Broadcom is up to 3 in Japan following the 2012 International CES on the 19th..Wireless LAN standard that realizes 6Gbps "IEEE 802.11ac was explained.
IEEE 802.11ac (hereafter 11acc) is a Wi-Fi standard that is the successor to the current 11N.First IEEE 802.Since it is the fifth generation counted from 11, it has also been nicknamed "5G WiFi".According to Michael Haarton, the company's senior vice president and general manager, the 11ac aimed at three expansions, bandwidth, capacity, and connection distance.
Needless to say, the ratio of videos in internet content is increasing, and it is necessary to expand the bandwidth to make the video even higher.Around 2008, Wi-Fi, which was installed only on smartphones, PCs, and game equipment, is expected to spread to TV, cameras, STB, and cars by 2013.Only the capacity is required.At the same time, as the number of devices increases, the place where they are placed expands, and the distance is far, so the connection distance must be improved.
Specifically, 11AC has a bandwidth of 6 times to 11n..It became 6Gbps, the number of simultaneous connections increased, and the connection distance improved by about 30 % to 3 times.It is said that power consumption efficiency has improved six times.However, in the product announced by the company this time, the largest theory bandwidth is 3 streams..Until 8Gbps.Still, 1 at the effective speed.It sings 3Gbps and exceeds the wired LAN for consumers.

According to the materials shown by Halston, the distance of 100Mbps communication required for file synchronization between devices is 30m for 11n, but up to 80m on 11ac, 50Mbps necessary for watching HD videos.In communication, 11n can be connected to 50m and 11ac can be connected at 100m (both are 5GHz, 11n is 2 streams, 11ac is connected in 3 streams).
In addition, 11ac is only 5GHz, but the company's products are dual bands, 2..It also supports the operation at 4GHz/11n.
At the moment, 11ac is a draft stage, but it is expected to be an official version in 2012, and 14 companies, including Buffalo, Asustek, Lenovo, LG, Microsoft, D-Link, NetGear, ZTE, Motorola, Belkin, Huawei.Has announced the recruitment.
Mr. Nakamura, Deputy Director of Overseas Business Department, who performed the world's first demonstration at CES, also explained, following 11G and 11n, aiming to be the world's first commercialization of 11ac, aiming to ship in the United States in 2012.He said.The first product will be draft compatible, but once the official version is completed, the firmware update will respond promptly.
Although it was not stated in this briefing, the product shipment is expected to be shifted after 2013 because the Ministry of Internal Affairs and Communications has not been approved by the Ministry of Internal Affairs and Communications on 11ac.
