Broadcom announces the new low power consumption combo chip for smartphones that supports 3 times faster wireless LAN 802.11ac

Wireless LAN combo chip for smart phones and tablets that can increase the communication speed while reducing power consumption to extend battery life and also can connect with Bluetooth 4.0 and receive FM radioBCM 4335"Was announced by Broadcom.

This wireless LAN chip is a new standard for wireless LANIEEE802.11ac, And achieves communication at a maximum of 433.3 Mbps (theoretical value during one stream communication). One generation agoIEEE802.11nIn comparison with the maximum communication speed of 150 Mbps under the same conditions, almost faster speed has been achieved. Moreover, since it has compatibility with the old standard 11a / b / g / n, it can also connect to existing wireless LAN network.


In addition, it can also be used for "Wi-Fi Direct" which connects other devices by using a terminal equipped with this chip as an access point, "Wi-Fi Certified Miracast" which can display contents by directly connecting to a large screen TV etc. Correspondence. "Wi-Fi CERTIFIED Passpoint" that keeps connecting seamlessly while moving between wireless LAN access points is also available, so it is also a powerful off-road destination for 3G networks for mobile phones that are concerned about communication problems due to congestion is. In addition to the power consumption reduction function at idle time, you can extend the battery driving time by shortening the data transmission / reception time by increasing the communication speed and enabling the terminal to enter the idle mode quickly.

In addition,BCM 4335"The shipment time of the first quarter of 2013 is so, it starts with a spring model smartphone of the same year and 4th generation iPad (provisional) starting installation.

By the way, although "BCM 4335" announced this time is not supported, 5G WiFi itself like IEEE 802.11n, "MIMO (Multiple Input Multiple Output)" which combines multiple antennas to increase the data transmission / IEEE802.11ac is the fifth generation counted from the first IEEE802.11, as can be seen from the figure below, as it can be seen from the figure below that it corresponds to the maximum 6.93 Gbps (theoretical value) It seems that it was named "5 G" by Broadcom.


As a product compatible with "5G WiFi", the parent device of the stationary type wireless LAN routerWZR-D 1100 H(17,800 yen including tax) "is being released from Buffalo.


Since overseas products have been announced more than one, it seems that there will be some momentum for popularization as smartphones' 5G WiFi compliance progresses.
