New Apple Patent for Multi-Antenna System


Recommended Posts

On Tuesday the USPTO published 22 new Apple patents. One of them specifically relates to LTE and Multi-Antenna systems in the iPhone.


Apple has received a Granted Patent that relates to the field of wireless communication and data networks. More particularly, Apple's invention is directed to the efficient allocation of time-frequency resources of a wireless communications system using multiple antennas, including the asymmetric distribution of data streams among the antennas.


Apple's patent discusses the various antennas utilized in the iPhone and related standards such as LTE, UMTS, MIMO, 3GPP, OFDM


Another section in the article describes data access methods, specifically:


For LTE, new multiple access methods have been specified in Apple's patent. For the downlink transmission direction, OFDMA in combination with TDMA has been specified. OFDMA in combination with TDMA subsequently referred to herein as OFDMA/TDMA, is a multi-carrier multiple access method in which a subscriber is provided with: (i) a defined number of subcarriers in the frequency spectrum; and (ii) a defined transmission time for the purpose of data transmission. Uplink data transmission is based on SC-FDMA (Single Carrier Frequency Division Multiple Access) in combination with TDMA.


Maybe Apple has really over-stepped their boundaries this time.


Comments are encouraged. I wish I had time to look through the whole patent, but most of that jargon baffles me at this time.


The article mentions 2 other granted other patents as well, one of which covers the case to the iPod Shuffle 4th Gen, but the LTE patent certainly seemed important to share.

You mean that dry, technical jargon is not easy to read at 330 in the morning? Preposterous Josh!


Man, it's not easy for me to read period. One of these days I will understand what I'm reading, but for now I don't. Nothing to do with time of day.

Surprises these were granted so quickly...I remember the LTE antenna one being applied for not too long ago...least it was brought up on some site that they applied for it not long ago...

    • Luckily, that hasn't arisen in my area where I am, aside from having B14 (well, ALL of AT&T signal) not work at all in Coosa county, Alabama. I wish there was a service for first responders that would go to ANY available carrier, provider, etc..and in the absolute worst case scenario, would give us service. I've been on an ambulance, trying to find an address, and my driver actually had to pull over and we pulled out a map book and tried to find the road using the "old fashioned way".. and that takes valuable time away that sometimes may be vital to someone surviving. BUT, I will say that I've only seen that in Coosa county... both my Tmo and AT&T phones had zero service and I couldn't get GPS, and neither could my driver (VZW service). Maybe satellite will help with that in those times where that occurs.. but that's an extreme example.     Edit to add: Let me add some context to this.. Coosa county isn't regular coverage area for my job.. so it's not a regular thing that we are dispatched to Coosa county.. and actually, there's been a change and that county now has it's own ambulance service that operates.. so the only time we might receive a request is if it's a multiple casualty scenario, or it's a transfer going home from our contracted hospital.  The way that reads above, it may seem like we are just out without some sort of GPS gadget to direct us on where to go, but for the most part, we know our coverage area pretty well. Dispatch can also give us cross streets for reference inside our coverage area (and our home county). Coosa just isn't a regular area for my job to run in. 
    • "Priority" doesn't mean "exclusivity."  When emergency services don't need B14, AT&T can use it for everyone else.  The trade-off is that when it is needed for emergency services, they not only get all of B14, but they have also arranged for priority on the rest of the AT&T network as well.  Beats having spectrum sitting unused most of the time and then not having enough when disaster strikes, as it could be without a partnership with a wireless company like AT&T. - Trip
    • I've wondered if being on the first responder plan has the priority over other 'regular' lines in the same way firstnet does (or, supposed to do with B14...I've seen normal customers on AT&T hit B14 so it's not {specifically} for Firstnet only)...  
    • T-Mobile prices people pay are all over the map. The free lines are key, so take them if ever offered again.  Your priority level would be a key factor for your price.  Only T-Mobile would know the average prices people pay.  Samsung has been offering very good deals at time of new model introductions so I have gone that route for factory unlocked, which allows me to also have a Verizon priority MVNO for when T-Mobile signal fails or I manually override.
    • I also wanted to post a speed test result.. I only do these once in a while from my home area because we are gonna be the last to see changes, like load balancing.  Right now they are digging all over the place for fiber installs, so I'm not sure what the hold-up is on making the upload speed a little more in-line with download speeds, but here is the most recent from my area:   https://www.speedtest.net/my-result/a/10133670525
