I have a Max on Sprint and have to constantly put it in Airplane mode and toggle it on/off for the network speed to get back to LTE speeds. It happens several times a day and it’s not Sprint as it doesn’t happen with other phones.

That's not exactly the full story. Here's what the original "expert" from WiWavelength believes posted 9/26:

"Now that many users are reporting numerous, varied cellular and Wi-Fi networking issues, I do believe that the Intel baseband and/or iOS firmware is at least partly responsible for those user issues. While any antenna shortcomings are impervious to a software patch, the Intel baseband and iOS firmware likely will improve with updates. How much improvement remains to be seen.

AJ"

It sounds like the issues can be greatly improved/minimized by OS/baseband software despite the characteristics of the antenna due to 4x4.
He states that it remains to be seen how much they can improve it with software, and you take that as the issues can be greatly improved. Lol

Here's my Speedtest results. Both taken several times on my work Wifi at the same time (Spectrum internet).

First one is from my Dell work laptop. Second one is from my iPhone Xs Max (256GB Space Gray on AT&T).

Weird indeed. AT&T LTE also seems to be suffering. Used to pull 15-25 Mbps on my iPhone 6s+. Getting 2-5 on my iPhone Xs Max. We are on their highest unlimited plan and it's the end of our billing cycle. Maybe we're just being throttled for some reason, but I'm not sure.

Can you put it in field test mode and let's see what band your on ?

It's more like some people want to wait for facts and evidence before deeming someone guilty (not a reference to current day politics at all either). What I've been preaching over and over now; no one is right or wrong yet, simply wait (or return your phone if you cannot).

Maybe this is an Intel coding issue in their modem baseband and Apple has NOTHING (or very very little, no one knows who does what part exactly in secret) to do with it.

Buh buh buh Apple tho!! No one knows squat yet.

Oh Christ.... WiWavelength Report the "Facts" from FCC, and interpret them with his knowledge.

Then people who has absolutely no technical knowledge ( as usual these days ) misinterpret it. I mean if you don't know what -db, RSSI, SNR ,BER, or other basics why are you even trying to discredit WiWavelength?

The software update may ( or will ) improve Data Rate, and connections drop. Looking at these report it is highly likely the firmware for Intel Baseband is not quite finished. The original announcement for XMM75 Series were based on CEVA IP and should have come with ARM instructions set as with all previous Intel modem. For better or worst the new 75 series comes with an embedded x86 processor inside the baseband.

But the sensitivity of those antenna is a done deal. Apple traded higher transfer speak for slightly / much lower reception quality. It seems the 2x2 on Xr is even better than the iPhone 8 and X.

Why would they make that trade ?

And what exactly is his knowledge? His profile on that site describes him as “Armchair engineer & communications policy wonk.”. No qualifications listed. No industry experience listed. I’ll bet no-one on here had heard of him or his site before last week. He may be right, he may be wrong, but why on the above evidence should we believe he knows more about antenna design than anyone else in general or, specifically, the cellular engineering team at Apple who, unless you believe they intentionally designed a faulty product, clearly thought that the antenna would perform ok?

P.s. if you look at his site, the last postings before September 2018 were in 2013. If he’s some sort of industry expert who follows these matters closely it’s odd that he’d break a 5 year silence just in time to comment on this, isn’t it?

Plus 99% probably have never heard of macrumors and are unaware of this problem.

I heard a rumor that you got banned on the Apple support forums is that true ? I have noticed a bunch of postings being removed over there that have to do with cellular reception issues.

I have the Intel modem iPhone X from last year and it has never gotten better.
You really notice it in places with not the greatest reception.
Also driving on a trip, it would go from LTE to 4G to nothing.

I wouldn't expect a software fix because mine didn't get one.

Interesting question. Maybe they know the majority of XS customers will be in decent reception areas?

Yes, if you have good LTE signal, the 4x4 and other new features will make it faster than older iphones. When the signal gets weaker, those features don’t matter as much, and the antenna performance is more important.

My XS Max has ok LTE, but WiFi is very weak. The 5Ghz band drops 15ft from the router, and 2.4Ghz also stops working at a shorter distance than an iphone 6.

If your wifi is bad then your cellular is fine . It's either or so far with the XS for whatever reason since launch

I cant complain about my wifi. I have an Airport TC and set it up with my 5Ghz channeled labelled different that the 2.4. Throughout my house I get strong reception and fast speeds. Just as fast as all my other phones.

You make some good points. The requisite qualifications are always an important consideration in giving weight to an opinion of someone who purports to be an expert. But I can tell you from first-hand experience that even someone with impeccable credentials can provide incorrect opinions. I've cross-examined engineering experts in patent litigation trials. I can recall occasions where experts with great pedigrees from top-notch engineering schools have changed their opinions after being cross-examined on their assumptions of the underlying facts and their conclusions. I cross-examined one expert who was so prolific in his publications that he'd forgotten a paper he'd written years before that directly contradicted his current opinion. That removed a very smug look from his face.

Also, of course Apple's talented cellular engineering team didn't intentionally design a faulty product. But Apple also has other teams, including an industrial design team, that may place some restrictions on the antenna design because of other considerations.

The only thing we have at the moment are posters' reports of their cellular reception and one person's technical analysis of testing data submitted by Apple to the FCC. But I find this discussion interesting, so I keep following this thread.

Wow apple banning people from their site from talking about this issue......Sounds like people with this issue that its time to return it. Why hold on to a $1000.00 plus phone that cant even keep a slow connection..........

I was thinking more eastern America. Appalachian Mountains. I live in a small city, not rural, not urban. But there is a lot of topography that interferes with signals in my area. Mountains, valleys. Add in major cities 1.5 to 2 hours away and farm land all-around and it's a perfect testing ground.

I'm on the east coast, but I can't think of an environment that isn't closely mirrored wtihin 4 hours of SF. Midwest? Central valley. Mountains? Go north a bit? Big city? SF. less dense 'burbs? Sacramento-ish.

It sounds like the issues can be greatly improved/minimized by OS/baseband software despite the characteristics of the antenna due to 4x4.

We'll see. I'm very skeptical, since it sounds like there are antenna limitations at play here.

Problem is, literally no-one outside Apple knows whether that is the case or not (including the guy over at wiwavelength, the website no-one had ever heard of until a few days ago written by a guy no-one has ever heard of with no apparent qualifications). Yes, there is the FCC filing but whether those figures translate into a hardware problem that affects real-world performance rather than this being a soft/firmware issue is unknown at this point.

The data is the data. The interpretation of it is key, but the guy at wiwavelength isn't making anything crazy up based on the data. It's pretty clear that there's an issue here. He did posts like that in the past, they just weren't nearly as popular as they are now.
