to since my whole state is covered with blue for HPSA coverage.
Any input on things that I can try would be great.
Thanks.

hpsa is basically 3g just optimized packet transmission. You can change your phone to run on edge network (which is why i personally do because then i can get a ton more battery life) Also it doesnt matter what your area is 'claimed' to be for coverage, there are a ton of outside factors that influence your signal. What you can do is take the bottom cover off and clean the gold contacts on the phone itself with alcohol and using something metal, lightly scrape the cover-side contacts to shine up the metal (but not removing the material itself)
Well aware of all the things you mentioned, as well as I've tried cleaning the contacts multiple times. Used an eraser on the cover side to polish the contacts and got no improvement with signal. I also can not find any way to shut off HPSA or 3G on this phone... and I've read that with the AT&T Inspire it's not possible. I'd love to switch to Edge when at work because as you said it would extend battery life immensely.
But I guess the real issue is I never had these problems before with any of my phones or this one at first, granted I have some dead spots which I'm well aware of and accept since I do live in the hilly north east corner but to have this phone degrade with signal over the time I've had it just seems a bit odd.
I was just wondering if anyone else has experienced signal loss with an Inspire 4G over the life of the phone without having any physical damage done to it. As well as having much less signal strength in comparison to other phone models.
I'm contemplating getting a new phone but I want to ensure that whatever I get would have better reception. I'm close to my 2yr resign IIRC and when I do find out that date I will probably replace this.
Its just the whole antenna on the Inspire seems to be lacking and very small in my mind, and placed very badly.
*#*#4636#*#* dial this and get into your config menu. change network type to edge/gsm i think it is? been a while since ive used stock ui
fyi the antenna is supposed to be small as it has to be designed to receive certain frequency. antenna length has to do with what signal it is using. bigger is not better
theres an app on market called 2g/3g toggle. it will put a button on your screen to take u to that menu screen instantly
That worked but which network do you switch to, It was on WCDMA Preferred
Also that app only brings me to the network settings in the phone, not to this menu.
I selected "GSM Only" for now to see what it does.

Thanks ✟
Moving to Q&A
This is a matter of interest to me as well. I've been looking at some videos for "fixing" the reception of other phone models by finding the gold contacts and extending the "antenna" by attaching a piece of aluminum foil to the antenna points. Now with the Inspire, the contact points are in the battery cover, but you'd have to open the unit itself to see anything more than that. I'm thinking that some reception problems may be due to worn contacts. I'd be interested in what kind of substance would be appropriate for "restoring" the contacts. Also I'd be interested if someone *has* opened up the unit and "extended" the antenna with something like aluminum foil.
From what I could gather the cell antenna is actually on the bottom cover for the SIM an SD cards. All I did was use an eraser on the contacts to clean them up and yes I did try to lay down foil to extend the antenna but from what I have read regarding radio's and such the antenna size and shape is specific to the signal its trying to pick up, so that could either work great or fail completely when you try to extend it. It did not help for my situation at all.
Lately the phone will not send txt's with one bar of HPSA or just on Edge which makes no sense to me and also I'm quite often only getting one bar unless I can see a tower right next to me which is a bit sad and I do not remember having this issue before.
Also changing the preferred network did not prevent it from using or wanting to go to HPSA while I'm at work. It would operate the same as before. Its impossible to get this phone to stick on regular 3g which I feel I have better coverage of that network in my area.
I'm contemplating rooting the phone and trying some different radio's on it to see if that will help me at all.
I never had this many signal issues with my 3Gs and I'm contemplating going back to that phone until I can upgrade again since this is just so aggravating... More so than having to have the same txt sounds as everyone else with an iPhone.
I think it us just AT&T having problems on their side. Some days I gave great reception, and others it struggles to maintain one bar all day. Its getting very annoying for me, and I probably won't be with them for much longer...Verizon looks much better right now.

[Q] Signal strength 3G and Wifi down if you cover the back?

Hi,
Some users on a Dutch forum reported a loss of signal strength (both Wifi and phone) when the back of the Moto G is covered by your hand. I checked and I can repeat the problem. If I cover the lower half of the back, my carrier signal goes down by two bars. When you cover the upper half, the Wifi signal drops substantially.
To test if this was a real loss of signal instead of an issue with extremely sensitive bar display, I have installed Wifi Analyzer. It shows a drop of 5 - 10 dB on the Wifi signal so its a real issue.
Do others have the same problem or are there some faulty units around?
I cannot reproduce this. XT1032 8GB retail GB version.
16GB UK - I can get WiFi to drop by covering the back.
Mobile signal does not drop though.
Doesn't worry me as I don't press my hand on the back when holding the phone.
I can also get the signal to drop wrap my hand around my routers antenna.
I would think it's quite normal for a signal to drop if you cover the antenna or receiver. The phone has to have the receiver somewhere and wherever they put it you will be able to cover it if you try hard enough.

Remember the 'you're holding it wrong' defense of Steve Jobs when the iPhone dropped its signal?
I don't need to press, just by holding the phone in a natural way to take a call the signal will drop. And like I said covering only half of the back is sufficient.
That Debaj can't reproduce it, suggest it's not in all Moto G's
Moto G 8GB German, left-handed (in case it makes a difference) and it occurs most often when the signal is at 4 instead of 5 bars to begin with.

Mine does the same to an extent but not nearly as bad as my old phone. Two bars missing sounds quite serious, though. Have you tried taking the rear cover off and checking to see what it does?
Wifi signal drops 1 bar (from 4 to 3) when covering top of the back. Not a big deal to me
Mobile signal doesn't drop when covering the bottom of the back.
Moto G 8GB, British retail version running US global 4.4.2
EDIT: Holding the phone in the left hand drops the signal by about 5dBm. Holding the phone in the right hand leads to no loss in signal. The only way I can get my Moto G to lose some signal (from 4 bars to 3) is to hold the phone in my left hand AND cover the bottom bezel with the right hand. It drops about 15dBm.
Thanks chowy993, scott_doyland, WabbitKiLR and Debaj for your feedback.
I guess there is something wrong with my Moto as I have an 8-15 dBm drop on the carrier signal just by holding my hand it in the normal 'telephone position' (but not next to my head). I measured it with an app called Network Signal. It drops into the red zone at over a -100 dBm so its a serious problem which will cost me battery life and loss of connectivity in some places .
I tried this with my wifes Moto G and the wifi drops one bar if I put my hand over the back. The mobile signal remains the same. Then I tried it with my Galaxy S3 and got exactly the same result.
I posted a thread about this a short while ago on the 31st December: http://forum.xda-developers.com/showthread.php?t=2592673
I can confirm I have this issue too! I cannot do any video or voice calls over WiFi if I hold my phone in my hand. The connection repeatedly drops until I put the phone down.
As soon as I hold it, I completely lose all WiFi signal (I have full bars at the time), and can also lose all 2G signal too (from full bars to Emergency Calls Only). My only solution was to simply leave the phone on a surface.
Mine is being sent in for a repair tomorrow for this reason. But sadly it appears even if the phone is replaced/repaired, that this is simply a issue with the Moto G in general?!
Never experienced such poor problems like this on a phone before.
I have the exact same problem on my 8 retail UK version I posted about this here http://forum.xda-developers.com/showthread.php?t=2588286
And people were saying its the way I was holding my device. It isn't I can completely make my device lose signal just by being in a call. And cover the the bottom of device. It seems like there is a bad batch and Motorola needs to sort it. I'm on my 3rd device now and its still doing it. Gutted really because its a brilliant device. It seems to be the 8gig version having these problems I got told.

Cannot reproduce the issue at all, neither mobile nor wi-fi drops even with the back fully covered by both my hands. Held it like that for five minutes and no sign of it.

Count yourself as a lucky then I think I'm going to replace my 8gig for the 16gig.

UK 16 gig model and I can get my WiFi to drop by one bar but mobile signal is unchanged no matter how I hold the handset. Bad news for u mate, sorry.
I looked into this problem.
Believe it or not, it seems to be down to the use of spray deoderant.
Most spray on deoderant using aluminium oxide. When it get's on your hands, and you hold the phone, the light metal coating causes a charge differential with the phone's antenna (basically your hand and the phone act as a single film capacitor).
This is different from the issue with the iphone, this was because the metal bezel of the phone actually changed resistivity when held directly with the hand, effectively changing the length, and therefore effectiveness of the iphones antenna.
I suggest washing your hands thoroughly. You can also use a multimeter on your hand, set to milli Ohms to see if you have an unusual resistivity (probably due to aluminium oxide).
Roll on deoderant is another good option.. Or just be smelly of course. I never wash, shower or using any cleaning products and my phone has perfect signal all the time.
mranonymous1 and maccboy2010 can you check if it's identical to my problem: holding the lower end is a drop in carrier signal, upper half of the phone: wifi drop ?

I no longer have my phone as it's in for repair. I can tell you though that for the week or so of use that it was awful. Mine was extremely sensitive that a video/voice call over WiFi would instantly end the second I even went near the phone/picked it up.
It was the WiFi dropping that was more of the issue for me than mobile network signal (I struggle to get 2G signal anyway where I live). But I could easily lose all mobile network signal from holding normally too.
Ok, I checked again and the problem only occurs if the signal level is not that good to begin with. It then drops enormously making calls impossible. Handsfree calling in the same circumstances is no problem.
When I am at a place with a strong carrier signal my hand hardly influences the level. So it's sort of a worst case scenario but it explains why others don't notice the drop.

Yes mine is the same as yours if I hold a the bottom signal drastically drops.

I can confirm covering the bottom drops my signal.

Also happens with my moto g. Covering the top indeed affects wifi and the bottom affects signal.

Free Tmobile indoor signal booster for 4G/LTE

Anyone have this?
It does seem to work but the 4G LTE is too weak indoors. It does pick up plain 4G (HSPA+) and the phone is much better than EDGE for sure!
I'm pretty sure if I elevate the receiver higher (we have towers outside LOL) I can probably get 2 bars of LTE. If it works I'll mount the receiver in a waterproof PVC enclosure and use a solar panel, battery pack and switching power supply to keep it happy. Had a direct lightning strike to two towers last summer that scared the $hit out of us so no wires!
My concern is on hot days in direct sun it could get too warm. If I can find a actively cooled PTZ case large enough to fit it that would work. Probably have to put up a 25W panel LOL!
I have the Tmobile Cellspot router.. they expect you to use it for wifi calling. I love it
I cant comment on the booster through you may be referring to.
I used to have this and it didn't make much of a difference, and was kind of a hassle. Then I got the s6 with wifi calling, so I ended up returning the signal bosster.
I have it. It's okay, but the range is lacking, imo
How do you get these devices for free?

If you have tmobile, go into the store and inquire about it. Theyll ask you questions to see which you "qualify" for
What this device has is two parts. The "window" unit and the booster. Idea is to put the window unit in an area of your house that gets the best 4G (HSPA/+) and /or LTE. They claim one bar on the display is OK.
The booster unit gets placed far away from the window unit. It has an LED that goes from 1 to 9. If the units are too close together the number will be very low. What you're supposed to do to get the best results is to have the highest signal showing on the window unit and the highest number on the booster. But be careful as if the booster is too far away it will flash red LEDs that indicate you must move it closer to the window unit. The higher the number means you will have better coverage. The higher the number of bars on the window unit means better results as well.
This is good say if you get two or three bars outside but in a basement you get next to nothing.
This will allow you to use your phone in an interior room on a lower level where otherwise it wouldn't work.
It's also important to use the device only at a location where it's registered. This is to make sure 911 services can locate you accurately.
