According to The Next Web, Apple already has some news prepared for the Macs that are presented during this year that has just begun. It is about the incorporation of a wireless chip that allows them be compatible with the 802.11ac wireless standard.
The agreement could have been made with the Broadcom company that would supply all the chipsets responsible for making this wireless communication possible on Macs. What improvements does this version bring? Theoretically, we are talking about a technology capable of treplicate the speed of the 802.11n protocolIn other words, it would support individual links of at least 500Mbit / s, which represents a very significant increase in bandwidth for transferring large files or making use of high-quality streaming services.
Although the 802.11ac wireless protocol is still under development, it is expected that it can also reach mobile devices such as the iPad, iPhone or iPod Touch. This would be done by the Broadcom BCM4335 chipset which was presented in July and that combines 5G WiFi technology, Bluetooth 4.0 and FM radio in the same component.
We will see what is left of this technology that promises to reach our homes during this year 2013.
