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.
• 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.

Wi-Fi-enabled devices will grow from less than 1 billion units in 2010 to more than 3 billion in 2015. Given the current constraints of legacy 802.11 standards and the increased speed, capacity, coverage and battery life that 802.11ac offers, this next generation of Wi-Fi is poised for rapid growth across all product segments. 802.11ac will be one of the most influential mobile and wireless technologies in the years to come.

As demand for connectivity solutions continues to rise in Asia, consumers are looking for a fast and reliable Internet experience. 802.11ac will be especially beneficial in this region where materials such as concrete are common in buildings and offer unique challenges to delivering reliable Wi-Fi coverage. We anticipate that the innovations reducing dead spots and improving reliability throughout the home will appeal to consumers and will help drive rapid adoption of the technology.
