New chipset allows for better communication in congested environments
Semiconductor solutions provider Broadcom today introduced the industry's first 5G Wi-Fi (802.11ac) 2x2 Multiple Input Multiple Output (MIMO) system-on-a-chip (SoC) for smartphones. The Broadcom BCM4354 SoC will enable manufacturers to deliver twice the Wi-Fi performance of 1x1 MIMO devices used in smartphones today while improving system power efficiency up to 25 percent when using wireless applications.
In addition, Broadcom's Transmit Beamforming (TxBF) technology further improves rate over range performance in congested environments for data-intense applications. Photo and video uploads to social networking sites, for example, will be twice as fast in crowded sporting events or concert venues when the chipset is widely adopted.
A version of Broadcom's BCM4354 SoC supports Rezence wireless power technology, developed by the Alliance for Wireless Power (A4WP) which delivers additional options for charging for so-equpped devices. All versions feature a full software platform, including support for Android, Windows and Chrome-based operating systems.
The chipset is in production now. It is not known if this is the chipset in the new Galaxy S5 handset, but the performance metrics seem similar at first glance.
