I am thinking may be it is not only 4x4. The iPhone X also has problems as compared to iPhone 8. So, I'm struggling to intrepret the data.
It appears to me that the XR would have substantially better functionality than XS in low signal areas using and mhz bands 12, 17, 71? I am primarily referring to the ability to make and recieve calls in very low signal areas with some rudimentary web browsing. Could you please explain how to read the graphs?
Is closer or above to mW better? My articles really are not intended for the general public and typical cellphone users, but rather for those who already have reasonable understanding of cellular RF communications.
So, I may not always provide basic explanations of my analyses and graphs.
I purchased the iPhone XR and have been very pleased with the performance in a very rural area. I was able to make calls and maintain an lte connection when several other phones could not even make a call. Thanks for making the information more accessible. I realize this is off-topic, but would you be able to assemble graphs for the Note 9 Snapdragon model?
Typically, iOS devices have their authorization filings posted right before the devices go up for sale to the public. This tradeoff of fewer antennas and MIMO channels, though, ostensibly has allowed for greater antenna gain and, concomitantly, higher radiated output power compared to those same metrics on the iPhone XS and XS Max.

Right now, the S7 and S7 Edge are the only two devices updated to use the technology - although it's our aim for additional equipment to support it, at this time we don't have a list or timeline. Crossing my fingers that your iPhone which coincidentally is the phone used by several of my colleagues is one of those that can take advantage! Friend of mine from Qualcomm told me.
They do support They are simply missing the required antennas. I am trying to see if he can legally share documentation to aleviate the he said she said thing. He did say this is based on a 4 month old documentation which could have changed more than likely not due to release schedule deadlines.4x4 MIMO - Does it make a difference?
Please type your message and try again. Does the device have the hardware capable to support this? This content has been marked as final. Show 3 replies. All replies Hi gregt1! Go to original post Log in to reply. Retrieving data Contact us We're here to help.Peter Cao.
With the iPhone XS and iPhone XS Max a few days away from releaseusers are dying to get as much details about the new phones as possible.
From the first round of tests, it looks like the iPhone XS has massive gains against its predecessor, the iPhone X. For those unaware, it may look like Apple has finally cracked the code on wireless networking.

Such is the case with wireless acronym MIMO multiple input, multiple outputwhich got some additional letters with the release of MU-MIMO a few years ago and is on the verge of becoming more popular with the release of the forthcoming MU-MIMO stands for multi-user, multiple input, multiple output, and is wireless technology supported by routers and endpoint devices.
2018 iPhone Could Have a First for Apple Phones
MIMO technology was created to help increase the number of antennas on a wireless router that are used for both receiving and transmitting, improving capacity for wireless connections. Standards older than When the standard came out a few years ago, only routers and access points supported the technology. MU-MIMO was created to support environments where multiple users are trying to access the wireless network at the same time. The nature of the While these times can be miniscule, it can add up with more devices smartphones, tablets, computers, etc.
MU-MIMO technology breaks up the available bandwidth into separate, individual streams that share the connection equally. With MU-MIMO, instead of one lunch lady, you now get two, three or four lunch ladies, which lessens the time you need to wait. However, there are some rules regarding this. First, the streams are spatial, which means if two devices are close to each other, they still have to share the same stream.
Imagine that cafeteria scenario again, but this time the four lines that were created are now points on a compass. Second, the technology only works for downlink connections. This is great for home users who will likely need faster speeds for 4K video streams and online gaming, but less useful for business workers who need faster uploads for content creation such as video uploading or two-way video conferencing applications.
In addition to supporting 8x8 arrays, the coming-soon Initial The standard is also designed for dense environments such as airports, stadiums and urban apartment buildings. So the future is bright for MU-MIMO as it expands its capabilities and more devices become able to utilize the benefits.

UniFi nanoHD 4x4 For RVers and Cruisers, understanding what MIMO technology is, how it works, and how it can be used to enhance cellular speeds has the potential to make finding great mobile internet on the road an easier experience.
For anyone who knows a thing or two about wireless communications, modern LTE cellular radios are borderline miraculous.
A bit over a decade later - the latest flagship cellular devices can support maximum theoretical speeds of over 1,Mbps. And in the real world - you will be sharing this speed with perhaps hundreds of others connected to the same cell tower.
Best Reason to Upgrade to iPhone XS? The LTE Speeds
But real-world LTE speeds over 50Mbps are actually not at all uncommon nowadays, and speeds over Mbps are starting to be widely reported - and things just keep getting faster.
One of the key technologies making these sorts of speeds possible is known as MIMO Multiple Input, Multiple Output - an incredibly clever technique for putting multiple antennas to work to increase both data transmission speed and reliability.

Traditionally, a device had just a single antenna inside it. However, there are also devices with more antennas. Each antenna on a device is used both for receiving data and sending data. The more antennas your device has, the more data it can transfer at once—and that means faster wireless download and upload speeds. Think of it like lanes on a highway.
If you have a four line highway, more traffic can flow through at the same time than on a two or one lane highway. But cellular and WI-Fi have separate antennas. They can all support four separate data streams at once when connected to a cellular network that offers them.
However, that only refers to the cellular connection. The cellular and Wi-Fi antennas are separate. The more MIMO, the better. Overall, the faster wireless speed and improved signal strength are always good to have. You may just have to pay extra for devices with this feature. Comments 0. The Best Tech Newsletter Anywhere.
