Full FCC Wi-Fi report - Asus Eee Pad Transformer Prime

The FCC has a full, 81 page report on the Transformer Prime's WiFi performance. I'm not skilled enough to decipher the results enough to interpret them intelligently, but I'm sure someone here is.
The report can be found here:
http://transition.fcc.gov/oet/ea/fccid/
Grantee Code: MSQ
Product Code: TF201
click "detail" on the first row, then "RF report" at the bottom of the list.
It's got all kinds of dBm tests and graphs.

Looks like WiFi antennae have been designed with vertical and horizontal orientation: http://forum.xda-developers.com/showpost.php?p=20935062&postcount=15

GPS accuracy?

I'm finding the 2D accuracy is usually pretty close, but the altitude is all over the place. It's currently reading -4m despite my being a good 8-10m above sea level (including being on the second floor). The other day at the same position, it started at 22m and gradually went down to -2m even though I hadn't moved.
Anyone else seeing this?
well...i don't have that particular problem...but i do get live search aquiring the gps location somewhere COMPLETELY away from where i'm at..almost 6-10 miles away to be exact. I usually do a soft reset and all is good again....google maps usually gets my location on point at all times...jus not as expansive in options like live search
Vertical Accuracy
Vertical accuracy of a gps is never near as good as horizontal accuracy. Its more a function of the way gps works than any inadequacy of your equipment. You should get within about 5 metres horizontally when you lock on 4 or more satellites. But vertical accuracy is rarely better than 20 metres.
For more information about why this is true check out http://weather.gladstonefamily.net/gps_elevation.html
Yes, that is pretty typical of any GPS. I believe it is improved if you have WAAS enabled, but we don't have that.
the GPS program that I have [VitoNavigation] gives an accuracy in ft. on my mogul. Normally it reads above 35 ft accurate. have not tested it yet to see if it really is that far off or if the program is not right...too cold outside

@d fix is just that. If you did not mean 3D fix then not surprised, as 2D is not the Z axis and you need a 3D fix, and it still will not be as accurate in the Z axis but should be better with a 3D than a 2D.
Umm... what?
Soundy,
That last post was a bit over my head too. (no offense intended madman, just that we didn't understand the jargon)
All i know is that the vertical accuracy you are experiencing is, unfortunately, about as good as it gets. Did you check out the link I posted before. It explains that the geo-spacial orientation of the satellites is the problem. To get a horizontal fix of your location, the gps receiver needs to see at least three satellites at different angles from your location and work out by triangulation where you are. Obviously if all three are located close to each other, the triangulation is less accurate and liable to slight - but amplified - inaccuracies in the angles that help your gps calculate your location. If the three satellites are right on the horizon relative to your gps location, at 120 degrees away from each other then you will get maximum accuracy because the angles are big and the slight error in reading these angles is proportionally much smaller.
To get a vertical location fix, the satellites that you lock onto in order to get an accurate fix need to be located at equidistant angular locations relative to your location not just in a horizontal plane like when getting a horizontal fix, but vertically as well. The only way to get the satellites in this orientation relative to your location is to have one of the satellites directly overhead and another three located in a tetrahedron format below the far horizon. Unfortunately the satellite signal cannot penetrate through the earth to get to you, so you have to rely on satellites which are above the horizon. Unfortunately these ones are therefore not located as far away (optimal) from the one directly above and so the calculation of the vertical elevation data suffers.
The same effect occurs on your horizontal accuracy when you have a fix on three or four satellites but they are all in the same part of the sky. Your accuracy, even horizontally will be more inaccurate too. Thats why its better to get 7 or 8 satellites in your sights. Its not just that 7 or 8 give more data than just 3 but mainly because they are more likely to be spaced out around the sky more optimally.
As the satellites move throughout the day, the almost random orientation of the satellites as the follow their own paths means that accuracy will go up and down as the pattern of satellites gets "better" or "worse" relative to your location.
Hope this helps

It does, thanks. I'm typically seeing 6-8 satellites, horizontal (2D) accuracy is usually pretty good... at worst it seems to be 6-10 feet off to the west (ie. it shows my position a little further west than it actually is). It's stranger to me that the altitude seems to "wander" so much - like I say, the one time it started at +22m and slowly went down to -2m... while I was sitting still

Wifi issue

Well it appears this is a design flaw!
When they where designing it they should have used some plastic! Using all metal backing makes the signal weak as hell!
Even if they can fix this problem idk! It would still be really weak!
For an example if you look at the ipad there is plastic for the Apple logo behind this is the wifi anttena!
Hopefully the back really is plastic and they did not overlook that problem! And it's just imperfections in the antenna!

I am pretty sure the Asus tech guys aren't totally dumb. I think they know about problems with WiFi and metal...
I guess the antenna is somewhere in the bezel. Anandtech (i think they were the ones) said that with their new unit wifi was okay, but it depends on the holding angle of the prime.
So it seems we DO have to take some comprises for having a full metal back. But I think I can life with that

Anandtech said the new unit was better, but not as good as the original Transformer in terms of WIFI.
Don't assume that ASUS is not capable of making such a stupid mistake. There have been lots of cases of top tier companies shipping out products with such design flaws, and I don't think ASUS is in the category of top tier company. I work in a fortune 500 company, and we get the first batch of a lot of laptops, and we test them before the workers get them. Sometimes I'm amazed at the lack of basic quality control when these devices first come out. It's like they ship out beta hardware.

There is not one doubt in my mind Asus wasn't aware that the WiFi was wearker than the TF101. However you have to realize unless the performance literally was unacceptable by whatever QC standards they have, they are able to pass the design, build the product, and ship it. Fact is only because a couple top tier reviewers recieved units that weren't up to the standards of the rest, they decided to handle the situation the way they did. In fact if they weren't aware of it, they probably would've let the stock stay as is, launch as normal, and say that "there are a small number of reported cases" as companies usually do.

This happened with Apple and the Iphone 4. The antenna was located in the bottom
right of the phone and signal was lost when you had your hand over it.
http://www.anandtech.com/show/5178/an-update-on-transformer-prime-battery-life-wifi-issues
"Using Ookla's Speedtest.net web app I get a consistent 34 - 37Mbps on the original Eee Pad Transformer (our actual WiFi performance tests involve downloading a file from a local server, but Speedtest was a quick and easy way to verify the problem). My original Prime review sample averaged around 0.5Mbps, while the replacement Prime got around 10Mbps - all in the same test location. Fiddling around with location I could get the replacement Prime up to 16Mbps. My test area is riddled with challenging interference so I setup a separate test area in another room. Even after buying the same Netgear WNDR4500 wireless AP that ASUS verified 31Mbps+ operation on, I wasn't able to break 16Mbps.
I have four other APs covering my house, I turned all of the radios off as a last ditch effort. Boom - 36Mbps on the Prime.
The culprit appeared to be either my 3rd gen Time Capsule or 5th gen Airport Extreme, with those radios off and using the WNDR4500 I was able to get performance competitive to the original Transformer. Here's where things get interesting. The original Transformer was made out of plastic, through which RF travels quite nicely. The Prime's metal construction makes things a bit more finicky. Indeed this is exactly what I saw, where depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range). "
I also think it's a mistake to assume that other reviewers would necessarily notice this problem. Other reviewers might not have tested WIFI performance at all.

No one is doubting the performance isn't up to par with the TF101. It's obvious it's not. Again Asus was well aware and thought it would slip by well because of something called everyday use. If it wasn't noticed by other reviewers it's for a reason, they tested it under normal use circumstances and found it to be quite acceptible. I am in no way making excuses for Asus or the design but it is what it is. Anandtech however doesn't test like that and which is why they were able to find such a flaw. It's all about a matter of usage.
I'm about to dump my pre-order. This whole release date debacle pissed me off, and now if there is possible WIFI issues...it might be a bad investment. I've been asking myself if I really need a tablet anyhow, and the answer is probably not.
please dump it.. saves it for the people who want it.

I'm glad I didn't do the pre-order thing. I don't want to be first in line for this. I'll wait until it is generally available, and there has been time for reviews of retail units. Let other people be on the bleeding edge
I have not been close to cancelling my preorder up to this point but if this wifi issue is confirmed I may be tempted to buy the original TF. Especially considering they keep showing OOS open-box Transformers for $185 on a particular website we all know and love. If I see one in stock I think I will go that route until this issue is worked out.
I wish some more reviewers would do in-depth testing on this issue.
I hope they don't make it thicker with a redesign! It seems line it already was redesigned once aka the one poorly placed speaker...

Haven't you ever seen a proper Wifi antenna? They at least as thick as your finger.
So they NEED to make it a lot thicker.
Otherwise we'll never get a proper Wifi signal.
You may better get a different device.

They were dumb enough to test the Wifi after they've mass produced the thing instead of before. What makes you think otherwise?
Folks, let's tell the whole story here. What Anandtech also said:
I have four other APs covering my house, I turned all of the radios off as a last ditch effort. Boom - 36Mbps on the Prime.
The culprit appeared to be either my 3rd gen Time Capsule or 5th gen Airport Extreme, with those radios off and using the WNDR4500 I was able to get performance competitive to the original Transformer.

Indeed this is exactly what I saw, where depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range). Apple gets around this issue in the iPad by putting the WiFi antenna behind the plastic Apple logo, however it's not entirely clear to me where the WiFi antenna is on the Prime (I have this policy about not taking things apart until I'm done testing them).
As to why performance was lower with the Apple APs active, I'm not entirely sure. Chasing down RF interference issues can be a severe undertaking. One thing is for sure, the Prime is going to be far more finicky than its predecessor when it comes to reaching peak speeds over WiFi.
Click to expand...
Click to collapse
I know that the folks at Anandtech are smart people, but it seems like the reviewer conflated some things here. I don't know how much testing he did AFTER turning off the Apple AP's, but it sure seems to me like the fluctuating results he's talking about were from before he did so. Perhaps the Prime is fine in general but just had an interference issue with the Apple APs that actually resolved itself just fine once they were turned off.
Why would there be this kind of interference with the Apple APs? I have no idea, except that it would point to something in software and not hardware. But until we have someone who does a really good job of detailing precisely where a non-defective Prime has wifi issues, I'm personally writing this off to something being broken in his first unit.
True, he did say he could get it to 36Mbps "depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range)"
This, along with:
ASUS feels the WiFi range does not currently meet their standards and has delayed all shipments worldwide. At the moment there is no ETA and noinformation on available quantities on the first batch.
http://forum.xda-developers.com/showthread.php?p=20155626
As a comparison, AnandTech shows the Kindle Fire's WiFi maxes at 15.2, and I couldn't get close to that in my own tests.
i posted in multiple threads my concerns about the wifi issue when the anandtech and cnet reviews came out. i've canceled my preorder at jr but will keep my adorama and bestbuy preorders for now though. all hype i had for this thing is completely gone. now i'm like whatever.
If Anandtech was able to get full WIFI speed turning off other AP's than that points more to an interoperability issue that should be correctable through firmware/driver rather than antenna/hardware design.

Wifi Video Comparison of TF101 vs TF201

youtube.com/watch?v=nzCZc3pjtrA
Not created by me, but I found it interesting, so thought I would share.
At least on my prime, I have found that the wifi signal is comparable to my epic 4g touch, which I am pleased with.
Sent from my Transformer Prime TF201 using Tapatalk
It seems that the Prime CAN get the same WiFi speeds as the TF101, but the main problem is that the farther away you are and the more objects in the way the more adverse the results are for the TF201 over the TF101.
Maybe asus should have brought the antennae like right up behind the glass of the screen.
I would like to see someone do a video show casing the differences of facing the front of the TF201 away, towards and sideways from the router to see how much it affects the signal.

I don't have a video, but I can tell you that in many tests I have done, whether the screen faces the router or the back does, it doesn't seem to affect the speed. which makes me hopeful, maybe it's something that can be fixed with software.
I'm undecided on keeping it or returning
I'm also trying to decide between keeping and returning my Prime solely due to the weak Wifi. I'm hoping there are some tweaks in ICS that improve it, but I have a crappy feeling that it is indeed a faulty hardware design and we're screwed if we expect to ever get decent Wifi range and speed with this tablet.

This is my video, and note that I purposefully did this test with the back facing the router. My response was to a different question--switching "sides," not specifically switching orientation.
I should do another video, because in fact when the Prime's glass is facing the router, wifi speeds are significantly improved. I'm going to annotate my current video and consider doing another one showing the difference.
The issue doesn't seem to be getting a high speed and strong signal, it appears the signal can be inconsistent. You wouldn't even notice in stuff like browsing that use the signal intermittently. If there's an issue it would show up on constant streams like video and downloads.
Truthfully, Wi-Fi is one of the most difficult areas to compare results in. Between the different conditions and age and make of the routers you can only compare to what you know and are familiar with. For example, the SGS2 hates D-Link and loves NetGear. It took forever in their forum to figure that out.

I'm sure they'll fix it either with software or with a hardware revision where everyone will have to warranty it. Early adopters are the beta testers these days in the tech world, so that's why I always wait two months to get a device - it's tough, but at least you don't have the problems.

New Prime Owner Checklist

Hi,
I am expecting delivery of my Prime from Amazon next week. I have been closely monitoring many problem threads on this forum, and I am starting to loose track. I was hoping for some help. I want to have a checklist of things to test so that I can make a reasonable decision on whether to keep, return for a full refund, or swap out for a replacement. I think Amazon gives me 30 days. So here is what I have so far.
OTA bricks systems?
Bleeding on the screen (I don't even know what this means... can anyone clarify?)
Dead/bad pixels on the screen
wifi performance
wifi+BT performance
GPS (despite Asus basically throwing in the towel on this)
HDMI audio (of 5.1 audio only?) output all going to one channel
Switching performance modes results in low image quality
TouchScreen response in the corners when charging
Any others?

A cheaper version of the Prime. The only difference really is not a sharp looking (cheaper materials) and no Super IPS+ display making it easy.

Aside from the fact that the battery life isn't quite as epic as the Prime's, our most serious complaint has little to do with ASUS, and more with Android: even with a state-of-the-art chip running the latest version of the OS, the tablet occasionally hiccups when launching apps and resizing web pages.

to be honest, I've seen breakdowns on wifi performance comparisons. the 300, according to those charts, does perform better on wifi across various distances from router. It can also be said alot of prime owners don't have an issue with their wifi. I think it may have been Anandtech review where i saw the comparison charts. I cant remember. Either them or Android Central. If i come across it again ill link you to it.

I'm confused... Are you saying that if our Prime performs similar to that chart then we don't have a problem?
Looking at that chart, I see that the Prime is obviously the worst performer and it seems to be a pretty big issue compared to the other tablets.
>http://www.anandtech.com/show/5756/asus-transformer-pad-300-review/5
I wouldn't draw any conclusion from this chart. It's not representative. The numbers are distorted, likely from variations from a single test.
Per the chart, the Prime would have better wifi at 50' + multiple obstructions than at 20' + single obstruction, which obviously is false. Ditto for TF300, which from this would have same wifi performance at 20' as at 80'.
When a single set of numbers is known to be wrong, then the whole work is suspect. I would look askance at the entire review. This is shoddy work. I expect better from Anandtech, especially when Anand dude himself put his own name on the article.

you confusing me..lmao did you see the post i quoted? the original question was asked how does the 300 wifi performance compare to the prime. i gave the Anandtech comparison he did in his in depth review. Anandtech did a prime wifi tests early when prime first came out. his tests didn't fare well with the prime. my prime gets results more similar to the other devices listed. not all primes have wifi that perform bad, especially newer units.
Either way i just linked the person asking the question to a comparison chart showing how well 300 wifi performs. this has nothing to do with the prime by itself. this is just a recorded proof of comparison. that's all really. Since no other tech site has done what the person asked about so far.
what e.mote said is true also.

Per the chart, the Prime would have better wifi at 50' + multiple obstructions than at 20' + single obstruction, which obviously is false. Ditto for TF300, which from this would have same wifi performance at 20' as at 80'.
When a single set of numbers is known to be wrong, then the whole work is suspect. I would look askance at the entire review. This is shoddy work. I expect better from Anandtech, especially when Anand dude himself put his own name on the article.

That chart tracks with my experience and likely the experience of most other Prime owners. The TF300 has slight dropoff, but consistently strong reception out to a much farther distance. The Prime has significant dropoff quickly, and almost total dropoff at the longer distance.
Both Primes I have owned were exactly the same as the one tested. Within 20 feet of the router, some dropoff. Outside of 20 feet, at least half, and at 60+ feet almost total dropoff. Also, it's reasonable that the 50 foot test was a little stronger than the 20 foot test because of the randomness of the signal dropoff. Sitting 50 feet from my router, I could run the speed test five consecutive times and get five different numbers. That doesn't make the numbers suspect, it makes the Prime's reception suspect because you get such random results.
You can make excuses and call the numbers "suspect" all day long, but I think a lot of Prime owners find those numbers very believable based on actual experience. I just think it's tragic that Asus CONTINUES to pretend that WiFi isn't a real issue, and continues to sell the Prime as the premium product even though it suffers from such a tragic flaw that doesn't seem to plague the "lower" model with the plastic back. Shipping an external GPS antenna to the obvious GPS problem was a nice step, but they still haven't done anything to make WiFi better. IMHO, a new caseback was the only viable solution and they have steadfastly refused to do it.
Asus should offer a trade-in program and see how many people would trade them their current Prime straight-up for a new TF300. That'll be a good indication of which one people think is actually the better product.
>it's reasonable that the 50 foot test was a little stronger than the 20 foot test because of the randomness of the signal dropoff.
OK, removed the "extra-curricular" commentary. Here's the sanitized version:
There are only 4 wifi numbers given for the Prime, one of which (50') is clearly wrong. If you accept that the 50' number is wrong due to "randomness", then the rest of the numbers have no credibility, because they can also be affected by the same "randomness." Hence, the need to minimize testing variability and to publish your testing method.
Wifi tests are highly variable, and you would want to minimize variability by taking some steps, the first of which is to test multiple times, remove the outliers, then normalize the result. The second of which is to publish your methodology so the test can be replicated. The Anandtech piece did neither.

Totally agree with you.
Does anyone know the reason why Asus decided not to change the back cover of his Prime?
Because if it's just only for aesthetics, it would be stupidiest reason ever held.
I would like to buy a Prime right now, the best of all Android devices, even with another backcover not-so-cool.
But seeing that problems I prefer buying the TF300 or go to another brand.
What a pity!

If I had to guess, I'd say it's the obvious answer -- money. If they replace the back cover, then they have to do it to every unit, at a support center, by trained technicians. They're already struggling to keep up with basic repair and support -- a total retrofit would be an insurmountable task for their current infrastructure.
If they ignore the WiFi problem completely and just "fix" the GPS, then they can manufacture an external part, mass-produce and package it, and mail it out to some percentage of their registered owners with no other cost to them.

I continue to find these posts humoring. Have you looked at a dissected Prime, either here on XDA or at Anandtech? Everything but the glass and LCD is attached to the backplate. That means either several hours labor swapping all the parts from one back to another or just trashing the entire back assembly and replacing all internal components.
So, in short and as mentioned, money. Either of those circumstances is no bueno for ASUS's bottom line, and therefore neither one is happening.

Which also explains why not much availability. The 300 will be their mass production device.
This is SPARTA!!

Practical tests are best. Take two devices and compare when each becomes unstable and then stops working with wifi. For me, the Prime was about half as functional for signal compared to the Thrive, View and iPad.
Though good enough for some, not for others. Seems logical to fix the back panel on new production runs and maybe they would have, if the 300 and 700 were not releasing now/soon.
