Broadcom Announces New 5G 802.11ac Wi-Fi Chip Designed for Smartphones
Broadcom recently announced a new 5G 802.11ac Wi-Fi chip specifically designed for smartphones. The new chip is capable of data throughput speeds of up to 650 Mbps, the BC4358 is Broadcom’s second chip to use 2x2 multiple input multiple output (MIMO). This brings up to twice the Wi-Fi performance with 25% more power efficiency than 1x1 MIMO chips.
For those of you who didn’t already know, MIMO is a technology that utilizes multiple antennas to help both the transmitter and receiver when it comes to improving communication performance. The Cupertino California company seems to have adopted MIMO technology in both the iPad Air and the iPad mini with Retina display.
Broadcom mentioned that the new chips were already in production and will begin shipping in smartphones during the third quarter of 2014 which means that the chip may be found in the iPhone 6 as well. The BCM4358 chip includes improve location accuracy that’s accurate “down to one meter” for better indoor location-based services. This appears to align with Apple’s own indoor mapping goal as well. Broadcom’s new chip is also the first to enable Angle-of-Arrival direction finding technology, which is another feature that Apple could potentially take advantage of.
As of right now it’s unknown if Apple’s iPhone 6 will use the specific chip but Broadcom is one of Apples partners as it supplies both its desktop and mobile device chips. We’ll have to wait and see as we’ll be finding out at Apple’s September 9th media event.
