Broadcom Launches First Chips for Gigabit Speed 802.11ac, Foundation of 5G WiFi

[btarunr]

Broadcom Corporation, a global innovation leader in semiconductor solutions for wired and wireless communications, today introduced its first family of 802.11ac (5G WiFi) chips designed for a broad range of product segments. The new IEEE 802.11ac chips are three times faster and up to six times more power efficient than equivalent 802.11n solutions. Visit Experience Broadcom @ CES for more news, blogs and multi-media from CES and www.5GWiFi.org for more information on consumer advantages of 802.11ac.

5G WiFi is the next generation Wi-Fi standard required for today's mobile and video era. Based on 802.11ac, 5G WiFi is a major evolutionary step from the existing 802.11a/b/g/n networks. Broadcom's 5G WiFi dramatically improves the wireless range in the home, allowing consumers to watch HD-quality video from more devices, in more places, simultaneously. The increased speed enables consumers to download web content from a mobile device faster and quickly synch large files, such as videos, in a fraction of the time it would take on a similar 802.11n device. Since 5G WiFi transfers the same volume of data at a much faster rate, devices enter low-power mode faster, which results in significant power consumption advantages.



Digital-content consumption is on a steep incline, with video content expected to reach approximately 90 percent of global consumer traffic, according to Cisco's 2011 Visual Networking Index Forecast. At the same time, Internet traffic is shifting rapidly from wired to wireless networks. The increased reliance on wireless networks, the explosion of video consumption and the growing number of wireless devices being used are all putting tremendous stress on legacy 802.11a/b/g/n networks. As a result, consumers are prone to experience deteriorated performance, choppy videos and slower load times.
By creating more reliable whole-home coverage, Broadcom's 5G WiFi technology overcomes the digital content and wireless device challenge. Broadcom's family of 5G WiFi solutions includes the BCM4360, BCM4352, BCM43526 and BCM43516.

Product Highlights

• All 5G WiFi solutions from Broadcom support the following features:
  o 80 MHz channel bandwidth that is 2 times wider than current 802.11n solutions
  o 256-QAM, a higher modulation scheme that increases data transfer efficiency
  o Transmit and receive beamforming
  o Low Density Parity Check (LDPC) Codes
  o Space-Time Block Codes (STBC)
• BCM4360 supports the PCIe interface and implements 3-stream 802.11ac specifications, and reaches speeds up to 1.3 Gbps.
• BCM4352 and BCM43526 implement 2-stream 802.11ac specification to reach up to 867 Mbps. BCM4352 supports PCIe interface; BCM43526 supports the USB interface.
• BCM43516 supports USB and reaches speeds of up to 433 Mbps with its single stream 802.11ac implementation.
• Chips with the PCIe interface are ideal for access points, routers, DSL/cable gateways and PC products; chips that use USB are ideal for consumer electronics devices including televisions, set-top boxes and Blu-Ray players.
• Broadcom's new 5G WiFi chips deliver better coverage and longer battery life in a small form factor that is interoperable and compatible with existing technologies.
  o Beamforming helps steer content in the direction of the intended receiver, increasing reliability and extending range; this is well complemented by STBC and LDPC code support.
  o By transferring the same volume of data at a much faster rate, devices go into a low-power mode faster than existing 802.11n solutions.
  o Designed on 40nm manufacturing process, the new chips are smaller and more power efficient, giving customers more design freedom.
  o Broadcom's 5G WiFi solutions work with all legacy 802.11 standards and complement other wireless technologies - like Wi-Fi Direct, Bluetooth and NFC.

Broadcom is sampling 5G WiFi solutions to its early access partners including retail and PC OEMs, service providers and carriers, and will be demonstrating 5G WiFi capabilities at CES.

802.11ac has generated broad support across the consumer-electronics industry. Companies and partners across the ecosystem recognize that 802.11ac is the future of Wi-Fi and are committed to its development, integration and distribution.

I'm all for technological advancement and of course I want 1Gb's WIFI, but im ever increasingly worried about all these new radio technologys and their invisible effect on our lives.

There is no sufficient scientific knowledge to this day on the real effects of the electromagnetic radiation from radio waves, but there is and ever increasing amount of radio technologys being produced and rolled out around the globe. Studies show temperature increases in tissues (think of a microwave oven here for an example but on a far lesser scale). Plants and tree growth has also been shown to be affected by this. Humans too have been shown to develop tumours and mystery illnesses but proving this has always been hotly debated as there is so much money involved around these technologys and a lot invested in developing them (think of the old tobacco companies when it was safe to smoke).

Bee's are a hugely important part of the ecosystem and they too are badly affected by radio waves, and thats definately not something to take lightly considering that they are the main pollenators of crops and plants around the globe.

Anyways im no eco-nut, but technologys like this where the full effects arent completely understood are dangerous in my mind and probably shouldnt be rolled out to such a large scale globally. (im not talking specifically about Wifi here just for the record)

so how does this work, is it a wifi replacement, or a 3G replacement?

if its meant to do both at once that could go horribly wrong, with a persons home wifi connection interfering with a neighbours roaming 5G connection


if its purely wifi, why the confusing name after 2/3/4G are all roaming solutions?

The G stands for Goodness.

ugggh reading it again, i see their goal. theres going to be 5G, and 5G wifi. and devices will support one, the other, or both.


in an attempt to make things simpler for consumers, they're just going to make it even more confusing.

"ac?" We going to double-character names now? 802.11a, b, g, n were OK. And what does the "ac" stand for anyway? (I suppose I should go to the website huh LOL)

The "ac" is for "air conditioning" because it's so damn cool

I was surprised at first to see 80MHz channel bandwidth, I mean in the 2.4GHz band that would pretty much use the entire band (room for only 1 channel) as it only runs from 2.400 to 2.4835 (at least in north america). Then I read a bit more and it looks like it will only be 5GHz, so range is going to be ultra crappy

Yeah, I think they usually mean Generation with G, as in 5th generation, I don't know if this makes any sense:

cell tech
1G : Analog, 2G: digital (CDMA/TDMA/GSM) 3G: UMTS/HSPA 4G: HSPA+/LTE
wifi tech (802.11)
1G: a 2G: b 3G: g 4G: n 5G: ac

Probably though just an attempt to generate interest / marketing hype by making it sound like a cell phone technology, since cell phones are so interesting these days.

"ac?" We going to double-character names now? 802.11a, b, g, n were OK. And what does the "ac" stand for anyway? (I suppose I should go to the website huh LOL)

It's just the way the IEEE numbers them, once they get to z then they go to aa, then once they get to az they go to ba, etc. Once they get to zz we'll probably have aaa I guess.

Personally, I keep my wireless modem away from my sleeping room, just because of this. I also never keep my mobile phones close to the heart or head when sleeping or walking...
