Qualcomm mobile electronics manufacturer has announced a new line of chips, whose work will allow future portable electronic devices to achieve data rates in wireless mode, up to 1.3 GB / sec. As described in Qualcomm, the company plans to release a line of solutions for mobile and desktop computers and network equipment. It is expected that new products with support for superfast networking standard WiFi 802.11ac will be sold on the market in early 2013. Recall that earlier decision to support 802.11as began producing Broadcom, a manufacturer of networking products D-Link announced support for this standard. 802.11 Al is an upgrade of the existing specifications of 802.11n, also known as Wireless N, and is positioned as a solution for network share information in a “post-PC era.” It is expected that based on this technology will work many home electronic devices.

Data rate of 802.11n is 450 Mb / s to 1.3 Gb / s, depending on the particular device. Today, wireless technology specification 802.11ac are still in development, but despite this, the first products based on this technology have will be on the market by the end of 2012. Wi-Fi Alliance to certify the device will start with support for 802.11ac the fourth quarter of 2012. Despite this, the first 802.11ac products can be sold by mid-year. The first products will not be officially certified, but they will be provided an opportunity to rewrite to be compatible with a standardized version of 802.11ac. standard provides for the simultaneous use of three radio channels for synchronous data transmission. Each radio provides 350 Mbit / sec, which is higher than the current standard, 802.11n.

It is expected that the equipment with a single radio channel to be used in mobile devices, while the three – in the steady-state solutions. achieve growth in the capacity of the new technology was possible thanks to a range of mechanisms, including the wider radio channel, the frequency band which has been extended to 80 MHz. Also here were introduced more advanced modulation schemes and the direction of the radio flux. Also, the new standard uses the less loaded 5-GHz band, which is still less loaded than the 2.4-GHz, where sit the majority of modern WiFi-transmitters. In addition, given the faster data transfer rate is reduced when using converters and increased energy savings.
