AppleInsider claims that Apple is planning on incorporating support for the new faster 802.11ac Wi-Fi specification into products this year.
The new 802.11ac standard achieves much faster wireless networking speeds than the existing 802.11n specification (in use on the latest Mac, AirPort and iOS devices) by using 2 to 4 times the frequency bandwidth (from 80 to 160MHz), more efficient data transfers through sophisticated modulation, and more antennas (up to 8; existing standards support up to 4, while Apple's Macs currently use up to 3).
This "Gigabit WiFi" offers speeds 3 times as fast as existing 802.11n wireless networks can with speeds of over 1 Gigabit per second.
Despite the specification not being finalized, Broadcom has already announced a family of chips supporting 802.11ac Wi-Fi. The final specification is expected to be certified in the second half of this year.
Apple and other manufacturers have been known to deploy un-finalized wireless technology in the past. Apple deployed 802.11n in new AirPort base stations years before the official standard certification.

Apple is planning a series of "major design" and "format changes" for iPhones over the next few years, according to The Wall Street Journal's Aaron Tilley and Yang Jie.
The paywalled report published today corroborated the widely-rumored "iPhone 17 Air" with an "ultrathin" design that is thinner than current iPhone models. The report did not mention a specific measurement, but previous...

Apple today seeded the first betas of upcoming iOS 18.3 and iPadOS 18.3 updates to developers for testing purposes, with the software coming a week after Apple released iOS 18.2 and iPadOS 18.2.
iOS 18.3 and iPadOS 18.3 can be downloaded from the Settings app on a compatible device by going to General > Software update.
There's no word yet on what's included in iOS 18.3 and iPadOS 18.3, ...

Apple is working on a redesigned Magic Mouse that will address some "longstanding complaints," according to Bloomberg's Mark Gurman.
In his Power On newsletter today, Gurman said Apple in recent months has been working on a "full overhaul" of the Magic Mouse with a design that "better fits the modern era." However, he does not expect the new Magic Mouse to be released in the "next 12 to 18...

Apple plans to release a second-generation AirTag next year with "considerably" longer range for item tracking, according to Bloomberg's Mark Gurman.
In his Power On newsletter today, Gurman said the new AirTag will use Apple's second-generation Ultra Wideband chip, or equivalent technology. The chip debuted last year in the iPhone 15 and the Apple Watch Ultra 2, and Apple said it offers up...

The current Apple TV 4K was released more than two years ago, so the streaming device is becoming due for a hardware upgrade soon. Fortunately, it was recently rumored that a new Apple TV will launch at some point next year.
Below, we recap rumors about the next-generation Apple TV.
Bloomberg's Mark Gurman last week reported that Apple has been working on its own combined Wi-Fi and...

Apple on Monday seeded the first tvOS 18.3 beta to developers for testing. The update will likely be released in January. So far, there are only minor changes for the Apple TV, with one new feature and a few code changes discovered.
Below, we outline what is new in tvOS 18.3 so far.
Robot Vacuum Support in Home App
First, tvOS 18.3 will add robot vacuum support to the Home app on the...

Late last month, The Information's Wayne Ma claimed that the rear of the iPhone 17 Pro and iPhone 17 Pro...
Will this standard support the bandwidth capable of wireless video mirroring of a hypothetical retina iPad 3 using a hypothetical Apple TV 3?
Another thingis it too much to ask that the numbering system for these standards go a, b, c, d, e instead of a, b, g, n, ac? Because in 15 years well end up with something stupid like 802.11no.
I know people like my grandma will ask is n newer than ac?
And another thingI wish USB updated this often. Make everything backwards compatible like it is now but just update the speed every few years instead of waiting. Then most computers today would have at least a fairly speedy USB port compared to 2.0.
How will this work in congested wifi signal areas?
It is bad enough maintaining a clean signal when my neighbours use 40MHz, let alone 80 to 160MHz
In actual fact. the 5GHZ band takes you AWAY from congestion. The 2.4 band is where the interference is at present. My TC operating at 5GHZ and 2.4 (it auto switches) gives a far better connection on my IOS devices than the older standard ever could.
I hope that the speed can be promoted up to 10 Gb/s very soon. Then, a computer display, such as an Apple Thunderbolt Display with WIFI capability, can be connected to a desktop computer, such as a Mac Pro or a Mac mini, through WIFI, which will be the beginning of a new computing era.
WiDi does just this, it's Intel's implementation of the WirelessHD protocol (60 Ghz or if you will, IEEE what 802.11ad will define under the umbrella of WiGig, a competitor of WirelessHD).
On-topic : It will be nice to get a bump up from 802.11n, but frankly wireless is abysmal regardless and reaching the theoritcal top speeds is never easy, even standing next to the base stations. I do get a giggle in these threads when the uninitiated though think we can't really do stuff like stream "1080p full HD" without these advances. 1080p streams just fun already over 802.11n, it's not a matter of pixels but of compression and bitrates.
----------
The 802.11 standards set implements wireless technologies in a set of frequencies. Each of the letters you see after '802.11' count up alphabetically from the first incarnation of the standard. 'a' and 'b' you're familiar with, 'c' to 'f' and 'h' to 'k' cover other standards that the 802.11 group have created to work with wireless LANs.
Just to further drive the point home :

Notice how 802.11ac isn't due for ratification until December 2012. So if Apple offers it before that, we'll be getting a "draft" implementation like we did with the original 802.11n.
