Broadcom’s BCM4359 Can Actually Use Both Wi-Fi Antennas Simultaneously, and Might be Inside Your Next Smartphone

March 9, 2015 - Written By Phil Bourget

The ‘Internet of Things’ is a concept that has been around for a while, especially popular among folks when the various parts of your house got new model iterations with Wi-Fi, Bluetooth, or a data connection.  But, the IoT, as it’s called, continues to grow, and become more efficient and competitive with connection.   And, as with every year, a company has stepped up and brought us a new wireless chip, and this year it’s Broadcom with their BCM4359.

This new chip for 2015 looks to optimize your connection to both the Internet as well as within your own IoT.  Specifically, this chip can manage, and is the first to actually do this, a true dual-band connection instead of needing two separate antennae.  The connection that your smartphone has allows, normally, for a Wi-Fi connection to get you Internet access or be able to share something via Wi-Fi direct with you TV for example.  With the BCM4359, a smartphone will be able to use one channel for the direct connection to another device while using the other channel for an actual Internet connection via Wi-Fi.  And that’s the key, but there’s still more about the 4359 that makes it an even greater addition to this year’s smartphones-to-come.

With the new modem from Broadcom, a device can utilize both a 5 and 2.4 Ghz connection to get better speeds and performance and, with Broadcom’s Narrow Band technology, the range can be doubled for greater spans between devices.  With the use of DFS, dynamic frequency selection, the 4359 can use the best connection consistently, to produce better and less interrupted connections and speeds.  The 4359 features the aforementioned Real Simultaneous Dual Band (RSDB) capability of utilizing both of its antennae separately or together, as well as an FM radio and Bluetooth 4.1 connectivity.  The modem comes with 802.11ac capabilities, so speed will not be an issue if you have a router than can produce, support, and handle the speeds the BCM4359 can get to, which are up to 867 megabits per second in MIMO mode.

With smartphones getting ever-better, and the Internet and its files getting ever-bigger, the improvements made with their connectivity is just as, if not more, important.  With data speeds getting so much faster as years go by, from 3G to Category 9 LTE, Wi-Fi is often overlooked, but can be more important, especially for home users or folks without great cellular reception.  How often do you use your smartphone as a Wi-Fi control hub, getting connection and sharing media with another device at the same time?  Do you think that with more possibility to connect via Wi-Fi, more things will come with that capability?  Let us know down below.
