    Communications chip maker Broadcom today announced a new 5G Wi-Fi Multiple Input Multiple Output (MIMO) system-on-a-chip (SoC) designed for smartphones, bringing 802.11ac connectivity with 2x2 MIMO to mobile devices.

    The Broadcom BCM4354 chip marks the first implementation of 2x2 MIMO for smartphones, bringing up to twice the Wi-Fi performance with 25 percent more power efficiency than the current 1x1 MIMO chips.

    Some smartphones, such as the Galaxy Note 3 from Samsung have previously incorporated 802.11ac Wi-Fi using single stream chips such as the BCM4335 from Broadcom, but the new chip uses two spatial streams for speeds up to 867 Mbps.

    MIMO is a technology that uses multiple antennas for both the transmitter and the receiver to improve communication performance. Apple first adopted MIMO technology for the iPad Air and the iPad mini with Retina display.

    Broadcom's chip also uses the newer 802.11ac Wi-Fi protocol for transferring data, which is considered "Gigabit Wi-Fi" with transfer speeds up to three times as fast as 802.11n networks. With the addition of Broadcom's Transmit Beamforming technology, photo and video uploads can be twice as fast at crowded events.
    Apple uses Broadcom's technology in its line of Macs that support 802.11ac, including the newest MacBook Air, Retina MacBook Pro, and iMac. Broadcom also provides the Wi-Fi/Bluetooth chips for Apple's iPhones, so it is possible that the iPhone 6 will feature Broadcom's newest chip, marking the first iPhone with 802.11ac support. Previous iPhone 6 rumors have also pointed to 802.11ac support.

    We'll see this in an iPhone in about 6 years.

    For when 4G's are not enough.
    Also, that kerning on WiFi is unnerving.

    The next thing that android phone makers can tout about on a specs page but no one will benefit from for a few years..

    Creative marketing (to call it 5G). Great, it has receiver and transmit diversity to reach WiFi speeds no phone could ever take advantage of anyway.

    I think we will see it before then, Apple is much better about keeping up with trends than they used to be...

    Considering no one has the bandwidth to take advantage of 802.11n routers, I doubt AC is all that significant right now.

    What good is a fast WiFi protocol when bandwidth is the bottleneck?

    The best I can get piped to my house is 105 Mbps. My several year old 802.11n Airport is capable of 3x that speed.

    Got any other ideas, Broadcom?

    Faster data is always welcome. But it costs me $30 to download an iTunes movie rental on AT&T. ($15/GB)

    Someone needs to start offering data rates that make sense with modern usage. That's where we need new tech and competition.

    Are they seriously applying the term "5G" to wifi? Do these people not give a damn how confusing this will be to consumers? Do we need to file a class action suit, or will someone in either the FCC or FTC step in and require them to stop using misleading marketing?

    Whence 1-4G WiFi?

    Am I the only one who doesn't recall ever seeing any type of WiFi branded with a "#G" label? Feels like they are trying to copy the marketing of cellular technology generations. (And making it sound really good by calling it 5G when cell phones are merely at 4G.)

    Cool stuff, but the logo again, horrible. Who's designing this crap :confused:

    Probably made with Microsoft Word..

    Maybe 5G will move up and be implemented before 2020.

    Until every data providers offer unlimited data this is really useless.

    I really hope this will be use in an iPhone 6, and Apple would finally made Airdrop between iOS and Mac available.

    Finally. Bring it on to this year's iOS devices. My Airport Time Capsule AC is waiting and I am hoping this will vastly improve Airplay performance for gaming :)

    But it is the 5th Gen wi-fi, isn`t it? a, b, g, n, ac. Not to be confused with 5G cellular.

    Well I see that only just about everyone managed to comment on that between the time I read the comments and wrote the above. :eek:

    This blood is on your hands, Broadcom.

    No, it's the sixth revision. 'a' is the second. http://en.wikipedia.org/wiki/IEEE_802.11#Protocol

    Google seems to be working on that.

    At least in a few selected cities. :)

    Not all of one's data transferring has to be to/from the Internet. The increased bandwidth could be noticeable for transfers between other devices on your local network.
